They can operate at large speeds and can carry radial and (restricted) axial masses. They are frequently utilized in electric powered motors, compressors, followers, and conveyors.WHAT ARE THE Benefits OF DEEP GROOVE BALL BEARINGS?Flexibility – simply because they can have radial and axial hundreds, they have a broader assortment of purposes for numerous industriesCost personal savings – deep groove ball bearings develop much less friction torque. This lowers running temperature (which extends the daily life of the bearing) and lowers energy expense of running equipment (such as conveyor belts).Much less maintenance – due to the fact of their basic style, minimal operating temperature, and lower friction, deep groove ball bearings have a for a longer time anticipated shelf existence than other bearings. They do not demand additional lubrication after installation, which also indicates much less upkeep downtime.WHAT INDUSTRIES USE DEEP GROOVE BALL BEARINGS?Several INDUSTRIES Gain FROM THE USE OF DEEP GROOVE BALL BEARINGS:AgriculturalFood ProcessingMachine ToolMaterial HandlingMedical / PharmaceuticalPrintingRailway and TransportationWind EnergyTypes of Deep Groove Ball BearingsManufacturers have refined the design and style of deep groove bearings in excess of the a long time, resulting in many distinct types. These varieties are typically greater suited to a distinct software exactly where a deep groove bearing isn’t ideal.Single-Row Deep Groove Ball BearingsThis is the normal deep groove ball bearing that has a single raceway. These are normally robust and manufactured from tough supplies, guaranteeing that these bearings have an prolonged provider existence.Single-row deep groove ball bearings are also subdivided into other types, ranging from 3 mm to four hundred mm bore measurements, ideal for almost any software. Some companies will also supply slim, slim, wide, or miniature bearings dependent on clients’ demands.Since deep groove ball bearings need to stand up to excessive situations, manufacturers also supply ceramic-coated bearings to handle electrical pitting and higher-temperature units that can stand up to up to 660 levels F.One of the most recent developments in solitary-row deep groove ball bearings is the sensor-bearing unit, Backyard garden tiny tractor PTO farm rotary hoe tiller which can evaluate the status of the ball bearing elements. These units are easy and easy to use and can help with pace sensing, angular situation measuring, and steering, generating them useful in electric powered motors, tractors, conveyors, and road rollers.Sealed Deep Groove Ball BearingsSealed deep groove ball bearings are similar to one-row bearings, apart from that they have steel or rubber shields mounted on 1 or equally sides of the bearing. These seals are pre-lubricated with grease to extend the lifespan of the bearing.Many companies utilized sealed ball bearings in contaminated environments that may possibly in any other case impact the performance of the bearing. The shields aid the bearing keep grease whilst also preventing any contaminants from getting into the bearing by itself.Bigger deep groove ball bearings may even use machined brass cages for higher-pace purposes, exactly where the cage stops unwelcome use and tear.Flanged Deep Groove Ball BearingsSome deep groove ball bearings come with a flanged outer ring, which operates likewise to a snap ring on common ball bearings. The flange enhances the bearing’s operating efficiency and is also less difficult to machine due to the simplicity of the housing bore.Flanged deep groove ball bearings are outstanding for bearing axial masses, such as in tube ends or on belt CZPT rollers. Some variants even have swivel housing to allow for slight misalignments and far better axial loads.Double-Row Deep Groove Ball BearingsThe double-row design and style enables for a considerably larger load carrying capacity even though nonetheless retaining the bearing’s lower friction characteristics. Double-row bearings are usually just somewhat wider than their single-row counterparts, creating them almost as functional and useful.The major disadvantage of double-row deep groove ball bearings is that they do not arrive with seals or shields, although some may possibly be fitted with cages. These cages aid with installation and assembly but are inclined to mechanical stresses in the course of operation. It’s crucial to pick the proper sort of cage for the distinct software, specially as some cage resources are sensitive to specific lubricants.Maximum Kind Ball BearingsThese ball bearings have numerous far more rolling components than their solitary and double-row counterparts. These further balls permit for increased performance and greater precision with no sacrificing efficiency or longevity. Like solitary-row deep groove ball bearings, they can be possibly open or shielded, dependent on the software and demands. The Advantages of Deep Groove Ball BearingsDeep groove ball bearings have several rewards above classic ball bearings. These consist of:Potential to Carry Radial and Axial LoadsOne of the most significant drawbacks of conventional ball bearings is their lack of ability to bear axial loads. Most deep groove ball bearings can handle about fifty% of their radial load in the axial airplane, although some more compact bearings can only deal with close to 25% of the radial load. This capability to bear axial and radial hundreds makes deep groove ball bearings extraordinarily flexible and has produced them well-known in a vast selection of industries.Minimal FrictionDeep groove ball bearings generate considerably less friction than regular bearings, which translates to value cost savings in several techniques. To begin with, it lowers the operating temperature of the bearing, which extends the lifespan of the bearing. It also can make it less expensive to operate the equipment with the bearing because of to increased efficiency and decreased upkeep specifications. Reduced friction also final results in decreased sound and vibration, producing these bearings best for high rotational environments, the place they will use much less lubrication than their standard counterparts.Straightforward to InstallDeep groove ball bearings are straightforward to install, which leads to simplified assembly and greater load potential. Many companies get edge of the positive aspects of deep groove ball bearings and minimize the housing dimensions of equipment, which qualified prospects to scaled-down and lighter assemblies. Deep groove ball bearings also match in a standard bearing housing, which tends to make it straightforward to substitute standard ball bearings with their superior counterparts.Common Utilizes of Deep Groove Ball BearingsEvery spinning element uses a ball bearing, and thanks to the positive aspects of deep groove ball bearings that we’ve talked about, they are the most common type of ball bearing.IndustrialDeep groove ball bearings are important elements of hefty machinery. They’re specifically beneficial in:GearboxesMotorsPumpsConstruction equipmentEngineering machineryWind turbinesAgricultural machineryMiningMachine toolsOffice equipmentMedical devicesFood processing machineryAerospaceResidentialThese ball bearings aren’t just restricted to industrial uses they are also frequent components of products in your home.

