Product Features & Advantages

Advantage	Benefit
High-Strength Aluminium Alloy	Lightweight, corrosion-resistant, and durable – reduces overall system inertia.
Compact Design	Small size and light weight – ideal for space-constrained installations.
Simple Structure	Easy to install and replace – reduces downtime.
Pin & Bush Design	Smooth power transmission with minimal axial thrust.
Wide Torque Range	4-15680 N·m – suitable for a broad spectrum of applications.
Cost-Effective	Excellent performance-to-cost ratio for medium-power transmission systems.
OEM Customization	Custom bores and materials available to meet specific requirements.
Long Service Life	Reliable operation when shaft misalignment is kept within specified limits.

Product Structure

Two Aluminium Hubs – Precision-machined, lightweight, and corrosion-resistant.
Steel Pins – High-strength pins for torque transmission.
Elastomer Sleeves/Bushes – Provide damping and compensate for minor misalignment.

💡 How it works: The FCL coupling utilizes a pin-and-bush design. Steel pins on one hub engage with elastomer-lined holes on the other. This setup transmits torque smoothly, dampens vibrations, and accommodates minor angular and radial misalignment. The simple structure allows for easy disassembly by removing the coupling bolts.

Applications

Gearboxes & Speed Reducers – Reliable power transmission.
Hoists & Cranes – Durable and maintenance-friendly.
Compressors – Smooth, vibration-damped operation.
Conveyors – Ideal for material handling systems.

FAQ

Q: What is an FCL coupling?
A: An FCL coupling is a pin-and-bush type flexible coupling, widely used for its compact design, easy installation, and convenient maintenance. It is commonly used in medium and minor power transmission systems.

Q: What is the advantage of the aluminium construction?
A: Aluminium provides a lightweight, corrosion-resistant solution that reduces overall system inertia and is ideal for applications where weight is a concern.

Q: What is the torque and speed range?
A: The FCL series covers a torque range from 4 N·m to 15,680 N·m and speeds up to 4,000 RPM (depending on the model).

Q: Is the coupling rigid or flexible?
A: While it is described as rigid, the pin-and-bush design with elastomer sleeves provides some flexibility, allowing it to compensate for minor angular and radial misalignment.

Q: What are the common applications?
A: FCL couplings are widely used in gearboxes, speed reducers, hoists, compressors, conveyors, spinning and weaving machines, and ball mills.

Q: Can I get a custom bore size?
A: Yes. We offer OEM customization – custom bores, keyways, and materials are available.

Q: What is the allowable misalignment?
A: The permissible relative displacement is radial 0.2-0.6mm and angular 0°30′ to 1°30′.
