Spindle bearing preload selection is key | Cutting Tool

Jun 01, 2011· A major challenge for designers of machine tool spindles with rolling element bearings is selecting and maintaining the preload in the spindle bearings. Preload means a radial load is applied to all the rolling elements, or balls, simultaneously. Spindle bearing preload is required for static accuracy. It keeps the rolling elements in contact with the spindle and …
