Ball bearings are used with applications that have high axial loads and low-to-moderate radial loads. Mounted bearings (bearing units) have a bearing inside a housing unit to ensure a secure fit and mount. Sleeve and clip bearings support high loads, have no moving parts, and require lubricant to allow the shaft to turn smoothly.

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.
