RWM is the original creator of the Kingpinless caster, and their 75 series caster definitely shows off their quality craftsmanship. Designed for the use of 3″ wide wheels, the 75 series is perfect for those heavy-duty applications up to 6,000lbs. With a deep blue powder coat, these casters will combat rust that would regularly see over time.
Urethane on Iron Wheels are liquid cast and chemically bonded to machined cast iron cores. The core is a heavy-duty solid web design with an oversized hub, enabling it to be machined to be fitted for special bearings or a keyway. Careful attention is made during the bonding process to ensure that each Urethane on Iron Wheel meets or exceeds RWM Casters high standards of performance. They will outlast rubber wheels. In addition, these wheels are non-marking to floors and provide a quieter ride than hard tread or steel wheels.
