This collection holds Son of Mini-Mite casters with metal, nylon and polyurethane wheels, built for heavy equipment, dies, molds, and plant carts that move very heavy loads. Casters in this collection range from 2,500 to 6,000 lb per caster. Wheels in this category are 8 inches in diameter with a 3 in tread width. The collection includes swivel and rigid models. Dual wheel casters split the load over two wheels and swivel with less effort under heavy loads. Metal wheels roll with low effort and handle debris and heat. They are loud and can mark finished floors. Nylon rolls easily, resists water and many chemicals, and is hard, so it is loud on rough floors. Polyurethane (poly or urethane) treads are quiet, floor safe, and resist water and many chemicals. Choose swivel casters when the cart must turn in place and rigid casters for straight travel. Forged steel aisle: forged steel casters. Wheel hub: replacement wheels.
