LSS/LSG/LSN Standard Type/High Torque/Light Weight Harmonic Gearbox

Zhejiang Laifual Drive Co., Ltd. is one of professional laifual manufacturers.
We provide LSD Shorten Thin Harmonic Gearbox, LFS Ultra Flat Harmonic Gearbox,
planetary reducer gearbox and so on. Want to know more? Please contact us.

The LSS series of micro harmonic reducers can be divided into two models
depending on the different used harmonic waveform generator: 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 micro harmonic drive
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.
