Robot arm & cobot joints

High-ratio joint modules (harmonic, cycloid and high-reduction planetary) for arms that need stiffness, precision and holding torque.

  • High ratios give stiffness and holding torque but are hard to backdrive.
  • Check whether a brake is available for joints that hold a load at rest.
