SIASUN Industrial Robot Arm with 2658 mm Reach, 210kg Max Payload, 6 DOF (SR210A-210/2.65)
The SIASUN Industrial Robot Arm with 2658 mm Reach, 210kg Max Payload, 6 DOF (SR210A-210/2.65) is a heavy-duty six-axis articulated robot built for high-payload production work, with a manufacturer-stated specialization in spot welding. It combines a 210 kg maximum payload with a 2,658 mm reach, a reinforced wrist design delivering high torque output, and double-sealed critical components intended for long, uninterrupted duty cycles. This page consolidates what manufacturer materials and datasheet listings document about the SR210A-210/2.65, outlines where it fits on a production line, and explains how to obtain a quotation.
Background
The SR210A within SIASUN's heavy-payload range
SIASUN is a Chinese industrial robotics manufacturer with a portfolio spanning articulated arms, mobile platforms, and full automation systems. The SR210A-210/2.65 sits in its heavy-payload six-axis class, where the company offers configurations that balance payload against reach — this model carries the full 210 kg rating at a 2,658 mm span, while long-arm siblings extend past three metres at reduced payload. Manufacturer copy presents the SR210A as a widely applied, high-flexibility heavy-duty robot with optimized dimensional design and energy efficiency, positioned as a cost-effective option for demanding cells. The company's stated design emphasis for this model is the wrist: a robust, high-torque wrist assembly credited with improving both speed and payload performance, which is the mechanical foundation for its spot-welding orientation.
Why spot welding drives heavy-payload robot design
Automotive body shops remain one of the largest consumers of heavy six-axis robots, and spot welding is their defining task. A servo spot-welding gun with its transformer, cabling, and dress pack is heavy, and the robot must swing that mass quickly between weld points while holding position precisely at each one. That is why payload, wrist torque, and repeatability dominate the specification sheet for robots in this class. SIASUN's messaging for the SR210A-210/2.65 tracks this logic directly: high torque output at the wrist for speed and load capacity, enhanced sealing on key components for durability in weld-shop conditions, and a control system designed to talk to welding guns and weld controllers from multiple brands so that integrators are not locked into a single equipment ecosystem. The same attributes — payload headroom, torque, and sealing — carry over naturally to handling and machine-tending duties.
Technical Specifications
| Parameter | Value |
|---|---|
| Robot type | 6-axis articulated industrial robot |
| Maximum payload | 210 kg |
| Maximum reach | 2,658 mm |
| Repeatability | ±0.06 mm (third-party datasheet listing) |
| Wrist design | Reinforced, high-torque output (manufacturer) |
| Sealing | Double-sealed critical components (manufacturer) |
| Control system | SIASUN self-developed intelligent control system; stated compatibility with multi-brand welding guns and controllers |

Payload and reach appear in both manufacturer and third-party materials; the ±0.06 mm repeatability figure comes from a third-party datasheet listing and, like all values here, should be confirmed against the current official SIASUN datasheet during quotation.
What makes the SR210A-210/2.65 suited to spot welding?
Three documented characteristics align this model with spot-welding duty. First, the payload: 210 kg provides headroom for heavy servo weld guns with transformers and dress packs, plus the reserve capacity that fast gun transport between weld points demands. For integrators, multi-brand compatibility reduces the risk of being forced into a specific gun or weld-timer vendor when retrofitting existing lines. Actual gun models, weld-controller integrations, and process package contents are configuration items to be confirmed with the supplier during project engineering.
How durable is the platform in continuous production?
Manufacturer materials emphasize durability engineering rather than quoting service intervals: critical components use a double-sealed structure described as delivering exceptional durability, and the robot is stated to be built from high-quality materials and components subjected to rigorous testing for prolonged, uninterrupted operation with reduced downtime and maintenance cost. In weld shops, sealing matters because expulsion spatter, dust, and shop contamination attack joints and cable entries first. The company also cites advanced drive technologies and precision manufacturing as the basis for accuracy and stability across complex tasks.
Who is the SIASUN SR210A-210/2.65 for?
The SR210A-210/2.65 targets manufacturers and system integrators whose cells are payload-driven: automotive OEMs and tier suppliers running spot-welding lines, metal fabricators moving heavy weldments or castings, foundries and forges tending presses and machining centres with parts and tooling approaching the 200 kg class, and general industry handling dense subassemblies across a roughly 2.6-metre envelope. It also suits retrofit programmes where multi-brand welding-gun compatibility simplifies integration with existing weld controllers.
What is the SIASUN SR210A-210/2.65 used for?
- Spot welding — transporting and positioning heavy servo weld guns across body-in-white and sheet-metal assemblies, the application SIASUN identifies as the model's specialization.
- Heavy material handling — lifting and transferring parts up to the rated payload between stations, conveyors, and fixtures using integrator-specified grippers or magnetic and vacuum tooling.
- Machine loading and unloading — tending presses, casting machines, and CNC machining centres with heavy parts and tooling on repeatable cycles.
- Assembly of large subassemblies — positioning and holding heavy components at toleranced interfaces while fastening or joining operations are performed.
- Palletizing of dense goods — stacking heavy cases, sacks, or components where per-cycle mass rules out lighter robot classes.
- Multi-process flexible cells — combining handling and welding duties in one cell using the manufacturer's stated multi-industry process packages, subject to configuration at quotation.
Pricing and Availability
Robots in the 210 kg payload class are sold as configured systems, so pricing depends on the controller cabinet, teach pendant, software and process packages, dress pack, welding-gun integration, safety hardware, shipping terms, and commissioning scope for the destination site. Availability and lead times likewise vary by configuration and region. To obtain current pricing for the SR210A-210/2.65, submit a request for quotation describing your application — process type, part mass including tooling, cycle expectations, and installation country — and a detailed proposal will be prepared, including alternatives from the same SIASUN heavy-payload series if the application profile suggests a different payload-reach balance.
