Featured Products

Servo Couplings

  • For high performance servo motor motion control applications
  • High torsional stiffness for precision positioning
  • Eco-Friendly servo motor couplings, Adapted to RoHS Directive with no banned substances
  • Low inertia for high speed applications (low runout)
  • Zero backlash and low hysteresis ensures repeatable precise positioning
  • Servo Motor Shaft Couplings for Clean Room Applications

Flexible Shaft Couplings

  • High parallel, angular, and axial shaft misalignment capabilities with considerably less sideloads on shaft bearings. These features increase the lifetime of other machine components.
  • Zero backlash design, which is required for precision drives.
  • Electrically isolating flex element which increases lifetime of other machine components.
  • Low weight and inertia reduces power requirements.
  • Clamp-Style hubs provide a secure shaft connection for precision drives
