Datasheet KR

Product catalog summary

Overview: The document provides technical specifications and details for metal bellows couplings, specifically the KR series, used in drive technology. These couplings are designed for simple installation with lateral EASY-clamping hubs, offering low restoring forces and high torsional stiffness.

Specifications: The couplings are made with stainless steel bellows and high-tensile strength aluminum hubs. They are suitable for a temperature range of -40°C to +200°C. The dimensions follow DIN ISO 2768 cH standards.

Technical Data: The document includes detailed tables listing the moment of inertia, torsional stiffness, maximum shaft misalignment, axial and lateral spring rates, and tightening torque of screws for various sizes (e.g., KR 25, KR 50, KR 100, etc.). The maximum rotational speed (nmax) varies from 7000 upm to 20000 upm depending on the size.

Order Examples: Examples are provided to illustrate how to specify orders, such as KR 100 - D1 = 35 G7 D2 = 35 G7.

Notes: There is a note on reduced tightening torque for larger hub bore diameters, and the variable length with bigger clamping hub size is indicated as L*.

Dimensions: The document provides a detailed table of dimensions for each coupling size, including parameters like Øa, c, f, g, h, L, L*, and mass.
