💡 Why is polyurethane ideal for coated bearing rollers?
Polyurethane offers higher load-bearing capacity than plastic and greater abrasion resistance than rubber. Its toughness and elasticity make it ideal for rolling elements that endure shock loads, vibrations, and surface wear in dynamic systems.

Reliable, resilient, and ready to roll - built for long-term performance in impact-prone environments.
