Cylindrical roller bearings are rolling bearings consisting of a disc-shaped roller and a cylinder, and are mainly used to bear radial loads, but can also bear axial loads and torsional loads. The rollers of cylindrical roller bearings are arranged in parallel, and spacers are installed between the rollers, which can effectively avoid the inclination of the rollers or the mutual friction between the rollers, and reduce the increase of the rotational torque.
Cylindrical roller bearing features
1. It has excellent radial load characteristics, strong bearing capacity, and is suitable for bearing heavy loads.
2. It can withstand large axial impact load and keep parallel to the shaft.
3. It has excellent radial rigidity, and there will be no excessive displacement at the contact with the shaft.

4. It can also bear a certain axial load when the temperature is high, and has self-lubricating ability.
5. The friction coefficient is small, suitable for high-speed rotation, and the limit speed is close to that of deep groove ball bearings.
6. Cylindrical roller bearings are separable bearings, the inner ring or outer ring can be separated for easy installation and disassembly.
Applications of Cylindrical Roller Bearings
Cylindrical roller bearings are suitable for occasions requiring high speed, high load and high precision. They are widely used in large motors, machine tool spindles, axle boxes, diesel engine crankshafts, automobiles, etc.
