Description
Custom Food Grade Polyurethane Wheels for Bakery Carts
Our custom food grade polyurethane wheels for bakery carts are engineered for bakeries, central kitchens and food processing plants that move dough troughs, proofing trolleys, bread racks and cooling carts across tiled or epoxy floors every single day. The tread is cast from food grade polyurethane at Shore A 85±2, a hardness we selected after repeated shop tests because it keeps the wheel rolling smoothly under load while still absorbing the small floor joints and drain covers that shake loose dough and damage trays. Unlike standard black rubber or hard nylon casters, this food grade PU formula resists oils, dough residue and daily sanitising agents, and it leaves no scuff marks or rubber crumbs on the floor, which helps your team keep the production area inspection ready. Paired with 304 stainless steel sealed bearings, these wheels run quietly enough for night shifts and reduce the vibration that shortens the life of cart frames and shelf brackets. As a China factory with more than ten years of export experience, we supply this wheel as a professional custom solution: choose diameter, tread colour, hub material, mounting type and load rating, and our engineers give expert advice so the finished wheel matches your cart design, your cleaning routine and your budget. Units are for sale in wholesale quantities, and OEM and ODM orders are welcome.
Why Choose Our Bakery Cart Polyurethane Wheels
Most bakery carts fail at the caster, not at the frame. Wet floors, flour dust, hot washdown and constant turning load concentrate stress on the wheel, and that is exactly where we put our engineering effort. Our food grade polyurethane compound is formulated for low moisture absorption, so the tread does not swell or go soft after repeated cleaning, and the mechanical bond between tread and hub is controlled in-house rather than outsourced. Compared with pure nylon wheels, our PU tread cuts rolling noise noticeably and protects delicate floor coatings; compared with cheap grey rubber casters, it lasts considerably longer under the same load and does not shed black marks into dough handling areas.
- Food grade polyurethane tread, low odour and low marking on white or light grey floors
- 304 stainless steel double ball bearings with sealed covers for washdown zones
- Optional aluminium alloy, stainless steel or reinforced nylon hub, matched to load and hygiene needs
- Very low moisture absorption, so the wheel keeps its shape in humid proofing rooms
- Stable rolling resistance from 80 kg to 250 kg per wheel, depending on size
- Full customisation: size, colour, hardness, mounting type and branding

Product Details and Application Images
Detail photographs show the cast polyurethane tread surface, the mechanical bond line between tread and hub, the sealed stainless steel bearing seat, and the finish of the mounting plate or stem. Close-up shots also show the tread profile after load testing, so buyers can judge wear behaviour before ordering. Application photographs show these wheels fitted to dough troughs, bread cooling racks, ingredient transfer trolleys and mobile stainless steel work tables in working bakeries. Each image is labelled with the wheel diameter, mounting type and load it carries, which makes it easier to match a wheel to your own cart drawing.
Material Properties
These figures come from our own incoming material checks and finished wheel tests. They describe typical performance for standard production, and we can adjust the compound when your operating conditions call for a different balance of hardness, grip or chemical resistance.

About ZHXPRECI – China Factory for Food Grade PU Bakery Cart Wheels
About Us
Customers Visiting
We are a China factory and supplier of cast polyurethane and rubber wheels for industrial and food handling equipment, working with bakery equipment builders, food processing plants and wholesale distributors in more than thirty countries. Since 2010 our team has focused on one narrow field: wheels that have to survive wet, oily, dust-loaded or hygiene controlled environments. That focus is why we keep in-house control over compound mixing, casting, curing, machining and final inspection instead of buying finished treads on the open market. We handle OEM, ODM and OBM projects, and we are happy to work as your professional custom solution partner from the first drawing to the shipping carton.
Customers usually come to us with a real problem rather than a catalogue request, such as wheels that crack after three months of washdown or casters that leave rubber marks on a newly coated floor. We treat that as a design brief. Our engineers review your cart drawing, load distribution, floor type and cleaning chemicals, then give expert advice on diameter, hardness, hub material and bearing choice. Where a standard size fits, we quote from the existing range; where it does not, we build a custom solution with our own tooling and sample it before mass production. Buyers from Europe, North America, Southeast Asia and the Middle East visit our factory each year to audit production, review sample measurements and discuss new cart projects, and during these visits we run live casting and load test demonstrations so customers can see how a compound change affects hardness and wear before placing a bulk order.
Factory and Equipment
Our production line covers the full process: polyurethane mixing and casting, curing ovens, CNC machining for hubs and axles, precision boring for bearing seats, assembly, dynamic balancing checks and final load testing. Dedicated stations handle stainless steel bearing fitting and sealing, which matters for food area wheels that are cleaned daily.
