Description
Custom Non-Marking Silicone Coated Wheels & Smooth Conveyor Roller
Our custom non-marking silicone coated wheels are engineered as smooth conveyor rollers for bottle filling lines, carton transfer conveyors, glass handling equipment, automotive parts assembly, and cleanroom packaging stations. The silicone coating creates a soft yet durable contact surface that prevents scuffs and marks on painted, glass, or plastic goods, while the steel or aluminum core maintains stable load capacity over long operating shifts. Every roller is tested for concentricity and rotation smoothness, reducing noise, downtime, and maintenance costs in your material handling operation. As a professional manufacturer and supplier in China, we offer these rollers for sale at competitive wholesale pricing, with full OEM/ODM customization in diameter, shaft end, hardness, and color, plus expert advice to match your market demand. Dimensional drawings, coating cross-section photos, and application videos are available upon request, so you can evaluate the noise level and marking behavior before ordering.
Why choose our non-marking silicone conveyor rollers?
This roller is designed for applications where surface preservation and smooth product handling matter most. The non-marking silicone layer uses an exclusive compound that resists scuffing and leaves no residue on sensitive surfaces such as powder-coated metal, glass panels, and printed cartons. Compared with standard rubber rollers, our silicone coating provides a higher friction coefficient for reliable transmission while remaining gentle on goods. This advantage helps customers reduce product rejects and packaging rework, a direct saving that many conveyor operators appreciate. We validate these claims through in-house rotation tests and hardness measurements on every production batch, and our factory follows ISO9001 quality management procedures.

| Compound | Shore A Range | Abrasion Resistance | Oil Resistance | Load Capacity |
|---|---|---|---|---|
| Polyurethane (PU) | 20-98 A | Excellent ★★★★★ | Good | Excellent |
| Natural Rubber (NR) | 25-98 A | Excellent ★★★★★ | Poor | Excellent |
| Nitrile (NBR) | 20-95 A | Good ★★★ | Excellent | Good |

From the comparison, silicone offers superior temperature flexibility and non-marking properties, making it the best choice for clean-room or temperature-sensitive conveyor environments. Our silicone compound leaves no scuff or black marks on inspected surfaces, provides a stable dry friction range of 0.5–0.7 for reliable conveying, and absorbs vibration to reduce running noise. While polyurethane remains the top choice for high-abrasion and heavy-load applications, our non-marking silicone-coated rollers are abrasion-tested in-house and deliver extended service life in light-contact applications. We can recommend the optimal material based on your working conditions as part of our expert custom solution.
About Us
We are a China-based manufacturer specializing in conveyor rollers and custom wheel solutions since 2010. Our engineering team works directly with importers, distributors, and equipment brands to develop rollers for demanding production environments. Our management and production processes follow ISO9001 quality standards, and the silicone coating material is RoHS compliant, with material declarations available for food-contact or cleanroom projects when requested. With export experience to more than 30 countries, we understand the importance of stable quality, clear communication, and reliable supply. We act as a top OEM/ODM partner, not just a supplier, and we are glad to offer expert advice during the selection and prototyping stage.
Factory & Equipment
Our workshop is equipped with computer-controlled turning machines, coating curing lines, dynamic balancing equipment, and in-house testing stations. This allows us to control every step from tube cutting and shaft machining to coating application and final inspection. Before shipment, each batch is measured for outer diameter tolerance, concentricity, hardness, and surface finish to make sure the rollers meet the agreed specification. Customers from many countries have visited our factory for audits and joint testing; you are welcome to arrange a visit before placing a batch order.
Production & Inventory Policy
Lead time: We do our best to offer an accurate delivery estimate after order confirmation. Actual lead time may vary reasonably depending on raw material supply, machine scheduling, and peak season workload. We will keep you informed if any adjustment is needed.
Stock status: We normally work on a production-to-order basis, although some popular standard sizes are kept in stock. Stock quantities change dynamically with sales and production, so we suggest confirming real-time availability with our team before you place an order.
Bulk & urgent orders: If you have a large order or an urgent requirement, please contact us early to discuss capacity and production scheduling. We will try our best to coordinate with your timeline.
Frequently Asked Questions
Can you custom produce this silicone coated roller for our existing conveyor line?
Yes. We offer full custom solutions for outer diameter, roller length, shaft style, color, and hardness. Send us your drawing, sample, or target performance parameter, and our engineers will provide a matching recommendation with a clear quotation.
What hardness do you recommend for high-load conveyor applications?
For heavy loads, we generally recommend a core of carbon steel or stainless steel with a silicone hardness around 60 Shore A. This combination provides sufficient cushioning for quiet operation while maintaining dimensional stability under continuous pressure. For loads above 300 kg per roller, we may suggest a thicker steel tube and a shorter support span.
Will this roller leave marks on powder-coated or glass surfaces?
No. The non-marking silicone formula is specifically developed to avoid scuffs, black streaks, and residue on sensitive surfaces. We can provide test samples so you can verify this under your actual production conditions.
What is the MOQ for a custom order?
The MOQ depends on the complexity of the roller. For standard diameters and lengths, we accept small trial orders starting around 20 pieces. For fully custom shafts or special coating colors, a slightly higher quantity may apply. We are flexible in supporting new projects.
How do you handle quality control before delivery?
Every production batch is inspected for diameter tolerance, roundness, coating adhesion, hardness, and rotation smoothness. We keep inspection records by batch number and can provide photos or third-party inspection support according to your request.
What payment and shipping methods do you accept?
We commonly accept T/T, L/C, and PayPal for sample or trial orders. Shipment can be arranged by sea freight, air freight, or express courier depending on quantity and urgency. For regular orders we will suggest the most economical delivery option based on your destination.
