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, ...

Preloading bearings is essential for achieving optimal performance, as it ensures minimal friction and proper contact between components. Wave springs play a key role in reducing play, minimizing wear ...

We’ve got to admit that watching [Ben Krasnow]’s new video on air bearings is tough. We found our eyes constantly checking the spherical air bearing in the foreground, which for the first eight ...

Bearing deflection or yield is elastic deformation occurring between balls and raceways because of external loads. Deflection increases nonlinearly as external load increases. To increase bearing ...
