Huco Flexible Bellows Coupler, Aluminium Hub, Electrodeposited Nickel, 6.35 mm OD, 14 mm Length, Screw Style, 321.07.1414

The Huco 321.07.1414 is a high-precision flexible bellows coupler engineered for industrial power transmission applications. Designed with an aluminium hub and an electrodeposited nickel bellows, this coupler ensures reliable and accurate shaft connections, accommodating misalignments and reducing mechanical stress during operation. Its compact dimensions, including a 6.35 mm outside diameter and a 14 mm overall length, make it ideal for systems requiring precise space management and robust coupling performance.

Equipped with a screw style attachment using M2 grub screws, the coupler facilitates secure and straightforward installation. Its bellows design enables it to flexibly connect two rotating shafts, effectively compensating for angular, parallel, and axial offset up to 11 degrees angular misalignment, 1 mm parallel misalignment, and 0.65 mm axial misalignment. This flexibility is especially valuable for drives associated with instrumentation and industrial machines, where precise transmission of motion is critical.

The coupler is rated for a maximum speed of 5000 rpm and a torque of 41 Ncm, demonstrating its capability to perform reliably under dynamic conditions. The high torsional stiffness and quality of motion translation make it well suited for high-accuracy applications such as precision instruments, laboratory devices, and automation systems. Operating reliably within a wide temperature range of -50°C to 120°C, this coupler is designed to withstand challenging environments, including laboratory, manufacturing, and automation sectors.

Manufactured in France, the Huco 321.07.1414 complies with ISO 77, 774 (BS 45 Pt. 1), and BS 46 Pt. 1 standards, ensuring quality and performance. Its bellows material - electrodeposited nickel - further enhances resistance to fatigue, contributing to long-term service life. The moment of inertia is measured at 1.3 x 10-8 kg/m², supporting applications where minimal rotational resistance is essential.

Its robust construction and compliance to international standards confirm suitability for industrial, laboratory, and commercial use cases where precise mechanical power transmission and flexibility are required. Application areas include instrumentation drives, automation systems, industrial machinery, and control equipment.
