When sensitive loads include heavy weights, shock becomes a real threat. The SL6803 and SL7003 Series spring-loaded casters are engineered specifically to manage that risk, delivering controlled motion, shock isolation, and consistent load distribution where other casters fall short.

Both series follow the same engineering philosophy and are designed as fully integrated systems, not accessories. Impact is absorbed within the caster assembly itself, preventing vibration and sudden shock forces from being transmitted to equipment or cargo.

The SL7003 Series delivers this performance in a more compact footprint, while the SL6803 Series scales the same design principles into higher load ranges with increased structural mass. The SL6803 has a capacity of 1,500 lbs., while the SL7003 can handle up to 1,000 lbs. Both feature double-welded construction for added strength and are engineered to maintain continuous floor contact across uneven surfaces, keeping all wheels engaged and loads evenly shared.

At the core of both designs is a multi-spring architecture that allows performance to be tuned through spring selection. Each series is available with different spring types, enabling engineers to precisely match load capacity and deflection characteristics. As loads increase, heavier spring configurations provide greater deflection control, absorbing shock without bottoming out and maintaining system stability under dynamic conditions. Our patented load indicator displays the amount of weight being borne by the springs.

Within the CAD LAB™, both series can be configured in dozens of variations, with over two dozen wheel options, including RollX™, ProTech™, and Envirothane™, as well as multiple plate, stem, and bearing configurations. Braking options range from the iLock™ wheel-only solution to multi-position swivel locks and the integrated Universal Wheel Brake (UWB), a positive-lock brake welded directly to the caster fork. With the UWB, brake force, engagement angle, and braking point are fully adjustable, with smooth engagement requiring as little as 15 lbs. of pressure.

Manufactured in our fully integrated Toronto facility, the SL6803 and SL7003 Series offer dependable lead times measured in weeks, delivery dates you can count on, and trusted North American quality backed by our 3-Year No Excuse Warranty™. And when customization matters, there is direct access to engineering expertise.

Potential applications for these superbly constructed casters include mobile motion picture staging, aircraft ground support equipment, in-plant trailer parts, trash containers, tool carts, amusement parks, asphalt paving machinery and material handling equipment.
