Details

Cylindrical roller bearing characteristics: roller and raceway for line contact or repair line contact, radial bearing capacity is large, suitable for bearing heavy load and impact load; Small friction coefficient, suitable for high speed, limit speed close to deep groove ball bearings; N-type and NU type can move axially, can adapt to the change of the relative position between the shaft and the shell caused by thermal expansion or installation error, can be used as free end support; The processing requirements of the shaft or seat hole are higher. The relative deviation of the outer ring axis should be strictly controlled after the installation of the bearing to avoid the concentration of contact stress. The inner or outer ring can be separated for easy installation and disassembly.

Cylindrical roller and raceway line contact, radial load capacity is large. It is suitable for bearing heavy load and impact load as well as high speed rotation. Cylindrical roller bearing raceways and rollers are geometrically shaped. After the improved design, it has a higher bearing capacity. The new structure design of the flange and the roller end face not only improves the axial bearing capacity of the bearing, but also improves the lubrication condition of the contact area between the roller end face and the flange, and improves the service performance of the bearing.
