This collection holds Hi-Lo casters with polyurethane, phenolic and ergonomic polyurethane wheels, built for light carts, racks, and stands. Casters in this collection range from 250 to 450 lb per caster. Wheels in this category range from 3 up to 5 inches in diameter with 1 to 1-3/4 in tread widths. The collection includes swivel and rigid models. Polyurethane (poly or urethane) treads are quiet, floor safe, and resist water and many chemicals. Phenolic rolls easily on smooth floors and handles dry heat, oil, and grease, but it is not made for water or washdown. It suits warehouse carts, toolboxes, and tool carts, and it is loud on rough floors. Ergonomic polyurethane wheels are made to lower push effort, which helps workers move heavy carts by hand. Common uses include food service, hospitals, schools, laboratories, and material handling carts. Choose swivel casters when the cart must turn in place and rigid casters for straight travel. Polyurethane aisle: polyurethane casters. Wheel hub: replacement wheels.
