Description
Custom Non-Marking Silicone Coated Wheels Smooth Conveyor Roller
Our custom non-marking silicone coated wheels smooth conveyor roller is engineered for production lines where surface protection and consistent running matter most. As a professional China factory and OEM/ODM manufacturer, we combine a precision-machined steel core with a specially formulated silicone outer layer to deliver a clean, quiet, and durable conveying component. The silicone coating leaves no marks or residue on painted panels, glass, or packed goods, while its high rebound elasticity reduces vibration and protects fragile surfaces during transport. Each roller is available in custom diameters from 38 mm to 200 mm, lengths up to 3000 mm, and hardness from Shore A 40 to 70, so you can match the exact grip and durability your line requires. With ISO9001-based quality control, 100% dimensional inspection before shipment, and competitive wholesale pricing, we offer a top custom solution that has been trusted by equipment builders across packaging, material handling, food processing, and electronics assembly for over a decade.
Why Choose This Product
Every roller is built around the common problems conveyor operators face. The silicone coating is naturally non-marking, so it will not streak, stain, or leave sticky residue on painted panels, glass, or packed goods — an advantage over ordinary rubber and general-purpose PU rollers. Because we control the coating formula in-house, we can adjust surface hardness from Shore A 40 to Shore A 70, helping you tune grip and surface protection for fragile items or high-speed lines. The benefit for your operation is clear: fewer rejected products, lower noise levels, and longer service life between replacements. This is supported by our ISO9001-based quality system, 100% dimensional inspection before shipment, and more than a decade of export experience serving equipment builders worldwide.
- Concentric steel core: Precision-machined to keep roundness stable, reducing belt wear and improving tracking over the roller life.
- Primer-bonded coating: A special primer layer locks the silicone to the steel core, preventing peeling or slipping during long production runs.
- Smooth crown option: A slight crown profile keeps conveyor belts naturally centered without extra guide hardware.
- Anti-static silicone: Available for electronics assembly and paper handling lines where static discharge can cause issues.
- Clear traceability: Each roller can be engraved with a batch number for quality tracing and repeat ordering.

Material Properties Reference
| Property | Performance |
|---|---|
| Non-Marking Performance | Leaves no black streaks or residue on glass, painted panels, or light-colored packaging |
| Abrasion Resistance | Good wear resistance under continuous conveyor operation; suitable for daily multi-shift use |
| Temperature Resistance | Operates from -60 °C to +200 °C, covering heat tunnels and cold storage lines |
| Chemical Resistance | Resists many industrial oils, mild acids, and common cleaning agents |
| Noise Level | Low-noise rolling at conveyor speeds from 0.1 m/s to 1.5 m/s |
| Rebound Elasticity | High rebound reduces energy loss and supports smooth, stable movement |
| Hardness Range | Shore A 40 to 70, providing a soft to medium contact surface for different goods |
For glass panels, painted components, or polished sheet metal, a softer coating around Shore A 40–50 is usually preferred because it protects the product surface. For heavier boxes or higher line speeds, Shore A 60–70 improves wear resistance while maintaining the non-marking benefit. Send us your load, speed, and product details, and our engineers will recommend a suitable silicone formulation backed by expert advice and a competitive price suggestion for your market.
About Us
We are a China-based manufacturer specializing in silicone coated rollers and precision conveyor components. Our production team has hands-on experience in multi-layer coating, CNC machining, and surface quality control, with a practical understanding of what works on real production lines. We serve industries such as packaging, material handling, food processing, and electronics assembly. With OEM/ODM capabilities and direct factory pricing, we help international buyers reduce sourcing cost and lead time without sacrificing quality. Our quality management system follows ISO9001 principles, and we can provide RoHS-compliant and food-grade silicone options on request.
Factory & Equipment
Our workshop is equipped with CNC lathes, centerless grinding machines, automatic coating lines, and a temperature-controlled curing room. Production follows a written process card at every stage, and rollers are checked after machining, after coating, and again before packing. Overseas clients are welcome to arrange a factory visit or a video tour, and we can share production photos or progress videos on request.
Production & Inventory Policy
Lead time: Actual delivery time depends on raw material availability, production scheduling, and seasonal peak demand, so it may vary within a reasonable range. We will confirm a practical delivery estimate after order confirmation and keep you informed if the schedule changes.
Stock status: We generally do not keep finished goods in stock, but some popular standard models are available from time to time. Real-time inventory changes with sales and production, so we recommend checking current availability with our sales team before you place an order.
Bulk and urgent orders: If you have large-volume or urgent requirements, please discuss capacity and scheduling with us early. We will work around your timeline as closely as possible.
Frequently Asked Questions
Can you customize the diameter, length, and shaft type for silicone coated wheels?
Yes. As a professional custom solution provider, we adjust roller diameter, length, coating thickness, hardness, and shaft configuration to suit your conveyor design. Send us your drawings or load and speed parameters, and we will recommend a suitable structure with a drawing for confirmation. OEM/ODM projects are welcome, and our engineering team can advise on material selection and tolerances based on your application.
Why choose non-marking silicone instead of rubber or PU?
Standard rubber and many PU compounds can leave dark streaks or residue on product surfaces, which becomes a serious issue for painted panels, glass, or light-colored packaging. Our custom non-marking silicone coated smooth conveyor roller is formulated to avoid those marks, run quietly, and withstand temperatures from -60 °C to +200 °C. This makes it a more reliable choice for clean conveying lines and temperature-sensitive environments.
What is your MOQ and how does wholesale pricing work?
For standard sizes, the MOQ is usually 10 pieces. Custom diameters and shafts may need a slightly higher MOQ depending on tooling and setup. Wholesale pricing depends on quantity, coating thickness, and surface finish. Contact us with your target quantity, and we will provide a competitive price suggestion for the current market.
How do you control quality during production?
We follow ISO9001-based procedures in our factory. Each roller is inspected for outer diameter tolerance, coating adhesion, and surface appearance before packing. A material test certificate and dimensional report can be provided with the shipment. Third-party inspection is also supported if your buying process requires it.
Can silicone coated rollers be used in high-temperature or food processing lines?
Yes. The silicone layer can operate continuously up to 200 °C, which suits drying lines and heat tunnels. For food processing conveyors, we can formulate a food-grade silicone compound. Please specify your requirements when ordering so we can select the right additive and curing process.
What is the typical delivery time for custom orders?
Typical lead time is 15 to 25 working days for custom rollers, depending on quantity and coating schedule. Large orders or special core materials may take a little longer. We will confirm the lead time in the quotation and communicate promptly if any raw material or production factor changes.
Do you support samples before bulk purchase?
Yes. We recommend approving a sample before bulk production, especially for custom sizes or special hardness. The sample cost is usually deducted from the first production order once you place the bulk order.
