Rolling bearing for use in e.g. rotary table, in spindle bearing unit, has outer ring whose outer side comprises axial portions with screw thread, where outer diameter of one portion is larger than outer diameter of other portion

摘要

The bearing (1) has rolling members (32) e.g. balls and rollers, radially guided between an outer ring (10) and an inner ring (20) in a raceway (30) around an axis (A). The outer ring comprises a front end (11) that is formed vertical to the axis, an outer side (12) and an inner side (14), where outer and inner sides are formed parallel to the axis, and the raceway is formed at the inner side of the outer ring. The outer side of the outer ring comprises axial portions (17, 19) with a screw thread (40), where outer diameter of one of the portions is larger than that of the other portion. The inner ring is designed as a threaded spindle, gear wheel, pinion, collet or a drivable-threaded nut.
