Method for adjusting the initial tension of a ball bearing, ball bearing unit with adjustable initial tension and rotary table and spindle with corresponding ball bearing unit

摘要

The pre-setting tension process is applied to a rolling bearing (3) between two components (1, 2). The inner ring (4) is fitted to one component (1), and the outer ring (5) to the other component (2). The bearing also contains several rolling bodies (6), i.e. balls or rollers. The temperature of at least one of the bearing rings can be regulated independently of that of the other.
