Product Main

Specifications

 
-Description
Ball or rollers are used to prevent or minimise rubbing
-Friction
Rolling coefficient of friction with steel can be ~0.005 (adding resistance due to seals, packed grease, preload and misalignment can increase friction to as much as 0.125)
-Stiffness
Good, but some slack is usually present
-Speed
Moderate to high (often requires cooling)
-Life
Moderate to high (depends on lubrication, often requires maintenance)
-Cautions
Used for higher moment loads than plain bearings with lower friction
