The purpose of the deep groove type of ball races in a ball bearing is to provide a specific design that enables the bearing to effectively support radial and axial loads, reduce friction, and facilitate smooth and efficient rotation. The deep groove design of the ball races serves several key purposes, contributing to the overall functionality and performance of the ball bearing:

   - Ball Bearing: Ball bearings, including deep groove ball bearings, utilize spherical balls as rolling elements that move between inner and outer raceways. They are primarily designed to support radial loads, with some designs capable of handling limited axial loads. Ball bearings are commonly used in applications where smooth and efficient rotation is required, such as in electric motors, pumps, and gearboxes.
