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 cartsplatform trucks, and tow lines moving under heavy loads at high speeds.
