Structural characteristics of cylindrical roller bearings

The structure of cylindrical roller bearings is divided into the following two categories

1. The outer ring has no ribs N0000 type and the inner ring has no ribs NU0000 type. Cylindrical roller bearings can accept larger radial loads, have high limit speeds, do not restrict the axial displacement of the shaft or housing, and cannot accept axial Load.

2. NJ0000 and NF0000 cylindrical roller bearings with ribs on the inner and outer rings can restrain the axial displacement of the shaft or housing in one direction, and can accept small unidirectional axial loads. NU0000+HJ0000, NJ0000+HJ0000, NUP0000 type bearings can restrain the axial displacement of the shaft or the shell in the axial clearance area of the imported bearing, and can accept small bidirectional axial loads.