Types of Ball Bearings

There are many types of Ball Bearings available on the market, but which one is best for your application? Here, we will discuss the differences between Angular contact, Single-row, High-carbon steel, and Ceramic ball bearings. These types of bearings also feature races, or a groove in the center of each. These races are important in keeping the balls contained within the cylinder. They also provide a groove-baed pathway.


The ceramic ball used in ball bearings has many advantages. It is lightweight, operates at lower temperatures, has reduced skidding, and is resistant to electrolysis. The ball also exhibits longer fatigue life. All of these factors make the ceramic ball a good choice for many applications. But, how do you know if a ceramic ball bearing is right for your application? Read on to discover why ceramic ball bearings are a better choice than steel or stainless steel ones.
The ceramic balls are 40% more dense than steel. This means less centrifugal force is generated on the bearing, which suppresses heat generation. Because of this reduced friction, ceramic bearings are more efficient at transferring energy. Compared to steel bearings, ceramic balls have longer life spans. Nonetheless, these ceramic balls aren’t as strong as steel. Therefore, it is important to understand the limitations of the ceramic ball bearing before buying one.
The ceramic materials used for ball bearings are resistant to micro-welding. Metals undergo this process when imperfections in the surfaces interact. Eventually, this results in a brittle ball that reduces the life of a bearing. Unlike metals, ceramic materials have a stable behavior at high temperatures and exhibit less thermal expansion. This means that they can be used for applications where lubrication isn’t an option.
While steel balls can easily absorb contaminants and foreign particles, the ceramic ball is insensitive to this, and doesn’t require lubrication. This means they’re not susceptible to corrosion and other common problems. These are just a few reasons why ceramics are a better choice. This technology has a wide range of uses. It’s easy to see why it is so popular. If you’re looking for a new bearing for your application, be sure to contact an AST Applications Engineer. They can analyze your operating conditions and potential failure modes.

Angular contact

An Angular Contact Ball Bearing (also known as an angular-contact bearing) has an axial component that is generated when radial loads are applied. They are generally used in pairs, triplex sets, or quadruplex sets. These bearings are also available with Super Finished Raceways to reduce noise and improve lubricant distribution. Angular contact ball bearings have various design units, such as bore size, outer diameter, and outer ring width.
A single-row angular contact bearing has a radial contact angle that is equal to the angular distance between the two rings. Double-row angular bearings are designed for two-way thrust capability. These types of bearings can be purchased at Grainger and other online retailers. A typical angular contact bearing will last up to a million revolutions. They are often used in industrial angular contact bearings.
Single-row angular contact ball bearings feature a set contact angle. These bearings can support radial and axial loads, but they can’t withstand high speeds. Single-row angular contact ball bearings may also have one or two shoulders relieved. Thrust load is a pressure placed on the bearing when it is installed in an assembly, and it is used to create an angle between the races.
Angular contact ball bearings come in single and double-row configurations. They differ in the axial load they can carry and the type of lubrication they use. Angular contact ball bearings are ideal for high-speed applications and can accommodate both radial and axial loads. The type of contact and lubrication used in angular-contact ball bearings depends on the intended use for the bearing.

