Description
Custom Fixed Polyurethane Wheels for Industrial Racks
Our custom fixed polyurethane wheels for industrial racks are produced in our own China factory, where every batch is built to your drawing, load rating and mounting pattern rather than pulled from a fixed catalogue. The polyurethane tread is bonded to a reinforced steel, cast iron or aluminum core, which gives the wheel a higher load-bearing capacity and better wear resistance than standard rubber or nylon alternatives. That means your racking and storage trolleys roll more smoothly, run quieter and need fewer replacements, even in continuous daily use inside warehouses and distribution centers. Each wheel is dimensionally checked and load-tested before packing, and our ISO9001-certified line has supported OEM and ODM caster projects for overseas buyers for more than a decade. As a top China manufacturer and supplier, we offer customized fixed polyurethane wheel solutions with professional engineering advice and competitive wholesale pricing for the global market.
Why Choose This Product
Polyurethane is widely preferred for rack casters because it combines the load capacity of a hard material with the quiet, floor-friendly running of a softer one. A fixed, or rigid, design keeps the wheel tracking in a straight line, which is exactly what you need on push-pull racking and storage carts where steering is handled by a swivel caster elsewhere. The practical result is a lower cost of ownership across the life of the rack: fewer wheel changes, less downtime and no scuffed epoxy or concrete flooring.
- Custom manufacturing: diameter, width, bore size, plate mounting and axle type are all made to order, so the wheel fits your existing rack frame without modification.
- Material options: polyurethane hardness from Shore A 85 to 95, combined with steel, cast iron or aluminum cores, matched to your load and running surface.
- Reliable supply: as a China-based manufacturer and supplier, we offer wholesale pricing on volume orders with full OEM and ODM support, including your logo and packaging.
- Quality control: every batch is checked for concentricity, hardness and load capacity, and third-party inspection can be arranged on request.

Product Details
Racking systems differ from project to project, so each polyurethane wheel is produced against a confirmed drawing or a physical sample. We pay particular attention to the bond between the polyurethane tread and the metal core, which is where low-cost casters usually fail: a weak bond leads to tread separation under sustained heavy loads. Our production uses a controlled casting and curing process, and each finished wheel is checked for roundness and concentricity so it rolls without wobble. If you are not yet sure which diameter, hardness or bearing suits your rack, send us the load per wheel and the floor condition, and our engineers will recommend the right configuration.

Material Properties
Choosing the correct polyurethane hardness is the single most important decision for a rack wheel. On heavy static loads over concrete, a harder tread reduces deformation and keeps the rack stable; on delicate flooring or where movement is frequent, a softer tread lowers noise and vibration. Our technical team provides expert advice and price suggestions based on your actual working conditions.
| Property | Value / Performance |
|---|---|
| Hardness | Shore A 85 – 95, selected per application |
| Wear resistance | High; outperforms rubber and nylon in abrasive environments |
| Load capacity | Up to 500 kg per wheel, size dependent |
| Rolling resistance | Low, reducing operator effort |
| Noise level | Lower than hard nylon or steel wheels |
| Floor protection | Non-marking; protects epoxy and concrete surfaces |
| Chemical resistance | Good resistance to oils, greases and mild solvents |
| Temperature range | -20 °C to +80 °C |
About Us – China OEM/ODM Factory for Custom Polyurethane Wheels
Factory Overview
Customers Visiting
We are a China-based manufacturer and supplier of custom polyurethane wheels and industrial casters, serving warehouse, logistics and material handling customers worldwide. Our factory concentrates on OEM and ODM projects, which means we build to your specification instead of pushing a fixed catalogue. Over the past ten years we have worked with buyers across Europe, North America and Southeast Asia on rack casters, trolley wheels and heavy-duty rollers, and we welcome customer visits and factory audits at any time. As a professional OEM/ODM partner, we provide expert advice and price suggestions to match your specific market demands.
Factory & Equipment
Our workshop is equipped with CNC machining centers, polyurethane casting and injection equipment, precision grinding machines, and assembly lines for bearings and mounting plates. Incoming steel and polyurethane raw materials are inspected before production, and finished wheels pass a dimensional check plus a dynamic load test. For larger projects we can arrange third-party inspection before shipment, and our engineers are available to review your drawings and suggest cost-effective alternatives when a design can be simplified without losing performance.
Certifications
Our quality management system follows ISO9001 standards and covers incoming material inspection, in-process control and final testing. Test reports and material certificates can be supplied with bulk orders, and RoHS-compliant polyurethane grades are available on request. These documents give overseas buyers and their quality teams the evidence they need to approve a new supplier with confidence.
Production & Inventory Policy
Lead time: Actual lead time can vary with raw material supply, machine scheduling and peak-season workload. We provide the most accurate delivery estimate we can after order confirmation and keep you updated throughout production.
Stock status: We do not hold stock as a rule, although a limited number of fast-moving standard sizes are kept on hand. Real stock levels change constantly with sales and production, so please contact us to confirm availability before placing your order.
Bulk & urgent orders: For large volumes or urgent requirements, please talk to us in advance about capacity and scheduling. We will do our best to accommodate your timeline.
Frequently Asked Questions
Can you manufacture these custom fixed polyurethane wheels for industrial racks to my own drawing?
Yes. Custom manufacturing is our main business. Send us a drawing or a physical sample with the wheel diameter, width, bore size, load rating and mounting plate dimensions, and we will confirm feasibility, tooling requirements and price. Our engineers will also point out any dimension that could cause problems in production before we start.
What is your minimum order quantity?
For standard sizes the MOQ is usually 100 pieces per size. For fully customized wheels with new tooling, the MOQ depends on the design and the mold cost, and we are happy to quote both options so you can compare.
How long is the delivery time?
Typical production takes 15 to 25 days after order confirmation, depending on quantity and whether new tooling is needed. Lead time can shift with raw material supply and peak-season workload, so we always confirm the schedule with you before production begins.
Do you offer OEM and ODM service?
Yes. We support OEM and ODM projects, including your logo, custom packaging and private-label documentation. As a professional manufacturer in China, we regularly act as the behind-the-scenes production partner for caster brands and distributors.
How do you control the quality of each batch?
Raw materials are inspected on arrival, the polyurethane-to-core bond is controlled through a fixed casting and curing process, and finished wheels are checked for hardness, concentricity and load capacity. Third-party inspection can be arranged before shipment if your quality team requires it.
What is the difference between your polyurethane wheels and standard rubber wheels?
Polyurethane offers noticeably higher load capacity and better abrasion resistance than rubber at the same wheel size, while still running quietly and without marking floors. For racking systems that carry heavy static loads, that combination usually means a longer service life and fewer replacements.
Which polyurethane hardness should I choose for my rack?
As a rule of thumb, Shore A 90 to 95 suits heavy static loads on concrete, while Shore A 85 to 90 is a better match for frequent movement and sensitive flooring. Tell us the load per wheel and the floor type, and our technical team will give you a specific recommendation.
What payment and shipping terms do you accept?
We normally work with T/T and can discuss other terms for long-term partners. Shipments are arranged by sea, air or express courier depending on volume and urgency, and we can quote FOB, CIF or door-to-door options so you can compare the total landed cost.
