3-1/2" Light-Medium Duty Swivel Plate Caster, 400 lb. Load Rating

Medium-duty standard plate casters mount to the bottom of carts, dollies, platform trucks, tool boxes, storage racks, and other industrial equipment that will be moved manually at moderate speeds. They are suitable for transporting loads along smooth, flat surfaces in areas where the casters won't encounter shock loading, such as shops, docks, warehouses, waste-disposal areas, manufacturing plants, and other industrial settings. These casters have zinc-plated steel frames. Swivel versions of these casters have double ball swivel bearings, which are quieter and allow the caster to swivel more smoothly than roller bearings.

Standard plate casters have kingpins that securely join the casters' mounting plates to their frames. They are used in nearly every industry and are the most common type of caster used for general purpose applications. The casters' mounting plates install onto the bottom of machinery, carts, or other equipment, and the casters allow the equipment to roll to reduce effort when moving or repositioning it. These casters are available in swivel and rigid versions. The swivel casters can rotate 360°, allowing equipment to change directions while rolling. The rigid casters roll in a straight line. Two rigid plate 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.
