9. Cylindrical roller bearings
The rollers of cylindrical roller bearings are usually guided by two ribs of a bearing ring. The cage roller and guide ring form an assembly that can be separated from another bearing ring and are separable bearings.
This kind of bearing is more convenient to install and disassemble, especially when the interference fit between the inner and outer rings, the shaft and the shell is required. This type of bearing is generally only used to bear radial loads. Only single-row bearings with ribs on both the inner and outer rings can bear small steady axial loads or large intermittent axial loads.

Main uses: large motors, machine tool spindles, axle boxes, diesel engine crankshafts, automobiles, transmission boxes with bearings, etc.

10. Four-point contact ball bearings
It can bear radial load and bidirectional axial load. A single bearing can replace the angular contact ball bearing of front combination or back combination. It is suitable for bearing pure axial load or synthetic load with large axial load component. This type of bearing can withstand any direction. One of the contact angles can be formed when there is an axial load, so the ferrule and the ball are always in contact with three points on both sides of any contact line.

Main uses: aircraft jet engines, gas turbines.

11. Thrust cylindrical roller bearings
It consists of a washer-shaped raceway ring (shaft ring, seat ring) and cylindrical roller and cage components. The cylindrical roller adopts convex surface processing, so the pressure between the roller and the raceway surface is evenly distributed, and it can withstand one-way axial load. It has large axial load capacity and strong axial rigidity.

Main uses: oil drilling rigs, iron and steel making machinery.
