Stainless Washdown Casters · 3" to 5" · 275 to 800 lb · Polyurethane & Rubber

This collection holds Stainless Washdown Casters with polyurethane, rubber and phenolic wheels, built for shop carts, equipment, and material handling carts that move heavier loads. Casters in this collection range from 275 to 800 lb per caster. Wheels in this category range from 2-3/8 up to 5 inches in diameter with 1-1/4 to 3-5/8 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. Rubber wheels are quiet, cushion the load, and protect floors. 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. Soft rubber or TPR is the better pick when the floor has chips or grit. Choose swivel casters when the cart must turn in place and rigid casters for straight travel. Polyurethane aisle: polyurethane casters. Wheel hub: replacement wheels.

Choosing stainless washdown casters

Load: plan on three casters carrying a four-caster cart [S2]; at 350 lb each, a common rating here, that is about 1,050 lb, and the 800 lb top rating covers about 2,400 lb.
Mount: most stainless washdown casters use a 2-3/8 x 3-5/8 in top plate; 4 x 4-1/2 in plates are listed too; check the bolt spacing on your frame against the plate size.
Floor: on stainless washdown casters, polyurethane and rubber are kinder to tile and finished floors; phenolic and polyolefin roll easier under heavy loads on smooth concrete.
Rig: swivel and rigid stainless washdown casters are listed, with side lock brake options.
