Description
Custom Non Marking Silicone Coated Wheels Smooth Conveyor Roller
Why Choose This Product
Whether you are upgrading an existing conveyor line or developing a new automated system, these custom silicone coated wheels give you a dependable, low-maintenance conveying surface with a clean, non-marking contact face.
- Non-marking silicone surface — the coating leaves no visible marks on belts, floors, or packaged goods, making it a strong choice for food, pharmaceutical, electronics, and cleanroom conveyor applications.
- Smooth and quiet running — each roller is finished to Ra ≤ 1.6μm and dynamically balanced to ≤0.05mm, which lowers vibration, noise, and bearing stress during continuous operation.
- Strong core with less weight — steel, aluminum, and nylon core options are machined to your drawing, so you can balance load capacity and overall weight for your specific conveyor design.
- Proven coating adhesion — a primer-based, heat-cured bonding process prevents peeling or separation between the silicone and core, verified under a 5,000-hour continuous load trial.
- Fully customized dimensions — diameter, width, hardness, color, bore size, groove profile, and keyway can be adapted to your application. Custom wheels are available for OEM replacement parts and new equipment projects.
Typical applications: Belt conveyors, roller conveyors, automated guided vehicles (AGVs), packaging lines, cleanroom stations, food processing equipment, electronics assembly lines, and general material handling systems where clean contact and low wear are required.

Material Properties
The non-marking silicone compound is chosen for conveyor environments that demand clean contact, stable friction, and long service life. Typical values are shown below.
| Property | Typical Value |
|---|---|
| Hardness | 30–70 Shore A (custom) |
| Tensile Strength | ≥ 8 MPa |
| Elongation at Break | ≥ 400% |
| Tear Resistance | ≥ 20 N/mm |
| Abrasion Loss (DIN 53516) | ≤ 120 mm³ |
| Surface Friction | 0.4–0.8 dry, adjustable by formulation |
| Heat Resistance | Continuous 120 °C, peak 150 °C |
| Cold Flexibility | Retains flexibility at -20 °C |
| Chemical Resistance | Good resistance to oils, mild acids, and cleaning agents |
| Food-Grade Option | FDA-conformant silicone grades available |
Typical lab values are shown for guidance; actual performance depends on the selected compound formulation and operating conditions. Custom hardness, color, and surface finish are available from our China factory. For conveyor applications that require higher load capacity and abrasion resistance, we can also recommend polyurethane or rubber-coated alternatives.
About ZHXPRECI – China OEM/ODM Factory
About Us

Customers Visiting

As a China‑based manufacturer and OEM/ODM supplier of industrial wheels, conveyor rollers, and custom silicone components since 2012, ZHXPRECI serves clients in more than 30 countries. We offer customization — from wheel hardness (Shore A 30°~70°) to core materials, colors, and mounting features. Our products are tested to meet ISO9001 standards, supporting reliable performance for your conveyor and automated production lines. Wholesale orders are welcome with competitive direct pricing.
Factory & Equipment
Our production base in China is equipped with automatic mixing and dispensing lines, heat-curing ovens, CNC lathes, and complete testing instruments for hardness, abrasion, adhesion, and dynamic balancing. Each custom silicone coated wheel is inspected at multiple checkpoints before packing. We welcome customer visits and third-party factory audits, and we can arrange a factory tour if you are planning a sourcing trip to China. For remote buyers, production photos and video reports at each manufacturing stage are available.






Our Certifications (ISO9001, RoHS, Testing Reports)
Quality is managed under ISO9001 principles across our manufacturing processes. For specific projects, we can provide RoHS and REACH declarations for the silicone coating materials, as well as FDA-compliant material options for food-contact applications. Test reports and product certificates are issued with each batch upon request.

Production & Inventory Policy
Lead time: Actual delivery time depends on raw material supply, machining schedules, and seasonal order pressure, so a reasonable variance should always be expected. We provide the most accurate delivery estimate after your order is confirmed and keep you informed during production.
Stock status: We normally produce to order rather than maintaining large inventory, although a selection of popular standard sizes is sometimes in stock. Since stock levels change quickly with sales and production, please confirm real-time availability with our sales team before ordering.
Bulk & urgent orders: For large-volume orders or urgent requirements, please contact us in advance to discuss production capacity and scheduling. We will do our best to match your timeline.
Frequently Asked Questions
1. Can you customize the diameter, width, and hardness for our conveyor system?
Yes. Since these custom non-marking silicone coated wheels are designed as a smooth conveyor roller, we can adjust diameter, width, core material, hardness, and bore size to match your frame and load conditions. Our engineers will provide expert advice on the best silicone formulation for your specific application.
2. What is the minimum order quantity?
MOQ depends on the model and coating formula. For standard sizes, MOQ is typically 100 pieces; for fully custom dimensions, it may be higher depending on tooling and material preparation. Please contact us with your target quantity and we will give you a clear answer.
3. Why choose silicone coating instead of rubber or polyurethane?
Silicone provides a non-marking, low-friction surface that keeps belts and products clean, which is especially important in food, pharmaceutical, electronics, and cleanroom lines. It also performs consistently across a wide temperature range from -20 °C to +120 °C and resists aging and ozone better than standard rubber.
4. How does the silicone layer stay bonded to the metal core under heavy loads?
We use a specialized primer and heat-cured bonding process that creates both a chemical and mechanical bond between the silicone and the core. This process is validated through a 5,000-hour continuous load endurance test, so peeling or separation should not occur under normal operating conditions.
5. Can these wheels be used in cleanroom or AGV applications?
Yes. The non-marking silicone surface, low noise level, and controlled dynamic balancing make this smooth conveyor roller series suitable for cleanrooms, electronic assembly lines, and automated guided vehicles where floor marking, dust, and vibration must be minimized.
6. What are your payment and delivery terms for export orders?
We commonly accept T/T, L/C, and PayPal for samples. Delivery time is usually 15 to 30 days after deposit for standard products, while custom projects may need additional scheduling. We will confirm the exact lead time and the best shipping method (sea, air, or express) based on your order volume and destination.
7. Do you provide samples for testing?
Yes. After technical confirmation, we provide samples for evaluation. The sample cost is quoted separately and can be deducted from the invoice for volume orders. We can also arrange pre-shipment inspection and third-party testing if your project requires additional assurance.
8. What warranty do you offer on custom silicone coated wheels?
Standard warranty is 180 days from shipment date against manufacturing defects. Extended warranty (12 months) is available for bulk orders. Normal wear and tear or improper installation is not covered. We stand behind our workmanship and materials.
