The thrust bearing is composed of a thrust cage assembly with a needle roller or a cylindrical roller or a ball and a thrust washer. Needle rollers and cylindrical rollers are held and guided by thrust cages. When used with different series of DF thrust bearing washers, many different combinations of bearing arrangements are available.
Because the selection of high-precision cylindrical rollers (needle needles) increases the contact length, this bearing can obtain high load capacity and high rigidity in a small space. Another advantage is that if the surface of the adjacent part is suitable for the raceway surface, the gasket can be omitted, which can make the design compact. The modified surface can reduce edge stress and improve service life.
