SIASUN SR360A-360/2.83 (SR360A-360/2.83)

On a spot welding line, a robot is rarely judged on a single weld. It is judged on the rhythm it holds over a full shift, on how still the gun sits when it arrives at a joint, and on how seldom the line must stop for maintenance. The SIASUN SR360A-360/2.83 (SR360A-360/2.83) is engineered for that longer view. Its self-developed high-torque motors raise spot welding rhythm by more than 10%, while a backlash-free J5 gearbox and a counterweight-free body address stiffness and reliability, not lifting capacity alone. The result is a heavy-payload machine meant to be measured by the output of the cell around it.

Robots Middle East sells the SIASUN SR360A-360/2.83 and supplies it to manufacturers, system integrators and engineering institutions across the Middle East. Our team prepares each quotation against the customer's application. We coordinate delivery and customs clearance, and we remain the point of contact for technical support once the robot is installed and in production.

Background

SIASUN and its engineering lineage

SIASUN builds its robot range on more than two decades of engineering validation and thousands of project experiences. The company's stated approach is to deliver value-added services that combine robot products with their applications, rather than to supply an arm in isolation. That philosophy shapes this model. Its design choices respond to the conditions found in real production cells: repeated start-stop motion, heavy tooling, long operating hours and the need to integrate with equipment already on the line.

This lineage matters to a buyer in practical terms. A robot that comes from a manufacturer accustomed to project delivery tends to be specified with integration in mind. Communication interfaces, space in the cabinet and serviceability are treated as part of the product, not as afterthoughts for the integrator to solve.

Built for stiffness, rhythm and uptime

The SR360A-360/2.83 belongs to SIASUN's large-payload family, and three engineering decisions define it. First, the J5 axis uses a backlash-free gearbox, which raises overall rigidity and reduces vibration when the arm starts and stops. Second, the self-developed high-torque motors increase spot welding rhythm by over 10%. Third, the robot body has no counterweight, a choice intended to lower the failure rate.

Around the arm, the control cabinet supports mainstream communication protocols and reserves expansion space, including room for external axis drivers. That makes system integration and production line deployment more straightforward. Together, these features describe a robot designed less to impress on a single figure than to perform consistently inside a working line.

Technical Specifications

Specifications are as published by the manufacturer and are confirmed against the datasheet at quotation. The manufacturer has not published the weight, rated power, controller model, axis speeds, axis motion ranges, mounting options, operating temperature, power supply voltage or the contents of the delivery; Robots Middle East confirms these at quotation.

How does the SR360A-360/2.83 compare with the SR360A-280/3.20?

The SR360A series appears in two versions, and the clearest difference between them is payload. The SR360A-360/2.83 carries 360 kg (793.7 lbs) and reaches 2830mm. The SR360A-280/3.20 carries 280 kg (617.3 lbs). For a buyer, the choice therefore begins with the total mass at the wrist: the tool, the part and any dress pack or gripper hardware, plus a sensible margin for dynamic loads.

Where a heavy welding gun or a large casting pushes that total towards the upper end, the SR360A-360/2.83 is the version with the headroom. Where the load sits comfortably within the lower figure, the SR360A-280/3.20 is worth considering, and Robots Middle East can advise on which of the two suits a given cell.

Why does a counterweight-free, backlash-free design matter on a heavy robot?

Heavy robots spend much of their working life accelerating and stopping large masses. In general, any play in the drivetrain and any additional moving mass shows up as vibration at the end of a move. The tool then needs time to settle before it can weld, place or dispense accurately. By using a backlash-free gearbox on the J5 axis, SIASUN targets exactly that settling behaviour, raising rigidity and reducing start-stop vibration. Combined with a repeatability of ±0.01mm, this lets the robot arrive at a joint and work without waiting for oscillation to die away.

The counterweight-free body addresses a different concern: uptime. Fewer components in motion generally means fewer parts that wear and fewer points that require inspection, and the design lowers the failure rate. For a plant where a stopped robot can halt an entire body line, that reliability argument often weighs as heavily as any performance figure. The IP67-rated wrist adds protection where the tool meets the process, which is relevant in cells exposed to spatter, coolant or adhesive.

Who is the SIASUN SR360A-360/2.83 for?

The most natural buyers are automotive body shops and their tier suppliers, where spot welding with heavy guns is routine and cycle time translates directly into output. The higher spot welding rhythm and the rigid J5 axis address both of their central concerns: throughput and weld placement.

System integrators form a second group. Because the control cabinet supports mainstream protocols and reserves space for external axis drivers, the robot can be built into cells with positioners, tracks or conveyors without improvising cabinet space. Integrators assembling heavy handling, loading or gluing cells will find the same advantage.

A third group is general heavy manufacturing: metal fabrication, machinery building and plants that move large components between stations. For these users, the payload and reach allow one robot to cover tasks that might otherwise require lifting aids or manual handling. Buyers whose loads remain well within 280 kg (617.3 lbs) may be better served by the SR360A-280/3.20 version. Those comparing a wider set of options can browse the Large Payload category or the full range of Industrial Robots from SIASUN.

What is the SIASUN SR360A-360/2.83 used for?

1. Spot welding — carrying heavy welding guns through body-in-white sequences at a higher rhythm.
2. Heavy handling — moving large parts, fixtures and assemblies between stations within its payload.
3. Loading and unloading — tending presses, machine tools and conveyors with heavy workpieces.
4. Assembly — positioning substantial components where repeatability determines fit.
5. Gluing — guiding dispensing tools along seams, with an IP67-rated wrist at the process end.
6. Integrated multi-axis cells — working with positioners or tracks driven from the reserved external axis space in the cabinet.

Summary

The SIASUN SR360A-360/2.83 is best understood through the arithmetic of a production shift rather than a single headline figure. A payload of 360 kg (793.7 lbs) and a reach of 2830mm give it the capacity for heavy tooling. The benefit compounds over time, however: spot welding rhythm raised by more than 10%, a backlash-free J5 axis that settles quickly, a counterweight-free body designed for fewer failures, and a control cabinet prepared for integration. For body shops, integrators and heavy manufacturers in the region who want those gains in their own cell, with delivery and support arranged by Robots Middle East, this page is the starting point.
