Laifual FH series (FHD/FHN/FHG/FHT) features a through-bore hollow shaft for central cable and shaft routing, sizes 8-40 with 50-160 ratios, 1.25-382 N·m rated torque, momentary permissible torque up to 1530 N·m, backlash ≤20 arcsec, angular transmission accuracy down to 1 arcmin and 8000-15000 h design life; the output flange integrates a cross-roller bearing (CRB) to carry external moment loads directly, with FHD-14 weighing only 0.34 kg, fitting humanoid waist/shoulder/elbow joints, precision rotary tables and optical equipment.
Laifual (03952.HK) FS series are standard harmonic component sets in FSF, FSS, FSN and FSG structures, sizes 5-50 with 50-160 ratios, 0.4-529 N·m rated torque at 2000 r/min input, momentary permissible torque up to 2450 N·m, backlash ≤20 arcsec, angular transmission accuracy down to 1 arcmin, 10000-15000 h design life and a lightest weight of only 25 g, benchmarking Harmonic Drive CSF/CSG/CSD for humanoid/collaborative robot joints and precision automation.
Huandong Technology, the robot-joint reducer arm of Shuanghuan Driveline, covers robots from 3 to 1000 kg payload. The SHPR-E precision cycloidal (RV) series' representative SHPR-20E offers a 57/56 ratio, 153 N.m output at 20 r/min, 412 N.m start-stop torque, 833 N.m peak torque, 1 arc.min backlash and 4.7 kg weight for industrial robot and automation joints.
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.
The CSD-2A is Harmonic Drive’s ultra-compact gear component set: shortest design, low weight and a large hollow shaft for cables and shafts, ideal for tight installation spaces. Official data: ratios 50/80/100/120/160 with repeatable peak torques 12-823 Nm, hollow shaft Ø11-50 mm, sizes 14-50; reduced moment of inertia for high dynamics, ideal with integrated output bearing arrangement.
