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.
A pillow block and bearing assembly comprising a housing having a lubrication chamber therein and opposed openings for receiving a shaft, a bearing disposed in said chamber and having inner and outer races and rolling elements therebetween, an adapter extending axially through said housing openings and having a longitudinal split therethrough and a tapered annular surface for engaging the inner surface of said inner race, a screw means disposed on one end of said adapter engaging said inner race for urging the tapered surface of said adapter into engagement with said inner race, means defining hydraulic fluid passages in said adapter for releasing said adapter from said inner race when said screw means has been loosened, and sealing means at each of said openings in said housing between the housing and adapter for sealing lubricant in said chamber.
In a pillow block and bearing assembly having an inner race, a longitudinally split adapter having a large and a small end and having an annular tapered external surface therebetween for engaging the inner surface of the bearing race, an annular threaded portion on said small end of the adapter a screw means disposed on said threaded portion, an annular sealing part on the periphery of said screw means, an annular sealing part on the periphery of said large end of said adapter, means defining a fluid passage extending longitudinally from a point near one end of the adapter for hydraulic fluid, and a passage connecting said passage with said tapered surface.
