Precision couplings cover a wide range of applications

21 December 2014

Tsubakimoto Chain has introduced a series of precision couplings capable of delivering reliable torque transmission with improved torsional stiffness.

The Echt-Flex series comprises a variety of designs, including long spacer types, which can be dynamically balanced by Tsubaki for high rotational speed applications.

Within the Etch-Flex series is a number of product ranges, including the NES range, which provides small, precision couplings with high torsional stiffness and a low moment of inertia, suitable for servo motors and stepper motors.

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 176,400Nm. 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.
