Description
Custom ESD-Safe Polyurethane Wheels for Electronics Assembly
These custom ESD-safe polyurethane wheels are engineered for electronics assembly lines, where an unnoticed static discharge can quietly damage boards, sensors and connectors. As a professional China factory, manufacturer and supplier, we treat every wheel as a made-to-order solution: you define the diameter, tread width, hub material, bearing type and target surface resistance, and our engineering team formulates the polyurethane compound to match your equipment. The ESD-modified elastomer holds surface resistance inside the 10^6 to 10^9 ohm range while keeping hardness and abrasion resistance stable, so trolleys, conveyor fixtures and automated guided vehicles keep moving without charging the parts they carry. Each batch leaves our own plant under ISO 9001 quality procedures, is verified with a surface resistance meter and a runout gauge, and is packed for wholesale export — which is why buyers who compare us with other suppliers usually stay for the price and the reliability behind it. Whether you need a single trial set or a scheduled custom OEM program, our team can offer expert advice and a price suggestion for your specific market.
Why Choose Our ESD-Safe Polyurethane Wheels
Electronics assembly is a low-tolerance environment in more ways than one. A wheel that tracks poorly throws the fixture off position; a wheel that holds a charge turns a routine transfer into a returned board. We design both problems out at the same time, so the wheel your process engineers install is one they do not have to think about again.
The ESD-modified polyurethane compound is formulated in-house, which lets us tune hardness, rebound and surface resistance together instead of buying a compromise compound from an outside supplier. Machined hubs in aluminum alloy, steel or engineering plastic let you match the load rating and the weight budget of your assembly fixture. Diameter tolerance and radial runout are controlled on the finished wheel rather than on the mould alone, reducing vibration on high-speed conveyor lines. OEM and ODM custom projects are welcome: send us a drawing, a sample or simply the load, speed and static requirement, and we will return a proposal with expert advice and a price suggestion for your market.
Typical applications: electronics assembly lines, ESD-protected trolleys and carts, conveyor fixtures, automated guided vehicles, SMT handling systems, cleanroom transfer stations, and component sorting equipment.
As a China-based factory and OEM/ODM supplier, we provide customizable ESD-safe polyurethane wheels with your choice of hardness, hub material (steel / aluminum / engineering plastic) and mounting dimensions. Wholesale orders and customized samples are welcome for global electronics assembly projects.

Material Properties – ESD-Modified Polyurethane Elastomer
The values below describe the ESD-modified polyurethane elastomer we use as standard. Hardness and surface resistance can be shifted within the stated bands, but the trade-off between rolling comfort, load capacity and wear life is always discussed with you before we commit to a formulation.
| Property | Specification | What It Means in Use |
|---|---|---|
| Base polymer | ESD-modified polyurethane elastomer | Dissipates static charge while keeping the mechanical strength of standard PU |
| Hardness | Shore A 85 typical, 70 to 95 available | Softer grades protect delicate surfaces, harder grades carry heavier fixtures |
| Tensile strength | ≥ 35 MPa | Resists tearing when wheels run over floor joints and cable covers |
| Tear strength | ≥ 60 kN/m | Longer service life on lines with frequent start and stop cycles |
| Abrasion loss | ≤ 60 mm³, DIN 53516 | Slower tread wear means fewer wheel changes and less downtime |
| Compression set | ≤ 15% | Keeps the wheel round after continuous static loading |
| Surface resistance | 10^6 to 10^9 ohms | Stays inside the ESD-dissipative band, protecting sensitive components |
| Temperature range | -20°C to +80°C | Covers typical assembly halls and climate-controlled workshops |

About Us – China OEM/ODM Manufacturer for ESD Polyurethane Wheels
We are a top China-based polyurethane wheel manufacturer and supplier serving electronics, automation and material handling customers worldwide. Our factory concentrates on cast and machined PU wheels, with the ESD series developed specifically for customers who need static control and mechanical precision in the same component. Orders from a single trial set to scheduled wholesale volumes move through the same process: drawing review, compound selection, casting, machining, inspection and export packing. That structure is deliberate — it lets us give a small project the attention of a large one, and it keeps the price predictable when volumes grow. OEM, ODM and OBM requests are all handled by the same engineering team. Customers from Europe, North America and Southeast Asia visit our plant each year to review production, witness testing and discuss new wheel projects face to face. We welcome factory visits and can arrange sample runs, compound discussions and quality review sessions during your stay. Video plant tours and live online inspections are also arranged for buyers who cannot travel.

Frequently Asked Questions – ESD-Safe Polyurethane Wheels
1. Can these wheels be customized to our own assembly equipment?
Yes. Almost every order we ship is a custom build rather than a catalogue item. You can specify wheel diameter, tread width, tread profile, hub material, bore and bearing type, hardness and surface resistance target. Send a drawing, a worn sample or simply the load and speed data, and we will come back with a practical solution and expert advice on the best configuration for your equipment.
2. How do you control the ESD performance of these polyurethane wheels?
Static control is designed into the compound rather than applied as a surface coating, so the ESD-dissipative behaviour survives normal wear. We formulate each batch to a target surface resistance between 10^6 and 10^9 ohms, then verify it with a surface resistance meter before the wheels leave the factory. Hardness and abrasion resistance are checked on the same batch, which is why our custom ESD-safe polyurethane wheels for electronics assembly hold their electrical and mechanical properties together over time.
3. What is the minimum order quantity for custom ESD wheels?
Our standard minimum is 50 pieces per size. For a first trial or a prototype line, we can discuss smaller quantities so you can test the wheel in your own process before committing to a wholesale order.
4. What is the typical lead time?
Production usually takes 10 to 20 working days after the drawing and sample are approved. Lead time depends on material supply, machining schedule and current order volume, so we confirm a specific date with you at the time of order and update you if anything shifts.
5. Can I get samples before placing a volume order?
Samples are available and are strongly recommended for electronics assembly applications, where small differences in hardness or tread profile can change how the fixture behaves. Sample cost and freight are discussed individually and can often be credited against the first volume order.
6. How are the wheels packed for shipping?
Wheels are packed in inner cartons and stacked on export pallets, with moisture protection and reinforced edges for sea freight. For sensitive surfaces we can add separators between wheels, and we can print your own labels and carton markings for OEM shipments.
7. Which payment and shipping terms do you support?
We normally work with T/T and can discuss other terms for long-term partners. Shipments go by air, sea or express courier depending on volume and urgency, and we handle export documentation including packing list, commercial invoice and certificates of origin where required.
8. Do you provide a warranty on custom wheels?
We stand behind our workmanship and material. If a wheel fails to meet the agreed specification, we will investigate the batch, share the test records and provide a suitable replacement or corrective solution. Warranty terms are confirmed in the order documents so both sides know exactly what is covered.
9. How do you keep wholesale pricing competitive for larger orders?
As a direct China factory, we price on quantity and material selection rather than through trading layers. For volume orders of 200+ pieces we can usually arrange a tailored quotation and a fixed production window. Please share your annual usage and target price so we can advise on the most practical solution for your market.
10. Can you add anti-static wheels to an existing conveyor or AGV design?
In most cases, yes. Send us the current hub or axle drawing, the load per wheel and the expected speed, and our engineers will confirm whether our standard ESD polyurethane wheel family can be adapted or whether a new hub design is needed. Mounting dimensions, bearing seats and shaft fits can all be customized to match your existing equipment.
