Specifications:
The document provides detailed specifications for the EKHZ series of elastomer couplings with intermediate pipes. Key parameters include torsional stiffness, moment of inertia, maximum speed, and mass for various sizes ranging from 20 to 1600 Nm. The maximum axial shaft misalignment is ±1 mm, and the maximum lateral shaft misalignment is 5 mm per meter of overall length. The temperature range is from -30°C to +90°C.

Technical Data:
The technical data section outlines the dimensions and torque specifications for each size. Sizes range from 20 to 1600, with corresponding dimensions and tightening torques specified. The document also includes details on the material composition, with hubs made from high-tensile aluminum or steel, intermediate pipes from aluminum precision pipe, and elastomer spiders from PUR-72 Sh-D.

Features:
The EKHZ couplings are described as having variable lengths up to 3 meters, being plug-in, backlash-free, oscillation dampening, rust-proof, and featuring a split-hub design for simple installation.

Order Example:
An example order is provided for the EKHZ 90 model, specifying dimensions and tolerances according to DIN ISO 2768 cH standards.

Materials:
The document specifies the materials used for different components, including high-tensile aluminum for most hubs, steel for size 1600, and coated screws conforming to ISO 4762 / 12.9 standards.
