Description
Custom Keyway Silicone Rollers with Positive Drive
Why Choose This Keyway Silicone Roller?
This keyway silicone roller is built for conveyors that demand reliable and accurate rotation. The silicone coating delivers high-friction yet gentle handling, so fragile or finished parts move without smudges or scratches. Compared to standard rubber rollers, the silicone compound resists heat and remains flexible over a longer period, which means fewer interruptions and lower running costs.
Each roller uses a precision-machined keyway that locks firmly to the shaft for positive drive, avoiding the rotational slip common with round-bore rollers in start-stop applications. Custom roller compounds, hardness from Shore A 20° to 80°, and surface finishes are available. Dynamic balancing and runout measurement are carried out before dispatch, giving you documented consistency for each batch.
Typical applications: Conveyor systems, packaging machinery, AGV equipment, printing presses, laminating lines, textile finishing, and automated material handling systems where non-marking contact and precise torque transfer are required.

Material Properties
| Property | Standard / Test | Typical Value |
|---|---|---|
| Tensile Strength | ASTM D412 | ≥ 8 MPa |
| Elongation | ASTM D412 | ≥ 400% |
| Tear Strength | ASTM D624 | ≥ 20 kN/m |
| Abrasion Resistance | DIN 53516 | ≤ 0.15 cm³ / 40 m |
| Non-marking Performance | Steel plate test | No residue |

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. Do you offer competitive wholesale pricing for custom keyway silicone rollers?
As a direct China factory, we provide fair pricing based on quantity. For volume orders of 50+ rollers, contact us for a tailored quote. Our OEM/ODM service helps you reduce total cost without sacrificing quality.
2. Can you provide custom sizes for silicone coated conveyor rollers with keyway drive?
Yes, we offer complete OEM/ODM customization for diameter, length, shaft design, keyway standard (GB/ANSI/DIN), hardness, and surface finish. Send us your drawing or target specifications and our engineering team will confirm feasibility.
3. Why choose a keyway positive drive instead of a plain round shaft?
A keyway mechanically locks the roller to the shaft, preventing slippage during sudden starts, stops, or variable load cycles. This improves positioning accuracy and reduces wear on drive components, which is essential for automated conveyors and indexing equipment.
4. What is the typical lead time for volume orders?
Production usually takes 10 to 20 working days for batches up to 500 pieces, depending on raw material availability and the current production schedule. If you have an urgent requirement, please notify us early so we can evaluate possible capacity adjustments.
5. Do you offer OEM/ODM services for roller customization?
Yes, as a professional manufacturer in China, we welcome OEM and ODM projects for custom keyway silicone roller solutions. We can produce according to your drawings, apply your branding, and provide material selection advice for keyway tolerance and silicone formulation.
6. How should I maintain the non-marking silicone surface?
Wipe the roller with a dry or slightly damp lint-free cloth at regular intervals. Avoid exposure to sharp tools, excessive ozone, or prolonged direct ultraviolet light. If you notice a change in surface behavior, our team can provide recoating or replacement guidance.
7. Are these silicone rollers suitable for high-temperature environments?
The standard silicone compound operates reliably between -30°C and 200°C. For continuous exposure above 200°C or below -40°C, please consult our engineers so we can recommend a tailored formulation for your application.