High-carbon steel

Carbon steel is a low-alloy and high-carbon steel used in bearings. This material provides superior strength and fatigue properties for ball and roller bearings. Its mechanical properties are ideal for applications where the temperature is less than 400 degrees Fahrenheit. High-carbon steel is also used to make bearing components for chrome steel bearings. These types of steels are softer than chrome steel but provide superior durability in applications where the material is exposed to severe conditions.
Hardened carbon steel balls with an AISI 1015 hardness index are used in a variety of automotive, commercial, and semi-precision applications. In addition to automotive applications, they are also used in slides, trolleys, and conveyors. AISI 1015 carbon steel balls are used in bearings. They can be purchased in a variety of weights and diameters. Carbon steel balls can also be purchased in nickel-plated or uncoated varieties for decorative purposes.
In order to determine whether a ball bearing is made of high-carbon steel, the material must be tested for its hardness. An ordinary pocket magnet will work well, but an ordinary rare earth magnet isn’t powerful enough to measure the hardness. If it attracts the magnet strongly, the metal is steel, while a weak magnet indicates a non-ferrous material. A hardness test requires a special microhardness test.
A lower-carbon steel is another option. Some miniature bearing manufacturers use a material with less carbon than AISI 440C. This material is also known as KS440 or X65Cr13. After being heat-treated, it develops smaller carbides, resulting in superior low-noise characteristics and the same corrosion-resistance as 440C. These materials are a less expensive alternative than chrome steel, but they are often less durable than chrome alloy steel.


Single-row angular contact ball bearings accommodate axial loads in one direction. These are normally adjusted against a second bearing. Unlike other ball bearings, they are non-separable and contain an upper and lower shoulder. Single-row ball bearings are made of Chromium Steel (GCr15) which is heat-treated to achieve high uniform hardness and excellent wear resistance. They are the most commonly used type of bearings in the world.
Because of the angular contact between the radial plane and the raceway, single-row ball bearings transmit radial forces from raceway to raceway. A higher a, the greater the axial load carrying capacity of the bearing. Single-row angular contact ball bearings are ideal for high axial loads. However, they have limited preload capabilities and must be installed in pairs. Hence, they are best used for applications where axial forces must be distributed.
Single-row ball bearings can be pre-lubricated and have steel shields. They are also available with rubber seals or snap rings on the outside edge. They are available with various retainers, including pressed steel cages, plastic shields, and rubber seals. A tapered bore is also available upon request. They are ideal for applications where space is limited. The 6200 series of bearings are especially well suited for electrical motors, dental hand tools, and optical encoders.
Single-row angular contact ball bearings are widely used for axial loads. The outer and inner rings have slightly larger radii than the balls. These bearings can accommodate high speeds and low torque. They can also be supplied with different grease levels. If grease is needed, you can choose a lubricant that has different characteristics depending on the application. They are easy to install and maintain. However, they are not recommended for adjacent mounting.


A plastic ball bearing is a highly versatile component that can be mounted in a variety of components, including wheels, pulleys and housings. The outer ring of a plastic bearing is usually the pulley profile. The inner ring can be made of a shaft or polymer. The integrated design of a plastic ball bearing helps to reduce assembly time and cost. Here are some of the benefits of this type of bearing:
First and foremost, plastic balls are lighter than metal balls. They also have less magnetic properties than steel balls, making them the best option for applications requiring low weight and noise. Glass balls are also lighter than stainless steel balls, making them the ideal metal-free choice. They are also very corrosion-resistant, which makes them a great choice for some applications. In addition to being lightweight, polymer ball bearings are also quiet. And because of their low weight, plastic ball bearings are ideal for applications that require fast speed.
Another advantage of plastic bearings is their ability to withstand high temperatures. This material is also abrasion and corrosion-resistant. It meets FDA and USDA acceptance requirements. Aside from its abrasion-resistant and corrosion-resistant properties, these plastics do not transfer heat. Aside from being extremely durable and flexible, most plastics are also self-lubricating. Common plastics include phenolics, acetals, nylon, and ultra high molecular weight polyethylene. Nonetheless, plastics have limitations, and these materials may be damaged by extreme temperatures or cold flow under heavy loads.
Other advantages of plastic ball bearings include their low density, high hardness and low friction coefficient, and ability to withstand heat and corrosion. Ceramics are also lightweight, non-conductive, and have superior resistance to friction. These products can withstand temperatures up to 1,800 degrees Fahrenheit. If you’re in the market for a plastic ball bearing, it’s important to choose the right type of material. And if you’re looking for a high-quality bearing, look no further.
