Ball-to-ball friction in bearings generates heat, limits the speed, and shortens the life of linear-motion guides. Ball-to-ball friction in bearings generates heat, limits the speed, and shortens ...

A load type factor f w accounts for vibrations, impacts, and inertial forces applied to the bearing. Smooth operation is assigned an fw value of 1 to 1.5; varied loading, 2 to 3. Linear bearing ...
