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:

Tapered roller bearings are used in a wide range of applications due to their ability to support both radial and axial loads. Some common uses of taper roller bearings include:
