Cummins®

The Cummins 3393621 Ball Bearing is a specialized component designed for use in commercial truck operations. Its purpose is to facilitate smooth and efficient rotational movement within various truck components, thereby contributing to the overall performance and reliability of the vehicle. The significance of this bearing lies in its ability to reduce friction and wear, which are important factors in the longevity and efficiency of truck operations ¹.

Basic Concepts of Ball Bearings

Ball bearings are mechanical components that consist of an inner ring, an outer ring, and a series of balls that are held in place by a cage. They function by allowing rotational movement with minimal friction between the two rings. This is achieved as the balls roll within the races, distributing the load evenly and reducing the stress on the components. Ball bearings are widely used in various mechanical systems due to their efficiency in handling both radial and axial loads ².
