Product Description

HBB High Performance Single Row 4 Point Contact Ball Bearings

Normally, Slewing Bearings are large-size rolling bearings that can accommodate axial,radial and moment loads acting either singly or in combination and in any direction. They can perform both slewing (oscillating) movements as well as rotational movements.

Basically, a slewing bearing consists of an inner ring (a), an outer ring (b) and rolling elements − balls (c) or cylindrical rollers − that are separated by polyamide spacers (d). The rings, 1 of which usually incorporates a gear (e), are provided with holes (f) to accommodate attachment bolts. The holes may be threaded. Generally, only the raceways in the rings (h) are hardened and precision-ground. Integral seals (g) made of acrylonitrile-butadiene rubber (NBR) keep the lubricant in, and contaminants out of the bearing. Slewing bearings are re-lubricated Slewing bearings through grease fittings (i) to reduce maintenance and operating costs.

Compared to traditional pivot arrangements, slewing bearing arrangements provide many design and performance advantages. The compactness and large inner diameter simplify the design of the bearing arrangement and its associated components.

The low sectional height of these bearings means that the pinion lever can be kept short. In most cases only flat surfaces on the associated components are needed.
Slewing bearings were originally designed to be mounted only on horizontal support structures, but can now be used successfully in vertical bearing arrangements. The forces and load distribution in slewing bearings, when subjected to axial, radial and moment loads.

Technical Speficiations:

Slewing bearings perform extremely well in a variety of applications such as:

Types of Ball Bearings

Modern ball bearing configurations have different materials and geometries to meet the demands of different working environments and applications. There are different types of ball bearings: single row deep groove, double-row deep groove, angular contact ball bearing, thrust, and self-aligning. Let us look at the differences between each type and learn why they are important for various purposes. Listed below are some of the most common types of ball bearings.

Miniature bearings

Although miniature ball bearings are a popular choice for small mechanical components, they are not without their challenges. They must be properly lubricated and stored in clean rooms. A strand of hair could ruin a miniature bearing. Fortunately, manufacturers offer lubrication services and a “Clean Room” for customers to store their miniature bearings safely. Read on to learn more about these small bearings and how they can help you.
The size of a miniature ball bearing can vary significantly, but most types of these devices are available in sizes ranging from.040 inch to one eighth of an inch. Whether you need a small ball bearing for a miniature car or a tiny instrument, a miniature bearing can save space while still offering high performance. Many of these bearings are shielded to prevent dirt from entering and leakage of lubricant. They can be flanged or unflanged, and some miniature ball bearings have extended inner rings that are designed for easy plate mounting.
Miniature ball bearings are commonly made from stainless steel or chrome steel. Both metals have their advantages. Stainless steel is the most popular material for ball bearings, which allows for a high load capacity while being quiet. Because stainless steel is relatively inexpensive, many small instrument bearings are made entirely of stainless steel. The difference in price is minimal, as the amount of steel is relatively small. Stainless steel miniature bearings are the smallest and lightest of all types of miniature ball bearings.

Self-aligning ball bearings

bearing
In the simplest terms, self-aligning ball bearings are ball bearings with flex shafts. If you’re looking for a ball bearing with a high degree of precision, you’ll want to choose one with a flex shaft, which means it can adjust to the proper orientation of the bearing’s flex shaft. Ball bearings with flex shafts are also recommended. But, what are these bearings?
Self-aligning ball bearings are made with two rows of balls and a common sphered raceway on the outer ring. As a result, they can accommodate small errors in shaft alignment and mounting. The CZPT brand is especially suitable for high-speed applications requiring greater running accuracy. The self-alignment mechanism is enabled by the fact that the balls are placed in two rows on either side of the sphered raceway in the outer ring. These two rows of balls also promote reduced friction and wear.
Another type of self-aligning ball bearings is a double-row design. They feature a common sphered raceway on the outer ring, a hollow spherical ring, and a cage that rotates relative to it. A self-aligning ball bearing is used in applications where shaft misalignment is a problem, such as conveying equipment. They are also used in simple woodworking machinery and ventilators.

Ceramic ball bearings

Ceramic ball bearings have several advantages over steel or metal bearings. These include increased acceleration capability, reduced friction, improved wear-resistance, and higher speeds. The United States holds the leading position in the global ceramic ball bearings market thanks to a rebounding motor vehicle production and healthy fixed investment environment. In the United States, there are three primary markets for ceramic ball bearings: healthcare, automotive, and aerospace. Here are the main benefits of ceramic ball bearings:
Hybrid ball bearings are also available. Hybrid bearings feature traditional metal rings and silicon nitride (ceramic) balls. Hybrid bearings offer important performance advantages over all-steel bearings, and they are more affordable. However, full ceramic ball bearings have all ceramic parts, and are best suited for machines that require high precision. These types of bearings also resist corrosion and wear.
Compared to steel ball bearings, ceramic balls are lighter than steel. They are also less dense, which means less friction and therefore less heat. Additionally, ceramic balls operate at higher speeds than steel balls, which increases their durability and longevity. But they are still not as strong as steel bearings. And because of their reduced density, they are much cheaper to manufacture. Therefore, they are an excellent choice for many applications. You can expect them to last much longer than steel bearings.

Steel carbon ball bearings

High precision G25 ball bearings are made of the highest grade chrome steel and hot forged from bar stock. Statistical process control and exacting atmospheres help ensure uniform hardness and microstructure. Moreover, these bearings are of the highest quality, with fine surface finish and a tight tolerance. This makes them the most widely used and reliable choice for industrial and automotive applications. However, there are some considerations that should be taken into account before acquiring a steel carbon ball bearing.
Generally, AFBMA grade 200 is the standard hardness specification for this material. AFBMA grade 100 can also be obtained with great difficulty. Despite the high hardness of steel carbon ball bearings, their outer surface is just a thin hardened shell, so a special micro hardness test is needed to evaluate them. In addition to the hardness, steel balls are easily machined and ground. Some manufacturers even offer stainless steel ball bearings and ball sets.
Another factor that makes steel carbon ball bearings so valuable is their precision. They can give precise measurements, which makes them ideal for low and medium-speed applications. Due to their high precision and durability, steel carbon ball bearings can be used in many applications, from conveyor machines to roller skates. However, you should be aware that the material used to produce these bearings is not suitable for applications in which they are exposed to water and gases. Further, they are also noisy and heavy, and must be installed properly in a manufacturing environment.

Stainless steel ball bearings

bearing
Stainless steel ball bearings are made from a high-quality type of stainless steel, 440C, which offers optimal corrosion and abrasion resistance. These bearings are also durable and rust-free, and are suitable for a variety of applications. Among others, stainless steel ball bearings are used in beverage and food processing plants, pharmaceuticals, pulp and paper mills, marine environments, and freezers.
Stainless steel bearings are available in various grades. For example, AISI 440C offers corrosion resistance, while the DD400 is specifically designed for marine applications. Both types of stainless steel are available in different forms, including open, shielded, and sealed. Stainless steel ball bearings can also be custom-made, as BL is known for producing customized bearings. There are also other materials that are available.
AISI type 316 stainless steel balls are ideal for marine applications and food processing. They have excellent resistance to most organic materials and are also used in medical devices and dispenser pumps. They are also strong enough to resist many petroleum products and are widely used in medical equipment and cosmetic applications. In addition, stainless steel balls can be plated to provide an additional layer of protection against chemicals. To understand how they differ, let’s take a look at some common types of stainless steel ball bearings.

