Abstract
Apparatus is provided for mounting a rotatable member such as a machine tool spindle within a bore provided in a housing, the rotatable member being journaled in a number of bearings. A bearing support sleeve disposed within the bore to support the bearings includes a first portion tightly fitted in the bore, a second portion slip-fitted in the bore and positioned to apply a pre-load force to the bearings, and a yieldable member joining the first and second portions. The pressure in a fluid system associated with the yieldable member is increased to deform the yieldable member and to thereby urge the second portion axially to apply a pre-load force to the bearings which corresponds to the pressure increase.
