Ergonomic Casters

This collection holds Ergonomic Casters Lower Push Force, with ergonomic polyurethane, UltraGlide polyurethane and nylon wheels, built for heavy equipment, dies, molds, and plant carts that move very heavy loads. Casters in this collection range from 450 to 3,000 lb per caster. Wheels in this category range from 2 up to 8 inches in diameter with a 2 in tread width. The collection includes swivel and rigid models. Kingpinless swivels hold up better under shock and repeat loads. Dual wheel casters split the load over two wheels and swivel with less effort under heavy loads. Ergonomic polyurethane wheels are made to lower push effort, which helps workers move heavy carts by hand. UltraGlide polyurethane wheels are made to start and roll with low push effort, which helps on long pushes. Choose swivel casters when the cart must turn in place and rigid casters for straight travel. Polyurethane aisle: polyurethane casters. Wheel hub: replacement wheels.
