What are Industrial Casters and Wheels?
Caster Concepts 57 Series
When searching for “Industrial casters and wheels” people sometimes land on “institutional casters and wheels.” These two caster types are definitely not the same. What are the differences? Capacity and construction!
Institutional Casters and Wheels are designed for applications under 250 lbs. Industrial Caster Wheels can handle tons. They are designed to meet high load applications and are very customizable, where Institutional Casters are not.
Institutional wheels may be injection molded plastic or urethane, or two-component wheels with a plastic core and the TPR (Thermo Plastic Rubber) tire. Composite resin may also be an option. These lighter-duty wheels are cold stamped metal with formed and welded legs on the outside surface only. Other characteristics of an institutional wheel include:
- Smaller diameter bearings that are captured in the swivel section at the time they riveted in place.
- The finish is usually clear zinc plating.
- Designed for light use and are not built for abusive applications
- Manufactured in high volume and are not customizable
Construction of Industrial Casters and Wheels
The construction of industrial casters and wheels consists of precision machined raceway swivel sections that are hardened to a predetermined hardness for a prolonged lifecycle.
- Medium-Duty Casters, capacities ranging from 250 to 1500 lbs.
- Heavy-Duty Casters, capacities ranging from 450 to 5000 lbs.
- Extra Heavy-Duty Casters, capacities ranging from 1600 to 20,000 lbs.
- Super Heavy-Duty Casters, range up to 50,000 lbs.
With Industrial Casters, heavy-duty construction goes into all aspects of the wheel. Swivel section material should be of high-quality material and heat treatable to 38-42 Rc. The legs are precision laser cut and formed to strengthen the caster. This is designed to add additional safety factors while alleviating failure points and minimizing welding.
Wheel cores are grey iron for a polyurethane tire. Additionally, the wheel maybe forged steel, nylon or composite resin. The swivel sections may be held in place by hardened ball bearings. The entire caster is assembled with high quality bearings to meet the load application and provide prolonged life cycle.
Industrial caster and wheel design and manufacturing lends itself to extensive customization to meet all the customer’s needs and specifications. If you would like more information on the proper caster for your specific application, chat with a Caster Concepts Representative or call 888.772.6790.
