Particularly powerful high-speed variants are suitable for applications with extreme dynamic requirements. Spread cone designs offer secure and backlash-free clamping on hollow shafts without the need for additional components. Pluggable versions for blind mounting facilitate installation on hard-to-reach shafts without compromising the precision of the coupling.
Metal bellows couplings are used in a wide range of industries, including automation, robotics, aerospace, and mechanical and plant engineering. They impress with maximum operational reliability, long service life, and high repeatability in continuous operation, offering the technically optimal solution for every application.
