SIASUN SR500A-360/2.83 (SR500A-360/2.83)

Most robots are chosen for what they can lift. Far fewer are chosen for what they can lift while still reaching the far side of the workpiece. The SIASUN SR500A-360/2.83 (SR500A-360/2.83) was built around that second demand: a heavy-duty arm with an exceptionally large working envelope, meant for plants where parts are big, tools are heavy and the floor is not a clean room.

The product is available through this page, by quotation.

Background

The SIASUN brand and the SR500A family

SIASUN is an industrial robot brand, and its range is divided by payload class. At the light end sit models such as the SR12A-12/1.46 and the SR25A-25/1.80, which belong to the small payload range. At the heavy end sits the SR500A series, which the manufacturer developed specifically for heavy-load tasks. Two versions of the series are named in the sources: the SR500A-360/2.83 described here, and the SIASUN SR500A-500/2.52.

The SR500A-360/2.83 is described by the manufacturer as the successor to a previous generation. It brings an all-new exterior design and a rigid arm structure, and these are credited with raising load capacity and widening the range of applications. Buyers who are comparing heavy robots across the brand can also browse the Ultra High Payload category.

Positioning and key technology

The robot's character comes from two things working together: a highly rigid structure and a high-performance transmission. According to the manufacturer, this pairing delivers a fast overall cycle time and a 50% improvement in repeatability compared with the previous generation. Rigidity matters in a heavy robot because a long, loaded arm tends to flex, and flex costs accuracy. A stiffer arm lets the robot hold its path with a heavy tool at the end of it.

The second idea is working depth. The wide range of motion and the flexible joint structure allow the arm to work deeper into a cell. This expands the usable workspace and improves the flexibility and efficiency of the production line. The wrist carries IP67 protection, and the robot is built for harsh production settings, indoors or outdoors, including places with high dust levels. It is paired with the SRC L5 controller.

What makes the SR500A-360/2.83 different from a general-purpose robot?

A general-purpose arm is designed to be adequate across many jobs. This one is designed for a narrow, demanding group of jobs, and that focus shows in the figures. A payload of 360 kg (793.7 lbs) puts it in a class where the load is not a small tool but a welding tong, a casting or a forged part. A reach of 2833mm gives it room to carry those loads across a large cell without the integrator having to move the robot or the work.

Repeatability of ±0.1mm is the figure to read alongside the payload. Heavy robots are often assumed to be coarse, but this one is stated to be 50% better in repeatability than the generation before it. For a welding line, that means the tool lands where the program says it should, cycle after cycle.

The environment is the other difference. The wrist is rated IP67, and the manufacturer states the robot can operate reliably indoors and outdoors with high dust levels. Foundries, forging shops and heavy fabrication halls are rarely gentle on equipment, so this robustness belongs to the core of the design rather than being an extra.

Which SR500A version fits which job?

The sources name two versions: the SR500A-360/2.83 and the SR500A-500/2.52. The figures on this page belong to the SR500A-360/2.83 alone and should not be read across to its sibling. The two designations point to different combinations of load and reach, so the choice between them depends on which constraint dominates in your cell. If the largest working envelope matters most, the SR500A-360/2.83 is the version this page describes. If your application is defined by a different load and reach balance, ask for the SR500A-500/2.52 figures when you request a quotation, and compare them side by side.

Who is the SR500A-360/2.83 for?

Automotive manufacturers and their suppliers are the clearest group. The manufacturer notes that the robot easily handles heavy loads such as welding tongs and can work with heavy components. Body-in-white lines, where heavy tongs must be positioned repeatedly, are a natural fit.

Foundries and forging operations are the second group. In forging, the robot is described as precisely manipulating large, bulky, heavy parts, which is work that is hard on people and hard on lighter machines. Casting plants benefit in a similar way.

Material handling operations form the third group: plants that move heavy units between stations, pallets or machines, and that need long reach to cover the distance. System integrators who build cells for these industries will also find the wide range of motion useful when they design layouts with limited floor space.

Buyers whose parts are light, and who need a smaller robot, will be better served elsewhere in the brand's range, such as the small payload models. Buyers who need a different heavy-duty balance should compare the SR500A-500/2.52.

What is the SR500A-360/2.83 used for?

1. Casting: handling heavy castings and the tooling around them in demanding foundry conditions.
2. Welding: carrying welding tongs and heavy welding equipment with repeatable positioning.
3. Material handling: moving large, heavy items across a wide working envelope.
4. Forging: manipulating large, bulky, heavy parts during forging processes.
5. Automotive production: working with heavy components and tools along vehicle manufacturing lines.
6. Dusty or outdoor installations: running reliably where dust levels are high, indoors or out, thanks to the protected wrist.

Repeatability is ±0.1mm. The manufacturer also states a 50% improvement in repeatability compared with the previous generation.

Can it work in dusty or outdoor conditions?

Yes. The wrist is protected to IP67, and the manufacturer states that the robot operates reliably both indoors and outdoors with high dust levels.

Which controller does it use?

The controller model is SRC L5, and the power capacity is 15 KVA. Whether the controller is included in the delivery is confirmed at quotation.

Is there a version with a different payload and reach?

Yes, the SR500A-500/2.52 is named as a sibling version. Its figures are not given here, so ask for them when you request a quotation.

Where can I buy the SR500A-360/2.83 and what does it cost?
