It consists of a shaft ring, a seat ring and a cylindrical thrust roller cage assembly, which canbe installed separately. It has a small axial section, can bear the axial force in one direction, and has the characteristics of high bearing capacity and high rigidity.

It has self centering performance and is composed of a shaft ring, a seat ring, and a set of asymmetric spherical rollers with a cage. The shaft ring and the cage roller assembly form a whole and can be separated from the seat ring, making installation more convenient.

Equipped with an independent thrust needle roller assembly and two thrust washers, it can provide very high axial load and stiffness in a very small axial space. The thrust needle roller assembly can be used together with adjacent machine components to replace the raceway, saving more axial space.
