Description: It features a smooth surface, anti-corrosion and nice load carrying capacity, which is suitable for many applications. The needle roller bearing has a uniform hardness, low friction, low noise, which will speed up work and production efficiency. Needle Roller Thrust Bearings provide a high degree of stiffness within a minimum axial space. It has a smaller cross-section than a standard thrust bearing for use in restricted spaces. These bearings to accommodate heavy axial loads and peak loads due to small diameter deviation of the rollers within one assembly. Made of hardened spring steel, both faces of the washers are polished and can be used as raceways. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.
