Description
Custom Weld-On Polyurethane Wheels for Heavy Trailers — Factory Direct OEM/ODM Supply
Our custom weld-on polyurethane wheels for heavy trailers are produced in our own China factory from a machined top-grade 45# carbon steel hub and a hot-cast polyurethane tread that is chemically bonded to the metal, so the wheel can be welded straight onto your trailer frame without extra brackets, adapters or bolt-on hardware. Compared with plain rubber or cast iron wheels, the 92 Shore A polyurethane tread resists cutting, chunking and abrasion far better on concrete, asphalt, steel deck and gravel yards, which means fewer replacements and shorter downtime for fleet operators and trailer builders. As a top professional manufacturer and supplier with more than a decade of export experience, we supply these wheels for sale at wholesale price with full customization, OEM, ODM and OBM support — diameter, tread width, hub bore, offset, colour and hardness are all customized to your drawing, and each batch is checked for hardness, dynamic balance and load capacity before shipment, backed by ISO9001 factory procedures and third-party test reports available on request.
Why Choose This Custom Weld-On Polyurethane Wheel
Trailer manufacturers and fleet maintenance teams usually come to us after struggling with wheels that wear out too fast, crack at the hub or vibrate under load. Our answer is a wheel engineered around the weld-on fixing method that heavy trailer axles actually use, which keeps the assembly compact, strong and free of loose fasteners.
- The weld-on steel hub is machined from 45# carbon steel and welded by our own fabricators, giving a rigid, permanent connection to the trailer frame that will not work loose under vibration.
- The hot-cast polyurethane tread is bonded to the hub core, so it holds together under heavy point loads instead of peeling away, and it keeps running smoothly on uneven yard surfaces.
- Because we cast and machine in-house, we can hold the hardness window tightly, which keeps rolling resistance and noise low while still carrying the load your application demands.
- Dynamic balance is controlled to within a small tolerance on our balancing machine, reducing vibration that would otherwise transfer to the trailer chassis and cargo.
- Every batch is tested for hardness, bond integrity and static load before packing, and we can arrange third-party inspection if your project requires documented evidence.

Material Properties
The performance below comes from our standard hot-cast polyurethane compound, tested in our own laboratory and cross-checked with third-party reports. Hardness, abrasion resistance and rebound can be adjusted if your trailer works in a specific environment, for example cold storage, oily workshop floors or outdoor yards, and our engineers are happy to advise on the best combination for your load and surface.
| Property | Test Method | Typical Value |
|---|---|---|
| Shore A hardness | ASTM D2240 | 92 ± 3 |
| Tensile strength | ASTM D412 | ≥ 35 MPa |
| Tear strength | ASTM D624 | ≥ 80 kN/m |
| Abrasion loss | DIN 53516 | ≤ 35 mm³ |
| Rebound resilience | ASTM D2632 | ≥ 45 % |
| Compression set | ASTM D395, 70 h at 23 °C | ≤ 20 % |
| Steel core grade | GB/T 699 | 45# carbon steel |
| PU-to-metal bond | Peel test | No separation at rated load |
| Static load test | 3× rated load | No permanent deformation |
Elastomer Comparison for Heavy Trailer Wheel Applications
Because compound choice and hardness drive most of the wear life in trailer service, the table below compares the elastomers we mould most often for weld-on wheels. Ratings run from 1 (low) to 5 (high) and reflect our own shop-floor experience together with supplier test data, rather than a single laboratory standard.
| Compound | Hardness (Shore A) | Abrasion Resistance | Tear Resistance | Load Bearing |
|---|---|---|---|---|
| Silicone | 40–90 | 1 | 1 | 1 |
| Nitrile/PVC | 20–95 | 4 | 3 | 3 |
| EPDM | 20–95 | 4 | 3 | 3 |
| Nitrile Rubber | 20–95 | 3 | 3 | 3 |
| Neoprene | 5–95 | 3 | 4 | 4 |
| Hypalon | 30–95 | 4 | 4 | 4 |
| Hydrogenated Nitrile | 50–98 | 5 | 5 | 5 |
| Natural Rubber | 25–98 | 5 | 5 | 5 |
| Polyurethane | 20–98 | 5 | 5 | 5 |
| Carboxylated Nitrile | 45–95 | 5 | 5 | 5 |
Polyurethane and natural rubber give the best balance of abrasion resistance and load bearing for weld-on trailer wheels, which is why our standard compound sits at the top of both columns. Silicone is normally chosen for high-temperature or non-marking duties, and EPDM suits outdoor yards exposed to weather and ozone. Tell us your load, running speed and yard surface and we will recommend the compound that genuinely fits, rather than the one that is easiest to mould.
