💡 What makes polyurethane ideal for roller bearing applications?
Polyurethane combines flexibility with mechanical strength, providing high wear resistance, better load distribution, and shock absorption - making it ideal for dynamic systems subject to vibration, debris, or rolling impact.

Tough on the outside, smooth on the inside - engineered for durability and quiet rolling action.
