Thrust Ball Bearing KOYO 51206 Bearing 30×52×16mm Used In Crane Hooks
Single Direction Thrust Ball Bearing KOYO 51206 Bearing is one kind of ball bearings design. Its dimension is 30×52×16mm,weight is 0.13kg , the material are adopt high quality chrome steel, thrust ball bearing consist of shaft washer , housing washer , rolling elements and cage assembly. so we can see that this kind of bearing have different with deep groove ball bearings and self-aligning ball bearings , angular contact ball bearings . they are all mainly carry axial loads .
Balls of Thrust ball bearing KOYO 51206 Bearing are arranged between a set of washers (a shaft washer and housing washer) and the contact angle is 90°. Axial loads can be supported in only one direction and radial loads cannot be supported. These bearings are unsuitable for high speed operation . they have pressed steel cage and brass cage .

Thrust Ball Bearing can be much more design
Single Direction Thrust Ball Bearings
Double Direction Thrust Ball Bearings
Four contact Ball Bearings
Thrust ball bearings and four-point contact ball bearings are suitable for light or normal loads that are purely axial. Single direction thrust ball bearings can accommodate axial loads in one direction only . For axial loads acting in either direction , double direction thrust ball bearings are needed.
