NO 2. Feature: Cylindrical roller bearing

Single row cylindrical roller bearing feature:

Tape NU and type N allow shaft moving in axial direction within limits,applicable to use as free end.

Type NJ and type NF can carry certain extent one-way axial load.Type NUP and type NH can carry certain extent both-way axial load.

Main dimension of type E cylindrical roller bearing coordinate with standard, and through modifying interior specification to increase nominal load.

Double row cylindrical roller bearing feature:

Double row cylindrical roller bearing have cylindrical hole and tapered hole type,tapered bore bearing can get needed internal clearance by self-aligning the depth of thrusting in.

Besides,there are bearing whose outer ring with oil hole and oil tank,it's nominal type code has a post position assistant code "W".

The type bearing has strong fixity resisting reversal load,mainly applicable to chief shaft of machine tool,etc.

NO 3. Types of Cylindrical roller bearing

  NU   series cylindrical roller bearing  design The outer ring of bearings of the NU design has two integral flanges and the inner ring is without flanges. Axial displacement of the shaft with respect to the housing can be accommodated in both directions within the bearing itself.

  NJ   series cylindrical roller bearing  design The outer ring has two integral flanges and the inner ring one integral flange. The bearings are therefore suitable for the axial location of a shaft in one direction.

  NF  series cylindrical roller bearing  design The outer ring has one integral flange and the inner ring two integral flanges.

  NP   series cylindrical roller bearing  design  The outer ring has one integral flange and one non-integral flange in the form of a loose flange ring and the inner ring two integral flanges.

  NUP   series cylindrical roller bearing  design The outer ring has two integral flanges and the inner ring one integral flange and one non-integral flange in the form of a loose flange ring. The bearings can be used as locating bearings, i.e. they can provide axial location for a shaft in both directions.

  RN   series cylindrical roller bearing  design No outer ring and the inner ring two integral flanges.
