Thrust Roller Bearings
low friction coefficient
high speed and with self-aligning properties
can withstand a one-way axial

Characteristics of thrust roller bearing

Thrust roller bearings for main shaft axial load, radial joint load, but the radial load shall not exceed 55% of axial load.

Compared with other such bearings, this one has the advantage of low fiction, high speed and self-aligning properties.

 They can reduce the roller and raceway relative sliding at work, and the roller length,  diameter, and the number of multi-roller, high load capacity, usually in oil lubrication.
