SIASUN SR500A-500-2.52 (SR500A-500/2.52)

Some jobs are settled before the arm ever moves, by whether it is strong enough to hold the part at all. The SIASUN SR500A-500-2.52 (SR500A-500/2.52) is built for that kind of job: a heavy-duty robot with a large working envelope and a highly rigid structure, made for loads that leave lighter industrial arms behind.

The SIASUN SR500A-500-2.52 (SR500A-500/2.52) is available through this page, by quotation.

Background

SIASUN and its engineering lineage

SIASUN presents itself as a manufacturer with more than two decades of engineering validation and thousands of project experiences behind it. Its stated approach is to combine robot products with applications, so that a customer receives a working solution and not only an arm. That approach has earned the company the trust of customers around the world, and it is the thread that runs through the SR500A family.

For a buyer in the Caribbean, this history matters in a practical way. Heavy robots are rarely bought on a whim. They go into plants where the part, the fixture and the process are already known, and the supplier's project record is part of what is being purchased.

Where the SR500A-500/2.52 sits

The SR500A-500/2.52 is the 500 kg version of the SR500A line. The manufacturer describes it as combining a large working envelope with a highly rigid structure and powerful performance. High-performance core components and an optimized dynamic response give it high-speed cycle times, which is not what most people expect from a robot of this size.

The rigid structure is paired with a high-performance transmission. According to the manufacturer, this delivers fast overall cycle time and a 50% improvement in repeatability compared to the previous generation. A wide range of motion and a flexible joint structure allow greater working depth. This expands the workspace and improves production line flexibility and efficiency.

The design is highly modular and flexible, and it is applied in the automotive, lithium battery and general industrial sectors. The manufacturer calls it an ideal choice for heavy-load applications. If your loads are lighter, SIASUN also lists arms in its Small Payload category, and the heaviest classes sit in Ultra High Payload.

Technical Specifications

Specifications as published by the manufacturer; confirmed against the datasheet at quotation.

The manufacturer has not published the weight, the axis speeds, the axis motion ranges, the wrist moment and inertia, any mounting option other than upright, the operating temperature, the power supply voltage, the contents of the box or the controller compatibility; they are confirmed at quotation.

What makes the SR500A-500/2.52 different from a lighter heavy-duty robot?

The first difference is the load class. A 500 kg payload means the robot can take whole assemblies, large fixtures and heavy workpieces, where a lighter arm would need the part split up or handled with a gantry. The second is the way that capacity is delivered. The rigid structure and high-performance transmission are what allow the manufacturer to claim fast cycle times and a 50% improvement in repeatability over the previous generation, and the published repeatability is ±0.1mm.

The third is reach. At 2525mm, together with a wide range of motion and a flexible joint structure, the arm can work deeper into a cell than its size might suggest. That is useful when the part is bulky and the cell cannot be built around the robot without losing floor space.

If your application needs less payload but more reach, the SR500A-360/2.83 is the sibling to look at; you can read about it on the SR500A-360/2.83 page. We do not carry its figures over to this model, and each version is quoted on its own figures.

How does the IP67 wrist help in harsh environments?

The wrist comes standard with IP67 protection, which the manufacturer says enables reliable operation in harsh environments. The wrist is the part of an arm that works closest to the process, where dust, splashes and washdown are most likely to reach it. A protected wrist is one less thing to worry about in casting, handling and general heavy industry.

The protection rating given is for the wrist. The manufacturer has not given a rating for the rest of the arm in the material we hold, so we ask you to describe your environment when requesting a quotation and we will confirm what applies.

Who is the SR500A-500/2.52 for?

The first group is automotive plants and their suppliers, where heavy body parts, tooling and assemblies must be moved and positioned with consistency. The second is lithium battery manufacturers, who handle heavy modules and packs, and who value a robot that holds its position cycle after cycle. The third is general industry: foundries, metal fabricators and heavy equipment makers, where a part simply weighs too much for people or for lighter robots.

It also suits integrators who build cells for those customers and want a modular, flexible arm with a controller model already named, the SRC L5. Buyers who are still sizing their application should compare it with the SR500A-360/2.83, which is the other version named in the SR500A line. Buyers whose parts are far lighter will be better served by a smaller SIASUN arm than by this one.

What is the SR500A-500/2.52 used for?

1. Heavy part handling. Lifting and placing large, dense components that lighter robots cannot carry.
2. Automotive production. Moving heavy assemblies and tooling along lines where cycle time counts.
3. Lithium battery manufacturing. Handling heavy battery components with the repeatability the process demands.
4. General industrial work. Serving fabrication, casting and machine-tending cells in heavy industry.
5. Large fixture manipulation. Holding and turning bulky fixtures that carry the workpiece through a process.
6. Work in harsh conditions. Operating with an IP67-protected wrist where the environment is demanding.

Pricing and Availability

Delivery, customs and support are arranged with the quotation, so that you see the whole project and not only the arm. The SIASUN SR500A-500-2.52 (SR500A-500/2.52) is available on this page.

Frequently Asked Questions

What payload can the SR500A-500/2.52 carry?

The manufacturer states a payload of 500 kg (1102.3 lbs). This is the maximum payload for this version.

How far does it reach?

The reach is 2525mm. The wide range of motion and flexible joint structure allow greater working depth within that envelope.

How accurate is it?

The repeatability is ±0.1mm, and the manufacturer reports a 50% improvement over the previous generation. Some reseller listings show a different figure, so we confirm it against the datasheet at quotation.

Is the robot protected against dust and water?

The wrist comes standard with IP67 protection. The manufacturer has not given a rating for other parts of the arm in the material we hold.

Which controller does it use?

The controller model listed is the SRC L5, with a power capacity of 15 KVA. The installation method is upright installation.

Which industries use it?

The manufacturer names the automotive, lithium battery and general industrial sectors. Its modular and flexible design suits heavy-load applications in all three.

Where can I buy the SR500A-500/2.52 and what does it cost?

You can request it through this page, by quotation. We do not publish a price; the quotation covers the robot together with delivery, customs and support.

Summary

Strength alone does not make a heavy robot useful; it has to be rigid enough to stay precise and quick enough to keep a line moving. The SR500A-500/2.52 is SIASUN's answer to that tension, with a 500 kg payload, 2525mm of reach, ±0.1mm repeatability and an IP67 wrist, all stated by the manufacturer. For buyers in automotive, battery and general industry who need to move very heavy parts with consistency, this page is the starting point.
