Medium Heavy Duty Casters | to 1,500 lb

This collection holds Medium Heavy Duty Casters with polyurethane, nylon and rubber wheels, built for shop carts, equipment, and material handling carts that move heavier loads. Casters in this collection range from 300 to 2,000 lb per caster. Wheels in this category range from 3 up to 10 inches in diameter with 1 to 2-1/2 in tread widths. The collection includes swivel, rigid, and brake models. Flanged and V groove track wheels ride on rail or angle iron track for straight line travel. Polyurethane (poly or urethane) treads are quiet, floor safe, and resist water and many chemicals. Nylon rolls easily, resists water and many chemicals, and is hard, so it is loud on rough floors. Rubber wheels are quiet, cushion the load, and protect floors. Soft rubber or TPR is the better pick when the floor has chips or grit. Choose swivel casters when the cart must turn in place and rigid casters for straight travel. Polyurethane aisle: polyurethane casters. Wheel hub: replacement wheels.

Mount: most Durastar medium heavy duty casters use a 4 x 4-1/2 in top plate; 4-1/2 x 6-1/4 in plates are listed too; match the bolt holes on your frame to the plate before ordering.
