This document provides technical specifications for the GERWAH AK series backlash-free metal bellows couplings. It includes dimensional data for various sizes, material composition (stainless steel bellows, aluminum or steel hubs), and ordering information.
The datasheet details performance characteristics such as nominal torque, torsional stiffness, radial and axial spring stiffness, and maximum rotational speed. It also specifies maximum approved misalignment values for axial, angular, and radial directions, along with tightening torque requirements for the screws. This manual is written in German.
| Material Bellows | Stainless steel |
|---|---|
| Material Hubs (up to size 500) | Aluminum |
The metal bellows are made of stainless steel.
The shaft tolerance should be within the fit tolerance "g6" or "h7".
