We will be discussing ball bearings. This is just one of many types.

Double Row Deep Groove Ball Bearing

The Double Row Deep Groove Ball Bearing embodies the same principle of design as the single row bearing. However, the grooves for the two rows of balls are so positioned that the load lines through the balls have an outwardly converging contact angle. This bearing has a lower axial displacement than occurs in the single row design…substantial thrust capacity in either direction…and high radial capacity due to the two rows of balls.
