General structure of cylindrical roller bearings

1. The outer ring without flange N0000 type and the inner ring without flange NU0000 type, cylindrical roller bearings can accept large radial loads, high limit speed, do not bind the axial displacement of the shaft or shell, and cannot accept axial loads.
2. Cylindrical roller bearings with flanges in the inner and outer rings NJ0000 and NF0000 can bind the axial displacement in one direction of the shaft or shell, and can accept small unidirectional axial loads. NU0000+HJ0000, NJ0000+HJ0000 and NUP0000 bearings can bind the axial displacement in both directions of the shaft or shell in the axial clearance field of imported bearings, and can accept small axial loads in both directions
