Metal bellows couplings
Servo couplings are compensating couplings for the backlash-free, true-angle transmission of torque with the highest possible torsional rigidity and the lowest possible mass moment of inertia. In line with this claim, JAKOB metal bellows couplings can be regarded as the ideal solution. They have already proven themselves in numerous servo drives for over 40 years. The elastomer couplings with a flexible polyurethane spider can also be a sensible alternative for many applications due to their specific advantages.
Metal bellows couplings are highly flexible all-metal couplings with high torsional rigidity and minimal mass moments of inertia. Cone and clamp connections are available, as well as various metal bellows shapes for a wide variety of applications. What all JAKOB servo couplings have in common is the absolute freedom from play (also shaft-hub connection) and the flexibility to compensate for shaft misalignment. Due to the respective unique selling points of the individual series, the designer will always succeed in finding an optimal solution from the extensive JAKOB coupling range. The areas of application range from highly dynamic feed axes of machine tools to demanding drives in general mechanical engineering.
