SA (Shock-Absorbing) Series Casters
Shock Absorbing Casters
As an American caster manufacturer, RWM Casters produces shock-absorbing casters with a heavy-duty, spring-loaded design that cushions loads while moving across uneven terrain. These shock absorbing caster wheels reduce the shock and vibration transferred to carts, trucks, racks, and the materials they carry. For sensitive equipment or valuable cargo, they help protect loads across rough floors and demanding industrial application environments.
Our shock-absorbing swivel casters have load ratings ranging from 100 to 18,000 pounds for light- to heavy-duty industrial applications. Their spring-loaded suspension supports smoother movement, while enhanced swiveling action improves control and maneuverability. Review our caster wheel selection charts to compare capacity ranges and wheel materials.
RWM Casters manufactures these spring-loaded casters in the U.S. for durable, high-performance service in demanding environments.
