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

Most heavy-payload robots ask you to accept a trade: strength in exchange for sluggish, vibration-prone motion. The SIASUN SR360A-360/2.83 (SR360A-360/2.83) is built to argue against that bargain, pairing a 360 kg (793.7 lbs) payload with a backlash-free J5 gearbox, self-developed high-torque motors and a body without a counterweight.

Background

SIASUN and its engineering lineage

SIASUN is an industrial robot manufacturer with more than two decades of engineering validation and thousands of project experiences behind it. The company pairs robot products with the applications they serve, rather than selling an arm in isolation. For a buyer in the Caribbean, where a plant may have only one or two robot cells and little room for trial and error, that application-first thinking matters: the robot is expected to arrive ready to work in a defined role.

The SR360A series sits in the heavy end of the SIASUN range. Within the family, the same designation comes in more than one version. The SR360A-360/2.83 described here carries a 360 kg (793.7 lbs) payload, while the sibling SR360A-280/3.20 is listed with a 280 kg (617.3 lbs) payload. Each figure on this page belongs to the version it is stated for.

Positioning and key technology

The SR360A-360/2.83 is positioned as a robot that combines high rigidity, high speed, easy maintenance and easy deployment. Each of those qualities rests on a specific design choice.

Rigidity comes from the J5 axis, which adopts a backlash-free gearbox. This enhances overall rigidity and reduces start-stop vibration. Speed comes from self-developed high-torque motors, which increase spot welding rhythm by over 10%. Maintenance is eased by a no-counterweight robot body, a design that lowers the failure rate. Deployment is supported by a control cabinet that handles mainstream protocols and reserves expansion space.

If you are comparing the wider range, the Large Payload category gathers the heavy-duty models, and the Industrial Robots category shows the full SIASUN line.

What makes the SR360A-360/2.83 different from a conventional heavy-payload robot?

The difference lies less in one headline number than in how the arm is put together. Many heavy robots rely on a counterweight to balance the load on the arm. The SR360A-360/2.83 uses a no-counterweight design, which reduces high-frequency moving parts and so lowers the probability of failure. For a plant that must keep a cell running with limited spare parts on the island, fewer moving parts is a practical benefit.

The second difference is the J5 gearbox. A backlash-free design removes the small amount of play that otherwise shows up when an axis starts and stops. The result is higher overall rigidity and less start-stop vibration, which is exactly what a heavy tool or workpiece makes difficult.

The third is the motors. They are self-developed by SIASUN and high in torque, and they increase spot welding rhythm by over 10%. Together with a repeatability of ±0.01mm and an IP67 wrist, the robot is aimed at demanding, repetitive production work.

How does it differ from the SR360A-280/3.20?

The two versions share a series name but not a payload. The SR360A-360/2.83 lifts 360 kg (793.7 lbs) and has a reach of 2830mm, while the SR360A-280/3.20 is listed at 280 kg (617.3 lbs). Other figures of the SR360A-280/3.20 are not part of this page. If your loads sit close to the upper limit, the 360 kg version is the one to specify.

Who is the SR360A-360/2.83 for?

This robot suits manufacturers that handle heavy parts and cannot afford a wobbling arm. Typical buyers include:

• Automotive and metal fabrication plants that need spot welding or heavy part handling with a steady rhythm.
• System integrators building production lines, who benefit from a control cabinet that supports mainstream protocols and reserves expansion space.
• Plants with external axes, since the cabinet reserves space for external axis driver installation.
• Maintenance-conscious operators who value a body with fewer moving parts.

Buyers whose loads are lighter may look at the mid-range models such as the SIASUN SR270A-270/2.70, the SIASUN SR220A-220/2.66 or the SIASUN SR210A-210/2.65. Their figures are listed on their own pages.

What is the SR360A-360/2.83 used for?

1. Handling: moving heavy parts and assemblies between stations with a 360 kg (793.7 lbs) payload.
2. Assembly: placing large components where rigidity and repeatability of ±0.01mm matter.
3. Gluing: applying adhesive along a path with reduced start-stop vibration.
4. Loading and unloading: feeding machines and taking finished workpieces away.
5. Spot welding: working with high-torque motors that raise the welding rhythm by over 10%.
6. Line integration: joining a production line through the control cabinet and its reserved expansion space.

Frequently Asked Questions

What payload and reach does the SR360A-360/2.83 have?

The payload is 360 kg (793.7 lbs) and the reach is 2830mm. Both figures belong to this version only.

How precise is the robot?

The repeatability is ±0.01mm for this version.

Is the wrist protected against dust and water?

Yes, the wrist protection is IP67.

Why does the robot have no counterweight?

The no-counterweight body reduces high-frequency moving parts, which lowers the failure rate.

Can it be integrated into an existing production line?

The control cabinet supports mainstream protocols and reserves expansion space, including space for external axis driver installation.

Which applications is it designed for?

It is designed for handling, assembly, gluing, loading and unloading, and spot welding.

Where can I buy the SR360A-360/2.83 and what does it cost?

You can buy it through this page by requesting a quotation. We do not publish prices; the cost depends on your configuration and is given with the quotation.

Summary

The SIASUN SR360A-360/2.83 answers the old question of whether a strong robot must be a clumsy one. A 360 kg (793.7 lbs) payload, a 2830mm reach, ±0.01mm repeatability and an IP67 wrist are backed by a backlash-free J5 gearbox, high-torque motors and a body without a counterweight. For heavy handling, assembly, gluing, loading and unloading, and spot welding, it is a serious candidate. To compare versions or settle the details left open above, this page is the starting point.
