NTN Super Precision Bearings

Product Description

Precision Taper Roller Bearings are utilized within some CNC machining processes. They are found in small spindle designs that require heavy thrust load capabilities. They also can be found in other machining functions not related to the primary spindle itself. Their precision taper rollers are manufactured with tighter tolerances to maintain proper functionality.

The rigidity of the main spindle of a machine tool is associated with both bearing rigidity and shaft rigidity. Bearing rigidity is typically governed by the elastic deformation between the rolling elements and raceway surface under load. Usually, bearings are preloaded in order to increase the rigidity. Under same loading conditions, a roller bearing has a higher rigidity than a ball bearing of the same size.
