Hebei Speed Torque Transmission Technology Co., Ltd., established in 2017 with a factory area of 3,000-5,000 square meters, is a trusted manufacturer in the power transmission industry. With an annual export value of US$5-10 million and a skilled team of 101-200 employees, we specialize in producing high-quality couplings and transmission components. Our Kc Coupling Roller Chain Coupling Set with Chain and Sprocket is designed for general machinery applications, offering reliable torque transmission, easy installation, and excellent value for money. Backed by ISO9001 certification, this product is exported to major markets worldwide, including North America, South America, Europe, Asia, and Africa, ensuring global standards of quality and performance.
The roller chain coupling set consists of two hardened sprockets (hubs) and a double-strand roller chain that connects them. It provides a flexible yet efficient connection between shafts, accommodating minor misalignments (angular, parallel, and axial) while absorbing shock loads. Ideal for applications such as conveyors, pumps, mixers, fans, and general industrial machinery, this coupling offers a compact design with high torque capacity relative to its size. Below are the key features and technical specifications:
| Parameter | Description |
|---|---|
| Model Range | KC-10 to KC-40 (customizable upon request) |
| Chain Type | ANSI 40, 50, 60, 80 double-strand roller chain |
| Material | 45# steel (carbon steel) or 40Cr alloy steel, hardened |
| Bore Diameter | 10 mm – 80 mm (standard), up to 100 mm upon request |
| Max Torque | 15 Nm – 3500 Nm |
| Max Speed | 800 – 6000 rpm (dependent on size and balance) |
| Misalignment Capacity | Angular ≤ 1°, Parallel ≤ 0.5 mm, Axial ≤ 2 mm |
| Surface Treatment | Black oxide (standard), zinc plating, or customized |
Key Features and Benefits:
High Torque Transmission: The double-strand roller chain distributes load evenly, providing excellent torque capacity even in demanding applications.
Shock Absorption: The chain and sprocket design naturally dampens vibration and shock loads, protecting connected equipment from damage.
Easy Installation & Maintenance: Simple bolt-on design allows quick mounting without special tools; chain can be easily replaced when worn.
Cost-Effective: Compared to other flexible couplings, the roller chain coupling offers a competitive price without sacrificing reliability.
Customizable Options: Bore size, keyway, set screw location, and tooth count can be tailored to your specific shaft dimensions and application requirements.
Long Service Life: Precision-machined sprockets and heat-treated chain ensure durability under continuous operation.
Wide Application Range: Suitable for general machinery, agricultural equipment, packaging lines, and industrial drives.
Our Kc Coupling Roller Chain Coupling Set is manufactured under strict quality control per ISO9001 standards. Each set undergoes dimensional inspection and torque testing before shipment. We offer flexible packaging options and can supply the coupling as a complete set (two sprockets + chain) or individual components. For special requirements such as stainless steel material, high-temperature resistance, or non-standard chain pitch, please contact our sales team for a custom solution.
Frequently Asked Questions (FAQ)
Q: What is the main advantage of a roller chain coupling over other types?
A: Roller chain couplings provide excellent torque transmission with some flexibility, are easy to install and replace, and are generally more cost-effective than elastomeric or metal disc couplings for moderate misalignment applications.Q: Does this coupling require lubrication?
A: Yes, periodic lubrication of the roller chain is recommended to extend service life. We supply the chain with initial lubrication; maintenance intervals depend on operating conditions.Q: Can this coupling handle continuous high-speed operation?
A: Yes, but the maximum RPM depends on the size and balance. For speeds above 6000 rpm or critical applications, we recommend a balanced set. Please consult our technical team.Q: How do I select the correct coupling size for my application?
A: You need to know shaft diameters, torque requirements, RPM, and available space. Use our selection guide or provide these parameters to our engineers for a precise recommendation.Q: Is the chain replaceable separately?
A: Yes, the chain can be replaced individually when worn, while the sprockets typically last longer. We offer spare parts for all models.Q: What tolerances are maintained for bore and keyway dimensions?
A: Standard bore tolerance is H7 (ISO system), and keyways are cut per BS or DIN standards. Custom tolerances available on request.Q: Do you provide technical drawings or 3D models?
A: Yes, we can share dimensional drawings in PDF or 3D file formats (STEP, IGES) for most standard models upon request.Q: What is the typical lead time?
A: For standard sizes, lead time is 15-25 days. Custom orders may require 30-45 days, depending on complexity and quantity.
