Needle Roller Thrust Bearings

Needle Roller Thrust Bearings are fitted with a form-stable cage to consistently retain and control a large number of needle rollers. Very small diameter deviance of the rollers within one assembly allows these bearings to house heavy axial loads and shock loads. The ends of these rollers are released somewhat to modify the line contact between rollers and the raceways. This invariably avoids stress peaks at roller ends to provide durability. They provide an enhanced degree of stiffness in limited axial space. Applications where faces of adjacent machine components are built to serve as raceways, this needle roller thrust bearings take up no more space as compared to traditional a thrust washer.
