A chain coupling is a mechanical device used to connect two shafts together for the purpose of transmitting power. It consists of two sprockets, one on each shaft, connected by a double-strand roller chain. This design allows for slight misalignments, including angular, parallel, and axial misalignments, while maintaining efficient power transmission. Chain couplings are known for their durability, high torque capacity, and ease of installation, making them ideal for heavy-duty industrial applications such as conveyors, pumps, and manufacturing machinery.
Below is a detailed table of our chain coupling specifications to help you select the right product for your application. All parameters are based on standard models; custom options are available upon request.

Chain couplings are widely used in numerous applications due to their reliability and flexibility. Common uses include:
What is the maximum misalignment a chain coupling can handle?
Chain couplings can typically handle angular misalignments up to 2.5 degrees and parallel misalignments up to 1.2 mm, depending on the model. Exceeding these limits may reduce efficiency and cause premature wear.
How often should I lubricate a chain coupling?
Lubrication frequency depends on the operating environment and usage. For standard applications, lubricate every 3-6 months with a high-quality grease. In harsh conditions, such as high temperature or dusty environments, monthly lubrication may be necessary.
Can chain couplings be used in high-speed applications?
Yes, certain models are designed for high-speed operations, with maximum speeds up to 5000 RPM. Always refer to the product specifications to ensure the coupling is suitable for your required speed.
What materials are chain couplings made from?
They are commonly made from materials like steel, stainless steel, hardened steel, alloy steel, or carbon steel, chosen for strength, corrosion resistance, and durability based on the application.
How do I select the right chain coupling size?
Consider factors such as shaft size, torque requirements, speed, and misalignment conditions. Use the product parameter table above as a guide, and consult with an engineer if needed for custom applications.
Are chain couplings easy to install and maintain?
Yes, they are designed for easy installation without moving connected equipment. Maintenance involves regular inspection for wear, proper lubrication, and chain replacement if necessary, which can often be done without full disassembly.
What are the signs of a failing chain coupling?
Common signs include unusual noises (e.g., grinding or rattling), visible wear on the chain or sprockets, increased vibration, and decreased transmission efficiency. Regular inspection helps detect issues early.
Can I use a chain coupling in corrosive environments?
Yes, models made from stainless steel or with protective coatings are available for corrosive environments. Ensure the selected model is rated for such conditions to avoid premature failure.
What is the typical lifespan of a chain coupling?
With proper maintenance and within specified operational limits, chain couplings can last several years. Lifespan varies based on usage, environment, and load conditions; regular monitoring is recommended.
Do chain couplings require alignment during installation?
While they accommodate misalignment, initial alignment should be as precise as possible to maximize performance and longevity. Use alignment tools to minimize misalignment within the coupling's tolerances.
