Description
Custom Large Diameter Polyurethane Wheels for Heavy Equipment
Custom large diameter polyurethane wheels for heavy equipment are engineered and produced in our own factory in China, with outside diameters from 200 mm up to 1,200 mm and load ratings up to 8,000 kg per wheel. Instead of shipping a fixed catalogue item, we machine the steel or cast iron hub to your bore, keyway and mounting pattern, then bond a polyurethane tread formulated around your actual duty cycle, floor surface and travel speed. Because the tread is matched to the real load and the hub is machined concentrically before coating, these wheels resist chunking and flat spotting far better than standard rubber or low-grade casters on concrete, epoxy and steel flooring, which means longer service intervals and less unplanned downtime for your equipment. Every production run, whether a single replacement wheel or a wholesale volume order, passes dimensional inspection and durometer testing before dispatch. As a professional China manufacturer and supplier, we support full customization and OEM/ODM programs, and our engineers are glad to give expert advice with a transparent price suggestion for your market. Send us your drawing, axle size and load data to start a quote.
Why Choose Our Custom Large Diameter Polyurethane Wheels
Heavy equipment wheels tend to fail for the same predictable reasons: the tread compound is too soft for the load, the hub is not machined concentrically, or the bond between polyurethane and hub is weak. We built our production line around those three failure points. Each hub is turned on CNC equipment and checked for roundness and concentricity before coating, and the polyurethane is cast and cured under controlled temperature so bond strength stays consistent from the first wheel to the thousandth. Because we are a manufacturer rather than a trading supplier, we can adjust hardness, tread profile and hub geometry within one production cycle instead of asking you to accept an off-the-shelf compromise. That level of control is what keeps heavy duty polyurethane wheels running predictably on transfer carts, conveyor systems and industrial platforms.
- Diameter range from 200 mm to 1,200 mm, suitable for heavy equipment, transfer carts, conveyor systems and industrial platforms.
- Shore A 80 to 95 and Shore D grades available, selected according to load, speed and floor condition.
- Machined steel, cast iron and aluminium hubs with custom bore, keyway, flange or bearing seat.
- OEM and ODM programs supported, including private labelling and custom tread patterns.

Material Properties
The table below shows typical values for our standard heavy-duty polyurethane compound. Values are measured on production samples and are given as typical results rather than guaranteed limits, because the final figure depends on hardness grade, cross-section and curing batch. If your application calls for a compound outside these figures, our technical team can review your load and speed data and suggest a suitable grade.
| Property | Test Method | Typical Value |
|---|---|---|
| Hardness | Shore A durometer | 85 ± 3 Shore A |
| Abrasion resistance | DIN 53516 | ≤ 60 mm³ loss |
| Tensile strength | ISO 37 | ≥ 35 MPa |
| Tear resistance | ISO 34-1 | ≥ 60 kN/m |
| Rebound resilience | ISO 4662 | ≥ 45 % |
| Compression set | ISO 815, 70 °C, 22 h | ≤ 25 % |
| Continuous service temperature | Service condition | -20 °C to +80 °C |
Product Details and Customization Options
A wheel that performs well on a warehouse floor can behave very differently on an outdoor yard or a wash-down area, so we treat every inquiry as a separate engineering case. When you send us a drawing or a worn sample, we check the hub bore, the tread wear pattern and the load distribution before choosing a compound. For light and medium loads, a softer tread keeps noise low and protects delicate flooring. For high-load transfer carts and steel rails, a harder tread with a thicker cross-section resists compression set and heat build-up far better than a standard rubber wheel. This is how a customized heavy duty polyurethane wheel ends up matching the machine rather than the other way round.
- Custom bore diameters, keyways, set-screw holes and flange mounting patterns.
- Tread profiles including flat, crowned, grooved and anti-static versions.
- Optional bearing types and sealed bearing housings for dusty or wet environments.
- Balancing check before shipment for wheels used at higher travelling speeds.
- Private label marking and neutral packing for OEM and ODM buyers.

