Description
Custom Tapered Bore Silicone Coated Rollers Variable Speed
Why choose this product?
Designed for variable speed conveyors, fixed-speed equipment, and AGV systems, each roller features a precision tapered bore that creates a self-centering connection to the shaft. This reduces radial runout and shaft slip, improving tracking stability when conveyor speed changes quickly. The non-marking silicone coating has a naturally smooth surface, leaves no residue on goods, and absorbs minor impacts during transfer.
Custom bore tapers, silicone hardness from Shore A 30° to 70°, and smooth surface finishes are available. Dynamic balancing tolerance is held to strict limits, and our ISO9001-based manufacturing process ensures consistent quality from raw tube to final coating. The result is a longer service life and lower total operating cost compared with standard straight-bore rollers.
Typical applications: Package conveying, assembly lines, material handling systems, food and beverage transfer, clean room equipment, and variable speed conveyor lines.
Technical Specifications

| 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 |
| Nitrile Rubber | 20-95 | 3 | 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.

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. Can you provide custom solutions for tapered bore silicone coated rollers used in variable speed conveyors?
Yes, we are an experienced OEM/ODM supplier in China. Our engineers can help you choose the correct bore taper, silicone hardness, and surface finish for your variable speed line. For example, a softer silicone coating can improve grip on lightweight goods, while a harder formulation supports heavier loads. We can provide custom samples after confirming your shaft design and load requirements.
2. What is the minimum order quantity for custom rollers?
Our usual MOQ is 50 pieces for custom tapered bore silicone coated rollers. If this is a new project or a pre-series evaluation, please talk to us. For many customers we accept a smaller trial order to validate the design before moving to volume production. This flexibility helps you reduce risk while testing our roller performance.
3. How does the tapered bore improve performance in variable speed applications?
The tapered bore creates a self-centering fit on the shaft, which reduces radial runout and prevents the slipping issues commonly seen with straight bores under changing speeds. This helps keep conveyor movement smooth, lowers vibration and noise, and protects both the roller and shaft during long operating cycles.
4. What delivery time can you offer for factory orders?
For confirmed custom orders, our regular lead time is 15–25 working days after drawing approval. Actual lead time depends on raw material availability, production load, and logistics scheduling. We always provide an updated estimate and will tell you immediately if any adjustment becomes necessary.
5. Can I get samples before placing a bulk order?
Yes, sample orders are welcome. We can make pre-production samples with your specified silicone coating, tapered bore dimensions, and shaft fit so you can verify performance on your own equipment. Usually we confirm the sample cost and lead time before starting, and we keep the sample data for consistent repeat orders.
6. Do you support OEM/ODM and wholesale pricing?
Yes, we support OEM and ODM production, custom labels, specialized packaging, and global wholesale supply. Our price suggestion is based on the final configuration, surface treatment, bore size, and order quantity. Send us your drawing and target quantity, and our team will respond with a transparent quote for the market.
7. What packaging options do you provide for international shipping?
Standard packaging includes individual plastic bags and sturdy cartons. For bulk orders, we offer wooden cases, pallets, or container loading. Anti-rust treatment is applied for sea freight. Custom packaging is available upon request.
8. What payment methods do you accept?
We accept bank transfer (T/T), and for smaller orders, PayPal or Western Union. Long-term partners may discuss letter of credit. Ask our team for details. All transactions are secure and transparent.
