ABSTRACT:
The bearing lubricating system comprises a casing having a bore which defines a reservoir and a well sized to receive a sufficient volume of a suitable liquid lubricant. A return passage in the casing allows fluid flow from the well to the reservoir. A shaft extends through the reservoir and through the well. At least one bearing is situated in the bore between the reservoir and the well. A pumper element is mounted on the shaft for rotation therewith within the well. A pair of end seals seal off the opposite ends of the bore from the ambient.
