Bearing strength and hardness also come into play, controlling the bearing’s susceptibility to abrasive wear, fatigue wear, and deformation. Harder bearings don’t scratch or deform as easily ...

After nine years of operation in the harsh, abrasive waters of Alaska’s Yukon River, ... Bearing System Sees No Wear After 20,000 Hours. Posted by Eric Haun ...

The reason for the softer bearing material is to further reduce wear. ... The adhesion and abrasive wear calculations share the same formula; however, it can vary by as much as +/-20%.
