SIASUN Industrial Robot Arm (SR80B)

Eighty kilograms on the flange and a tenth of a millimetre at the tool tip: those two figures pull in opposite directions, and much of the engineering in a heavy-duty arm goes into holding them together. The SIASUN Industrial Robot Arm (SR80B) is a 6-axis robot arm with an 80 kg payload, a reach of 1379.5 mm and a repeatability of 0.1 mm, on a structure weighing 500 kg. That combination places it where heavy grippers, process heads or substantial workpieces must be handled precisely within a relatively compact working envelope, rather than swung across a long production line.

Robots Europa, based in Dublin, supplies the SR80B to manufacturers, system integrators and research organisations throughout the European Union and the DACH region. Robots Europa prepares each quotation around the buyer's application and coordinates delivery and after-sales support from the first enquiry to commissioning.

Background

SIASUN and its industrial robot range

The SR80B is manufactured by SIASUN, which offers it as part of a wider family of industrial arms that includes the SR20A, SR25A, SR50A and SR210A models as well as SP-series arms. For buyers, the practical value of a family like this is continuity: once an engineering team has learnt one SIASUN arm, comparing neighbouring models becomes a question of payload, reach and cell layout rather than a fresh evaluation of an unfamiliar supplier. The full selection is gathered in our Robot Arms category.

Positioning: heavy payload in a compact envelope

Articulated six-axis arms are the workhorses of factory automation because their joints allow an end effector to be positioned and oriented freely, reaching around fixtures and approaching parts from awkward angles. Within that class, the SR80B pairs a payload of 80 kg with a reach of 1379.5 mm. The payload leaves room for heavy end-of-arm tooling, tool changers or dense parts; the reach keeps the arm suited to a tightly planned cell rather than a sprawling one. Its repeatability of 0.1 mm means a programmed point is returned to consistently, which is what assembly, dispensing and layered deposition depend upon.

Technical Specifications

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

The manufacturer has not published the dimensions, power supply, IP rating, controller, axis speeds, axis ranges, mounting options, operating temperature, communication interfaces or included accessories; Robots Europa confirms each of these at quotation.

What does an 80 kg payload with 1379.5 mm reach mean for a work cell?

Payload on a robot data sheet is the whole load carried at the flange, so it has to cover the gripper, any tool changer, hoses and sensors as well as the part itself. An 80 kg rating is generous in that respect: it allows a robust mechanical or vacuum gripper to be fitted and still leaves capacity for a substantial workpiece, or it allows a heavy process head to be carried for dispensing or deposition work. In practice, the closer a load's centre of gravity sits to the flange, the more of that rating can be used, which an integrator assesses when sizing the tooling.

A reach of 1379.5 mm describes a working envelope suited to a compact cell. The arm can serve fixtures, conveyors and tables arranged around its base without the floor space that longer-reach machines demand. For many factories that is an advantage rather than a limitation: a smaller footprint is easier to guard, easier to fit into an existing hall and simpler to replicate across several lines.

The 500 kg weight of the arm also matters at the planning stage. It informs the foundation or base plate, the anchoring method and the logistics of moving the unit into position, all of which are agreed with Robots Europa during project planning.

What should be confirmed before integrating the SR80B?

A robot arm is only one part of a production cell. Before an order is placed, the controller, the communication interfaces to the existing PLC or line control, the power supply and the environmental rating all need to be matched to the site. Robots Europa resolves these points with the manufacturer as part of the project, so that the buyer receives a configuration that fits the cell rather than a generic one.

Safety and conformity sit alongside this. In the EU, the integrator of a complete robotic cell is responsible for its risk assessment and CE marking under the machinery rules, covering guarding, safety-rated controls and the end effector as well as the arm. Planning that work early keeps commissioning on schedule and avoids redesigning guarding once the arm is on site.

Who is the SIASUN Industrial Robot Arm (SR80B) for?

The SR80B suits manufacturers who need a single arm to carry heavy tooling or parts with consistent positioning, in a cell that cannot spread across the floor. Typical buyers include production engineers automating assembly or material handling stations, system integrators building turnkey cells for their own customers, and companies developing additive manufacturing or dispensing processes that call for a stable, repeatable path. Universities and applied research institutes evaluating heavy-payload automation form a further group. Further machines for production environments are listed under Factory Robots.

Where the task sits outside the SR80B's payload or reach, a neighbouring SIASUN model may be the better fit, and Robots Europa can set the options side by side at quotation. Buyers handling lighter parts may compare the SIASUN Industrial Robot Arm (SR50A-50/2.15), those with heavier loads the SIASUN Industrial Robot Arm (SR210A-210/3.05-DW), and those focused on stacking at the end of the line the SIASUN Industrial Palletizing Robot Arm (SP120A-120/2.50).

What is the SIASUN Industrial Robot Arm (SR80B) used for?

1. Additive Manufacturing — guiding a deposition or printing head along layered paths where repeatable positioning governs the quality of each layer.
2. Assembly — placing and joining heavy components that would strain operators or slow a manual station.
3. Dispensing — applying adhesives, sealants or other media along a consistent bead path on parts or assemblies.
4. Material Handling — transferring substantial parts between conveyors, fixtures and machines within a compact cell.
5. Remote TCP — moving the workpiece past a stationary tool, such as a fixed nozzle or spindle, with the tool centre point held in space.
6. Process development — trialling new automated processes in pilot cells before they are rolled out to series production.
