Our Ergolastomer wheel is a solid cast polyurethane-elastomer tread which is mechanically locked to a glass-filled nylon core. This caster is very strong and durable with high impact and abrasion resistance. Its sealed precision ball bearings and crowned tread significantly helps reduce rolling resistance, swiveling action and push/pull forces required to move. These wheels are maintenance free and non-marking with virutally no tread wear.
The casters in our 61/62 Kingpinless Series are heavy duty and forged, with capacities up to 7,000 lb.The series offers matching swivel and rigid casters constructed with 5/16″ thick swivel head from hot forged ASTM1045 steel. The legs are 3/8″ thick and the axle used is 3/4″ thick making these casters hold up to the toughest of jobs. The swivel casters feature a 3′ precisely machined kingpinless raceway of 1/2″ ball bearings.
