Introduction
The problem and the solution
An international steel producer suffered regular bearing failures on a continuous casting machine. Under heavy loads, wear and fatigue kept standard bearing life short: average life was 124 weeks and three failures had occurred. NSK recommended a durability trial with SWR Spherical Roller Bearings, made from specially developed bearing steel with far better wear and fatigue resistance.

Key Facts
Highlights
- Continuous casting machine — 20 segments
- Short bearing life due to wear and fatigue (approx. 124 weeks)
- Heavy operating conditions
- Longer bearing life and reduced maintenance costs requested
- Special Spherical Roller Bearings (SWR steel)
- Bearing life extended by 60%
Technical Features: SWR Spherical Roller Bearing
- Increased material strength for the outer ring
- Available sealed or unsealed
- Improved wear resistance — three times that of AISI 52100 bearing steel
- Minimised outer ring friction to extend bearing life
- Improved flaking life — five times that of AISI 52100
- SWR can replace a standard SRB without modifying axle boxes
