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

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

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.
