Structure of cylindrical roller bearings

- Aug 17, 2017 -

The cylindrical rollers are in line with the raceway and the radial load capacity is large. It is suitable for heavy load and impact load, and also for high-speed rotation.


The raceway and rolling body of cylindrical roller bearing are in geometrical shape. After the improved design, the new structure design with higher bearing capacity, edge and roller end faces 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 edge of the baffle, and improves the performance of the bearing.


1. Outer ring without edge N0000 type and inner ring without retaining edge NU0000 type, cylindrical roller bearings such bearings can accept a larger radial load, the ultimate speed is high, not binding shaft or shell axial displacement, can not accept axial load.

2. The NJ0000 type and NF0000 type bearings with cylindrical roller bearings with flanges in the inner and outer rings can constrain axial displacement in one direction of the shaft or casing and accept a smaller unidirectional axial load. nu0000+hj0000-Type, nj0000+hj0000-type, NUP0000-type bearings can be axially displaced in two directions in the Axial clearance field of the imported bearings, and can accept a smaller biaxial axial load.
