Description
Custom Threaded Axle Polyurethane Wheels for Conveyor Rollers – China OEM/ODM Manufacturer for 50–800 kg Heavy-Duty Conveyor Lines
Our custom threaded axle polyurethane wheels for conveyor rollers start with a machined steel or aluminium core that is sandblasted, primed, and then chemically bonded to a high-performance cast polyurethane tread, finished with a precision-cut threaded axle that threads straight onto your existing conveyor shaft. Compared with rubber, nylon, or plain steel rollers, the polyurethane tread holds its shape under continuous load, resists abrasion, oil, and moisture, and runs noticeably quieter with less vibration, so conveyor lines track straighter and maintenance intervals stretch further. As a China factory manufacturer with more than a decade of export experience, we build every wheel to your drawing — axle thread, diameter, tread width, durometer, colour, and load rating — letting one specification cover an entire conveyor fleet instead of mixing mismatched parts from scattered suppliers. Every batch ships with dimensional inspection records, tread hardness readings, and core-to-tread bonding test results, and full OEM and ODM customization is available from prototype through volume production, with wholesale pricing straight from our factory.
Why Choose Our Threaded Axle Polyurethane Wheels
The threaded axle is the detail that separates these wheels from generic press-fit rollers. Nothing needs to be re-machined, welded, or adapted on site: the wheel threads onto an existing conveyor shaft and locks into position, which shortens changeover time and reduces the risk of misalignment during installation. Buyers who run mixed fleets appreciate that a single specification can cover an entire conveyor line instead of chasing matching parts from scattered suppliers.
Because the tread is chemically bonded rather than mechanically pressed, the polyurethane will not slip or peel off the core under shock loading, which is the most common failure point on low-cost replacement rollers. Threads are cut to order in metric or imperial, right-hand or left-hand, and hardness is tunable from Shore A 70 to 98: softer treads grip and damp noise on light packaging lines, while harder treads carry heavier loads and resist cutting in abrasive or scrap-heavy environments. Low rolling resistance further cuts motor load on long or multi-drive runs, and every production lot is measured and logged for diameter, width, run-out, and hardness so a reorder performs like the original.

Material Properties – 90 Shore A Conveyor-Grade Polyurethane
The table below lists the typical mechanical and chemical properties of our standard 90 Shore A conveyor-grade polyurethane compound for threaded axle wheels. Product photographs and dimensional drawings are issued with every quotation so you can verify the geometry before committing to a production order. The standard documentation set covers a side view showing the threaded axle and thread pitch, a cross-section showing tread thickness and core bonding, a close-up of the bonding interface, a mounted view on a conveyor roller assembly, and the final packing configuration. If your project needs a specific view for internal approval, tell us and we will photograph the sample accordingly.
| Property | Test Method | Typical Result |
|---|---|---|
| Abrasion resistance | DIN 53516 | ≤ 60 mm³ loss |
| Tensile strength | ISO 37 | ≥ 35 MPa |
| Tear strength | ISO 34-1 | ≥ 50 kN/m |
| Hardness | ISO 868 | 90 ± 3 Shore A |
| Compression set | ISO 815 | ≤ 20 % |
| Rebound resilience | ISO 4662 | ≥ 40 % |
| Oil and grease resistance | ASTM D471 | Low swelling |
| Core-to-tread bonding | Internal peel test | No separation after test |
The figures above are typical laboratory results for our standard 90 Shore A conveyor-grade polyurethane compound, provided as guidance for engineering evaluation; final values are confirmed against the approved sample or drawing before production begins. Higher hardness grades trade some elasticity for greater load capacity and cut resistance, while lower hardness grades improve grip and reduce noise. Custom hardness from Shore 70A to 98A is available at our factory.

Factory & Equipment
Our Factory Workshop with Professional Equipment for Threaded Axle Polyurethane Wheel Manufacturing
Our workshop covers casting, CNC machining, bonding, finishing, and inspection under one roof. Casting lines handle polyurethane from Shore A 70 to 98 with controlled curing, CNC lathes and milling centres produce the threaded axles and cores to drawing, and dedicated bonding stations manage surface preparation and cure schedules so the tread-to-core interface stays reliable. Inspection equipment includes hardness testers, callipers and micrometers, run-out gauges, and a tensile and peel testing bench. Keeping these processes together means we can adjust a thread pitch or durometer without waiting on an outside subcontractor.
