Fits 1-1/8" Id Tube

This collection holds Fits 1-1/8 in Id Tube casters with polyolefin, polyurethane and rubber wheels, built for light carts, racks, and stands. Casters in this collection are rated 300 lb per caster. Wheels in this category range from 3-1/2 up to 5 inches in diameter with 1-1/4 to 1.312 in tread widths. The collection includes rigid models. Polyolefin is light, low cost, and resists water and many chemicals. It is hard, so it is loud on rough floors. Polyurethane (poly or urethane) treads are quiet, floor safe, and resist water and many chemicals. 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. Common uses include food service, bakeries, hospitals, schools, laboratories, and material handling carts. Threaded stem, grip-ring, and expanding rubber stems for round and square tubing all appear on light-duty builds. Match the stem size and thread before you order. Polyolefin aisle: polyolefin casters. Wheel hub: replacement wheels.
