The GR series is a precision speed reducer from Mitsubishi Electric designed for mounting on servo motors, increasing output torque and matching load inertia. Reduction lets a smaller servo motor drive larger loads while keeping positioning accurate. It is used on servo axes in robots, indexing tables and packaging machines.
