It has proven itself on the market for decades and is a tried and tested standard series of metal bellows couplings: The metal bellows coupling KM from JAKOB Antriebstechnik. Like all metal bellows couplings, it is stiff in the direction of rotation, but flexible in the axial, angular and radial directions. Despite the similarities, however, metal bellows couplings sometimes differ greatly from each other. The technical differences are, for example, in the choice of the bellows or the connection of bellows and hub or bellows and shaft. JAKOB uses only thin-walled, multi-layered bellows made of certified stainless steel sheets. This causes a high torsional stiffness, which ensures high positioning accuracy and concentricity even under difficult conditions, which guarantees absolutely backlash-free torque transmission between the input and output shafts. The multi-layer bellows design also causes the absorption capacity of large shaft displacements with still small restoring forces. This means an increase in reliability, safety and service life.

The clamping hub of the KM is equipped with the innovative Easy-Clamp-System, which allows a simple, with enough fit clearance, sliding. The necessary preload force for torque transmission is ensured here by a single, radially accessible screw per hub. This simple and reliable connection allows uncomplicated installation in a few steps, even in confined spaces. To achieve the lowest possible moment of inertia, the hubs are made of high-tensile strength aluminum.

The bellows and hubs are connected using the brass-wire press-fit method. In contrast to adhesive bonds, this joining process has unlimited fatigue life under critical operating conditions (-40 ° C to + 200 ° C, chemicals, etc.) and can safely introduce the transmission torque of each bellows layer into the hub.

KM series metal bellows couplings are available with nominal torques from 0.4 to 1300Nm.

About JAKOB Antriebstechnik GmbH

JAKOB Antriebstechnik GmbH is an internationally leading manufacturer of servo couplings, safety couplings, and mechanical clamping elements. For more than 40 years JAKOB has been developing and producing various types of torsionally stiff metal bellows couplings and safety couplings for the servo drive industry. Throughout our history we have earned ourselves a reputation of being a reliable and competent partner in the motion and drive industry.

JAKOB is the market leader in the area of mechanical tool and component clamping with its innovative and unique clamping technology.

The JAKOB wedge clamping technology provides the highest clamping forces with low actuation torques and, at the same time, maximum operational safety. The goal of our servo and safety coupling catalog is to provide a general overview over our standard product range. Highly trained engineers and technicians at our facility in Kleinwallstadt are always ready with a solution to best meet your requirements.
