Ergo-X2 Swivel Casters

Series: ERGO-X2

The new Ergo-X2 Caster Series is designed to reduce the force needed to push or pull carts. The patented swivel caster design features two precision machined offsetting ball races in a compact assembly to minimize one of the final unresolved issues with swivel casters: lock up.

A typical swivel assembly in a caster has only one pivot point. The Ergo-X2 Caster essentially provides a second pivot point that reduces the startup force to get the cart moving when lock up is present.

Hamilton’s Ergo-X2 reduces these binding forces by providing internal relief via the offset swivel raceways. So the Ergo-X2 paired with one of Hamilton’s low start up poly treads is the safer way forward.

Ergo-X2 puts Safety First

It’s now common for safety managers to demand that push/pull forces be as low as practically possible. Preliminary tests have indicated the force reduction of the Ergo-X2 can be as much as 22%. Safety experts and insurance professionals can vouch for the cost of one back injury, and recognize that an ounce of prevention with something like Ergo-X2 can be worth a pound of neglecting workers’ safety and hoping injuries won’t happen.
