Our 53 series shock absorbing casters have swivel sections that are constructed of high alloy steel and are precision machined for close tolerances and long life. The high strength chrome vanadium springs provide longer life through constant flexing and compressing.
The 53 series’ shock absorbing capabilities offer several benefits including noise reduction and cargo protection. Our spring loaded casters are designed for optimal spring deflection, maintaining a perfect balance of rigidity and shock absorption.
