RWM Casters invented the Kingpinless design, and you can count on our 75 Series caster when the going gets tough. We’ve designed this caster for challenging applications. The heavy-duty 75 Series comes with a wheel width up to 3 inches, well suited for high-capacity functions. These casters provide the ideal mounting system for a variety of wheels from our vast catalog.
Case hardening gives this caster the advantage over the induction- or through-hardening methods used by lesser manufacturers. Case hardening makes our 75 Series caster incredibly resilient and reliable for the long haul, offering superior performance with low risk of cracking. Our casters keep your carts, platform trucks, and tow lines moving under heavy loads at high speeds.
Caster Quality Is in the Details
Our patented Kingpinless™ single ball bearing design is precisely machined and raceway hardened to 53 Rockwell C minimum. With a standard notched raceway, the swivel section offers a 3-inch diameter raceway and half-inch ball bearings.
Choose wheels with a 1-inch roller bearing, rotating on a hardened and ground spanner bushing, or opt for three-fourths-inch tapered bearings rotating on the axle. All wheels come with lubricated fittings, ready to perform out of the box. The best brands in these demanding industries trust RWM Casters:
- Automotive assembly lines
- Heavy industry
- Aerospace manufacturing
- Aircraft maintenance
- Towing applications
- And more

For a rigid caster, change the “S” to “R” in the model number. For example, “47-UPB-0520-R.” To order rig only, omit the blue letters. For example, “47-0520-S.” For approximate weight of a rigid caster, deduct .7 pounds. Dimensions shown are nominal. If precise dimensions are required, please consult your RWM representative.
