ABSTRACT:
A bearing assembly having coaxial inner and outer bearing races, a plurality of rolling elements which ride in respective raceways in the inner and outer races, and annular sealing discs interposed between the inner and outer races for defining annular lubricant containing chambers on opposed axial sides of the rolling elements. For facilitating circulation of lubricant between moving parts during use of the bearing, the outer bearing race is formed with lands which extend axially outwardly of the raceway with a slight radially inwardly directed taper of about 10.degree. to the bearing axis.
