Description
Custom Non-Marking Silicone Coated Wheels and Smooth Conveyor Rollers
Our custom non-marking silicone coated wheels and smooth conveyor rollers are engineered for material handling systems that demand clean operation, low noise, and long service life. As a top professional manufacturer in China, we supply high-performance rollers with an exclusive silicone coating that prevents surface marking on finished goods, making them ideal for food processing lines, electronics assembly, packaging conveyors, and automated logistics equipment. Each wheel is built around a precision steel or aluminum core with a durable silicone outer layer, offering superior wear resistance and stable dimensional accuracy. These rollers are for sale with full OEM and ODM support, backed by ISO9001 certified production processes and competitive wholesale pricing. Whether you need a standard replacement roller or a fully custom solution, our team provides expert advice on hardness, shaft design, and surface finish to match your specific conveying requirements.
Why Choose This Product
These silicone coated wheels stand out because they combine several critical attributes that are usually traded off against one another: non-marking performance, smooth operation, and long-term durability. The silicone coating features a Shore A 55-70 hardness range, which provides enough compliance for quiet contact yet remains firm enough for consistent tracking. Unlike standard rubber rollers, the silicone surface resists oil, ozone, and aging, so it maintains a clean, streak-free finish on painted, laminated, or polished parts. This advantage translates directly into lower rejection rates and less rework for your production line. Our rollers are also dynamically balanced to minimize vibration, reducing wear on bearings and conveyor frames over time. Evidence from our in-house testing shows that these rollers maintain their coefficient of friction within a narrow tolerance after 5,000 hours of continuous operation, a reliability level that is backed by our 24-month warranty and responsive after-sales support.

Material Properties
Understanding material performance is key to selecting the right roller for your application. The table below compares the key characteristics of our silicone coating against standard industrial rubber compounds.
| Property | Silicone Coating | Standard Rubber |
|---|---|---|
| Non-Marking Performance | Excellent, leaves no residue | Moderate, can leave streaks |
| Abrasion Resistance | High, tested per ASTM D4060 | Medium |
| Oil and Chemical Resistance | Good against oils and mild solvents | Varies widely by compound |
| Temperature Tolerance | -40 to +200 degrees Celsius | -20 to +80 degrees Celsius |
| Noise During Operation | Low, ideal for quiet environments | Moderate |
| Compression Set | Low, better shape recovery | Medium to high |
For applications that involve high-speed conveyance or sensitive surfaces, the silicone coated option delivers measurably better performance in both cleanliness and longevity. We recommend confirming your specific operating conditions with our technical team so that we can suggest the optimal hardness and core configuration for your conveyor line.
About Us
We are a China-based manufacturer and supplier with 15 years of experience in producing precision conveyor rollers and industrial wheels. Our factory operates with CNC turning centers, automated coating lines, and in-house dynamic balancing equipment, allowing us to maintain strict dimensional tolerances and consistent surface quality. As a top OEM and ODM partner, we provide custom solutions for conveyor system integrators, logistics equipment brands, and machinery manufacturers across Europe, North America, and Southeast Asia. Our engineering team offers expert advice on material selection, hardness tuning, and shaft design, ensuring that every roller matches the exact requirements of your application and market demand. We also welcome customers to visit our facility and see our production capabilities firsthand.
Factory and Equipment
Our production facility covers 8,000 square meters and is equipped with CNC machining centers, automatic rubber coating lines, curing ovens, and testing instruments for hardness, abrasion, and dynamic balance. Every batch is inspected before shipment, and we maintain documented quality records for full traceability. We also support third-party inspections before dispatch, giving you full confidence in the finished goods.
We have hosted customers from more than 20 countries at our factory, where they review material selection, sample testing, and quality control procedures before placing bulk orders. On-site visits are encouraged for serious buyers who want to verify our production capabilities and quality standards directly.
Certifications
Our management system is certified to ISO9001:2015, and our silicone materials comply with RoHS and REACH requirements. For food-grade or medical applications, FDA-compliant silicone compounds are available upon request. Certification documents and test reports can be provided to your quality department for review before order confirmation.
Production and Inventory Policy
Lead time: Actual delivery schedules may vary due to raw material supply, machine availability, and seasonal demand fluctuations. We provide a reliable delivery estimate after order confirmation and keep you updated throughout the production process.
Stock status: We generally produce to order rather than holding large finished-goods inventory. However, some popular standard sizes are kept in stock, and real-time availability changes with sales and production. Please contact us to confirm current stock levels before placing your order.
Bulk and urgent orders: For large-volume or time-sensitive orders, we recommend contacting us early to discuss capacity planning and scheduling. We will do our best to align our production plan with your required timeline.
Frequently Asked Questions
Can you provide custom solutions for existing conveyor systems?
Yes. Our custom non-marking silicone coated wheels and smooth conveyor rollers are fully customizable in diameter, length, shaft type, coating hardness, and core material. Send us your drawings or the exact dimensions of your current rollers, and our engineering team will confirm feasibility and provide a tailored recommendation.
What is the MOQ for custom silicone coated rollers?
For standard sizes, the MOQ is 50 pieces. For fully customized rollers with special shaft machining or FDA-grade silicone, the MOQ is typically 100 pieces. We are flexible with trial orders for sample validation and can discuss lower quantities for first-time cooperation.
How does your silicone coating prevent marking on sensitive surfaces?
Our silicone formulation is specifically engineered with a low-friction, non-reactive surface that does not transfer residues onto painted, laminated, or polished parts. Unlike standard rubber compounds that may contain plasticizers or sulfur residues, our silicone layer is cured through a controlled process that keeps the surface clean and stable even under moderate heat.
What is the typical delivery time?
For standard rollers, delivery is usually 15 to 25 working days after deposit confirmation. Custom rollers with non-standard shafts or coatings generally require 25 to 35 working days. During peak production seasons, schedules may extend slightly; we will always inform you of the realistic timeline at the time of order confirmation.
What payment methods do you accept?
We accept T/T wire transfer, L/C at sight, and PayPal for sample orders. Payment terms can be discussed for long-term contracts and repeat orders, and we are open to flexible arrangements that fit your company’s purchasing policy.
Do you offer warranty on your rollers?
We provide a 24-month warranty covering material and manufacturing defects. If a roller fails due to coating peeling, core deformation, or balancing issues under normal operating conditions, we will replace it free of charge after our quality team verifies the issue.
Can I visit your factory before placing an order?
Certainly. We welcome buyers from around the world to visit our facility in China. You can walk through our production line, inspect test equipment, and discuss your project with our engineers directly. Please contact us in advance so we can arrange transportation and prepare relevant samples for your review.
