Description
Custom Non-Marking Silicone Coated Wheels and Smooth Conveyor Rollers
As a top manufacturer and supplier in China, we specialize in custom non-marking silicone coated wheels and smooth conveyor rollers built for applications that demand clean contact, gentle surface handling, and quiet operation. The silicone coating is formulated to leave no marks on painted floors, packaging materials, or finished goods, which makes these wheels ideal for food packaging lines, electronics assembly conveyors, pharmaceutical filling systems, and automated material handling equipment. Our factory supports OEM and ODM customization, allowing you to specify core material, roller dimensions, coating hardness, color, and shaft configuration. These custom non-marking silicone coated wheels and smooth conveyor rollers are available for sale in both small trial quantities and wholesale volumes. We back every order with ISO9001-certified processes, export experience across Europe, America, and Southeast Asia, and a professional custom solution that balances performance with competitive price. Send us your drawings or samples for expert advice and a direct price suggestion based on your market demand.
Why Choose This Product
Standard rubber or polyurethane coated rollers often leave dark marks on floors and product surfaces, creating extra cleaning and rework cost in sensitive production areas. Our silicone coated wheel uses a low-surface-energy compound that resists smearing and staining, keeping the conveyor line clean without additional maintenance. The silicone layer also provides excellent high-temperature resistance and low noise operation, which is a clear advantage over conventional coatings for continuous production processes. The direct benefit is fewer roller replacements, less downtime, and a cleaner final product for your customers. Every batch is tested for coating adhesion, hardness consistency, and dimensional accuracy, and we can share the test report as evidence before shipping.

Material Properties Reference
| Material / Item | Property Description |
|---|---|
| Silicone Coating | Non-marking, high-temperature resistant, low odor, low friction, and available with FDA-compliant raw material certification for food-contact applications. |
| Steel Core | High load capacity and excellent dimensional stability for heavy-duty conveyor rollers and wheel sets. |
| Aluminum Core | Lightweight, corrosion resistant, suitable for high-speed or indexing conveyors where reduced inertia matters. |
| Abrasion Resistance | Coated surface is tested with ASTM D4060 methodology to ensure low thickness loss under continuous running. |
| Surface Cleanliness | Smooth finish minimizes dust collection and simplifies washdown procedures in hygienic production areas. |
From the comparison, silicone offers superior temperature flexibility and non-marking properties, making it the best choice for extreme-temperature or clean-room environments, while polyurethane remains the top choice for high-abrasion and heavy-load applications. We can recommend the optimal material based on your working conditions.
About Us
We are a China-based factory specializing in precision rollers, wheels, and coated components for conveyor systems, AGV platforms, and industrial automation. Since our founding, we have worked with manufacturers of packaging machinery, sorting equipment, and mobile robots in more than 20 countries. Our engineering team is comfortable with non-standard requests: unusual dimensions, custom coating colors, special shaft designs, and prototype validation. As a professional OEM, ODM, and OBM manufacturer, we keep pricing transparent and communication direct. If a requested feature is not technically suitable for your application, we will tell you honestly and recommend a better alternative.
Factory & Equipment
Our facility is equipped with CNC lathes, automated coating systems, dynamic balancing testers, and a complete inspection station for hardness and surface quality. Every order of custom non-marking silicone coated wheels follows the same routine: incoming material verification, in-process dimension inspection, final visual check, and packing confirmation. Third-party factory audits are welcome, and video inspection can be arranged for overseas clients who cannot visit in person.
Certifications
The factory operates under an ISO9001:2015 quality management system. The silicone compounds used in our smooth conveyor rollers comply with RoHS and REACH requirements. Material declarations, coating test reports, and export documentation are available on request.
Production & Inventory Policy
Lead time: Actual delivery schedules may vary due to raw material supply, machine availability, and seasonal production peaks. We provide the most accurate estimated delivery date after order confirmation and keep you informed throughout the process.
Stock status: We generally produce to order, but a limited quantity of popular standard rollers is sometimes available from stock. Inventory levels change quickly with sales and production, so please contact our sales team to confirm real-time availability before placing an urgent order.
Bulk & urgent orders: For large-volume orders or tight deadlines, we recommend discussing production capacity and scheduling with us in advance. We will make every effort to coordinate with your timeline.
Frequently Asked Questions
Can you customize the hardness, color, and dimensions of the silicone coating?
Yes. We can adjust Shore A hardness from 30° to 70°, provide standard colors such as grey, black, blue, and green, and machine the rollers to your drawing dimensions. OEM and ODM orders are supported, and we can offer engineering advice on the right combination for your specific conveyor line. Our custom non-marking silicone coated wheels and smooth conveyor rollers can be tailored to fit the exact requirements of your material handling equipment.
Why is the roller described as non-marking, and how is this tested?
Our silicone coated wheel uses a low-surface-energy formulation that does not transfer pigment or residue onto floors, packaging, or product surfaces. We verify this with a pressure-contact test on white painted steel and finished concrete, and the result shows no visible marks. This quality is especially valuable for electronics assembly, battery handling, and food processing plants where surface cleanliness is critical.
What are the typical MOQ and delivery time for custom sizes?
For standard sizes, the MOQ is 10 pieces, and for fully customized coating color or hardness, the MOQ is 50 pieces. Delivery is normally 15 to 25 working days for orders from 100 to 500 rollers, depending on the production schedule and raw material availability at the time of booking.
Do you support OEM/ODM and private label packaging?
Yes. As an experienced China factory, we support private label packaging, custom part numbers, and design modifications to the core, coating, and shaft configuration. If you need a tailored solution for your target market, we can provide expert advice on material selection and cost control.
How do you ensure quality before shipping?
Each roller is measured and checked for coating thickness, hardness, concentricity, and surface finish before packing. We can share inspection photos and reports on request. Third-party inspection, such as SGS or TUV, is also acceptable and can be arranged with prior notice.
Can these silicone coated wheels be used in food or cleanroom environments?
Yes, when the food-grade silicone option is selected, the material is suitable for direct or indirect food contact in many regions. The smooth surface is easy to clean and does not absorb odors, making the roller a practical choice for pharmaceutical filling, beverage packaging, and cleanroom conveyor systems.
What is the ordering process and what payment methods do you accept?
We normally confirm the technical specification first, then issue a proforma invoice with the final price and delivery estimate. For sample orders, we accept T/T, PayPal, or Western Union. Larger production orders are usually handled with a 30% deposit and 70% balance before shipment. You are welcome to contact us before ordering to confirm all details.
