SIASUN Industrial Robot Arm with 2833mm Reach, 360kg Max Payload, 6 DOFs (SR500A-360/2.83)

Lifting a heavy load is rarely the hard part of heavy-load automation. Setting it down in exactly the same place, cycle after cycle, is the real test. A forging that must enter a die squarely, or a pair of welding tongs that must close on the same seam on every body, will expose any arm that flexes under its burden. The SIASUN Industrial Robot Arm with 2833mm Reach, 360kg Max Payload, 6 DOFs (SR500A-360/2.83) is SIASUN's response to that tension: a 360 kg payload carried on a rigid arm structure that holds a repeatability of ±0.1mm across a reach of 2833mm.

Robots Europa, based in Dublin, supplies the SR500A-360/2.83 to manufacturers, system integrators and industrial research facilities throughout the European Union and the DACH region. Robots Europa prepares each quotation around the cell in which the robot is to work, arranges delivery to site and remains your point of contact for technical support once the arm is in production.

Background

SIASUN and its industrial lineage

SIASUN is a Chinese robotics and automation manufacturer with roots in the country's national research community for automation. Over time it has developed a broad portfolio that extends from industrial robot arms to mobile robots for intralogistics and complete automated production systems. Its industrial arms are organised by payload class, ranging from compact models intended for light assembly and handling up to the Ultra-High Payload group, in which SIASUN lists the SR500A-360/2.83. Within that group the emphasis shifts from speed and compactness towards strength, stiffness and the ability to cope with demanding production surroundings.

Rigidity as the key technology

The SR500A-360/2.83 pairs an all-new exterior design with a rigid arm structure and a high-performance transmission. That structural approach increases load capacity and broadens the range of tasks the robot can take on. It also delivers a fast overall cycle time and a 50% improvement in repeatability compared with the previous generation. For a heavy-payload arm, this is the decisive point: stiffness is what allows a large mass to be moved quickly without sacrificing the accuracy of the final position.

What does the rigid structure change compared with the previous generation?

In heavy-load robotics, there is usually a trade-off between the mass an arm can carry and the precision with which it carries it. A heavier payload loads every joint and link, and any deflection in the structure appears at the tool as positional error. SIASUN has addressed this on the SR500A-360/2.83 by redesigning the arm around a rigid structure and combining it with a high-performance transmission.

The result is a 50% improvement in repeatability over the previous generation, with the arm now returning to a taught point within ±0.1mm. That figure matters most in processes where the robot holds a heavy tool against a workpiece, such as spot welding with tongs, or where a bulky part must be presented to a press or die in a consistent orientation. The same stiffness also supports a fast overall cycle time, because a rigid arm settles more quickly at the end of a movement and spends less time waiting before the next step can begin.

For production planners, this means the SR500A-360/2.83 is not simply a stronger arm but a more predictable one. Predictability reduces rework, simplifies process tuning and makes it easier to keep a heavy-load cell running at a steady rhythm across shifts.

Can the SR500A-360/2.83 work in dusty and outdoor environments?

Heavy-load robots tend to be deployed precisely where conditions are least forgiving: foundries, forging shops and welding lines, where dust, spatter and fumes are part of daily operation. The SR500A-360/2.83 is designed for such harsh production environments and operates reliably both indoors and outdoors, including where dust levels are high.

The wrist, which sits closest to the process and is therefore most exposed, carries IP67 protection. In practice, this gives the integrator more freedom in where the cell is placed and how much additional shielding it needs.

Who is the SR500A-360/2.83 for?

The SR500A-360/2.83 is aimed at organisations whose processes involve heavy tools or heavy parts and who cannot afford to lose accuracy because of that weight. Foundries and casting plants form a natural first group, as the arm was developed specifically for high-efficiency, heavy-load work in casting. Forging operations are a second, since the robot can precisely manipulate large, bulky and heavy parts during the forging process.

Automotive manufacturers and their tier suppliers form a third segment. In body shops and component plants, the arm can carry heavy welding tongs or work with heavy components, tasks that place sustained loads on the wrist and the main axes. A fourth group includes heavy fabrication and material handling operations, where large items must be moved between stations reliably and at a consistent cycle time.

System integrators building turnkey cells for any of these sectors will also find the SR500A-360/2.83 relevant, particularly when a project calls for a combination of long reach, high payload and a protected wrist. Where the loads in your application are considerably lighter, a smaller arm from the SIASUN range may be more economical, and Robots Europa will be pleased to advise on the most suitable model as part of your enquiry.

What is the SR500A-360/2.83 used for?

1. Casting: handling heavy castings and tooling in foundry cells where dust and heat are constant.
2. Welding: carrying heavy welding equipment along seams that demand consistent positioning.
3. Automotive spot welding: holding heavy welding tongs on body-in-white lines with repeatable accuracy.
4. Automotive component handling: moving and presenting heavy components between stations in vehicle production.
5. Forging: precisely manipulating large, bulky, heavy parts in and out of forging processes.
6. Heavy material handling: transferring large loads in production areas indoors or outdoors, even where dust levels are high.

Summary

Heavy-load automation succeeds or fails on what happens at the end of the movement, when a large mass has to come to rest exactly where the process needs it. The SR500A-360/2.83 addresses that challenge with a rigid arm structure and a high-performance transmission, combining a 360 kg payload and 2833mm reach with a repeatability of ±0.1mm, a 50% improvement over the previous generation. Its IP67 wrist and its suitability for dusty indoor and outdoor environments make it a strong candidate for casting, forging, welding and heavy material handling, as well as for automotive lines that rely on heavy welding tongs.
