SIASUN Industrial Robot Arm (SR50A-50/2.15)

Most robot cells are lost or won at the wrist, not at the shoulder. A strong arm that tangles its own cables around a fixture costs more shifts than a weak one ever will. The SIASUN Industrial Robot Arm (SR50A-50/2.15) is built around that lesson: a six-axis medium-load robot with a fully enclosed J6 motor and integrated spiral cables, made for cells where tooling, air lines and sensor leads all crowd the same few inches.

Background

SIASUN and its robot lineage

SIASUN is a Chinese automation brand that builds industrial robots for factory work. Its arms carry model names that pair a series code with a payload figure and a reach figure, so that a buyer can read the size of the machine from the name. The SR50A-50/2.15 follows that habit: the series is SR50A, the payload class is 50 and the reach class is 2.15.

The family also includes the SR50A-70/2.15 and the SR25A-35/1.80. On this page every figure belongs to the SR50A-50/2.15 alone, and none of them should be carried over to a sibling. The wider SIASUN range includes arms in other payload and reach classes, for example the SIASUN Industrial Robot Arm (SR25A-25/1.80) and the SIASUN Industrial Robot Arm (SR210A-210/3.05-DW).

Positioning and key technology

The SR50A-50/2.15 is a six-axis industrial robot designed for medium-load applications. Its working radius is generous for its class, and its lifting capacity sits at the level where a robot can handle real workpieces, grippers and fixtures rather than only light parts.

Two technical choices define the arm. The first is the drive and control package: advanced servo drive technology with a high-precision control system, which keeps the robot stable and accurate even at high speeds. The second is the wrist and cabling design. The J6 motor is fully enclosed, and spiral cables are integrated so that the robot's own cables do not interfere with cables the user installs. That detail is what makes the arm a natural fit for machine tool loading and unloading and for multi-station material handling.

Technical Specifications

The manufacturer has not published the weight, the axis speeds, the axis working ranges, the rated power supply, the controller specifications, the operating temperature, the contents of the box or the wrist moment ratings; they are confirmed at quotation.

What makes the SR50A-50/2.15 suited to machine tending?

Machine tending asks a robot to reach into a machine, place or remove a part, and withdraw without touching anything it should not. Three features of this arm address that job directly.

First, the enclosed J6 motor and integrated spiral cables. When a cell integrator adds a gripper, a sensor or an air line, the new cables must run alongside the robot's own. On this arm the two sets are kept apart by design, which reduces the chance of snagging during the repeated wrist rotations that loading and unloading require.

Second, the reach of 2158mm. A long working radius lets one robot serve a machine, a pallet or a conveyor position without being moved, and it supports multi-station layouts where a single arm feeds several points in turn.

Third, the wrist protection of IP65. Machine areas are rarely clean, and a wrist rated at this level is built for the dust and splash conditions that surround many production machines.

How accurate is the SR50A-50/2.15?

The repeatability is ±0.05mm. In practice that means the arm returns to a taught position with a very small spread from cycle to cycle, which matters in assembly, in precision machining support and in electronics work, where parts seat into fixtures with little room for error. The servo drive technology and the high-precision control system keep the arm stable and accurate at high speeds, so the figure is not meant to apply only to slow movements.

Who is the SR50A-50/2.15 for?

The arm suits manufacturers and integrators who need a medium-load robot with a long reach and a clean wrist. The main buyer segments are these.

Machine shops and metalworking plants that want to automate loading and unloading of machine tools and cannot afford cable interference at the wrist.

Automotive suppliers that move parts between stations, where payload and reach both matter.

Electronics and precision manufacturers that value the repeatability for intricate, exact tasks.

System integrators who build cells for several customers and want a standard six-axis arm with simple programming and software support.

If your task falls in a different payload or reach class, the SIASUN range offers other arms, such as the SIASUN Industrial Robot Arm (SR25A-12/2.01) or the SIASUN Industrial Robot Arm (SR500A-360/2.83). The SR50A-70/2.15 and the SR25A-35/1.80 belong to the same family; ask us how they compare for your application when you request a quotation.

What is the SR50A-50/2.15 used for?

1. Machine tool loading and unloading. The enclosed J6 motor and spiral cables keep the wrist clear while the arm serves the machine.
2. Multi-station material handling. The long reach lets one arm move parts between several positions.
3. Assembly. Accuracy and a flexible joint structure support intricate, exact assembly steps.
4. Precision machining tasks. The control system is built to hold accuracy at high speeds.
5. Automotive manufacturing. Medium-load handling and positioning in automotive production.
6. Electronics production. Careful, repeatable handling in electronics and other precision manufacturing.

Summary

The weak point of many robot cells is not the weight of the part but the tangle at the wrist. The SIASUN Industrial Robot Arm (SR50A-50/2.15) answers it with an enclosed J6 motor and integrated spiral cables, and backs that with a 50kg payload, a 2158mm reach, ±0.05mm repeatability and an IP65 wrist. It is a sound medium-load choice for machine tending, multi-station handling and precision work in automotive and electronics plants. To take the next step, this page is the starting point.
