When the two split rings are assembled, the ball pockets of one split ring are aligned with the ball pockets of the ...	06/16/1992
5044783	Pocket surface for separator for ball bearings A separator or cage for ball bearings has a plurality of pockets. Each pocket has an internal pocket surface toward the ball. At each half of the pitch circle of the pocket around the ball there are two approximately cylindrical first surface sections whi...	09/03/1991
4958946	Separation for ball bearings A separator or cage for a row of ball bearings designed to reduce friction on the balls. The pocket surfaces in the separator have recesses in the region of the axial "poles" of the balls which prevents contact between the balls and the separator pocket w...	09/25/1990
4902145	Ball separator for bearing assembly A separator for the balls of a ball bearing assembly, especially of the land riding variety which is constructed of two like parts joined together by ultrasonic welding. The separator is provided with generally cylindrical ball receiving pockets. Skis are...	02/20/1990
4886379	Cage for ball bearings A cage for a ball bearing comprised of two generally ridge-shaped ring parts, the respective axially projecting ridges of which are cooperatively placed to define respective pockets for the balls. The plane of separation between the two ring parts is shif...	12/12/1989
4732496	Two-piece ball cage for bearing assembly A ball bearing cage consisting of a pair of annular cage portions having opposing surface portions defining circumferentially spaced radial bores for receiving balls. One of the cage portions is formed with a radially outwardly projecting circumferential ...	03/22/1988
4626113	Cage for a radial ball bearing A cage for a radial ball bearing comprises an annular body of resilient material formed with pockets for reception of the balls as a snap fit and prongs for guiding the balls into the pockets when the annular body is fitted in the bearing from a side ther...	12/02/1986
