ABSTRACT:
This double row ball bearing has the bearing balls confined axially between confronting concave bearing surfaces on the outer and inner races. Each bearing surface has a compound arcuate curvature, with an outer arc extending laterally outward from the axial centerline of each bearing ball and having a minimum radius from the center of the ball which is offset radially outward from the latter's axial centerline, and with an inner arc intersecting the outer arc at the axial centerline of the ball and extending laterally inward therefrom and having a minimum radius from the center of the ball which is offset radially inward from the latter's axial centerline. Cages maintain the balls in each row spaced apart circumferentially.
