Deep groove ball bearing (DGBB) is the most typical rolling bearing. Its structure is simple and it is convenient and thus widely used. It is an inseparable type. Both the inner and outer raceways are arched. It can bear both the radial and axial loads. The friction factor is small and the speed limit is high. So it fits well on occasions with high speed and low noise/vibrations. This bearing can be widely used on vehicles, machine tools, motors, instrumentation, construction machinery， railway vehicles, agricultural machinery and all kinds of professional machinery.

Four point contact ball bearing (FPCBB) is a separable bearing type. It has double IR or OR, with a contact angle *5°. Each ball contacts the rings on 4 points. In this way, the bearing can bear radial loads, axial loads on both directions or combined radial and axial loads. This kind of bearing can limit the displacement of the shaft or housing on both sides within the axial clearance of the bearing. It can be divided into QJ type and QJF type as per the design. It is featured with high speed, and it can bear loads on both directions. FPCBB has both the functions of the single-row and double-row angular contact ball bearing. 
This bearing is used on rolling mill, main shaft on machine tools, gas pressure machine, printing
and so on.

Thrust ball bearing (TBB) can be divided into single-direction and double-direction. Single-direction TBB can bear the load from just one direction, while the double-direction TBB can bear the load from both directions. Neither of them can bear the radial load. There must be an axial pre-load during the bearing running. This bearing is mainly used on vehicle turning system, main shaft on machine tool, rubber machinery and so on.
