Hamilton's new Ergo Caster Series is a marriage of our best rolling and quietest polyurethane wheels mounted in Hamilton’s newest Spinfinity ZFWH & ZFHS maintenance-free kingpinless casters. These casters were specifically designed to satisfy the high standards established by the leading ergonomists and safety managers in today’s manufacturing environments.

The new Ergo Caster series features three different wheel types. The Ergo-Tech is the easiest wheel to push with the best (lowest) push/pull force but it’s lightweight aluminum core is not recommended for tough environments. The Ergo-Glide provides a respectable push/pull force and with its heavy duty cast iron core is more durable and recommended for tougher environments. The Ultralast is reserved for those toughest application where all else fails and outperforms the other two wheels but comes with a much higher cost. Note: the 52K models are not maintenance-free casters and are offered as a low-cost alternative to the maintenance-free ZFWH & ZFHS models.
