Maintenance Free - Ergo Extreme Casters

These sealed maintenance free casters cut push force for carts that move all day. Casters in this collection range from 750 to 1,200 lb per caster. Wheels in this category range from 4 up to 8 in by 2 in wide on 4-1/2 x 6-1/4 in plates. Sealed bearings and swivel sections keep out dirt and do not need grease. Polyurethane (poly or urethane) treads, including Hamilton Duralast, protect floors. Soft polyurethane on aluminum (~85 Shore A) 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, 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. Ergonomic aisle: ergonomic casters. Hamilton aisle: hamilton casters.
