What bearing is good for the rotating base of winch bucket?
Thrust ball.

Thrust ball bearing is recommended for the rotating base of winch bucket. This kind of bearing has high metal strength and good wear resistance. Made of rolling bearing steel, the surface hardness of the bearing after quenching can reach HRC 60-654.

The thrust ball bearing is designed to bear the thrust load at high speed, and consists of a washer-like ring with ball rolling raceway groove. Because the ring is cushion-shaped, thrust ball bearings are divided into two types: flat-bottomed cushion type and self-aligning spherical cushion type.
