06 Series

These 06 series casters use 5 x 1 in wheels for light carts, stands, and fixtures that need a bigger wheel to roll over thresholds. Casters in this collection range from 125 to 145 lb per caster. Treads include polyolefin, thermoplastic rubber, and soft rubber on a 2-3/8 x 3-5/8 in plate. Soft rubber or TPR tread is the better pick when the floor has chips or grit. Threaded stem, grip-ring, and expanding rubber stems for round and square tubing all appear on light-duty builds. Common uses include food service, bakeries, hospitals, schools, laboratories, and material handling carts. Match plate size 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. Light duty hub: light duty casters. Cart aisle: cart casters.

Floor: on Durastar 06 series casters, rubber and polyurethane are kinder to tile and finished floors; polyolefin rolls easier under heavy loads on smooth concrete.
