Description
Custom RoHS Compliant Polyurethane Wheels for Electronic Carts – OEM/ODM PU Wheel Manufacturer in China for Medical, Laboratory and Warehouse Carts
Built in our own China factory with more than ten years of dedicated polyurethane wheel manufacturing experience, these custom RoHS compliant polyurethane wheels for electronic carts pair a high-grade PU tread with a reinforced steel or aluminum core, giving wholesale buyers a compliant, dependable and competitively priced wheel solution for hospitals, laboratories, warehouses and electronics assembly lines. Because the compound is formulated for low rolling resistance and strong abrasion resistance, electronic carts roll more smoothly, operators use less push effort, and the tread holds its shape far longer than ordinary rubber alternatives, which translates into fewer wheel replacements, less equipment downtime and lower maintenance cost across the working life of each cart. Every production batch is checked for hardness consistency and dynamic balance, and full RoHS test documentation ships with every order. If your project calls for a specific diameter, hardness, bearing type, colour or branded packaging, our engineering team is ready to run a complete OEM or ODM programme from first sample through mass production.
Why Choose This Product
These wheels are produced in our own facility under strict in-process quality control, so buyers purchase directly from the manufacturer rather than through trading layers. That structure keeps pricing stable, keeps lead times predictable and keeps technical communication short. The polyurethane tread is engineered around two priorities that matter most on electronic carts: low rolling resistance and high abrasion resistance. The result is a wheel that starts easily, tracks quietly and keeps its roundness after thousands of working hours, which is a marked improvement over carts fitted with standard rubber wheels that flatten, mark floors and need frequent replacement.
Customization is where this product really separates itself. Hardness can be tuned between Shore A 80 and 95, wheel diameter between 50 mm and 200 mm, and the core can be supplied in steel for maximum load capacity or aluminum when weight reduction matters. Bearing type, axle bore, tread colour and even laser-marked branding can all be adapted to your market. Our engineers will review your load, floor surface and noise target, then recommend a configuration that balances performance with unit cost, offering practical advice rather than a generic catalogue recommendation.
Typical installations include medical and nursing carts, laboratory trolleys, electronics assembly stations, warehouse picking carts, cleanroom transport equipment and automated guided vehicles. Whether you are testing a small trial batch or placing a bulk wholesale order, the formula and structure can be adjusted to suit your specific working conditions.

Frequently Asked Questions
1. What is the minimum order quantity for custom RoHS compliant polyurethane wheels for electronic carts?
Our standard MOQ is 200 pieces per specification. For trial orders or new projects we can sometimes accept smaller quantities, so please share your requirements and we will confirm the most practical arrangement for your situation.
2. Can you customize the hardness and diameter for our electronic cart?
Yes. As a manufacturer with in-house mold and casting capability, we can adjust hardness from Shore A 80 to 95, wheel diameter from 50 mm to 200 mm, bearing type, core material and tread colour. Share your load, floor condition and noise target, and our engineers will suggest a suitable configuration with a realistic cost estimate.
3. Are these polyurethane wheels RoHS compliant?
Yes. The polyurethane compounds we use meet RoHS requirements, and we can supply test reports with bulk orders. If your market has additional regulations, please let us know in advance so we can confirm feasibility before production starts.
4. How do polyurethane wheels compare with rubber wheels for electronic carts?
Polyurethane generally offers lower rolling resistance, higher abrasion resistance and better load capacity than standard rubber, while producing less rolling noise and leaving fewer marks on floors. For electronic carts used in hospitals, labs or electronics assembly, this usually means easier pushing, quieter operation and a noticeably longer wheel life.
5. What is the typical lead time for bulk orders?
For standard configurations, lead time is usually 15 to 25 working days after order confirmation. Custom molds or special materials may require additional time. We will confirm the exact schedule before production begins and flag any raw material risks early.
6. Can I get samples before placing a bulk order?
Yes. We can provide samples for evaluation. Sample cost and freight are normally paid by the buyer and can be discussed against future bulk orders. Please share your specification so we can prepare the right sample the first time.
7. What payment methods do you accept?
We commonly accept T/T and can discuss other terms for long-term partners. Payment terms are confirmed in the proforma invoice before production begins, so there is no ambiguity on either side.
8. How are the wheels packed for international shipping?
Wheels are packed in cartons on pallets, with protective film and separators to prevent scratches during transit. Custom packing and labelling can be arranged for OEM orders, including your own brand marks and shipping marks.
9. What is the typical lead time for a customized PU wheel, for example 150 mm with a steel core?
For small batch custom orders, typical lead time is around 15 to 25 working days, but this may vary depending on raw material supply and shop load. Larger wholesale orders of 100 pieces or more may take 30 to 40 working days. We always provide an updated schedule when you place the order.
10. How do you ensure quality consistency across batches?
Each batch undergoes hardness checks, bonding inspection, dynamic balance verification and load validation before packing. As an ISO 9001 workshop we follow strict in-process inspection rather than relying only on final testing, because wheel failure on a customer’s assembly line is far more expensive than the wheel itself.
11. What warranty do you offer on these polyurethane wheels?
Our standard warranty is 180 days from the shipment date against manufacturing defects. An extended warranty can be discussed for bulk orders. Normal wear and tear, overload or improper installation is not covered, and we will always look at the working conditions with you before making any judgement.
12. Which shipping methods are available?
We ship by express courier for small parcels, by air freight for medium volumes, and by sea freight for full containers. We will advise the most cost-effective option based on your destination and how urgently you need the wheels on site.
13. Do you support OEM and ODM projects with drawing modification?
Yes. Our engineering team supports 2D and 3D drawings for mounting patterns, bolt circles, axle bore sizes and tread profiles. Send us your design file or a sample, and we will confirm feasibility, tooling requirement and unit pricing before you commit to a production run.
