The outer ring of the cylindrical roller bearing is an important part of the bearing, and its main function is to provide an accurate and smooth rolling surface to support the operation of the roller in the bearing.
FTM cylindrical roller bearing outer rings can be made of customized materials and sizes, usually high-strength steel is selected to withstand higher radial loads.

The main characteristics and functions of cylindrical roller bearing outer ring
1. Provide raceway: The inner surface of the outer ring is precision machined to form a rolling track of the roller, ensuring stability and low friction during rolling.
2. Strong bearing capacity: cylindrical roller bearings mainly bear radial loads, and the outer ring needs to have high strength to cope with various workloads.
3. Detachable design: In some cylindrical roller bearing designs, the outer ring can be separated from the roller and the inner ring for easy installation and maintenance.
4. High precision and wear resistance: the raceway of the outer ring needs to have extremely high finish and hardness to extend the life of the bearing and maintain good operating accuracy.
Cylindrical roller bearings have a variety of configurations that affect the design of the outer ring. For example:
With flanges (e.g., NU, type NJ) : Some bearings have flanges on the outer ring to support limited axial loads in one or both directions.
No flanges (e.g., N, NN types) : In these cases, the outer ring is optimized for radial loads only and cannot support axial loads, which simplifies the design for radial-only applications.
The flexibility of this design enables cylindrical roller bearings to meet a wide range of industrial needs, from electric motors and gearboxes to mechanical and vehicle transmissions.