Stainless steel

Stainless steel ball bearings can be used in various applications. Besides being corrosion resistant, they also last longer thanks to the Molded-Oil lubrication technology. Stainless steel ball bearings are clean units, which saves time and money in terms of maintenance, replacement, and downtime. But what are the advantages of stainless steel ball bearings? Let us discuss these benefits. Also, we’ll discuss their advantages and disadvantages.
Stainless steel ball bearings offer notable advantages, including corrosion resistance, increased strength, and improved stability under high temperatures. These qualities make them the ideal choice for special circumstances and demanding environments. However, you should be careful when choosing stainless steel bearings. There are several different types of stainless steel. Here’s a brief look at what makes them the best choice. And remember: Stainless steels are also recyclable. In fact, they can be recycled indefinitely.
They’re made from chrome alloy electric furnace steel, which is hardened for optimum service life and strength. They have the highest surface finish and dimensional accuracy. Advanced heat-treating processes increase their strength and anti-cracking abilities. And thanks to their unique materials, they’re corrosion-resistant. As a result, they’re more durable than other types of bearings. And since they’re made with a high-quality steel, you’ll save money in the long run.

Plastic ball bearings

bearing
Plastic ball bearings were developed to meet the specific needs of applications where standard steel bearings would fail. Steel and 440C stainless steel are both susceptible to rusting when exposed to water, making them poor choices for applications involving food processing, swimming pools, and medical equipment. In addition to this, the plastic material is able to dampen vibrations and make the bearing virtually silent. Here’s what makes plastic ball bearings so great for these applications.
Plastic ball bearings are lightweight, corrosion-resistant, and offer a long service life. In addition to their low price, they can be easily cleaned and are incredibly durable. Motion plastics specialist igus has recently expanded its range of xiros polymer grooved ball bearings. These bearings are also FDA-compliant, lubricant-free, electrically insulating, and resistant to both temperature and media.
Plastic bearings are often mounted into other components like wheels, pulleys, and housings. In this way, the inner ring is essentially a profile of the pulley’s profile, and the outer ring is a shaft or fixing clip. The result is seamless integration of the bearing and the surrounding parts, which reduces the overall assembly time and costs. You can also use multiple plastic ball bearings in one application for more options.

Kinds of Ball Bearings

There are numerous types of ball bearings: Double-row angular contact, Four-position contact, Self-aligning, and Ceramic hybrid. Here’s a brief description of each and every. For far more information, go through our post about Double-row angular contact ball bearings. You are going to be greater educated about how they are created. Also, discover about how the cages that keep the balls in spot are secured with rivets.

Double-row, angular-speak to bearing

Double-row, angular-speak to ball bearings are equivalent in their contact surfaces in one direction, and the two pairs of bearings are set up axially reverse to one one more. This style allows them to assist blended loads in axial and radial instructions. These varieties of bearings are utilised for large-precision, higher-pace applications. They can be used in every little thing from turbines to dentistry products. Double-row, angular-get in touch with bearings are accessible at Grainger, as are one-row versions.
Double-row, angular-speak to ball bearings are a well-liked option for programs where substantial precision and large speed are essential. The layout functions of these bearings are ideal for purposes with axial area limitations. In distinction, they are smaller sized than two one-row angular-make contact with bearings and are offered in steel, polyamide, or brass cages. Whether or not you need to have a cage for high velocity or challenging working problems is up to you. If you are uncertain about the correct cage for your software, get in touch with Schaeffler.
One-row angular-make contact with ball bearings are the most typical kind of bearings. Double-row bearings are also accessible with a shielded outer ring, which safeguards the balls inside the bearing from external contaminants. Simply because these double-row bearings are a good selection for apps requiring large functionality, they are often the most reasonably priced option. They provide comparable efficiency as one-row bearings but are considerably much more rigid.
Preloading is a important overall performance characteristic for double-row angular-get in touch with ball bearings. Preloading can decrease the service daily life of double-row angular-speak to ball bearings by up to 380 percent. Alternatively, you can preload double-row angular-contact ball bearings by putting spacers amongst their outer rings. Good double-row angular-make contact with bearing installation will increase functioning precision and bearing existence.
bearing

