Four wheel choices for light-duty stainless — pick by floor and environment
Most-ordered
Polyurethane on Stainless
Non-marking TPU tread on a stainless hub. Quiet, floor-protective, chemical resistant. The default for lab carts, hospital trolleys, and food-prep equipment on finished floors.
Maximum sanitation
Solid Stainless Wheel
All-stainless wheel and rig. Zero water absorption, fully steam-cleanable, no crevice for bacteria. The choice for the strictest washdown and cleanroom protocols.
Chemical splash
Phenolic on Stainless
Phenolic wheel resists oils, solvents, and many chemistries that degrade polyurethane. Good for lab and light-industrial chemical environments.
Quiet + cushion
Thermoplastic Rubber on Stainless
TPR tread for the quietest roll and the most cushion. For hospital and lab equipment where noise and vibration matter as much as corrosion resistance.
Why plate mount for light-duty stainless — Plate-mount casters bolt onto a flat mounting surface with four bolts, which makes them easy to install, easy to replace, and easy to inspect. For equipment that gets audited (hospital, pharma, food), the bolt-on plate also makes it simple to demonstrate that the caster is the specified part. Stem-mount casters exist for stainless light-duty too, but plate mount dominates because of the inspection and replacement advantages.
Where light-duty stainless plate casters belong
The list is long because so much equipment lives at this load tier: laboratory instrument carts and trolleys, hospital supply and linen carts, food-service prep tables and bus carts, cleanroom racks and equipment stands, pharmaceutical light equipment, commercial kitchen mobile equipment, and any light cart that rolls through a wash-down zone. What unifies them: the load is light, the environment is corrosive or sanitary, and the equipment gets cleaned constantly.
304 stainless — the light-duty standard, and when to go past it
Standard light-duty stainless plate casters use 304 stainless, which handles the corrosion load of nearly every food-service, lab, and hospital environment. The exception is chloride exposure — saltwater, certain meat-curing brines, some pool and spa chemistries, and a handful of aggressive lab reagents. Chlorides pit 304 stainless over time. For those environments, specify 316 stainless, which adds molybdenum specifically for pitting resistance. If you’re not sure whether your environment has a chloride problem, the cleaning chemistry SDS will tell you.

Light-duty stainless FAQs
Is a polyurethane wheel still “stainless” enough for washdown?Yes — the polyurethane itself doesn’t corrode, and the hub and rig are stainless. The only fully-stainless wheel option is the solid stainless wheel; polyurethane-on-stainless is fully washdown-compatible for all but the strictest cleanroom protocols.
What top plate size is standard?Light-duty stainless plate casters typically use a 2-3/8″ x 3-5/8″ or 2-1/2″ x 3-5/8″ plate. Confirm your equipment’s bolt pattern before ordering replacements.
Do these come with brakes?Yes — stainless brake options are standard, including total-lock for equipment that needs to stay parked precisely.
Will they pass a hospital biomed inspection?Genuine all-stainless plate casters with sealed bearings pass standard biomed review. Make sure the caster is true stainless (not stainless-plated) — that’s the detail inspections catch.
How do I know if I need 316 instead of 304?Check your cleaning chemistry for chlorides. Chloride exposure pits 304 over time. No chlorides — 304 is fine and costs less.
