Description
Custom Food Grade Polyurethane Wheels for Processing Lines – FDA-Compliant PU Wheels for Food, Beverage, Dairy & Pharmaceutical Conveyor Systems
Why Choose Our Food Grade Polyurethane Wheels
Food processing environments are unforgiving on moving parts. Steam, water, fats, and caustic cleaning agents break down ordinary rubber within months, causing cracking, black marks, and bacterial harborage points. Our food grade polyurethane wheels solve this by combining a non-porous, non-marking surface with high mechanical strength. The result is a wheel that holds its shape under continuous load, keeps floors clean, and passes daily hygiene inspections without special treatment.
As a professional China factory and OEM/ODM supplier, we build each food grade PU wheel around a food-approved compound that we develop in-house. Shore A hardness options from 70A to 95A let you tune the balance between load capacity and shock absorption, while stainless steel or food-grade hub options eliminate rust inside washdown areas. For HACCP-sensitive lines, blue and metal detectable compounds are available to help your food safety program trace broken fragments quickly.
Typical applications: Food processing lines, conveyor systems, packaging equipment, bakery and dairy trolleys, beverage filling stations, pharmaceutical transfer carts, and cold-room handling equipment.

Product Details – Construction & Application
Each wheel is built around three components: the polyurethane tread, the hub, and the bearing system. The tread is cast or CNC-machined to your required profile, with a smooth surface finish that reduces rolling resistance and prevents product buildup. Hubs are available in 304 and 316 stainless steel, food-grade nylon, or aluminum, depending on the washdown environment and structural load. Bearings range from sealed stainless steel ball bearings to precision roller bearings for high-load, low-speed applications. We also offer a range of mounting options including bolt-hole patterns, keyways, and plain bores. Our food grade polyurethane wheels are for sale in trial quantities as well as full production volumes, with OEM and ODM support at every stage.

Frequently Asked Questions – Food Grade Polyurethane Wheels
Are your polyurethane wheels certified for direct food contact?
Yes. Our standard food grade PU compounds are formulated to meet FDA 21 CFR 177.1680 and EU Regulation 10/2011 for repeated food contact. We supply compliance documents, migration test reports, and material safety data sheets with every order on request. This means your hygiene and food safety teams can file the paperwork without waiting for extra test cycles.
How does food grade polyurethane differ from standard PU or rubber wheels?
Food grade PU uses raw materials approved for food contact and is formulated to resist water absorption, oils, and cleaning chemicals without cracking or leaving marks. Standard rubber tends to absorb water and break down faster in washdown areas, while industrial PU may contain additives not approved for food contact. Choosing food grade PU reduces the risk of contamination and black marks on your product handling lines.
Can you customize the wheel size and hub to fit our conveyor or trolley?
Yes. We build fully customized food grade polyurethane wheels based on your drawings or samples, including diameter, tread width, hub bore, keyway, bolt-hole pattern, and bearing type. Send us your specification and our engineers will confirm feasibility and lead time. As a China OEM/ODM factory, we handle both sample-level and full production runs.
What is the minimum order quantity for custom food grade polyurethane wheels?
