Medium-Duty Casters – 351 to 675 lbs. Per Caster

This collection includes every caster in the CasterHQ catalog rated between 351 and 675 lbs. per caster. These medium-duty casters bridge the gap between light-duty office and warehouse casters and the heavy-duty industrial range, making them ideal for shop carts, assembly fixtures, industrial shelving, and moderate-load transport equipment.

How to Choose a 351–675 lb. Caster

1. Calculate your per-caster load. Divide total cart weight (including maximum payload) by the number of casters, then add a 25% safety margin. If the result falls between 351 and 675 lbs., you are in the right range.
2. Select a wheel material. Polyurethane is the all-around best performer for smooth or finished floors. Phenolic handles high temperatures and heavy static loads. Mold-on rubber provides shock absorption. Semi-steel and cast iron are economical for rough shop environments.
3. Pick your mount type. Top plate is the most common for flat-bottom carts and equipment. Threaded stem works for tapped holes. Expanding adapter fits round tubing on wire racks and shelving units.
4. Choose swivel, rigid, or both. Two swivels + two rigids is the standard four-caster layout. All swivels allow omnidirectional movement but need brakes for parking.
5. Add brakes if needed. Total lock brakes are recommended for any application where the cart must stay parked on a slope or in a fixed position during loading.
