This thrust roller bearing composed of a thrust roller and cage assembly, wherein needle rollers or cylindrical rollers are configured radially in the cage, and a bearing ring of disc form is intended to support one-directional axial load. In mounting, it is possible to use a shaft or a housing as the direct raceway surface without using the bearing Thrust Roller Bearings ring, whereby design of a low height and lightweight compact construction is enabled. This type of thrust roller bearing results in slipping on raceway surface because theoretically it can't roll perfectly, but in most cases it is practically trouble-free and can rotates at comparatively high speed.
