Description
Custom Keyway Mounted Polyurethane Wheels for Pump Drives – China OEM/ODM Manufacturer and Supplier
Why Choose Our Keyway Mounted Polyurethane Wheels?
Custom keyway fit. Each wheel is machined to your exact shaft and keyway dimensions, giving a secure, wobble-free mount that protects both the wheel and the drive shaft from premature wear. The result is fewer unexpected stoppages on your pump drive line.
Exclusive polyurethane formula. Our PU compound is formulated for higher tear strength and lower compression set than conventional cast polyurethane, so wheels hold their shape and tread profile longer in demanding pump environments. Compared with standard rubber, the same wheel diameter carries a higher load without flattening, which keeps your pump drive running at a stable speed for longer stretches between service stops.
Core options to match your environment. Steel cores suit high-load industrial drives, stainless steel resists corrosion in wet or chemical exposure, and aluminum cores reduce rotating mass where weight matters for portable or skid-mounted pump units.
Competitive factory pricing. Buying directly from our China production base removes middlemen, so you receive wholesale-level pricing without compromising material grade or workmanship.
Full OEM/ODM support. Send your drawing or a sample, and our engineering team gives expert advice on hardness selection, tolerance stack-up, and cost-effective manufacturing routes for your market.

Material Properties – Performance Data of the Polyurethane Tread
The values below reflect typical test results for our standard polyurethane compounds. Actual figures vary with hardness grade and wall thickness, and we will confirm the suitable compound for your load and speed conditions before production begins.
| Property | Test Method | Typical Value |
|---|---|---|
| Hardness | ASTM D2240 | Shore A 80°–95° |
| Tensile Strength | ASTM D412 | 35–55 MPa |
| Tear Strength | ASTM D624 | 60–110 kN/m |
| Abrasion Loss | DIN 53516 | 25–50 mm³ |
| Compression Set | ASTM D395 | Below 25% |
| Rebound Resilience | ASTM D2632 | 40%–55% |
| Operating Temperature | — | −30 °C to +80 °C |
Higher hardness grades suit high-load, low-speed pump drives where deformation must stay minimal, while softer grades absorb more vibration and noise. Custom hardness from Shore A 80° to 95° and alternative core materials are available from our factory on request. In practice, a 90° Shore A tread on a steel core is often the best compromise for a rotary lobe pump transmission running at moderate speed, while 80°–85° grades tend to serve metering and dosing pumps where vibration isolation matters more than stiffness.
About Us – China OEM/ODM Manufacturer of Custom Polyurethane Wheels
Customers Visiting
We are a China-based manufacturer specialising in custom polyurethane wheels, rollers, and elastomer components for industrial equipment. Since our founding, we have focused on one thing: turning customer drawings into reliable, repeatable parts. Our team combines polymer engineering experience with hands-on machining, so we can advise on hardness, interference fits, and keyway tolerances before a single chip is cut. Over the years we have supplied OEM and ODM customers across Europe, North America, Southeast Asia, and the Middle East, and many of those relationships have lasted more than a decade.
We understand the real concerns that come with sourcing custom parts from overseas: inconsistent quality between batches, unclear communication, and lead times that slip without warning. That is why we assign a dedicated project contact to every order, keep documentation from raw material to final inspection, and follow up after shipment to confirm the parts perform as expected. Whether you need a small trial batch or a recurring production schedule, we treat each order with the same attention to detail. Wholesale and customized orders are welcome with competitive direct pricing.
Factory and Equipment
Our production floor is equipped with CNC lathes, machining centers, keyway broaching machines, and polyurethane casting lines. This in-house capability means we control the critical steps ourselves rather than relying on subcontractors, which helps keep tolerances tight and delivery predictable. Incoming raw materials are checked against specification before release to production, and finished wheels pass dimensional and hardness inspection before packing. For customers who require third-party verification, we welcome SGS, BV, or other inspection arrangements.
Our Certifications (ISO9001, Testing Reports)
Our factory operates under an ISO9001-certified quality management system. Certificates are available on request, and we are happy to support customer-specific compliance requirements where feasible. Material test reports can also be provided for critical pump drive applications.
Production and Inventory Policy
Lead time: Actual lead time is affected by raw material supply, machining capacity, and peak-season workload, so it can vary within a reasonable range. We will provide the most accurate delivery estimate possible once your order is confirmed and keep you informed of any changes.
Stock status: We generally do not hold finished goods inventory, though a limited number of fast-moving standard sizes may be in stock. Available quantities change with ongoing sales and production, so please contact us to confirm real-time availability before placing an order.
Bulk and urgent orders: For large-volume or time-sensitive requirements, please reach out early so we can review capacity and scheduling. We will do our best to align with your timeline.
Frequently Asked Questions – Keyway Mounted Polyurethane Wheels for Pump Drives
What information do you need to quote a custom keyway mounted polyurethane wheel?
Please share the wheel diameter, width, bore size, keyway dimensions, required hardness, core material preference, and expected load. A drawing or sample photo helps us confirm tolerances quickly and give you an accurate price.
How do I choose the right polyurethane hardness for my pump drive?
Harder compounds, around Shore A 90°–95°, are better for high-load, low-speed pump drives where deformation must be minimal. Softer compounds, around Shore A 80°–85°, absorb more vibration and noise, which suits lighter loads and higher speeds. Our engineers can recommend a grade based on your load, speed, and surface conditions.
Can you match the keyway to DIN 6885 or our own drawing?
Yes. We machine keyways to DIN 6885 as standard and also produce to customer-specific drawings. Please include the keyway width, depth, and any tolerance requirements in your inquiry.
What is your minimum order quantity?
Our standard MOQ is 10 pieces per size, but we accept smaller trial orders for new customers who want to verify quality before committing to volume production. Sample lead time is usually shorter than bulk lead time.
How long does production take after order confirmation?
Typical production time is 15–30 days depending on size, quantity, and material availability. For urgent orders, we will review our schedule and advise on the earliest achievable date.
What are the available payment and shipping terms?
We commonly work with T/T, and other terms can be discussed for established customers. Shipping is arranged by sea, air, or courier depending on order size and urgency, and we can ship on FOB, CIF, or DDP terms as agreed.
Do you offer OEM and ODM services?
Yes. We support OEM production to your drawing or brand and ODM development where our team helps refine the design. Custom packaging and labeling are also available for qualified orders.
What warranty do you provide?
We stand behind our workmanship and will address any manufacturing defect covered under our warranty terms. Because performance depends heavily on the application, we recommend discussing operating conditions with us upfront so the correct material and tolerances are selected.
