RWM Medium Duty, Swivel Easy-Turn Kingpinless Plate Caster; 2460 lb. Load Rating, 6" Wheel Dia., Gray Core

Easy-turn extra-heavy-duty kingpinless plate casters each have two wheels mounted on a single axle. This reduces the friction between the floor and the wheels (also known as scrubbing) and allows the casters to swivel more easily than single-wheel plate casters. They have thick steel frames, large-diameter ball bearings, and large-diameter hardened bearing raceways that distribute loads evenly across the caster, which allows them to bear heavier loads, tolerate more frequent use, and withstand more impact than medium-duty or heavy-duty casters. These casters are suitable for use on carts, trailers, heavy machinery, storage tanks, and other equipment used in towing and pushing applications in heavy manufacturing, automotive and aerospace assembly, metal fabrication, boatbuilding, and similar industrial operations.

Impact-resistant kingpinless plate casters do not use a kingpin to hold the caster together. They distribute weight more evenly, roll more smoothly, tolerate higher speeds, and have better resistance to impacts and shock forces than standard plate casters that are held together with kingpins. The casters' mounting plate attaches to the bottom of machinery, carts, or other equipment. The caseters allow the equipment to roll, which reduces effort when moving or repositioning it. Kingpinless plate casters are available in swivel and rigid versions. Swivel casters can rotate 360°, allowing equipment to change directions while rolling. Rigid casters roll in a straight line. Two rigid casters will often be paired with two swivel casters to allow the equipment to both maneuver around curves and obstacles and maintain a straight course while rolling. Kingpinless plate casters are used in aggressive applications where they will encounter shock forces and heavy loads or be moving at high speeds.
