Product Description

The LHSG high-torque hollow-shaft flexspline strain wave gear uses high-rigidity bearings and an overall strengthened design to increase the torque carrying capacity by more than 30% compared to the LHS harmonic speed reducer standard series. In addition to reducing the weight of machinery and equipment, the decrease in the weight of industrial robots can increase the robot's speed and payload weight.
