Colson Medical Casters by Wheel Size · 6" Wheels · Up to 1,250 lb · Polyurethane

This collection holds casters with 6 wheels, built for shop carts, equipment, and material handling carts that move heavier loads. Casters in this collection range from 900 to 1,250 lb per caster. Wheels in this category are 6 inches in diameter with a 2 in tread width. The collection includes swivel, rigid, and brake models. Polyurethane (poly or urethane) treads are quiet, floor safe, and resist water and many chemicals. Softer polyurethane or soft rubber or TPR tread 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. Polyurethane aisle: polyurethane casters. Wheel hub: replacement wheels.
