Thrust needle roller bearings are composed of thrust retaining components with needle rollers or cylindrical rollers and corresponding thrust washers (as required). Needle rollers and cylindrical rollers are held and guided by the thrust cage. When the thrust cage assembly is used with different series of thrust pieces, it can provide many different combinations for the configuration of the bearing. Due to the selection of high-precision cylindrical rollers to increase the contact length, the bearing can obtain high load capacity and high rigidity in a small space. If the surface of adjacent parts is suitable as a raceway, the gasket can be omitted.
