Cylinder roller bearing

Cylinder roller bearing is a kind of separable bearing outer ring, its roller is linear contact, small friction

coefficient, extreme high speed.

Bearing installation is convenient for dismantling, normal only bear radial load, only with internal and

external are raised edge, single cylinder roller bearing can withstand small quantitative axial load or larger

gap axial load.

Detailed info of cylindrical roller bearing

1. Cylindrical roller bearing

The roller and raceway surface of cylindrical roller bearing is line contact,so the bearing has high

carrying radial load capacity,applicable to carrying heavy load and shock load.

Besides,owing to its structure,it\'s easy to high accuracy processing,applicable to highrate rotary.

Inner ring and orter ring are separable,convenient for mounting and dismounting.

2. Single row cylindrical roller bearing

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.

3. Double row cylindrical roller bearing

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.
