Superior Protection and Quiet Operation
The shield design was optimized using dynamic analysis modeling techniques.The design profile and plate thickness provides rigidity that helps quiet operation as well asretain grease and protect against intrusion of major contamination.
Rings and balls made of select material have superbly controlled accuracy such as roundness, contour,surface finish, and hardness to provide quieter operation, reduced vibration levels, and long life.Rivet-type pressed steel cages for strength and durability.High-performance grease for long life and low noise.
