Urethane on Iron Wheels

UI WHEELS

RWM Urethane on Iron Wheels are liquid cast and chemically bonded to our machined cast iron cores. The core is a heavy-duty solid web design with an oversized hub, enabling it to be machine fitted for special bearings or a keyway. Careful attention is made during the bonding process to ensure that each urethane on iron wheels meet or exceed 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.

Applications & Features

Our urethane on iron caster wheels are liquid-cast and then chemically bonded to precision machined, cast-iron cores. This creates a durable, long-lasting construction similar to solid steel wheels. The design of our wheels means they are capable of resisting extreme hot or cold temperatures.

From our factory to your factory, our wheels are suited for use within industrial facilities, warehouses, food production facilities, and more. We manufacture urethane wheels with wheel diameters ranging from 3-1/2 to 20 inches and widths of 1-1/4 to 5 inches. We offer wheels with straight roller bearings, ball bearings, celcon bearings, or tapered roller bearings. Further, each wheel has an axle diameter of between 5/16 and 1-1/2 inches.

This gives our wheels an estimated carrying capacity of 400 to 9,000 lbs. They will also deliver quiet operation and won’t cause damage to flooring materials. Our wheels have superior wear properties and impact resistance for both indoor and outdoor applications.

At RWM, we make it possible to select the ideal option whether you choose to attach our wheels to diagnostic equipment or use them to move raw or finished goods throughout your facility. Our wheels are manufactured to precision specifications and will deliver reliable performance in the most challenging operational conditions.

We also offer numerous options that allow you to customize your wheels to meet your operational requirements. Available options include either black or red durometers, thread guards, wheel seals, and zerk fittings. Because the wheels are polyurethane, there is no need to add microbial resistance for use within food production facilities, packing plants, grocery stores, warehouses, etc.

We encourage you to contact RWM online or at 800-634-7704 for more information about the advantages our urethane on iron wheels offer. It’s our pleasure to help you select the ideal wheels for your operational environment and intended applications.

APPLICATIONS

Urethane on Iron Wheels also provide outstanding abrasion resistance and are resistant to most chemicals, grease, oils, and water. Our Premium PTMEG urethane wheels provide longer service life, better wear and tear characteristics, and reject floor debris. All wheels up to 8″ x 2-1/2″ wide are standard crown tread that reduces the amount of friction between the tread and the floor, improving the rollability and maneuverability of the wheel.
