Expanding Stem Casters for 7/8" ID Tube · 210–325 lb · Polyurethane & Rubber · Expanding Rubber Stem

These expanding stem casters for 7/8 in ID tube fit light carts, racks, and stands. Casters in this collection range from 250 to 350 lb per caster. Wheels are 3 to 5 x 1-1/4 polyurethane, TPR, and polyolefin in swivel and brake models. Expanding rubber stems press into round or square tubing and grip as the bolt is tightened. Softer polyurethane or soft rubber or TPR tread 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. Measure the inside diameter of the tube and order the matching expanding stem. Choose swivel casters when the cart must turn in place, rigid casters for straight travel, and add a brake when the cart needs to stay put. Stem aisle: expanding stem casters. Light duty hub: light duty casters.
