75 Series Casters

HEAVY-DUTY KINGPINLESS CASTERS

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.

When you need to move heavy parts, trust RWM Casters for your Kingpinless caster needs. Our 75 Series casters are ready for the heaviest-duty applications! Contact us at 800-634-7704 to order today.

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.

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” diameter raceway and ½-inch ball bearings.

Choose wheels with a 1-inch roller bearing, rotating on a hardened and ground spanner bushing, or opt for ¾-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:
