NTA Inch Thrust Needle Roller Bearing

NTA Inch Thrust Needle Roller Bearing(Thrust Roller Bearing, Thrust Needle Bearing) mainly carry axial force, assemble with thrust cage, Needle Roller or roller and washer. Thrust bearing can be used separately and can be used with washer also. It has high load and high rigidness. Widely used in automobile, metallurgical machinery, textile machine, electric motor, transmission shaft and gear box, etc.

Main characteristic

1. carry one way axial load

2. low height of axial cross section, save space in assemble

3. High precision in axial
