Huco Flexible Coupler, 17 mm OD, 27 mm Length, Aluminium Hub, Nickel Bellows, Screw Style 321.17.3131

Huco 321.17.3131 Flexible Coupler is a high-performance shaft coupling solution designed for use in mechanical power transmission applications. Featuring a 17 mm outside diameter and a 27 mm length, this coupler is engineered to connect two rotating shafts while compensating for angular, parallel, and axial misalignment. Its robust construction includes an aluminium hub for lightweight strength and electrodeposited nickel bellows that provide excellent flexibility, corrosion resistance, and long-term durability. The screw-style fixing and M3 screw size ensure secure and simple installation, making it ideal for demanding industrial and laboratory environments.

With a maximum operating speed of 5000 rpm and torque rating of 132 Ncm, the Huco 321.17.3131 Flexible Coupler delivers reliable performance and high torsional stiffness. Its moment of inertia is rated at 36.2 x 10-8 kg/m², allowing for accurate translation of rotational motion, which is essential for sensitive instrument-driven applications. The coupling supports angular misalignment up to 18°, parallel misalignment of up to 3 mm, and axial misalignment up to 1.78 mm, making it suitable for complex assembly layouts and equipment where alignment precision cannot be guaranteed.

This model is designed to operate in extreme temperature ranges, withstanding minimum temperatures of -50°C and maximum temperatures up to 120°C. The bellows material, electrodeposited nickel, offers high fatigue resistance and maintains performance even under repetitive or incremental loading conditions. Users can confidently deploy this coupler for equipment requiring smooth and accurate transmission, such as laboratory automation, industrial machinery, analytical devices, and control systems.

The Huco 321.17.3131 model adheres to ISO 77 and BS 46 Pt. 1, 774 standards, ensuring consistent quality and compatibility with international requirements. Its ergonomic screw-style fixing simplifies the assembly and maintenance process, while its compact size enables easy integration in tight spaces.
