Metal Bellows Couplings
ENEMAC metal bellows couplings connect two shafts completely backlash-free and torsionally rigid and are used in direct drives. The flexible metal bellows reliably compensates for axial misalignment, radial misalignment, and angular misalignment, thus protecting bearings and other components from overload. Thanks to simple and quick installation, the couplings ensure reliable torque transmission even at high speeds and temperatures up to 350°C.
Particularly powerful high-speed variants enable speeds of up to 57,000 rpm and 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.
ENEMAC 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.
