RWM Casters Company Whisper Wheels HD Urethane on Iron Wheel UW Wheels

The Whisper Wheel, a Heavy Duty Urethane on Iron Wheel, is a unique design in which one inch of urethane is molded to a specially machined cast iron core. The core is uniquely machined and the urethane is mechanically and chemically bonded to the core. This unique design provides you with a wheel that is longer wearing than standard urethane wheel designs, resists lateral delamination of the tread and reduces noise and provides a quiet ride. Our Premium PTMEG urethane used in the design of the Whisper Wheel provides longer service life, better wear and tear characteristics and rejects floor debris.
