Radial ball bearings 

Today the radial ball bearings are the most common type of bearings using balls as rolling bodies. These units consist of inner and outer rings, between which are located balls held by a bearing cage. The bearings of this type are designed for radial and axial loads and can be used with shafts rotating with a high frequency. They are non-detachable and have a very low ability to self-setting. The manufacturers produce radial ball bearings in various designs, including those with seals.