About Us
We are a China-based manufacturer and supplier specializing in custom polyurethane wheels, rollers and casters for industrial and trailer applications. As a top professional factory in this niche, we work directly with trailer builders, fleet operators, distributors and engineering contractors, offering expert advice on compound selection, load rating and mounting design before an order is placed. With more than ten years of experience serving overseas buyers, our team has learned that most quality complaints come from a mismatch between hardness, load and floor condition rather than from the material itself, so we spend time on that conversation first. Our factory runs ISO9001 quality management procedures, and most of our output goes to wholesale and OEM/ODM projects across the European, North American, Middle Eastern and Southeast Asian markets. Because we handle casting, machining, welding and inspection under one roof, we can keep the price competitive while still taking on customized, low-volume and non-standard work that general traders usually avoid.

Certifications and Quality Control
Our factory operates under an ISO9001 quality management system, and our materials are checked against RoHS and REACH requirements for the markets we serve. Where a project needs documented evidence, we can supply material certificates, hardness and load test reports, and we welcome third-party inspection by SGS, BV or your nominated agent before shipment. If you need a specific standard or a sample to be tested at your own laboratory, tell us at the enquiry stage and we will build that check into the production plan.
Production and Inventory Policy
Lead time: Actual lead time is affected by raw material supply, machining capacity and peak-season workload, so it may vary within a reasonable range. Once your order is confirmed, we will give you the most accurate delivery estimate we can and keep you updated throughout production.
Stock status: In principle we produce to order, but a limited number of popular standard sizes are kept in stock. Stock quantities change constantly with sales and production, so we recommend contacting us to confirm real-time availability before you place an order.
Bulk and urgent orders: For large-volume or time-critical projects, please talk to us early about capacity and scheduling so we can plan production around your timeline as far as possible.
Frequently Asked Questions
Can you customize the hardness, diameter and hub bore of these custom weld-on polyurethane wheels for heavy trailers?
Yes. Hardness can be set between Shore A 70 and 98, diameters from 80 mm to 300 mm, and hub bore, keyway or spigot dimensions are machined to your drawing. Send us the axle interface details and the surface your trailer runs on, and our engineers will suggest a compound and hardness combination that matches your load and working environment.
How do I choose between a hot-cast bonded tread and a mechanically locked tread?
For most heavy trailer work the hot-cast chemical bond is the right choice, because it spreads load evenly across the whole tread and keeps vibration low. A mechanically locked tread becomes worth considering when the wheel sees very high shear forces, repeated side impacts or frequent temperature swings, since the lock gives a second line of defence if the bond is ever stressed. Tell us how the wheel is used and we will recommend one option clearly rather than leaving the decision to you.
What is the minimum order quantity and how is the wholesale price calculated?
Our standard MOQ is 50 pieces per size, and we can accept a smaller trial quantity for a first order. Price depends mainly on diameter, tread width, hardness and hub machining complexity. Because we are a factory rather than a trading company, we can quote directly from our own cost structure and pass the saving on in volume orders.
How long does production take, and how do you ship?
Typical lead time is 15 to 25 days after deposit and drawing confirmation, though this can shift with material supply and peak season. We usually ship by sea for bulk orders, by air or express for samples and urgent lots, and we can work with your nominated forwarder or arrange shipping on our side.
What payment methods do you accept?
We normally work on a deposit plus balance before shipment, by T/T or through a trade assurance channel if your platform supports it. For long-term projects and repeat orders, we can discuss more flexible terms based on order history and volume.
How do you control quality before shipment?
Each batch goes through hardness testing, bond inspection and a static load check against the rated capacity, and larger wheels are balanced on our balancing machine. We keep inspection records for every shipment and can arrange third-party inspection if you prefer independent verification.
Can I get a sample before placing a mass production order?
Yes. We can produce a sample to your drawing or match an existing sample you send us. Sample lead time is usually shorter than mass production, and the sample cost is normally refundable or credited against the bulk order depending on the specification.
Do you offer OEM, ODM or private label service for these weld-on trailer wheels?
We do. We can cast or machine to your drawing, apply your brand marking, pack in your own carton design, and support OBM projects where you need a ready product line under your own brand. Tell us your target market and application, and we will advise on the specification that fits it best.
What warranty or after-sales support do you provide?
We cover the wheel against manufacturing defects such as bond separation or hub machining faults for a period agreed in the contract, typically 12 months from shipment. Wear life depends on load, speed, floor condition and operating hours, so we do not quote a fixed mileage figure; instead we help you select the right hardness and compound up front, and if a batch does not behave as specified we will investigate with you and work out a fair replacement plan.
