Leaderdrive (688017.SH), China's leading strain wave gear maker, offers the LCS/LCSG standard cup-shaped series built from flexspline, circular spline, wave generator and roller bearings: sizes 14-58 with 30-160 ratios, 4-969 N·m rated torque and up to 4459 N·m momentary (LCSG high-torque version ~30% above LCS), backlash ≤10 arcsec, angular transmission accuracy down to 1 arcmin, input speeds to 8500 r/min and torsional rigidity up to 71×10⁴ N·m/rad, for robots, humanoids, semiconductor/PCB equipment, machine tools and photovoltaic machinery.
Ultra-flat strain wave gear built for tight axial space, about 50% shorter than the standard LHS/LHSG series, with a large hollow bore for cable routing. It keeps high rigidity, ultra-low backlash and strong load capacity across frame sizes 14-40 and ratios 50-160, rated 3.7-206 N·m, for humanoid robots, robot joints, PCB equipment and machine tools.
