Typically, Slewing Bearings are big-dimensions rolling bearings that can accommodate axial,radial and moment hundreds performing both singly or in mixture and in any path. They can execute the two slewing (oscillating) movements as well as rotational actions.

Basically, a slewing bearing is composed of an inner ring (a), an outer ring (b) and rolling factors − balls (c) or cylindrical rollers − that are divided by polyamide spacers (d). The rings, 1 of which typically incorporates a gear (e), are offered with holes (f) to accommodate attachment bolts. The holes may be threaded. Typically, only the raceways in the rings (h) are hardened and precision-floor. Integral seals (g) made of acrylonitrile-butadiene rubber (NBR) maintain the CZPT in, and contaminants out of the bearing. Slewing bearings are re-lubricated Slewing bearings via grease fittings (i) to decrease upkeep and working fees.
