The thrust bearing is made of needle roller and cage assembly (or cylindrical roller and cage assembly) thrust washer . The needle rollers and the cylindrical rollers are hold and guided by the thrust cages. By using with any NRB thrust bearings washer , different bearing system will be formed. The bearing has a high load carrying capacity and high rigidity under a small space due to the high accuracy cylindrical rollers (needle rollers) has been used and th e length of the contact surfaces has been extended. Another advantage is, if the surfaces of the adjacent components (parts) can be appropriately used as the raceway surfaces, the washers can be left out, the design of the bearings will become compact.
As the exterior of the needle rollers and the cylindrical rollers are used as the contact surface, the edge stress can be reduced, the service life will be extended.
