Description
Custom Non Marking Polyurethane Wheels for Food Conveyors – Food Grade PU Rollers from a China OEM/ODM Manufacturer
Why Choose These Non Marking Polyurethane Wheels for Food Conveyors?
A marking wheel is never just a wheel problem. It becomes a rejected batch, an unplanned cleaning stoppage and a complaint from your customer. These non marking polyurethane wheels are built around three practical needs on a food line: a clean contact surface, predictable running behaviour, and a supply chain that keeps your conveyor moving.
Each wheel combines a machined aluminium or 304 stainless steel core with a food grade polyurethane tread in Shore A 85° to 95°. That construction holds its shape better than an all plastic roller, absorbs shock, and resists water, mild detergents and repeated washdown cycles, so your maintenance team replaces fewer wheels and your line stays aligned at speeds up to 1.5 m/s.
Typical applications: Food conveyors, filling and weighing lines, packaging and wrapping equipment, bakery and confectionery handling, and washdown areas in food processing plants.
- Food grade polyurethane tread in Shore A 85° to 95°, formulated to leave no visible mark on white paper even after long running cycles.
- A machined metal core with tight tolerances holds its shape better than an all plastic roller, which means less vibration and fewer tipped products at higher line speeds.
- Aluminium or 304 stainless steel hub options with plain bore, sleeve bushing or sealed bearings suit wet, humid and washdown areas in food processing plants.
- Full customization: outer diameter, tread width, bore, keyway, tread colour, hardness and logo engraving for OEM and ODM projects.
- Tested and documented: hardness, concentricity, dynamic balance and a marking check are recorded batch by batch.

Material Properties – Food Grade Polyurethane Compound
The figures below are typical values from our standard food grade polyurethane compound. Hardness and resilience can be adjusted for very light loads or for heavy duty conveyor applications, and we will advise on the best balance between grip, wear life and noise for your line.
| Property | Typical Value | Test Method |
|---|---|---|
| Tread Hardness | Shore A 85° ± 3° | DIN 53505 |
| Tensile Strength | ≥ 35 MPa | DIN 53504 |
| Tear Strength | ≥ 55 kN/m | ISO 34-1 |
| Abrasion Loss | ≤ 35 mm³ | ISO 4649 |
| Compression Set at 70 °C, 22 h | ≤ 20% | ISO 815 |
| Rebound Resilience | ≥ 40% | DIN 53512 |
| Marking Behaviour | No visible marks after 1,000 cycles on white paper | In-house conveyor test |
| Service Temperature | -20 °C to +80 °C | Static and dynamic service |
| Chemical Resistance | Water, mild detergents, common cleaning agents | Immersion test |
Compared with silicone, NBR or plain rubber treads, food grade polyurethane generally delivers higher abrasion resistance and load bearing capacity, which translates into longer service life and fewer replacements on continuous food conveyor lines. Custom hardness from Shore A 85° to 95° is available from our factory.

Frequently Asked Questions – Non Marking Polyurethane Wheels for Food Conveyors
1. Can these non marking polyurethane wheels be used on conveyor lines that handle unpackaged food?
Yes, they are commonly used on lines handling unpackaged food, although the right choice always depends on the application. Our food grade polyurethane compound is formulated to be non marking and resistant to water, mild detergents and ordinary cleaning agents. If your line needs documented food contact compliance, tell us the standard you work to and we will confirm which compound and which documents we can supply before you place an order.
2. How do I choose between polyurethane and silicone coated wheels for my food line?
Both are non marking, but they behave differently under load. Silicone coated wheels are usually chosen for very light loads and gentle contact where a soft touch matters most, while polyurethane handles higher loads, faster line speeds and repeated washdown without flattening. Send us your load per wheel, line speed and cleaning routine, and our engineers will give you a straight recommendation rather than a guess.
3. Can you customize the size, hardness and bore for our existing food conveyor?
Yes. As a China based manufacturer we produce custom non marking polyurethane wheels to your drawing, including outer diameter, tread width, bore, keyway, hub profile, tread colour and hardness from Shore A 85° to 95°. For OEM and ODM projects we can also add your logo or part number. A simple sketch or a sample wheel is enough for us to start, and our engineering team will confirm feasibility before you commit.
4. What is your MOQ, and do you accept trial orders?
Our standard MOQ is 50 pieces per size for regular dimensions. For customized wheels we usually ask for 100 pieces per size because of tooling and compound setup, but trial runs of 20 to 50 pieces can be discussed when you need samples for validation. Wholesale and long term contract pricing is available once the specification is confirmed.
5. How do you control quality before shipment?
Each batch is checked for hardness, concentricity, dynamic balance and surface appearance, and we run a marking test on a white paper surface to confirm the tread leaves no visible mark. Inspection reports and material certificates can be issued with the shipment, and third party inspection arranged by your side is welcome.
6. What is the lead time, and how are the wheels packed?
For regular sizes we usually ship within 7 to 15 working days after the deposit is received. Customized wheels typically take 15 to 30 working days depending on quantity and compound. Lead time can shift with raw material supply and peak season, so we confirm a realistic schedule when the order is placed. Wheels are packed in cartons with protective sleeves, then on export pallets or in wooden cases as required.
7. Which payment and shipping methods do you support?
We normally work with T/T and can discuss other terms for repeat orders. Shipments go by sea, air or express depending on volume and urgency, and we can quote FOB, CIF or DDP terms. Tell us your port or warehouse and we will work out the most practical option for your market.
8. Can I get a price suggestion for a complete food conveyor project?
Yes. Send us the wheel sizes, quantity per size, load per wheel and line speed, and we will prepare a quotation with volume discounts. If you are still at the design stage, our engineering team can review your conveyor layout and suggest a specification that balances cost against service life.
