LHT-8 and LHT-11 are two newly developed small products of LHT series, which are mainly characterized by lightweight and flat structure design. The flexspline is a standard structure of hollow flanging, and the output side is assembled with high-rigidity cross roller bearings. LH miniature harmonic gearbox series are ideal for small robots or devices that require an ultra-compact solution.