- Polyurethane casting lines with controlled mixing ratio and curing schedule
- CNC lathes and machining centres for aluminium and stainless steel hubs
- Dynamic balancing and concentricity checks on finished wheels
- Load and rolling resistance test benches with recorded results per batch
- Salt spray and humidity test cabinet for stainless steel bearing assemblies
- Final visual and dimensional inspection with traceable batch records
Certifications and Quality Documents
Our factory operates under an ISO9001 quality management system, and our food handling wheels can be supplied with raw material documentation covering food contact suitability, RoHS and REACH declarations. Third-party inspection by SGS, Bureau Veritas or TUV can be arranged before shipment, and we keep batch records for material, hardness and load tests so that any question can be traced back to production data.
Production and Inventory Policy
Lead time: Actual lead time depends on raw material supply, machine scheduling and peak season workload, so it can vary within a reasonable range. Once your order is confirmed we provide the most accurate delivery estimate we can and keep you updated throughout production.
Stock status: We do not normally hold finished stock, although a number of fast-moving standard sizes are kept on the shelf. Those quantities change constantly with sales and production, so please contact us to confirm real-time availability before placing an order.
Bulk and urgent orders: For large volume or urgent requirements, please talk to us early about capacity and scheduling. We will do our best to fit your timeline, and we will tell you honestly if a date is not realistic.
Frequently Asked Questions – Food Grade Polyurethane Bakery Cart Wheels
Are these polyurethane wheels genuinely suitable for direct food contact areas?
The tread is produced from food grade polyurethane raw material, and we can supply material documentation for your hygiene or compliance review. The wheels are designed for bakery carts, proofing trolleys and food transfer equipment where crumbs, flour dust and washdown are normal. If your application requires a specific food contact certificate or a particular regulatory standard, tell us at the enquiry stage and we will confirm what documentation we can provide for your market.
Can you customize wheel size, colour and mounting to match our existing bakery carts?
Yes. Customization is our main business rather than an add-on. Send us your cart drawing, axle diameter, mounting hole pattern and required load per wheel, and our engineers will propose a matching diameter, tread hardness, hub material and bearing type. We support OEM and ODM projects, including custom tread colours and your brand marked on the hub or packaging, and we usually produce a sample for approval before mass production begins.
What load can a single 125 mm food grade polyurethane wheel carry?
A 125 mm wheel in standard configuration typically carries around 120 kg to 150 kg per wheel, but the real figure depends on hub material, bearing type, mounting method and how the cart distributes its weight. Bakery carts often load unevenly, so we recommend choosing a wheel rated above the calculated static load and confirming the number by a simple load test. Our team can review your cart layout and give a specific suggestion.
How do these wheels behave on tiled floors that are washed and sanitised every day?
The polyurethane compound has very low water absorption, so the tread does not swell or soften after repeated cleaning, and the sealed stainless steel bearings keep water and detergent out of the rolling elements. The non-marking tread also means no black streaks on light tiles, which reduces cleaning work and helps you pass hygiene inspections. If your cleaning routine uses strong chemicals, tell us which ones and we will confirm compound compatibility.
Do you offer wholesale pricing for volume orders?
Yes. We are a manufacturer rather than a trading company, so pricing is based on material, machining and finishing cost instead of resale margin. Wholesale prices improve as order quantity grows, and we are happy to give a price suggestion for your market so you can plan your own selling price. Contact us with quantities and specifications and we will send a quotation with volume tiers.
What is your minimum order quantity, and how long does delivery usually take?
MOQ is generally 50 to 200 pieces depending on size and level of customisation, and small trial orders can be discussed for new customers. Standard sizes usually ship in 7 to 20 working days after order confirmation, while fully custom wheels with new tooling take longer. Raw material supply and peak season workload can affect the schedule, so we always confirm the date in writing before production starts.
What warranty and after-sales support do you provide on custom wheels?
Every batch leaves our factory with recorded material, hardness and load test data. If a wheel fails to meet the agreed specification within the warranty period, we will investigate against the batch record and, where the issue comes from our manufacturing, arrange replacement or credit. For OEM projects we agree the warranty terms in the contract so both sides know exactly what is covered. Day-to-day technical questions after delivery are handled by the same engineer who worked on your order.
Can you supply samples before we place a bulk order?
Samples are available for evaluation, and for custom projects we normally produce a pre-production sample so you can test it on your own cart and floor. Sample cost and courier charge are usually refundable or deductible against the bulk order, depending on quantity. We will confirm the exact terms when we quote.
