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.
Lock-up in this context occurs when the cart is brought to rest and at least two casters rotate to positions in which two or more wheels become substantially misaligned. 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.
