PGH220 Stage 1

Product features: high precision, high torque, high rigidity, high efficiency, high stability, low noise, low backlash.

Product introduction: It can be used with stepper motors or servo motors to reduce speed, increase torque, increase motor rotor inertia, improve rigidity, shorten start and stop positioning time, miniaturize motor power, and improve inertial load stability and reduce vibration. Single-stage can reach within 3 arc minutes, and double-stage can reach within 5 arc minutes.
