Ergonomic Casters Designed to Satisfy Safety Mangers

Hamilton's 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 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. Note: the 52K models are not maintenance-free casters and are offered as a low-cost alternative to the maintenance-free ZFWH & ZFHS models.
