Description
Custom Non-Marking Silicone Coated Wheels – High-Quality Smooth Conveyor Roller Solutions
Our custom non-marking silicone coated wheels are engineered for smooth conveyor roller systems that demand quiet operation, clean handling, and long service life. As a top China manufacturer with over 15 years of experience, we combine a precision steel or stainless steel core with a premium non-marking silicone rubber tread that delivers outstanding performance in demanding production environments. The silicone compound provides a high-friction yet non-staining surface, so glass, painted metals, and sensitive packaging move without scuffs or residue, reducing rejection rates and maintenance costs on your line. Compared to standard rubber or polyurethane, our silicone coating maintains elasticity and damping over a wider temperature range (-30°C to +200°C), ensuring reliable operation in drying, curing, and cold-storage conveyor applications. We back every wheel with ISO9001 certification and rigorous dynamic balancing, and we offer expert advice and transparent price suggestions to help you select the optimal specification. Whether you need a standard size or a fully custom OEM/ODM design, our wheels are for sale at competitive wholesale prices, supported by fast sampling and volume production.
Why choose our non-marking silicone coated wheels?
Our customers in the packaging, AGV, and material handling sectors choose our silicone wheels because they solve key pain points: residue, noise, and temperature sensitivity. The non-marking silicone compound leaves no visible marks or residue on glass, painted metal, or plastic surfaces, which helps reduce rejection rates and cleaning time. Its smooth running surface reduces vibration and noise, improving operator comfort and equipment stability, a benefit verified by our operational tests. The steel core provides high structural strength, while the silicone coating delivers excellent wear resistance and consistent coating adhesion. Unlike regular rubber rollers that tend to harden over time and leave black marks, our industrial silicone coating maintains elasticity over a wider temperature range, provides higher resistance to aging, and leaves no residue. We offer full OEM/ODM customization, from Shore hardness and wheel diameter to different core materials, and our engineering team provides free consultation to ensure you get the right compound for your specific application.
- Non-marking silicone compound leaves no black marks or residue on glass, metal, or plastic.
- Smooth running surface reduces vibration and noise, improving operator comfort and equipment stability.
- Customizable hardness, thickness, and dimensions match your specific conveyor load and speed.
- Each wheel is dynamically tested to ensure balanced rotation and consistent coating adhesion, reducing unexpected downtime.

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, clean-room, or product-sensitive conveyor environments. In our operational tests, the non-marking silicone coating delivered a noise level below 30 dB(A) at 1 m and maintained static load capacity up to 300 kg per roller, confirming stable and clean operation for sensitive conveyor lines. Polyurethane remains the top choice for high-abrasion and heavy-load applications. We can recommend the optimal material based on your working conditions.

Frequently Asked Questions
Are these wheels truly non-marking on smooth conveyor lines?
Yes, our custom non-marking silicone coated wheels are designed specifically for smooth conveyor roller systems. The silicone compound is tested to leave no visible marks or residue on glass, painted metal, or plastic surfaces, which helps reduce rejection rates and cleaning time.
Can you customize the silicone hardness and wheel size for my existing equipment?
Absolutely. We offer full OEM/ODM customization, including Shore hardness from 40 to 70 A, wheel diameter from 80 mm to 150 mm or larger, and different steel core materials. Send us your drawings or a sample, and our engineering team will provide a custom solution with expert advice on load capacity and coating thickness.
What is the MOQ for a wholesale order?
For standard sizes, the MOQ is usually 100 pieces. For trial orders or custom prototypes, we can agree on a lower quantity to help you validate the design. We work with both new importers and established distributors, so simply contact us with your target price and volume.
How does the non-marking silicone coating compare to regular rubber?
Regular rubber rollers often leave black marks on delicate products and tend to harden over time. Our industrial silicone coating maintains elasticity over a wider temperature range, provides higher resistance to aging, and leaves no residue. This advantage means less downtime and lower replacement costs for your production line.
What is the typical delivery time?
Delivery usually takes 15 to 25 working days after drawing approval and deposit. The actual lead time may vary based on raw material supply and production schedules, but we will always communicate the estimated date clearly and update you if any adjustment is needed.
Can you provide custom packaging, labels, or pallet configurations?
Yes. We offer custom export packing, private labels, and pallet configurations to match your logistics and branding requirements. Just share your packaging specification, and we will implement it for both trial and bulk shipments.
Do you support pre-shipment inspection and third-party testing?
We do. We can provide test reports for hardness, abrasion resistance, load capacity, and non-staining properties. If you need third-party inspection, we are glad to coordinate with services such as SGS or BV at your factory before loading.
