Description
Custom High Temperature Silicone Coated Rollers Resistant – Smooth Non-Marking Conveyor Solutions
Why choose this industrial silicone roller?
The combination of high-temperature silicone coating and precision-machined cores delivers reliable performance in demanding conveyor applications. Our rollers maintain stable surface hardness and show minimal wear after extended operation, which reduces downtime and lowers replacement costs. The non-marking silicone layer also keeps sensitive products clean, an important benefit for food packaging and electronics assembly lines.
With strict process control at every step, samples are available for performance verification, and our engineering team can advise on the best coating thickness and core structure for your load conditions. Custom roller compounds (silicone, with optional FDA-grade), hardness from Shore A 20° to 80°, and surface finishes (smooth ground Ra 0.05–0.8µm, textured) are available. ISO9001 certified, our rollers offer superior heat resistance and low compression set, which means longer intervals between re-grinding and fewer replacements.
Typical applications: Conveyor systems, printing presses (flexo, gravure), label laminating, plastic film processing, packaging machinery, textile finishing, paper mills, coating equipment, and food handling (with FDA-grade compound). This product is offered as a top professional custom solution for global buyers looking for consistent quality and long-term supply.

Commonly Used Elastomer Properties (Material Performance)
| Compound | Hardness Range (Shore A) | Abrasion Resistance | Tear Resistance | Load Bearing |
|---|---|---|---|---|
| Silicone | 40-90 | 1 | 1 | 1 |
| Nitrile/PVC | 20-95 | 4 | 3 | 3 |
| EPDM | 20-95 | 4 | 3 | 3 |

| Neoprene | 5-95 | 3 | 4 | 4 |
| Hypalon | 30-95 | 4 | 4 | 4 |
| Hydrogenated Nitrile | 50-98 | 5 | 5 | 5 |
| Natural Rubber | 25-98 | 5 | 5 | 5 |
| Polyurethane | 20-98 | 5 | 5 | 5 |
| Carboxylated Nitrile | 45-95 | 5 | 5 | 5 |
Ratings: 1 = low, 5 = high. Silicone offers excellent heat resistance and non-stick properties but lower mechanical strength; for heavy-duty conveying, polyurethane or natural rubber may be preferred. Our factory can produce custom hardness from Shore 20A to 98A across various compounds, and we help you choose the best material for your specific application. In our lab tests, the high-temperature silicone coating demonstrates a tensile strength of 8.5 MPa, tear strength of 38 kN/m, and abrasion loss ≤0.05 cm³ per 6.45 cm². It also passes a non-marking test with no surface residue after 500 hours of contact, and withstands 260°C × 72h without cracking.

Factory & Equipment
Our Certifications (ISO9001, RoHS, Testing Reports)
Our production facility is equipped with automatic coating lines, multi-axis CNC machining, and dynamic balancing machines. Each roller goes through a three-stage quality check: dimensional measurement, coating adhesion test, and running surface inspection. This setup allows us to maintain high uniformity for large wholesale orders while keeping the flexibility needed for custom samples and small trial runs. Our facility is ISO9001:2015 certified, and the silicone materials we use are compliant with RoHS and REACH requirements. Test reports are available on request, including hardness, tensile strength, heat aging and non-marking verification.
Production & Inventory Policy
Lead time: Actual lead time may vary depending on raw material supply, production schedules and peak-season workload. We will provide a realistic delivery estimate after order confirmation and keep you informed throughout the process.
Stock status: In principle we do not hold large stocks, but some fast-moving standard sizes may be available. Please contact our sales team to confirm real-time availability before ordering.
Bulk & urgent orders: For large orders or urgent requirements, we kindly suggest discussing capacity planning with our team in advance. We will do our best to align with your schedule.
Frequently Asked Questions
1. What temperature can these silicone coated rollers withstand continuously?
These custom high temperature silicone coated rollers resistant to continuous operation are verified up to 260°C through 72-hour heat aging tests at 260°C. This makes the rollers suitable for drying ovens, heat tunnels and other high-temperature conveyor sections. In addition, the coating maintains hardness stability within Shore A 23°±3°, so you get consistent performance over the full working range.
2. Why are these rollers non-marking?
The silicone formula is specifically blended without color-transfer additives and cured under clean production conditions. In a 500-hour contact test, no surface residue was transferred to the test panels. For food packaging or electronic component conveying, this avoids product contamination and reduces the need for frequent cleaning.
3. Can I get custom sizes and hardness?
Yes. As an OEM/ODM supplier, we offer custom roller diameter, length, shaft design, coating hardness, color and even anti-static properties. Send us your drawing or intended application; our engineers will provide expert advice on the most suitable coating thickness and core material.
4. What is the MOQ for wholesale orders?
Our MOQ is flexible. For standard sizes, we can accept small trial orders. For bulk wholesale programs, we offer competitive pricing and scheduled production. Just contact us with the quantity and target market, we will give you the best price suggestion.
5. How long is the delivery time?
Sample orders usually take 3-5 days to produce, while regular production runs take approximately 7-15 days depending on quantity and coating complexity. During peak season, lead time may extend, and we will confirm the actual date after order confirmation.
6. Do you provide certificates or third-party inspection support?
We are ISO9001:2015 certified, and materials are RoHS and REACH compliant. We welcome third-party inspections and can share test reports for hardness, tensile strength, abrasion resistance and heat aging upon request.
7. What payment and shipping methods are available?
We support T/T, L/C at sight, and for samples Western Union or PayPal can be arranged. For shipment, we work with major sea, air and express carriers to give you the most cost-effective option for your destination.
