Compact classic with clamping hubs

The KP series metal bellows coupling is characterized by its short design and a 4-corrugated bellows with two radial clamping hubs. This compact design is ideal for applications with minimal shaft spacing and limited space. The high torsional rigidity and simple installation thanks to the clamping hub design are particularly noteworthy. The coupling also offers a low moment of inertia and good values for permissible shaft misalignments and restoring forces.

The multi-layer metal bellows made of certified stainless steel offers high torsional rigidity and compensates for axial, radial and lateral shaft misalignments. The shortened design saves weight, resulting in a lower mass moment of inertia.

The clamping hub is made of high-strength aluminum to keep the mass moment of inertia as low as possible. With the innovative Easy-Clamp system, the hubs can be slid on easily and with sufficient fitting clearance. A single, radially easily accessible screw per hub provides the necessary preload force for torque transmission. This simple yet reliable connection enables the clutches to be fitted quickly, even in difficult installation conditions.

The connection between the bellows and hub is made using an optimum, backlash-free crimping process. In contrast to adhesive connections, this joining process is absolutely durable under critical operating conditions (-40°C to +200°C, chemicals) and guarantees reliable transmission of the torque of each individual bellows layer into the hub.

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