lsg harmonic reducer

LSS High Precision Harmonic Gearbox

The LSS series of micro harmonic reducers can be divided into two models depending on the different used harmonic waveform generators: LSS-I (uni-body type wave generator) and LSS-II (cross slider type wave generator). We provide 6 different sizes with 5 kinds of speed reduction ratios according to clients' various applications and requirements. The LSS series of harmonic reducer is a combination series that is easy to operate. Standard servo motors can be attached in a compact manner. Each model contains a cross roller bearing with high rigidity to support external loads.
