Heavy-Duty Caster Manufacturer

When you need heavy-duty casters for demanding industrial applications, turn to RWM Casters. We are proud to be the originator of Kingpinless™ casters, the most imitated casters in the industry today.

The Kingpinless design, which we invented in the 1970s, is far from our latest innovation. Several of our newer products have become industry standards by which all other copycats are measured.

For instance, our offset precision-machined raceway design maximizes load bearing capabilities and improves the long-term durability of our Kingpinless caster products. Our improved urethane wheel compounds are built to withstand unforgiving industrial applications, from those in the aerospace industry and tire manufacturing to automotive, construction, and equipment production applications.

We also offer medium-duty casters for carts and dollies, as well as heavy-duty casters in 4-inch, 5-inch, 6-inch, and 8-inch sizes. For more demanding applications, choose casters with wheel sizes of 14 inches or larger and capacities of up to 40,000 lbs. or more.

If you need a low-profile solution or stainless steel heavy-duty casters for your application, we have you covered. We also offer rigid, swivel, and locking casters in all sizes, allowing for custom wheel rotation solutions.

With over one million combinations of casters, wheels, and accessories to choose from, we have one of the most extensive product catalogs available. The wide range of casters we offer includes:

If you can’t find what you’re looking for, we would be happy to produce custom casters to meet your specific requirements.

Wheel Manufacturer

If you already have casters, but you need new wheels, explore our vast selection of durable products. We’re known for using high-quality polyurethane compounds, including polytetramethylene ether glycol (PTMEG), for our industry-leading line of caster wheels.

Our various product lines are designed to meet multiple manufacturing and industrial goals, including reduced push/pull forces, improved ergonomics, minimized noise, and enhanced shock absorption.

Towing and military applications have especially stringent testing and supporting documentation requirements, and our products meet them all.

Our wheel products include:

Parts & Accessories

Whether you need to modify your existing casters, replace a damaged part, or decrease rolling hazards in your facility, you’ll find what you’re looking for in our parts and accessories department. Every product we manufacture is made from durable, high-quality materials designed to complement your wheels and casters.

The parts and accessories we offer include:

  • Brake options for swivel and rigid casters
  • Swivel locks, including demountable swivel locks, passage swivel locks, heavy-duty threaded swivel locks, and foot-operated swivel locks
  • Floor locks to prevent portable equipment from shifting even when in a locked position
  • Turntables to allow heavy loads to rotate freely
  • Field installable foot guards to keep workers’ feet clear of caster wheels and improve safety
