Load capacities shown throughout the catalog are to be used as guidelines and may differ depending on the application and type of performance desired. Trew capacities are based on intermittent use at speeds not greater than 3 mph. With treaded wheels, increasing the speed and/or duty cycle reduces the capacity. Many other factors can negatively influence the life of a wheel, such as obstacles, bearing lubrication and environmental conditions. Greater capacity (or other special requirements) can be achieved by modifying the tread type, hardness or thickness. Consult the factory for further information.
Wheels are made from nearly indestructible forged steel and as such are limited in capacity only by the type and size of the bearing used.
Poly on Iron/Steel
Our most versatile wheel is generally limit ed in capacity by the tread. Harder treads for higher capacities are available.
Rubber on Iron
Rubber treads are great for cushioning and quiet operation even on rough floors. However, rubber treads restrict capacity. Harder treads for higher capacity are available.
Heavily sectioned Class 30 iron designed to withstand heavy loads, and is capable of severe duty. However, cast iron is unsuitable for high impact/shock applications.
Drive wheel applications may have severe duty cycles and torque requirements which negatively affect the capacity of the wheel. Consult the factory for capacities per application.
