NTN Ball Bearings - Grainger Industrial Supp
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.

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.