Quality Control and Certifications
Quality is checked at four points rather than only at final inspection: incoming raw material verification, core machining measurement, tread casting and bonding inspection, and finished-product dimensional and hardness testing. Incoming polyurethane batches are checked for hardness and appearance, cores are measured for concentricity before bonding, and every finished lot is sampled for radial run-out and load behaviour. Production runs under an ISO 9001 certified quality system, and material certificates and inspection reports can be supplied with bulk shipments for your own incoming quality records.
Production and Inventory Policy
Lead time: Actual lead time varies with raw material supply, machining capacity, and peak-season workload, so a reasonable fluctuation should be expected. We provide the most accurate delivery estimate we can once the order is confirmed and keep you informed of any change as the batch progresses.
Stock status: We generally do not hold stock, although a limited range of fast-moving standard sizes is kept on hand. Those quantities change continuously with sales and production, so please contact us to confirm live availability before placing an order against stock.
Bulk and urgent orders: For large-volume or time-critical requirements, please talk to us early about capacity and scheduling. We will do our best to fit your timeline and will be upfront if a date cannot be met.
Frequently Asked Questions – Threaded Axle Polyurethane Wheels
1. What wheel sizes and axle threads can you customize?
We produce custom threaded axle polyurethane wheels from 50 mm to 250 mm in diameter, with tread widths from 20 mm to 80 mm, and cut the axle thread to your metric or imperial specification in either right-hand or left-hand direction. Send a drawing, a worn sample, or even a photo with dimensions, and our engineers will confirm feasibility and the most economical configuration before quoting.
2. How do I choose the right polyurethane hardness for my conveyor application?
As a general starting point, Shore A 85–90 suits most general conveyor rollers, Shore A 95–98 suits high-load or abrasive conditions where cut resistance matters more than grip, and Shore A 70–80 suits light packaging lines where noise reduction and surface protection are the priority. Tell us your load per wheel, line speed, and the material being conveyed, and we will give you a professional recommendation rather than leaving you to guess.
3. Can these threaded axle wheels replace standard rubber or nylon rollers?
In most cases yes, provided the shaft thread and mounting dimensions match. Polyurethane typically outperforms rubber in abrasion and oil resistance, and outperforms nylon in impact absorption and noise, so it is often the better long-term choice for conveyor rollers that see continuous running or washdown conditions. We can review your current part against our drawing and confirm the fit before you commit, and where the shaft thread or mounting dimensions differ we will quote a custom solution built to your drawing.
4. What is your minimum order quantity, and can I buy samples first?
Standard specifications start at 100 pieces per size. For a new design we can usually supply a small prototype or sample quantity first so you can test the wheel on your own conveyor before placing a volume order. Sample lead time and cost are quoted case by case depending on whether new tooling or cores are required.
5. How long is production, and how do you handle urgent orders?
Typical production runs take roughly 15 to 30 days after drawing approval and deposit, depending on material availability and current shop load. Because that window can shift during peak seasons, we confirm a realistic schedule at order stage and flag any change early. For urgent requirements, contact us before ordering — we will check capacity and tell you honestly what can be achieved.
6. How do you control quality, and what certifications do you hold?
Production runs under an ISO 9001 certified quality system with checks at incoming material, core machining, bonding, and final inspection. Each finished lot is sampled for diameter, width, radial run-out, and tread hardness, and core-to-tread bonding is verified by peel testing. Inspection reports and material certificates can be issued with bulk shipments.
7. Do you support OEM, ODM, and private-label manufacturing?
Yes. We support OEM production to your drawing, ODM development where our engineers propose the geometry and compound, and OBM with your own branding and packaging. Custom colours, laser-marked part numbers, and branded cartons are all available for qualified volumes.
8. How are the wheels packed and shipped?
Wheels are packed in cartons with inner separators to protect the tread and threaded axle, then palletised or loaded into crates for sea freight. Air and express options are available for samples and urgent shipments. Let us know your receiving requirements, such as pallet size, labelling, or moisture protection, and we will pack accordingly.
