Hebei Speed Torque Transmission Technology Co., Ltd., established in 2017 and located in Cangzhou, Hebei, China, is a professional manufacturer of high-quality transmission components. Our factory spans 3,000–5,000 square meters and is staffed by 101–200 experienced employees. We hold ISO9001:2015 certification and export to over a dozen markets worldwide, including North America, South America, Europe, Southeast Asia, and Oceania, with an annual export value of US$5–10 million. Our Nl Nylon Inner Tooth Coupling / Coupled Curved Tooth Gear Nylon Sleeve is designed to deliver reliable, low-noise, and maintenance-free performance in various industrial power transmission applications.
This coupling sleeve is engineered from high-grade nylon material, offering excellent wear resistance, self-lubrication, and vibration damping. The unique curved tooth profile ensures smooth torque transmission and compensates for minor misalignments, protecting connected equipment from shock loads. Whether used in pumps, compressors, conveyors, or gearboxes, this product enhances system efficiency and extends service life.
Key Features & Technical Specifications:
- Material: High-strength nylon (PA6 or PA66) – lightweight yet durable, resistant to oils and chemicals.
- Tooth Design: Curved inner teeth for progressive engagement, reducing peak stress and noise.
- Torque Capacity: Ranges from 50 Nm to 1,200 Nm depending on size (customizable upon request).
- Misalignment Compensation: Axial, radial, and angular misalignment tolerance up to 1–2°.
- Operating Temperature: -40°C to +120°C, suitable for harsh environments.
- Weight Reduction: Up to 60% lighter than traditional metal couplings, reducing rotational inertia.
- Installation: Easy push-fit design; no lubrication or special tools required.
- Custom Options: Available in different colors (black, white), hardness (Shore D 70–85), and custom dimensions.
Technical Parameter Table (Example Sizes):
| Model | Inner Diameter (mm) | Outer Diameter (mm) | Length (mm) | Max Torque (Nm) |
|---|---|---|---|---|
| NL-25 | 14–25 | 55 | 40 | 120 |
| NL-40 | 20–40 | 80 | 55 | 350 |
| NL-60 | 30–60 | 110 | 70 | 700 |
| NL-80 | 40–80 | 140 | 85 | 1,200 |
