Deep groove ball bearings are used in a particularly wide variety of applications. Consequently, they are available in many executions and sizes. For bearing arrangements, which have to operate at extreme temperatures in the range -150 to +350 °C, or which have to withstand very large temperature differences, e.g. in kiln trucks, furnaces or the conveyor systems of lacquering equipment, normal rolling bearings are unsuitable.
