Capacity Range: 1,300 – 3,800 lbs.
The new Ergo-Glide XT is your best choice among polyurethane wheels for extra heavy loads in environments where cushioning, quiet operation, and/or debris rejection are top priorities. The Ergo-Glide XT is essentially the “big brother” of our popular Ergo-Glide wheels and both are the top poly performers in repelling foreign objects and debris. Factory personnel will also benefit from this wheel’s quiet ride to reduce noise.
The ‘XT’ stands for “Extra Thick” or 1” thick of our quietest rolling polyurethane. The 1” thick tread boasts a higher load capacity than the majority of our polyurethane wheel offerings. The slightly softer 82A urethane combined with the 1” thick tread also allow the wheel to roll over obstacles more easily as the tread will tend to conform to the obstacle rather than roll up and over it.
In slow to moderate speeds the ErgoGlide XT’s thicker tread reduces heat stress on the bond line. And because there’s more polyurethane to compress, the psi pressure is lower and therefore the urethane endures less stress fatigue for longer life.
The new Ergo-Glide XT Wheel is now featured in the majority of Hamilton’s forged steel heavy duty casters. The selection table below offers our most popular sizes but this 1” thick softer tread can also be molded to Hamilton’s other cast iron, forged steel, and/or aluminum centers in finished sizes ranging from 3” to 20” diameter.
