About Casters and Wheels

Extra-High-Capacity Colossus Casters with Polyurethane Wheels






Move your heaviest loads with the largest casters we offer. Their forged steel construction holds up in demanding applications. Wheels have a hard metal core for strength with a polyurethane tread that combines the abrasion resistance of plastic with the shock-absorbing qualities of rubber. Use them on smooth or rough floors and in areas with debris.
Impact-resistant tapered roller bearings in the wheel and the swivel withstand both downward and side force.
Dual-wheel casters provide better load distribution and easier turning than single-wheel casters.

Extra-High-Capacity Stronghart Casters with Polyurethane Wheels






Forged steel construction holds up in demanding applications. Wheels have a hard metal core for strength with a polyurethane tread that combines the abrasion resistance of plastic with the shock-absorbing qualities of rubber. Use them on smooth or rough floors and in areas with debris.
Roller wheel bearings provide smooth rolling. Tapered roller wheel bearings withstand both downward and side force.
Swivel casters have double-ball bearings for the smoothest swiveling. Casters with wheel brake apply pressure to the wheel to stop movement with a press of the foot pedal. Casters with swivel lock prevent the caster from swiveling with a twist of the ring.Forged steel construction holds up in demanding applications.
