LSN Light Weight Harmonic Drives

Compared with the LSS series of small harmonic drives, LSN harmonic reducer is with the same structure and performance as LSS harmonic reducers. The only difference and advantage is lighter weight, the weight of LSN is 30% lighter. This is because we change the circular spline's material from steel to aluminium alloy.
