SIASUN Industrial Robot Arm (SR20A)

Most factory cells are built around a compromise: an arm strong enough for the heaviest tool, yet nimble enough to reach into a fixture without crowding the cell. The SIASUN Industrial Robot Arm (SR20A) is a robot built for that middle ground. It carries a 20 kg payload across a 1745 mm reach, and it returns to a taught point with 0.1 mm repeatability, which is the combination that decides whether a cell runs smoothly or constantly needs adjustment.

The product is available through this page, by quotation.

Background

The manufacturer behind the SR20A

The SR20A is manufactured by Siasun, a robotics maker whose industrial arms carry the SIASUN brand. Within that range the model designations tell a buyer where a robot sits. The SR20A is a 6-axis articulated arm, the layout most integrators reach for first, because six axes let the tool approach a workpiece from almost any direction.

For buyers in the Caribbean, the brand matters less than the question of what the robot will do in a real plant: a bottling line, a fabrication shop, a packaging hall or a repair workshop. Industrial arms of this kind are chosen for the work they repeat all day, and the SR20A is tied to a short list of applications that we cover below.

Where the SR20A sits in the range

The SR20A is one model among several SR-series arms, so a buyer can compare options within the same family. If a project needs a different working envelope, the SR25A and the SR50A are worth reviewing alongside it, and heavier work belongs to the SR210A. Each is linked in the buyer section below.

The SR20A itself is positioned by its figures: a 20 kg payload for tooling and workpieces of moderate weight, and a reach of 1745 mm that covers a generous work area from a single base. It is one of the Robot Arms that suit general factory duty, and it belongs to the wider family of Factory Robots.

Technical Specifications

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

The manufacturer has not published the protection rating, the power supply, the controller model, the joint speeds, the axis motion ranges, the mounting options, the communication interfaces, the contents of the box or the operating temperature; they are confirmed at quotation.

What does the SR20A offer for a cell with a mix of tasks?

The strength of the SR20A is breadth. Its common applications are additive manufacturing, assembly, dispensing, material handling, remote TCP and welding. These jobs ask different things of a robot. Welding wants a steady path. Dispensing wants a consistent speed along a bead. Assembly wants a repeatable return to the same point. Handling wants enough payload for the gripper plus the part. A 6-axis arm with a 20 kg payload and 0.1 mm repeatability is a sensible answer to that spread, and a plant that expects its product mix to change can redeploy the same arm rather than buy a new machine for each job.

Reach is the other half of the story. At 1745 mm, the arm covers a large area around its base, so one robot can serve a machine, a pallet position and a conveyor without being moved. That is useful in plants where floor space is limited, as it often is in smaller Caribbean facilities.

How should the payload and weight be read together?

The 20 kg payload is the load the arm is specified to carry, and a buyer should count the gripper, the cables and the tool as well as the workpiece when sizing it. The arm itself weighs 500 kg, which matters for the floor, the base plate and the way it is lifted into position during installation. Plan the foundation and the lifting equipment before delivery, not after.

Who is the SR20A for?

The first group is the manufacturer or workshop that wants a first industrial robot for welding or assembly. A single 6-axis arm with a defined payload and repeatability is easier to justify and to program than a bespoke machine, and the six listed applications give room to grow.

The second group is the integrator. Builders of turnkey cells in the region need an arm whose basic figures are clear: payload, reach, repeatability and weight. The SR20A gives those figures.

The third group is the plant already running material handling by hand, such as moving parts between stations. For heavier loads, the SIASUN Industrial Robot Arm (SR50A-50/2.15) or the SIASUN Industrial Robot Arm (SR210A-210/3.05-DW) deserve a look. For a project where the tool and part are a little heavier than the SR20A is meant for, the SIASUN Industrial Robot Arm (SR25A-25/1.80) is the closest neighbor to consider.

The SR20A is less suited to buyers who need a particular protection rating for a washdown area. Raise that when you request your quotation.

What is the SR20A used for?

1. Welding. Carries a torch along a programmed seam and returns to the same point on every part.
2. Assembly. Places and fits components at stations where repeatable positioning matters.
3. Dispensing. Moves a nozzle along a path to lay adhesive, sealant or other material.
4. Material handling. Moves parts between conveyors, machines, fixtures and pallets.
5. Additive manufacturing. Positions a print head or deposition tool through a six-axis path.
6. Remote TCP. Holds the workpiece and moves it around a fixed tool, a method used for tasks such as finishing or dispensing.

Pricing and Availability

We do not print prices on this page. Every project differs in tooling, installation and support, so quotation is the way to proceed: send us your application and we will respond. Delivery, customs and support are arranged with the quotation. The SIASUN Industrial Robot Arm (SR20A) is available on this page.

Frequently Asked Questions

How many axes does the SR20A have?

The SR20A is a 6-axis robot arm, which lets the tool approach a workpiece from many directions.

What payload and reach does it have?

The payload is 20 kg and the reach is 1745 mm.

How accurate is the SR20A?

Its repeatability is 0.1 mm, meaning it returns to a taught position with that consistency.

How heavy is the robot?

The arm weighs 500 kg, so the floor, base and lifting equipment should be planned ahead.

Which applications is it used for?

Additive manufacturing, assembly, dispensing, material handling, remote TCP and welding.

Is the protection rating or controller model given?

Neither appears in the specification table above. Tell us what your project needs when you request your quotation.

Where can I buy the SR20A and what does it cost?

You can request it through this page. We do not print prices; the cost is given in a quotation that also covers delivery, customs and support.

Summary

The SR20A earns its place by being neither extreme nor narrow. A 20 kg payload, a 1745 mm reach and 0.1 mm repeatability on a 6-axis arm cover the middle of factory work, from welding and assembly to dispensing and handling. The 500 kg weight is a planning point for the floor and the lift. For a robot that can serve several tasks in one cell, this page is the starting point.
