04 Series

These 04 series casters pack a high rating into a compact 3 in wheel for low carts, machine bases, and equipment that sits low. Casters in this collection range from 500 to 700 lb per caster. Wheels are 3 x 1-13/16 in in glass filled nylon, polyolefin, and polyurethane (poly or urethane). Nylon carries the most and rolls easily on smooth concrete. 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, rigid casters for straight travel, and add a brake when the cart needs to stay put. Capacities below are per caster unless a listing says set. Read the listing for the exact wheel size, overall height, and mount shown. Low profile aisle: low profile casters. Heavy duty hub: heavy duty casters.
