This collection holds Cush-N-Flex casters with rubber wheels, built for shop carts, equipment, and material handling carts that move heavier loads. Casters in this collection range from 700 to 800 lb per caster. Wheels in this category range from 6 up to 12 inches in diameter with 2 to 2-1/2 in tread widths. The collection includes swivel and rigid models. 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. Match plate size, bolt pattern, and overall height before you order. Choose swivel casters when the cart must turn in place and rigid casters for straight travel. Read the listing for the exact wheel size, overall height, and mount shown. Confirm the load rating printed on the title before you order. Measure the old wheel or caster before you buy. Rubber aisle: rubber casters. Wheel hub: replacement wheels.
