ABSTRACT:
A device comprising an outer ring formed with a cylindrical portion extending from its small diameter end at the radially inward portion thereof, a case having an inside surface including a large diameter cylindrical surface and a small diameter cylindrical surface to provide a stepped portion in the inside surface, the outer ring being received in the case in sliding contact with the large diameter cylindrical surface and the small diameter cylindrical surface, means for rendering the outer ring slidable only axially within the case, means for sealing the large diameter and small diameter sliding contact surfaces of the case and of the outer ring, and a pressure chamber defined by and provided between stepped portion end surfaces axially facing each other and formed between the large diameter and small diameter sliding contact surfaces of the case and of the outer ring to receive a pressure fluid. The pressure of the fluid within the chamber axially acts directly on the stepped portion end face of the outer ring to thereby automatically adjust the preload on the bearing.