About Us
We are a professional polyurethane wheel manufacturer and supplier based in China, with more than ten years of experience producing custom industrial wheels and rollers for overseas markets. Our customers include heavy equipment builders, material handling integrators, caster wholesalers and maintenance teams that need reliable replacements fast. Because we control casting, machining, bonding and inspection in one plant, we can offer a complete custom solution from drawing review to shipment, including engineering advice on hardness selection and load safety margins. We work with both small trial orders and long-term wholesale supply agreements, and we ship worldwide.
Factory & Equipment
Our workshop is equipped for the full production chain of large diameter polyurethane wheels, which keeps lead times short and quality consistent from batch to batch.
- CNC lathes and milling machines for hub machining and bore tolerances.
- Polyurethane casting and curing ovens with controlled temperature curves.
- Surface preparation and bonding stations for strong hub-to-tread adhesion.
- Dynamic balancing equipment for high-speed wheel assemblies.
- Inspection area with durometer, hardness testers and load test rigs.
Certifications and Quality Control
Quality control runs at every stage rather than only at final inspection. Incoming steel is checked for grade and hardness, hubs are measured after machining, and finished wheels are tested for hardness, dimensions and bond integrity. Our factory operates under ISO 9001 quality management, and products can be supplied with material certificates, inspection reports and third-party testing arranged on request. If your project requires RoHS compliance or specific documentation for customs clearance, let us know at the inquiry stage and we will confirm what can be provided.

Frequently Asked Questions
Can you manufacture custom large diameter polyurethane wheels to our own drawing?
Yes. Send us a drawing, a 3D model or a worn sample, and we will confirm the hub material, bore tolerance, tread hardness and bonding method. Our goal is to deliver a custom large diameter polyurethane wheel that fits your equipment the first time, without on-site rework.
What is the minimum order quantity for a customized wheel?
For trial and sample orders we can start from one or two pieces so you can test performance before committing to volume. Wholesale and repeat production orders are quoted separately, with better unit pricing as quantity increases.
How do you choose the right polyurethane hardness for a high-load application?
Hardness is matched to load per wheel, wheel diameter, travel speed and floor type. As a general guide, Shore A 85 works well for medium loads and quiet operation, while higher hardness or Shore D grades suit heavy static loads and steel floors. Tell us your load per wheel and duty cycle and we will recommend a grade, then send a test wheel so you can verify it under real conditions.
What is your typical production lead time?
Standard sizes usually ship within two to four weeks after order confirmation, and fully customized wheels with new moulds or special compounds may take longer. Raw material supply, casting schedules and peak seasons can affect the actual date, so we confirm the schedule in writing before production starts.
Which payment methods do you accept?
We normally accept T/T bank transfer and L/C for larger orders. Other arrangements can be discussed for long-term cooperation, and full details including beneficiary information are provided on the proforma invoice.
How are the wheels packed and shipped?
Wheels are packed on export pallets or in wooden cases, with machined bores protected against rust. We ship by sea, air or express courier depending on your deadline, and we can work with your own freight forwarder if you prefer.
Can these large diameter polyurethane wheels replace the wheels on our existing heavy equipment?
In most cases yes, provided the axle diameter, mounting pattern and load rating match. We can produce a replacement wheel with the same hub interface as your original part, so no modification to the equipment is needed. If you are unsure, send photos and dimensions and we will confirm compatibility.
Do you offer wholesale pricing and volume supply for repeat orders?
Yes. As a manufacturer working directly with overseas buyers, we quote wholesale pricing for repeat and volume orders and can hold a consistent specification across batches. Share your annual quantity and delivery pattern and we will prepare a tailored price suggestion.
Do you offer warranty and after-sales support?
We provide a twelve-month warranty against manufacturing defects such as bonding failure, incorrect hardness or dimensional deviation from the approved drawing. Wear from normal service is not covered, but if a problem appears we will investigate the batch records and work with you on a replacement or an adjusted specification.
