Fully Sealed High Torsional Stiffness Strain Wave Reducer
Product Description
LHG - IV is know as the fully sealed structure higher torque harmonic reducer. It is suitable for different input forms and easy to install.
The capable of bearing torque of LHG- IV series is over 30% more than standard LHT series. Its flexible wheel adopts a hollow flanged cylindrical structure, and the wave generator cam comes with an input shaft, and particularly suitable for applications requiring the installation of umbrella gears or synchronous belt drives at the input end.
