ABSTRACT:
A pillow block and bearing assembly having a housing with a lubricating chamber with a bearing disposed therein and with axially aligned holes on opposite sides for receiving a shaft. The bearing is disposed in the chamber and includes inner and outer races and rolling elements therebetween, and an adapter for securing the bearing to the shaft engages the inner race for forming a press fit between the adapter, inner race and the shaft. A threaded means including a plurality of jack screws for moving the inner race axially on the tapered surface of the adapter adjusts the clearance between the inner and outer races and the rolling elements, and a hydraulic system is included in the adapter which communicates with the tapered surface and the inner surface of the inner race for releasing the adapter from the inner race and shaft when the threaded means has been loosened to permit axial movement between the inner race and the adapter. A window having a closure is preferably included in the side of the housing to permit observation of the bearing when an adjustment is being made with the jack screws.
