ROBA®-ES: Backlash-free, vibration-damping, plug-in and maintenance-free shaft coupling

Torsionally flexible
Pluggable
Compensation of shaft misalignment
Vibration damping
Suitable for blind mounting

Configure now

ROBA® -ES couplings connect shafts in highly dynamic servo drives. They transmit torques elastically and backlash-free. Single-jointed couplings (type 940.___) compensate for axial and angular misalignment, double-jointed couplings (types 942.___ and 943.___) also compensate for radial misalignment.
