In mechanical terms, a bearing is a machine element that facilitates smooth and controlled motion between two or more moving parts. It is designed to reduce friction and support the load generated by the moving components, allowing them to move relative to each other with minimal resistance. Bearings are crucial in a wide range of machinery and equipment, providing support for rotational, linear, and oscillating motion.

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:
