A device comprising a sleeve-like outer member to be fixedly fitted in a bore of a housing, an annular inner member of L-shaped section having a flange secured to one end of the outer member, with an annular pressure chamber provided between the outer member and the inner member for receiving a pressure fluid, an outer ring of a roller bearing fitted in the outer member slidably only in an axial direction and having a cylindrical portion axially extending from its one end having a smaller inside diameter, the outer ring having its cylindrical portion slidably fitted in the pressure chamber, and sealing means for sealing clearances between the cylindrical portion and the outside and inside surfaces defining the pressure chamber and in sliding contact with the cylindrical portion, whereby the pressure of the fluid within the pressure chamber is axially applied directly to the outer ring to automatically adjust the preload on the bearing including the outer ring.
