Conductive Rubber Tread on Plastic Core Wheel, 4" Wheel Dia., 300 lb. Load Rating

These wheels have a conductive rubber tread that disperses static electricity by letting it flow to the ground. They also have a plastic core that is lighter and more corrosion-resistant than a metal core. Sometimes called conductive casters, these casters are used on carts that will be carrying electronic components and other sensitive equipment. The casters help dissipate static electricity buildup that can damage the equipment on the carts, injure people who touch the carts, or cause sparks that can ignite flammable vapors near the carts. Conductive rubber tread on plastic core wheels are used in medical settings, laboratories, computer rooms, cleanrooms, electronics manufacturing facilities, and other areas where static electricity buildup is a concern.

Wheels with rubber treads are suitable for most types of flooring and provide more floor protection than wheels with metal treads. They are available in a range of hardnesses. In general, soft rubber treads offer more cushioning and better floor protection than hard rubber treads, and hard rubber treads provide more weight capacity, better abrasion resistance, and easier rolling than soft rubber treads. Rubber tread standard wheels are used for replacing the existing wheels on carts, racks, and similar equipment.
