Description
Custom Non-Marking Silicone Coated Wheels Smooth Conveyor Roller
Our custom non-marking silicone coated wheels and smooth conveyor rollers are engineered for production lines where surface protection, quiet operation, and stable traction are essential. As a professional manufacturer and supplier in China, we combine a specialized high-temperature vulcanized silicone coating with precision-machined steel or aluminum cores to reduce product marking, vibration, and maintenance downtime. Compared with standard rubber or polyurethane, our silicone compound offers a low-friction, non-stick surface that protects painted, polished, or printed goods while maintaining consistent rolling performance. Every unit is checked for dynamic balance, coating adhesion, and wear performance under our ISO9001 quality system, and we back each order with more than 10 years of factory expertise. Whether you need OEM/ODM customization for a new conveyor system, standard-size rollers, or wholesale supply for large-scale distribution, we provide expert advice and a transparent price suggestion to help you choose the most cost-effective solution for your market. Every model in our range is available for sale with full OEM/ODM support.
Why Choose This Product?
Every production environment has different load, speed, and cleanliness requirements. Our silicone coated roller provides a practical answer because it combines a non-stick, anti-marking surface with strong dimensional stability and reliable rolling behavior, which means fewer rejects, less downtime, and lower operating costs for your facility.
- Anti-marking silicone surface: the smooth low-surface-energy layer leaves no scuffs or residue on painted, polished, or printed products, reducing rework and protecting surface finish.
- Steel or aluminum core options: provide higher rigidity and better load support than standard rubber rollers, ensuring stable running over long production periods.
- Smooth and quiet operation: the low-friction silicone layer minimizes noise and vibration, protecting both the conveyed product and the conveyor frame itself.
- Customizable hardness, color, and shaft design: delivers a custom solution for different line speeds, temperature conditions, and product sensitivity requirements.
- Built on proven factory experience: our team has more than 10 years of roller manufacturing experience and follows ISO9001 quality procedures at every production stage.

Material Properties Reference
| 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 |
| EPDM | 20-95 A | Good ★★★ | Poor | Good |
| Silicone | 40-90 A | Fair ★★ | Good | Moderate |
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.
Material Properties of Silicone Coating
The silicone coating is selected for applications where standard rubber or polyurethane may leave marks or create too much friction. These properties help you compare performance and choose the right roller for your production environment.
| Property | Typical Value | Benefit |
|---|---|---|
| Hardness range | 20 – 80 Shore A | Flexible hardness selection for soft or firm contact |
| Tensile strength | 5 – 10 MPa | Supports reliable coating integrity during operation |
| Elongation at break | 300 – 600% | Helps the coating absorb impact without cracking |
| Tear strength | 10 – 25 kN/m | Improves resistance to edge damage and cuts |
| Friction coefficient | 0.3 – 0.5 on steel | Balances grip and smooth product flow |
| Temperature resistance | -60°C to +250°C | Works in hot or cold production environments |
| Non-marking behavior | Excellent on painted or polished parts | Protects surface finish and reduces product waste |
| Chemical resistance | Water, alcohol, dilute acids | Suitable for cleaning agents and washdown areas |

Frequently Asked Questions
Can you customize the roller diameter, silicone hardness, and shaft design?
Yes, we offer full customization for diameter, length, coating hardness, shaft style, and bearing type. Many customers choose our custom non-marking silicone coated wheels and smooth conveyor roller to match the exact speed, load, and product protection needs of their production line.
What is the MOQ for custom silicone coated rollers?
The MOQ depends on the roller size and core material. For standard sizes, we can often accept a small trial order. For custom diameters or special coatings, a moderate MOQ helps us manage production efficiency. Please contact us for a specific price suggestion.
How does the silicone coating prevent marking on conveyor surfaces?
The smooth silicone surface has low surface energy and a slightly softer contact area compared to hard rubber or metal. This reduces friction and pressure marks, especially on painted, polished, or printed products, which directly improves product yield and reduces rework costs.
Can these rollers be used in high-temperature or food-contact environments?
Yes. Silicone can typically operate between -60°C and +250°C, and we offer food-grade silicone material for packaging or food processing lines. Please confirm your operating temperature and any specific compliance requirement so we can recommend the right formula.
What is the typical lead time for bulk orders?
For standard rollers, lead time is usually around 2 to 4 weeks. Custom sizes, coatings, and bearing options may take longer depending on material availability and current factory scheduling. We recommend reaching out early so we can plan production according to your deadline.
Do you provide samples for testing before mass production?
Yes. We can supply samples after confirming the technical specification. Sample cost and delivery time depend on the design, but the testing period helps ensure the roller performs well in your actual application.
How do I choose between silicone, rubber, and polyurethane coating?
Silicone is often the best choice for non-marking, high-temperature, or low-noise applications. Rubber offers good grip and wear resistance at a lower cost. Polyurethane provides excellent load capacity and abrasion resistance. Our team can offer expert advice based on your product type, line speed, and surface sensitivity.