Four-position contact ball bearing

The 4 Point Make contact with Ball Bearing Marketplace can be segmented into 3 kinds: 35 Degree, forty five Degree, and Other. The 35 Degree section is envisioned to witness the swiftest growth over the up coming couple of a long time, owing to its elevated operational pace and competence in axial and radial axis load managing. Other types of 4-position get in touch with ball bearings incorporate the Miniature and Deep Groove types. These are extensively used in cars, aerospace, and other industries.
These bearings are created for oil-totally free screw compressors, and they characteristic an outer-ring guided brass cage to minimize friction and boost managing accuracy. In addition, they have decrease upkeep expenses in comparison to conventional bearings. However, they have a increased indicate roughness benefit than their counterparts. Large-speed functions require substantial-pace bearings that can withstand rapidly pace adjustments. This is simply because of the higher friction charge, which outcomes from four-position speak to.
The 4-Stage Get in touch with Ball Bearing is a extremely versatile product, as it can deal with radial, thrust, and moment masses. Simply because of this, it is usually the initial selection for slow to reasonable-velocity programs. This design and style also has a simplified assembly method, requiring only a solitary double-50 %-change to put in. It is the initial choice of numerous automotive OEMs simply because it is very productive. If you want a ball bearing with these rewards, you should contact a local bearing organization.
The 4-Stage Speak to Ball Bearing Industry will proceed to develop despite a hard economy and risky trade situations. Demand from customers for automotive and aerospace factors is expected to increase alongside a assortment of technological advancements. In the meantime, demand from customers for power-efficient products will keep on to increase with changes in trade coverage, an imbalance in the offer-side ecosystem, and geopolitical threat. And even though all these variables will keep on to travel the industry growth, a number of problems are really worth taking into consideration.
The 4-Stage Get in touch with Bearing is created with the very same fundamental composition as its two-position counterpart. In a four-point get in touch with ball bearing, a single ball can have 4 unique factors of make contact with with two rings. Two of these make contact with factors may be in diagonal position. The two remaining contact factors alter place and accommodate radial hundreds. For that reason, the Four-Stage Get in touch with Bearing is more versatile and sturdy than its two-level counterparts.

Self-aligning ball bearing

The self-aligning ball bearing is an incredibly useful instrument in a lot of industries. This type of bearing has a sealing lip that helps make get in touch with with a clean chamfer on the interior ring. Because of the self-aligning mother nature of these bearings, they are not susceptible to misalignment. They can face up to temperatures ranging from -30°C to 120°C and should not be heated prior to installation.
A self-aligning ball bearing is an elastomer-primarily based spherical-shaped bearing with two rows of rolling components. These bearings can accommodate big radial loads, and their outer ring raceway is curved to give a spherical result. The inner ring, or cage, can be both cylindrical or conical. The internal diameter of a self-aligning ball bearing is normally cylindrical, but some are conical. They normally have 3 oil holes.
When deciding on a self-aligning ball bearing, search for a design with a big enough bearing diameter to accommodate the shaft’s bending. Self-aligning bearings may also be interchangeable with standard ball bearing assemblies. You can uncover specific values in maker catalogues. These bearings are useful in restricted purposes, despite the fact that they are not automatically ideal for everything. For case in point, in purposes exactly where combined masses are the major problem, self-aligning ball bearings must only be used if the software demands small misalignment.
A self-aligning ball bearing is a extremely-successful, strength-productive solution for a range of purposes. It is a simple, reduced-servicing remedy that can make your life less complicated. Its special outer raceway enables restraining springs to take up the deflection that is typical in other bearings. The end result is a cooler, smoother running vehicle. It also helps stop misalignment, which makes it best for use in numerous programs.
The SKF self-aligning ball bearing is an superb choice for applications involving hefty deflection of the shaft. They are the lowest-friction bearing accessible. Their metal plate bolstered seals stop them from separating from the shaft during procedure. They are also resistant to oil, creating them the perfect solution for higher-pace purposes. In addition to this, they are developed to function in a extensive assortment of temperatures.

