Need to move something seriously heavy and do it smoothly? Check out this set of four industrial-grade casters from WEIBIDA. Each wheel can handle up to 800 lbs, so the whole set is rated for a massive 3200 lbs – perfect for workbenches, machinery, heavy carts, or industrial equipment. The wheels are 4 inches in diameter and feature a polyurethane tread chemically bonded to a lightweight aluminum core. This combo gives you easy rolling, is non-marking, and resists abrasion, oil, and chemicals (though avoid heavy wash-down environments). They won't rust like iron wheels, and the aluminum core looks sharp. The swivel plate has double ball raceways for smooth 360-degree rotation and low friction, and each caster includes a reliable brake to lock it in place. A maintenance-free, heavy-duty solution for your shop, garage, or facility.
