Abstract
Abstract An angular contact bearing having a porous, permeable separator for lubricant circulation is disclosed. The separator includes a cylindrical surface which wipingly engages a cylindrical surface continuous with the raceway on the outer race. The lubricant circulation is from the cylindrical surface of the race through the porous separator to the balls; the balls in turn redistributing the lubricant back to the raceways and cylindrical surface.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
148 words
A lubricant recirculating ball bearing comprising in combination, an inner race having a deep groove raceway with uninterrupted shoulders, an outer race having a second raceway with a single shoulder adjacent one side of said raceway, said opposite side being unshouldered and having a cylindrical surface continuous with said second raceway substantially from its maximum diameter, a separator having a plurality of ball pockets and made from a permeable material, a complement of balls disposed in said pockets and rollably engaging said raceways, said separator including a cylindrical surface wipingly engaging said cylindrical surface on said outer race, and capillary means in said separator extending from said cylindrical surface to said pockets whereby lubricant wiped from said cylindrical surface on said outer race by said separator is delivered to said balls through said separator, said capillary means comprising the pore interstices of the permeable material in said cage.
