SKF Bearings - Bearing Parts & Supplies - Grainger .
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.
