- 17% higher overall rigidity A breakthrough forward-designed, all-new backlash-free five-axis gearbox structure increases whole-machine rigidity by 17% for stable heavy-duty operation.
- 125 kg payload with 3100 mm reach Long-reach coverage combined with a 125 kg payload lets the robot serve large workpieces and widely spaced stations from a single mounting position.
- Faster, smoother motion planning NURBS transitions with variable-speed, variable-acceleration planning enable faster and more stable operation, improving spot-welding cycle time by over 11%.
- Custom high-inertia wrist motor SIASUN's own-brand high-inertia motor delivers superior wrist torque performance and increases the allowable end-effector inertia by 8%.
- IP54 machine, IP67 wrist protection A customized aviation-plug sealed cover achieves IP54 protection for the whole machine and IP67 at the wrist for harsh production environments.
- ±0.06 mm repeatability Six-axis precision with ±0.06 mm repeatability supports accurate handling, assembly, vision inspection, and spot-welding work.
Description
The SIASUN SR220A-125/3.10 is a six-axis industrial robot built around a high-rigidity structure, with overall machine rigidity improved by more than 17% thanks to a breakthrough forward-designed, backlash-free five-axis gearbox. It carries a 125 kg payload across a long 3100 mm reach with ±0.06 mm repeatability, while a custom high-inertia wrist motor from SIASUN's own brand raises the allowable end-effector inertia by 8% for demanding tooling. Optimized dynamic algorithms with NURBS transitions and variable-speed, variable-acceleration motion planning make operation smoother and faster — improving spot-welding cycle times by over 11% — and a customized aviation-plug sealed cover achieves IP54 protection for the whole machine with IP67 at the wrist.
In production, the SR220A-125/3.10 covers handling, assembly, vision inspection, loading and unloading, and spot welding, and the series offers a range of load capacities and arm reaches to match diverse application scenarios. SIASUN documents the platform in real production deployments including automotive welding assembly lines, LCD TV manufacturing solutions, teach-free welding cells, automated carton palletizing, flexible welding workstations, and intelligent welding systems for ships and engineering machinery.
