Ball bearings are a sub-category of roller bearings. In ball bearings, rolling elements between a inner ring and an outer ring reduce frictional resistance, in contrast to lubrication in the case of plain bearings. The rings secure axles and shafts by absorbing radial and/or axial forces, depending on the structural form, while allowing the rotation of the shaft or components mounted on an axle (for example, a wheel). Rolling friction mostly occurs between the three main components of inner ring, outer ring and rolling element. Since the rolling elements in the inner and outer ring roll on hardened steel surfaces with optimised lubrication, the rolling friction of these bearings is relatively low. Deep-groove ball bearings Deep-groove ball bearings are particularly versatile. In addition to allowing the absorption of radial loads, they simultaneously enable the absorption of axial loads in both directions. They are of simple construction, durable in operation and maintenance and suitable for high to very high rotational speeds.
