The challenge that machine tool builders face when designing spindles for milling machines and lathes is selecting bearings with the optimal balance of speed, load-carrying capacity, stiffness, and ...

This is the third and final report in a series, Selecting, Configuring and Lubricating Tapered Roller Bearings for High-Speed Machine Tool Spindles. The first installment is Selecting Tapered Roller ...

Roller screws convert rotary motion into linear motion just like acme and ballscrews. Comparably sized roller screws, however, have better efficiency than acme screws and can carry larger loads than ...

Most linear bearings incorporate ball bearings (usually of metal) to reduce friction between moving parts. Of these designs, most bushings, ball splines, linear guides and slides recirculate balls. As ...
