Cylindrical Roller Bearing Features

1. Roller and raceway for line contact or repair line contact, radial bearing capacity is large, suitable for bearing heavy loads and impact loads.

2. Small friction coefficient, suitable for high speed, limit speed close to deep groove ball bearings.

3. N type and nu type can move axially, can adapt to the change of the relative position of the shaft and the housing caused by thermal expansion or installation error, and can be used as a free end support.

4. The processing requirements for the shaft or seat hole are higher, and the relative deviation of the outer ring axis after the bearing installation should be strictly controlled to avoid contact stress concentration.

5. The inner ring or outer ring can be separated for easy installation and disassembly.
