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

Picture a foundry bay where the air is thick with dust and the parts are too big for two people to move. The SIASUN Industrial Robot Arm with 2833mm Reach, 360kg Max Payload, 6 DOFs (SR500A-360/2.83) was built for exactly that kind of floor. It is listed in the Ultra-High Payload class and aimed at casting, welding and material handling, where most arms either run out of strength or lose their accuracy under the load.

Background

SIASUN and the SR series

SIASUN is a robotics manufacturer whose industrial arms are grouped in series by payload and reach. The model code of this arm follows that habit: SR500A is the series, 360 is the payload in kilograms and 2.83 is the reach in meters. Reading the code gives a buyer a quick first sense of where the arm sits among its siblings.

Within the family, the arm sits at the heavy end. Lighter models in the range, such as the SIASUN Industrial Robot Arm (SR50A-50/2.15), serve work where a smaller arm is enough. The SR500A-360/2.83 is for the jobs those arms cannot take on.

Positioning and key technology

This arm was developed specifically for heavy-load tasks. It has an all-new exterior design and a rigid arm structure, which enhance load capacity and broaden the range of applications. The rigid structure is paired with a high-performance transmission, and the result is fast overall cycle time and a 50% improvement in repeatability compared to the previous generation.

The wrist is protected to IP67, and the arm is well adapted to harsh production environments. It operates reliably both indoors and outdoors with high dust levels. That matters in casting and forging, where dust is part of the daily routine rather than an exception.

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

The first difference is purpose. Many industrial arms are designed around a medium payload and then stretched toward heavier work. This arm starts from the heavy load and builds the structure around it. A rigid arm structure and a high-performance transmission work together, and the outcome is quick cycle times with repeatability improved by 50% over the previous generation.

The second difference is the working envelope. A reach of 2833mm gives the cell designer room to place the arm, the fixtures and the workpiece without crowding them. For large castings and bulky parts, that distance often decides whether a cell layout works at all.

The third difference is endurance in rough surroundings. The wrist carries an IP67 rating, and the arm can work indoors and outdoors with high dust levels. A plant that cannot keep its floor spotless does not have to treat the robot as a delicate guest.

How does it compare with the other heavy-payload SIASUN arms?

The SR series includes several arms for heavy duty, and they differ in payload and reach. If your application calls for a different payload and reach, the SIASUN Industrial Robot Arm (SR210-120/3.05) and the SIASUN Industrial Robot Arm (SR210A-210/3.05-DW) are worth looking at. Each is quoted with its own figures, and none of their figures apply to the SR500A-360/2.83.

The arm described here is the one to consider when the 360 kg payload is the deciding requirement. If you are unsure, send us the weight of your heaviest workpiece together with the gripper or tool, and we will help you compare the options when preparing the quotation.

Who is the SR500A-360/2.83 for?

Foundries and forges are the clearest fit. During forging processes the arm precisely manipulates large, bulky, heavy parts, and that is a daily task in those plants.

Automotive suppliers and body shops form the second group. The arm easily handles heavy loads such as welding tongs, or works with heavy components, and both are common in vehicle production.

Fabrication shops and general material handling operations make up the third. If your cell moves large, heavy items several times an hour, an arm made for that job is easier to justify than a lighter one stretched to its limit.

Buyers whose parts are light should look elsewhere in the range. A smaller arm such as the SR50A-50/2.15 is a better match for lighter tasks, and it will usually suit the work more naturally.

What is the SR500A-360/2.83 used for?

1. Casting: Handling heavy castings and the related work around the casting cell, in dusty conditions the arm is rated to tolerate.
2. Welding: Carrying welding tongs and other heavy welding tooling that would overburden a smaller arm.
3. Material handling: Moving large, heavy parts between stations, with a reach of 2833mm to cover the work area.
4. Forging: Manipulating large, bulky, heavy parts precisely during forging processes.
5. Automotive manufacturing: Working with heavy components and heavy tooling on automotive lines.
6. Outdoor or dusty installations: Operating reliably indoors or outdoors where dust levels are high.

Frequently Asked Questions

What payload can the SR500A-360/2.83 carry?

The payload is 360 kg (793.7 lbs). Remember that grippers and tooling are part of the working load, so plan with the full weight in mind.

How far can it reach?

The reach is 2833mm. That gives a wide working envelope for large parts and for cell layouts that need space.

How accurate is it?

Repeatability is ±0.1mm, a 50% improvement compared to the previous generation.

Can it work outdoors or in dusty places?

Yes. It operates reliably both indoors and outdoors with high dust levels, and the wrist is protected to IP67.

Which controller does it use?

The controller model is SRC L5, and the power capacity is 15 KVA. Controller compatibility and the supply voltage are confirmed at quotation.

Are the weight and axis speeds available?

We confirm these figures, together with the other open specifications, when we prepare your quotation.

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

You can request it through this page, by quotation. We do not print prices; the cost depends on your project, and we will send an offer once we know your requirements.

Summary

The SR500A-360/2.83 is made for places where heavy parts, dust and the demand for accuracy all arrive at the same time. A 360 kg payload, a 2833mm reach, ±0.1mm repeatability and an IP67 wrist set it apart from lighter arms. It fits casting, welding, forging and material handling.
