SY America 5x2 Inch Heavy Duty Casters | Polyurethane On Aluminum Wheels, 1100 LB Capacity Each, Top Plate 4x4.5 Inches, Non-Marking

Need to move something seriously heavy? These SY America casters are built for the job. Each wheel is 5 inches in diameter and 2 inches wide, with a polyurethane tread bonded to an aluminum core. That means they're strong (each caster can handle up to 1100 pounds!), but also lighter and quieter than all-steel wheels, and they won't mark up your floors. The top plate measures 4 by 4.5 inches for easy mounting, and the overall height is about 6.5 inches. They have a ¾-inch roller bearing and a ½-inch spanner bushing with a grease fitting for smooth rolling. The yoke is galvanized steel for extra strength and corrosion resistance. Perfect for industrial equipment, heavy carts, workbenches, or any project where you need reliable, heavy-duty mobility. A set of 4 can move up to 4400 pounds!
