These headline parameters are specified on Siasun’s official product page and product listing partners.
Siasun’s industrial portfolio page also places the SR210-120/3.05 among its high-payload, long-reach series, next to variants oriented to 165–210 kg payloads and shorter reaches—useful when selecting between span and payload priorities.
With a 120 kg payload and long arm, the SR210-120/3.05 covers large infeed/outfeed areas and deep pallets, reducing external linear axes. Typical end-effectors include multi-function grippers, vacuum frames, and magnetic lifters.
The protected wrist and multi-orientation capability support arc welding, resistance welding, and thermal cutting in body-in-white and heavy-fabrication cells. Siasun case examples include automotive welding lines and shipbuilding solutions.
The robot’s reach allows dual-machine tending (e.g., CNC pairs) and deep-cell loading, where parts must be placed into fixtures beyond safety fencing or guarding.
For large subassemblies, the SR210-120/3.05 can position and hold components while tools apply screws, rivets or adhesive, benefiting from its repeatability when aligning to toleranced interfaces.
Extended reach with standard 6-axis kinematics — 3,053 mm span enables coverage across multiple stations or deep fixtures without external slides.
Balanced heavy-duty performance — 120 kg payload paired with ±0.08 mm repeatability suits both handling and process tasks.
Robust wrist sealing — IP65 wrist protection supports welding and cutting environments with particulates and coolant spray.
Flexible installation — floor or ceiling mounting expands cell layout options in brown-field retrofits.
Integration-ready — vendor messaging emphasizes ease of programming and commissioning to shorten ramp-up time.
What is the Siasun SR210-120/3.05?
A 6-axis articulated industrial robot with 120 kg payload and 3,053 mm reach designed for heavy material handling, welding, loading/unloading and assembly tasks.
How accurate is it?
The model is specified at ±0.08 mm repeatability, supporting precision placement and multi-pass process paths.
Why is the IP65 wrist important?
The IP65-rated wrist improves reliability in environments with dust, coolant and weld spatter, extending service intervals and protecting joints and cabling.
Where is the SR210-120/3.05 used?
Applications include automotive welding, metal fabrication, machine tending, material handling and assembly, often where long reach reduces external axes.
How is it installed and programmed?
It supports floor or ceiling mounting and is supplied with a user-friendly programming environment and tools for commissioning and debugging. Integration is usually performed by certified partners or in-house automation teams.
How does it compare to SR210A-210/2.65?
The 210/2.65 variant provides higher payload (210 kg) but shorter reach (2,658 mm), and a reach-down version for deep cavities; the 120/3.05 maximizes span while holding 120 kg payload. Choice depends on workpiece mass and cell geometry.
The Siasun SR210-120/3.05 is a long-arm, heavy-duty 6-axis robot that marries 120 kg payload and 3,053 mm reach with ±0.08 mm repeatability and an IP65 wrist. Its extended envelope allows coverage of multiple stations or deep fixtures without external axes, while installation (floor or ceiling) and integration tooling streamline deployment. For manufacturers balancing span, payload and precision in welding, handling and assembly cells, the SR210-120/3.05 offers a robust, integration-ready platform.
