Quick Reference Chart - Which wheel material should you use for your floor surface?
75 Series industrial casters feature the patented RWM Kingpinless™ design
to handle highly demanding applications. It's used in tough industries
such as boat & ship molding and building, automotive, aerospace, metal
fabrication, metal forging, heavy machinery and equipment, military
equipment, tractor pulled trailers, extreme duty platform trucks and
material handling carts, air cargo and ground support equipment, storage
tanks, gantries and heavy duty processing equipment.
Cast Iron Wheels are exceptionally long wearing, have tremendous resistance to shock, and are a good choice for high capacity loads in warehousing and manufacturing. Recommended for rough concrete, wood block, and littered floors.
Forged steel wheels provide maximum strength and durability—even under a load as heavy as 10,000 pounds. They are virtually indestructible within their capacity range. Use them in the toughest applications and on the most demanding floors, with the heaviest loads.
The Omega wheel can eliminate the need for spring casters. It achieves its high capacities and enhanced impact-absorbing ability with a patented web/spoke design. It flexes to cushion the load then rebounds to original shape. Resists tearing and chunking, and won't pick up metal chips.
Phenolic wheels (also called Durastan) provide excellent service even in wet and cold applications. They resist degradation, deterioration, and corrosion from oil, grease, and commonly used acids and solvents. Recommended for all types of floors except resilient tiles.
Also known as mold-on rubber, the rubber on iron wheel is floor-protective, provides long tread life, operates quietly, and is highly resilient. Suggest for almost all kinds of floors and for a variety of applications. It's well-suited for towline applications of the kind often found in freight terminals or warehouses.
Solid Urethane Wheels are designed primarily for applications involving high moisture. Injection-molded urethane, the urethane solid wheel provides extended service in moisture applications that normally destroy conventionally bonded wheels.
Capacities rival those of steel wheels. Careful attention is paid during the bonding process to assure that each wheel meets high performance standards. UI wheels are non-marking, and resistant to abrasion, chemicals, and oil. These wheels will typically outlast rubber wheels.
V-Groove wheels are machined with a 90 degree groove for operation on inverted angle iron track. They are used to control the flow of a load (into an oven, between machines, over long distances, or where "production line" sequences must be maintained.)

The patented Kingpinless™ raceway eliminates the number one cause of caster failure
RWM's patented offset precision-machined raceway exerts radial force evenly where there is full contact between the ball bearing and the raceway. RWM's unique design adds more mass at key points. This, plus more thorough heat treatment, provides additional strength and combats brinelling into the core material.
This means longer, better service life in demanding industrial applications
The inline positioning of many competitive raceways (as opposed to the offset positioning RWM uses) creates a direct hammering effect via the ball bearings, which are centered on the tangent of the two raceways, stressing, and eventually eroding the raceway. The inevitable result is a loose fit and progressive swivel failure. Even double raceways are subject to these hammering forces.
- No direct "hammering" forces on the intersections of the raceways for vastly reduced raceway wear
- Elimination of the "pull apart" forces of stress in the swivel section - a huge issue in towing applications
- Smoother swiveling action and better maneuverability
- Longer service life - maintenance is easier and less frequent
- Extra impact resistance and high radial force absorption