Ceramic hybrid ball bearing

A hybrid ball bearing created from a mix of steel and ceramics is a good option for high-pace programs demanding electrical isolation. This mixture delivers an extended lifespan and minimum electrical corrosion or seizure chance. In addition, the hybrid ball bearings have much less friction than metal bearings and can run at minimal speeds. To discover much more about this hybrid kind of bearing, continue studying. We will also examine how it can help your software.
Total ceramic balls are generally more challenging than steel, but they do have reduce density, which means they’re not subject matter to the same large centrifugal forces as steel balls. These positive aspects make ceramic ball bearings significantly a lot more sturdy, with long lifespans. The two entire and hybrid ceramic ball bearings are offered from CZPT. Go through on to learn more about each and every variety. Here’s a look at some of the advantages of every single. You may be pleasantly surprised.
A hybrid ball bearing is made up of steel internal and outer rings and a ceramic ball. It can stand up to large speeds and masses, but it is also created to work in intense temperatures. This hybrid ball bearing also needs minimum lubrication and is suited for a selection of purposes. Because of its exclusive attributes, hybrid bearings are lightweight and challenging, and they spin quicker than steel balls. But how do you decide on the correct a single for your application?
A ceramic ball bearing is far better than a metal 1 for many purposes. Its higher speed capability and lower friction let it to run at increased speeds than steel balls. It is also considerably less sensitive to fluctuations in lubrication conditions than metal balls. They also are likely to be cheaper, so it can make feeling to invest in 1. It truly is really worth your while. They last longer, and they never demand a run-in time period.
A hybrid ball bearing is the greatest choice for electric powered spindles with large speed and hefty loads. A hybrid ceramic ball bearing has the edge of low heat and high stiffness, and can run at substantial speeds and hundreds. This thesis explores the dynamic characteristics of a hybrid ceramic ball bearing, including investigation calculations and experiment verification.

Types of Ball Bearings

In their most fundamental sort, Ball Bearings have 1 common feature – they are produced of steel. The vast majority of these bearings are produced of 52100 steel, which has one per cent chromium and one p.c carbon. The steel can be hardened by heat trea
tment. 440C stainless steel is utilised for rusting troubles. A cage about the ball balls is traditionally produced from thin metal. However, some bearings use molded plastic cages to preserve income and friction.
bearing

Single-row patterns

Metal linear translation levels often use single-row patterns for ball bearings. These varieties of bearings give sleek linear journey and can stand up to large loads. The content metal has a large modulus of elasticity and a large stiffness, as well as a reduce thermal enlargement than aluminum. For these motives, steel is the materials of decision for a ball bearing in a common consumer setting. One-row patterns for ball bearings are also suited for applications in humid or corrosive environments.
Single-row styles for ball bearings are obtainable in a assortment of sizes and are axially adjustable. They have a large radial potential, but require fairly little place. One-row deep groove ball bearings with snap rings are STN 02 4605 or R47, respectively. Bearings with snap rings are recognized by a suffix this kind of as NR. They may not have seals or shields mounted.
These solitary-row angular make contact with ball bearings are able of supporting axial and radial masses. In a two-raceway arrangement, the radial load on bearing A causes a radial load to act on bearing B. Equally axial and radial forces are transmitted in between single-row angular speak to ball bearings, and the resulting interior power need to be taken into account to determine equal dynamic bearing loads P.
Single-row deep groove ball bearings are the most typical type of ball bearings. These bearings are developed with only a single row of rolling aspects. The single-row design is straightforward and durable, which can make it best for higher-speed apps. Solitary-row designs for ball bearings are also offered in various bore measurements.
