Diameter: 6, 8, 10, 12 inTread: 3 inCapacity: up to 5,000 lb
Polyurethane casters here serve warehouse carts on epoxy and smooth concrete. Typical builds show wheel diameters 6, 8, 10, 12 in, polyurethane treads, and plate-mount frames. Use kingpinless or heavy plate series when shock loads keep shearing kingpin races. When floors see chemicals or washdowns, prefer sealed bearings and non-absorbent wheel compounds. These heavy-duty options cover everyday warehouse carts on epoxy and smooth concrete without jumping to extreme forged series.

Extra Heavy Duty Caster Series with Ergo-Glide XT Wheels


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.
