Ball bearings, or deep-groove bearings, extend the working life of equipment by enabling wheels, pulleys, and other rotating parts to reduce friction and move smoothly. Ball bearings have a series of round balls encased in a housing and support high axial or low-to-moderate radial loads. Axial (thrust) bearings support loads parallel to the axis, such as those exerted by a table supporting a weight. Radial bearings support loads where the force of the load is perpendicular to the shaft, such as those exerted by a rotating wheel. Angular (linear) bearings have two rows of balls set at an angle to one another for use with radial and axial loads. Ball screw support bearings are high-precision angular bearings used to support high loads and restrict axial movement for precise positioning for machining and other ball screw applications. Agricultural disc bearings are used in high-impact industrial applications where the bearing is exposed to high levels of dirt or other contaminants.

Bearings reduce friction between two objects, which allows moving parts to run smoother. Bearings are divided into two main categories: thrust bearings and radial bearings. Thrust bearings support axial loads, which are parallel to the axis of rotation, while radial bearings support turning shafts perpendicular to the axis of rotation. Depending on the application, there is a wide range of bearings to choose from. Common types of bearings include ball bearings, split bearings, and roller bearings. Bearings are also available in mounted, unmounted, and flange styles. Ball bearings are the most common type of bearing and are used in applications requiring support of smaller loads. Split bearings are ideal for hard-to-reach places and quick installation while roller bearings are suitable for heavier loads. Roller bearings are generally available in three styles: tapered roller bearings, cylindrical roller bearings, and spherical roller bearings. Key elements to consider when selecting bearings are outer diameter and the shaft diameter the bearing will fit.
