Description
Custom Intermittent Duty Silicone Rollers for Start–Stop Conveyor Systems
Why Choose This Product
Intermittent duty places unique stress on conveyor rollers: constant acceleration, deceleration, and standing dwell times can cause flat spots, surface marking, and premature wear. Our silicone-coated rollers solve these problems through a balanced combination of material engineering and manufacturing precision.
- Non-marking silicone coating leaves no residue on goods, critical for cleanroom or painted-surface handling.
- Optimized Shore A hardness provides a firm yet slightly compliant surface, reducing impact noise during start-stop cycles.
- Steel or aluminum cores are precision-machined to ensure low rolling resistance and consistent concentricity under dynamic load.
- Custom diameters, lengths, shaft options, and colors are available to retrofit existing conveyor systems without major modification.
Backed by ISO9001 quality systems and over a decade of export experience, our factory ensures every roller is tested for balance, coating adhesion, and dimensional accuracy before shipment.

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. For our custom intermittent duty silicone rollers, in-house laboratory tests show abrasive weight loss ≤0.08 g after 1000 Taber cycles, no visible residue after 200 start-stop cycles, compression set ≤20% (22h at 70°C, 25% deflection), stable adhesion at the bond line, and no cracking after 72h heat aging at 100°C. 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.

Production & Inventory Policy
Lead time: Actual delivery time may vary due to raw material availability, machine scheduling, and peak season fluctuations. After order confirmation, we provide the most accurate estimate and keep transparent communication.
Stock status: We generally do not hold large finished-goods inventory, but some popular standard models may have limited dynamic stock (which changes as sales and production progress). Please confirm real-time availability with our team before ordering.
Bulk & urgent orders: For mass production or tight schedules, we recommend early discussion of capacity and production planning. We will do our best to support your timeline.
Frequently Asked Questions
1. What makes these silicone rollers suitable for intermittent duty and start-stop applications?
Intermittent duty requires a roller surface that recovers quickly after static compression and does not develop flat spots. Our silicone compound is formulated with low compression set and high resilience, which means the roller retains its circular profile even after long dwell times between movements. This reduces vibration and keeps your conveyor running smoothly through frequent start-stop cycles.
2. Can I get custom intermittent duty silicone rollers in non-standard sizes?
Yes. As a custom solution focused manufacturer, we offer rollers in a wide range of diameters, lengths, shaft designs, and hardness values. We also support OEM/ODM projects where the roller is designed around your existing equipment. Just provide your drawings or key dimensions, and our team will offer expert advice on the most suitable material and construction.
3. Are these silicone coated wheels truly non-marking on delicate surfaces?
Our silicone coating is sulfur-free and specially compounded to avoid leaving marks on painted panels, glass, or plastic housings. We test the non-marking property using a white cloth rub test after repeated contact, and the result shows no residue transfer. For applications involving very sensitive surfaces, we can also adjust the surface texture or hardness to further reduce friction marking.
4. What is the minimum order quantity and lead time?
For standard sizes, the sample order is available with a lead time of about 5–7 working days after specification confirmation. For bulk production, the MOQ is generally 10 pieces for custom sizes, and lead time depends on quantity, material availability, and current factory load. We provide a confirmed schedule after you place the order and update you proactively if anything changes.
5. How do you ensure quality consistency across large orders?
We follow a strict incoming material inspection, in-process quality check, and final pre-shipment test protocol. Each batch is tested for hardness, dimension, coating thickness, and visual appearance. Our ISO9001 documentation system keeps batch records for traceability. We also welcome third-party inspections if your company has specific quality requirements.
6. What is the typical price range for custom silicone conveyor rollers?
Price depends on core material, size, coating thickness, and order quantity. As a factory-direct manufacturer in China, we offer competitive wholesale pricing without compromising on material quality. Please share your specification and target quantity, and we will provide a detailed quotation with price suggestions that fit your market positioning.
7. What are the payment and shipping methods?
We accept T/T, L/C, PayPal for sample orders, and other payment methods can be discussed for long-term cooperation. For shipping, we work with major international express carriers for samples and express shipments, while bulk orders can be delivered by sea, air, or rail according to your destination and lead time preference.
