Precision Couplings Range Offer Reliable Torque Transmission with Improved Torsional Stiffness

Tsubakimoto Chain, the world”s premier manufacturer of power transmission products, has developed a comprehensive series of precision couplings capable of delivering reliable torque transmission with improved torsional stiffness. The Echt-Flex series consists of a wide range of couplings designed for ease of installation and capable of handling even the largest of shaft diameters.

Tsubaki has a long history in the development and refinement of power transmission products and development of the Echt-Flex series has involved finite element analysis to produce a zero backlash coupling capable of an extended service life. The comprehensive series incorporates a variety of designs including long spacer types, which can be dynamically balanced by Tsubaki for applications which require high rotational speeds.

Within the Etch-Flex series is a number of product ranges designed to meet specific application requirements. The NES range provides small, precision couplings designed for high torsional stiffness and a low moment of inertia. These make ideal connection components for servo motors and stepper motors used in industrial robots and precision equipment.

The NEF range is based on a spacer type coupling comprising two sets of disk kits which enables the coupling to accommodate shaft misalignment. The range can be specified with a variety of shaft connection types, including the single bolt clamp which enables a friction coupling to the shaft, reducing the axial dimension and saving installation space.

For larger applications, the NEH range is designed as a spacer type coupling capable of handling up to 176,400 Nm. This range can be specified with an adapter hub type coupling which provides a larger bore diameter or with a unit spacer type coupling which can be mounted or removed without having to disassemble the disk connecting section.

Derek Mack, Sales Director for Tsubaki UK, comments: “Tsubaki is dedicated to manufacturing power transmission solutions for its customers that will improve productivity and offer industry leading reliability. The Echt-Flex Series of couplings offers a choice of specifications to suit specific requirements and is designed to provide excellent precision, reliability and performance.”

As a leading manufacturer of power transmission components with a reputation for delivering reliable and cost effective solutions, Tsubaki understands well that the performance of drive couplings is crucial to the overall precision and reliability of the equipment on which it is installed.

The complete range is supported by a comprehensive catalogue which gives full specifications of each series and a complete selection guide to help customers select exactly the right product for their application. In addition, the catalogue includes full dimensional information for each model and detailed installation and removal instructions to ensure an exact fit and reliable operation.
