NSK Tough Steel Bearings for Contaminated Environments
Typical Bearing Failures
Most bearings don't reach their full L10 calculated life. NSK's Tough Steel family of bearings addresses the root causes of over 80 percent of bearing failures seen in their failure analysis labs: marginal lubrication and contamination.
Lab results have shown the following life increase versus standard materials.
› Up to 7X life in contamination
› Up to 5X life in marginal lubrication
› Up to 2X life in clean conditions
3% Fatigue Life
Mining Conveyor Pulley
Spherical Roller Bearing
Issue: Bearing failures due to contamination on head pulley were causing lost production and increased maintenance time.
Solution: NSK Tough Steel bearings extended the bearing life to over 6 years (from 18 months)
