Spindles designed for machine tool applications, such as milling, grinding and turning, require the bearings to be set in preload to meet speed, stiffness and accuracy requirements. More importantly, ...

Precision high-speed machining requires low-friction bearings that provide dynamic stability. Hybrid bearings with ceramic balls run faster and have higher stiffness than comparable all-steel bearings ...

This is the second of two reports. See Push/Pull Method for Preloading 2-TS Spindles: Why Preload? Preload force is very sensitive to the preload dimensional setting. The setting tolerance for a 2-TS ...
