Preloading of Combined Angular Contact Ball Bearings-72
As a general rule, an extra light or light preload should be selected for grinding spindles and the main shafts of machining centers, while a medium preload should be used for the main shafts of lathes, which require rigidity. When speeds result in a value of d pw X n (d m n value) higher than 500,000, the preload should be very carefully studied and selected.
