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

Specifying a robot for half a tonne is less like buying a machine and more like committing to a piece of plant. The floor slab, the controller cabinet, the power feed and the guarding are all sized around the arm, and once the cell is commissioned that choice stays in place for years. The SIASUN SR500A-500/2.52 (SR500A-500/2.52) is built to justify that commitment. It pairs a maximum payload of 500 kg with a reach of 2525mm and a repeatability of ±0.1mm, so the engineering invested in a heavy-load cell is matched by an arm that can make full use of it.

Robots Middle East sells and supplies the SIASUN SR500A-500/2.52 to manufacturers and system integrators across the Middle East. Each unit is offered against the buyer's application, and Robots Middle East arranges delivery, customs clearance and after-sales support as part of that offer. Our team is pleased to review cell layouts, load cases and controller requirements with you before an order is placed.

Background

SIASUN and its engineering lineage

SIASUN is a Chinese robotics and automation company based in Shenyang. It grew out of the country's academic automation research and has since developed a broad portfolio of industrial, mobile and specialist robots. Its industrial arm range runs from compact machines in the Small Payload family to heavy-duty models in the Ultra High Payload category. The SR500A series belongs to the latter. It serves manufacturers whose parts, fixtures or assemblies are too heavy for mainstream arms but still need repeatable, programmable placement rather than simple lifting.

Rigidity and the new-generation transmission

The SR500A-500/2.52 rests on a large working envelope and a highly rigid structure. SIASUN pairs that structure with a high-performance transmission, and the combination delivers fast overall cycle times and a 50% improvement in repeatability compared to the previous generation. High-performance core components and optimised dynamic response give the arm its high-speed cycle times, even at heavy loads. The design is highly modular and flexible. That modularity is why SIASUN positions the robot for the automotive, lithium battery and general industrial sectors rather than for a single narrow task.

Technical Specifications

Specifications are as published by the manufacturer and are confirmed against the datasheet at quotation. The manufacturer has not published the weight, the power supply voltage, the axis speeds or motion ranges, the operating temperature, the wrist moment and inertia ratings, any mounting option other than upright, or what is supplied in the box; Robots Middle East confirms these details at quotation.

What makes the SR500A-500/2.52 different from the SR500A-360/2.83?

Both robots belong to the same SR500A family, but they are rated differently. The SR500A-500/2.52 carries a maximum payload of 500 kg (1102.3 lbs), while the SIASUN SR500A-360/2.83 is rated for 360 kg (793.7 lbs). Payload matters most when you choose a heavy-duty arm. The figure has to cover the part itself, the gripper or end effector, any vacuum or clamping hardware, and the dynamic effects of moving all of it quickly. A cell that handles heavy castings with a substantial gripper can exhaust a lower rating sooner than the part weight alone suggests.

For that reason, the SR500A-500/2.52 is the variant to consider when the combined load sits close to or above the sibling's rating, or when you want headroom for future, heavier products on the same line. Where the full tooled load stays comfortably within 360 kg, the sibling may be the more proportionate choice. The two model codes are not interchangeable, and each is specified on its own terms.

Why does IP67 wrist protection matter in a heavy-load cell?

The wrist is the part of an industrial robot that sits closest to the process. It meets coolant mist from machine tools, dust from grinding or fettling, and cleaning water during washdown. On the SR500A-500/2.52 the wrist comes with IP67 protection as standard, which enables reliable operation in harsh environments. Under the general IP classification, IP67 denotes an enclosure that is dust-tight and protected against temporary immersion.

For buyers in the Middle East this has practical weight. Fine airborne dust is a common feature of industrial sites in the region, and machine tending or foundry-adjacent cells add their own contaminants. Because the protection is standard rather than an option, you do not need to specify a separate upgrade package to put the arm into a dirtier process.

Who is the SIASUN SR500A-500/2.52 for?

The first group is automotive manufacturers and their tier suppliers. In these plants, body sections, subframes, axles and heavy tooling must move between stations quickly and land in the same place every cycle. The second group is lithium battery producers. As modules and packs grow larger, they call for an arm that can handle substantial, high-value loads with care. The third group is general industry: heavy fabrication, foundry finishing, machine building and logistics operations where manual handling of heavy items is slow or unsafe.

System integrators form a fourth audience. The modular and flexible design, the SRC L5 controller and the 15 KVA power capacity give a clear starting point for cell design and electrical planning. Buyers whose loads are well within 360 kg should also look at the SIASUN SR500A-360/2.83. Those handling light parts are better served by the Small Payload range, where a heavy-duty arm would be oversized.

What is the SIASUN SR500A-500/2.52 used for?

1. Automotive body and chassis handling – transferring heavy body sections, subframes and axle assemblies between stations on the line.
2. Battery module and pack handling – lifting and placing large lithium battery modules and packs during assembly and testing.
3. Heavy machine tending – loading and unloading large castings and forgings at machining centres, where the IP67 wrist faces coolant and swarf.
4. Heavy palletising and depalletising – stacking dense, heavy goods at the end of the line where manual handling is not practical.
5. Fixture and tooling exchange – moving heavy fixtures, dies or end-of-arm tools during changeovers to shorten downtime.
6. Large-component assembly – positioning heavy subassemblies repeatably for joining, fastening or inspection.
