Needle Roller Thrust Bearings

The Needle Roller Thrust Bearings is composed by thrust cage with needles and thrust washer.The needle can get maintains and guides from the thrust cage. When using together with different thrust bearing washer, it can offer many different combinations for bearings configuration.Due to the using of high accuracy cylindrical needle, the contact length has been longer, and the bearings can obtain high loading ability and high rigidity in very small space. Another advantage is that, if the surface of adjacent parts can be applied to raceway, we won't use the washer any more, and the design can be coherent. The needle and the cylindrical roller's cylindrical surface which are used on SATA's Needle Roller Thrust Bearing is modification surface, it can decrease the edge stress and improve the service life.
