Description
Custom Non-Marking Silicone Coated Wheels for Smooth Conveyor Rollers
Why Choose This Product
Our silicone coating uses an exclusive non-marking compound, and the contact surface is finished to ensure smooth, quiet rotation. Unlike standard rubber or polyurethane rollers, this silicone stays flexible at low temperatures and remains stable at high temperatures, which reduces the risk of hardening, cracking, or leaving black marks on expensive flooring. This translates into fewer belt failures, quieter operation, and less downtime for your material handling equipment.
Every roller is tested under continuous load cycling before shipment, and the factory is ISO9001 certified, with quality inspection reports available for each batch. Since 2012, we have supplied these silicone coated wheels to conveyor manufacturers in Europe, North America, and Southeast Asia, supporting both standard replacements and fully customized designs. Roller diameter, width, shaft type, silicone hardness, and color can all be tailored to your equipment requirements.
Typical applications: Conveyor systems (belt, roller, gravity), warehousing and distribution centers, food processing lines, electronics assembly, automated material handling equipment, packaging machinery, cleanroom conveyor systems, and battery manufacturing lines.

Details Images
The standard construction includes a precision-machined steel or aluminum core with a seamless silicone coating layer. Coating thickness is typically 3–8 mm depending on the load rating and application type. The smooth outer surface has consistent roundness and dynamic balance, which keeps rotation stable even at higher conveyor speeds. Custom laser marking is available on the roller surface for your brand or product code, and a dust-proof end cap can be added to protect the bearing area from contamination.
Material Properties
| Property | Test Result | Customer Benefit |
|---|---|---|
| Surface hardness | 40–80 Shore A | Balanced load support with enough surface compliance for smooth conveying |
| Non-marking | No residue on polished surfaces | Keeps floors and transported products clean |
| Heat resistance | Stable up to 200°C | Works reliably in high-temperature production lines |
| Compression set | Less than 2% after 72 h at 100°C | Maintains roller shape for consistent performance over time |
| Friction coefficient | 0.4–0.6 (smooth surface) | Smooth movement without slipping or jerking |
These confirmed properties show that the non-marking silicone compound delivers a balanced combination of cleanliness, durability, and thermal stability. Custom hardness from Shore A 40° to 80° is available from our factory for different load and speed requirements.

Production & Inventory Policy
Lead time: We provide a delivery estimate after order confirmation, and actual lead time may vary reasonably due to raw material supply, production scheduling, and logistics. We will keep you informed and coordinate closely throughout the process.
Stock status: We generally produce to order. Some popular standard sizes are kept in stock, but actual stock quantities change dynamically with sales and production. Please contact us for real-time availability before placing an order.
Bulk & urgent orders: For large-volume or urgent orders, we recommend discussing capacity and scheduling with our team in advance. We will do our best to align with your timeline.
Frequently Asked Questions
1. Can you customize the diameter, width, shaft type, and silicone hardness of the wheels?
Yes. As a professional custom solution provider, we can adjust the roller diameter, width, core material, shaft type, and silicone hardness according to your drawing or application. Our engineering team confirms every design detail before production to ensure the final roller matches your equipment requirements.
2. What is the MOQ for custom silicone coated conveyor rollers?
The standard MOQ is 10 pieces for regular sizes. For fully customized dimensions or special silicone compounds, the MOQ is usually 50 pieces. You are welcome to order samples for testing first, and the sample cost is refundable when you move forward with a bulk order.
3. What silicone hardness do you recommend for heavy-load conveyors?
For heavy-load applications, we generally recommend 60–70 Shore A silicone because it combines stable load support with enough surface compliance to protect the conveyed goods. If you share the roller size, load weight, and line speed, our technical team can provide a more specific recommendation based on similar project experience.
4. Do you provide samples before placing a bulk order?
Yes, samples are available. Sample production takes about 7–10 days, and the sample cost can be deducted from your first formal order. Freight is usually covered by the buyer, but we can discuss the terms for long-term cooperation.
5. Can you supply anti-static silicone coated wheels for electronics production lines?
Yes, we offer an anti-static silicone formula with surface resistance controlled between 106 and 109 Ω, which is suitable for ESD-sensitive environments such as electronics assembly, cleanroom conveyor systems, and battery manufacturing lines.
6. How long is the lead time for custom orders?
For custom sizes, lead time is generally 15–25 days after design confirmation, depending on material availability and the current production schedule. We will provide an accurate delivery estimate for your specific order and keep you updated if any adjustment is needed.
7. What payment methods do you accept?
We accept T/T, L/C, and Western Union for international orders. Payment terms can be discussed based on the order value, product type, and our cooperation history. For repeat customers, more flexible arrangements may be available.
