SIASUN Industrial Robot Arm (SR25-20/1.76)

Most robot arms are bolted to a floor and look up at their work. The SIASUN Industrial Robot Arm (SR25-20/1.76) is one that can also hang from above, reaching down into a cell and leaving the floor free for conveyors, pallets and people. It is a 6-axis arm built for repeatable, high-throughput operations, with a 20 KG payload and a maximum working radius of 1,760 mm.

The product is available through this page, by quotation.

Background

The company behind the arm

The SR25-20/1.76 is made by Siasun Robot & Automation Co., Ltd. The arm is a high-performance industrial robot designed for heavy-duty tasks with exceptional precision and flexibility. That sentence sets the tone for the whole machine: it is meant for production work, not for demonstration or light hobby use.

Siasun is known for industrial robots, and its wider range also includes mobile robots and other automation equipment. If you are comparing several machines from the same maker, the SIASUN category gathers them in one place. Staying with one manufacturer across arms and mobile platforms can simplify training, spare parts planning and conversations with the supplier later on.

Where this arm sits in the line

The model name carries its own summary: the figure 20 matches the 20 KG payload and the figure 1.76 matches the 1,760 mm maximum working radius. That makes it a mid-sized, long-reach manipulator. It is not a bench-top arm for light pick-and-place, and it is not a giant for moving whole vehicle bodies. It sits where many general factories actually work: moving, joining and stacking parts that are heavy enough to need a proper industrial arm, in cells where reach matters as much as strength.

The arm is paired with the SRC M5 controller, an innovative controller that provides reliable, accurate and easy-to-use control. Together, the arm and controller form the working package that integrators and plant engineers evaluate, program and maintain.

What makes the SR25-20/1.76 suited to heavy-duty work?

Three figures work together here. The payload of 20 KG is the capacity for demanding tasks such as material handling, palletizing and welding. The maximum working radius of 1,760 mm gives the arm coverage over a large area from a single mounting point. The repeatability of ±0.05 mm means the arm can return to a taught position with consistent accuracy, which matters for intricate, high-precision tasks.

Buyers often have to trade one of these against the others. A long reach and a heavy payload usually make an arm harder to keep accurate. The SR25-20/1.76 is a machine that keeps all three together, so a single cell can combine a heavy tool, a wide work envelope and steady positioning. For a plant that would otherwise need two different robots for two different jobs, that is the practical appeal.

The power capacity of 3 KVA offers a balance between performance and energy consumption. For a facility planner, it is a useful number to put next to the electrical supply available at the cell, and the wider electrical questions can be raised when the quotation is prepared.

Why do upright and inverted installation matter?

The arm can be installed in both upright and inverted positions. This is more than a footnote. An upright arm on the floor is the familiar choice and works well when the cell has room around the base. An inverted arm, hung from a frame or gantry, can free the floor and let the arm approach a workpiece from above. In crowded production areas, that can decide whether a robot fits at all.

This flexibility allows seamless integration into diverse manufacturing environments. For a buyer in a region with mixed-use plants, such as a bottling line, a fabrication shop or a distribution warehouse, the choice of mounting often follows the building rather than the robot. Having both options on one model lets the integrator adapt the layout instead of rebuilding the space around the machine.

Base dimensions and fixing details should be requested before any cell drawing is finalized.

Who is the SIASUN Industrial Robot Arm (SR25-20/1.76) for?

The first group is manufacturers who weld. A 6-axis arm with this reach can carry a welding tool along long seams or around larger fabrications, and the stated repeatability supports consistent results from one part to the next.

The second group is operators of material handling and palletizing lines. Food and beverage packers, building-material suppliers and distribution centers all stack, move and sort cartons, bags and components. A 20 KG payload and a reach of 1,760 mm make a sensible match for many of these cycles.

The third group is assembly and machine-building teams. Assembly work depends on position accuracy, and the ±0.05 mm repeatability is the figure those teams will want to examine against their tolerances.

The fourth group is system integrators. They value a controller they can set up and a mounting choice that adapts to the customer's building. If you are also considering mobile platforms to feed such a cell, you can look at the SIASUN 20T Heavy-Duty Mobile Robot as part of a wider project. This arm is not aimed at buyers who need very light payloads or a small bench-top machine.

What is the SIASUN Industrial Robot Arm (SR25-20/1.76) used for?

1. Welding. The arm carries a welding tool through the work area with repeatable motion from part to part.
2. Material handling. It lifts and moves parts between stations, conveyors and machines within a 1,760 mm radius.
3. Palletizing. It stacks cartons, bags or components onto pallets with a payload of 20 KG.
4. Assembly. It positions components with a repeatability of ±0.05 mm for consistent fit.
5. Overhead cell layouts. Inverted installation lets it work from above and keeps the floor clear.
6. Floor-mounted production cells. Upright installation suits standard cells where the base stands beside the work.
