The reducer has a shaft with a bearing at the input

LHS / LHSG series harmonic gearboxes
- are based on super compact technology with a large hollow shaft,
- have zero backlash and excellent accuracy and repeatability.
- Simplicity – compact dimensions and light weight
- The output bearing with high tilting stiffness allows direct introduction of high loads without additional support, thus enabling simple and space-saving design installations.
- The LHS units are characterised by their very compact dimensions and low weight, consisting of a set of components and a large-capacity output bearing. The absence of inlet and outlet flanges means maximum flexibility in design integration.
- The integrated hollow shaft can be used as a line feed or for cables for other axes.
- The LHS-XXX-P component set can be directly integrated into your machinery/equipment.
