The metal bellows coupling of the KP series with 4-shaft bellows and two radial clamping hubs is a version with short overall length in the JAKOB coupling program. This makes it particularly suitable for applications with minimum shaft distances and limited installation conditions. In addition, the very high torsional stiffness and the installation-friendly clamping hub design are worth mentioning. A low moment of inertia as well as good values for the permissible shaft misalignments and restoring forces round off the overall package.

The multilayer metal bellows made of certified stainless steel is characterized on the one hand by its high torsional stiffness and on the other hand by the compensation of axial, radial and lateral shaft misalignments. The shortened design and the resulting weight savings result in further advantages such as lower mass moments of inertia.

The clamping hub is made of high-strength aluminum to achieve the lowest possible mass moment of inertia. The hubs are equipped with the innovative and service-friendly Easy-Clamp system. It guarantees simple sliding on with sufficient fitting clearance. A single, radially easily accessible screw per hub provides the preload force required for torque transmission. Thanks to this simple but very reliable connection, the couplings can be installed in just a few steps, even in difficult installation conditions.

The bellows-hub connection is made using the optimum and backlash-free flare press-fit process. In contrast to adhesive connections, this joining method has absolutely unlimited fatigue strength under critical operating conditions (-40°C to +200°C, chemicals) and the transmission torque of each individual bellows layer is safely transferred to the hub.

The KP series is available for nominal torques from 25 to 900 Nm with bore diameters from 10 - 75 mm.
