Modern Suspension Systems Casters


Modern Suspension Systems offers an extensive line of steel or aluminum spring loaded, light to heavy duty shock absorbing and vibration damping casters. Our casters utilize our Vari-Flex linear suspension system, which achieves optimal shock reduction, and drastically reduces shimmy, dynamic bounce and resonance when the cart is empty, or loaded beyond its rated capacity. Our dual wheel models feature a completely independent suspension. Each wheel is on its own separate axle with separate legs. This helps to keep both wheels on the ground and help keep the load level, even when the ground isn’t.  It also helps avoid excessive stress on just one wheel, reducing the risk of failure and potential injuries.

With our all-aluminum casters, the overall weight of the caster is reduced to about 1/3 the weight of equivalent steel and iron core wheels and is the ideal choice in wet and humid environments.


Independent Suspension – Each wheel is on its own separate axle with separate legs

Shock Isolation – Significantly reduces vibration and noise and lowers risk of load damage

Corrosion Resistant – Ideal for outdoor use and stands up to water and many chemicals
