The challenge that machine tool builders face when designing spindles is selecting bearings with the optimal balance of speed, load-carrying capacity, stiffness, and precision – the four factors of ...

Phenolic or fiber-resin cages are designed for spindle bearings and machine tool applications. These bearing retainers or bearings cages are relatively lightweight and can withstand high speeds and ...

Angular contact bearings have one ring shoulder partially or totally removed. This allows a larger ball complement than found in comparable deep groove bearings, hence a greater load capacity. Speed ...

Air bearing spindles from Precitech are manufactured on-site. The shafts are ground using an extremely precise CNC grinding system, which allows us to grind the shaft OD and the thrust journal faces ...
