Fits 1-5/8" Id Tube

This collection holds Fits 1-5/8 in Id Tube casters with polyolefin and polyurethane wheels, built for light carts, racks, and stands. Casters in this collection range from 250 to 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 swivel and 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. 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. Choose swivel casters when the cart must turn in place and rigid casters for straight travel. Polyolefin aisle: polyolefin casters. Wheel hub: replacement wheels.
