Applications for Solid Urethane MU Wheels

These wheels can be used in hospitals and healthcare facilities where floor protection is a premium value. And, each Solid Urethane MU Wheel can be used in applications where the movement of heavy loads and continuous use can wear out and degrade standard poly wheels.

RWM’s Solid Urethane Wheels can be paired with the following series of rigs to create durable, long-lasting casters: 45, 46, 47, 48, 52, 58, 65, 68, 70, 75, 76.
