Ergonomic Casters Put Safety First


Ergo-X2 Caster Series designed to reduce the force needed to push or pull carts. The new 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.
