Metal bellow couplings

Metal bellow couplings are ideal in applications where precise positioning and control of machine components are required.  Their high torsional strength ensures accurate transmitted speed, angular positioning, and torque.

The metal bellow couplings are particularly suitable for direct connection between two coaxial shafts. The metal bellows compensate for lateral, axial, and angular shaft misalignment with low recovery forces. The backlash-free, inflexible metal bellows of high torsional strength guarantee precise positioning of the driven load and can be used in applications with high dynamic cyclic operations and at extremely high rotational speeds.

Metal bellow couplings from KBK

Metal bellow couplings

From KBK Antriebstechnik we offer metal bellow couplings that are absolutely backlash free and with high torsional strength. They are maintenance-free, and have high fatigue strength and low restoration forces due to incorrect adjustment. The modular system makes it possible to find a suitable coupling for any mounting situation.
