SIASUN Industrial Robot Arm (SR50A-50/2.15)

In a machine tending cell, a robot is rarely defeated by the weight of the part it lifts. The trouble more often starts at the wrist, where the robot's own wiring meets the air lines and sensor leads an integrator adds, and one snag on a fixture stops a shift. The SIASUN Industrial Robot Arm (SR50A-50/2.15) addresses that weak point directly. Its J6 motor is fully enclosed and its wiring runs as integrated spiral cables, so the arm's cabling keeps clear of whatever tooling the user installs. Behind that orderly wrist sits a six-axis arm rated for 50kg and reaching 2158mm, built for the medium-load work of automotive, electronics and precision manufacturing plants.

Robots Europa, based in Dublin, sells the SR50A-50/2.15 and supplies it to customers throughout the European Union and the DACH region. Robots Europa prepares each quotation, arranges delivery to the installation site and remains the point of contact for support once the arm is commissioned.

Background

SIASUN and its articulated arm family

SIASUN is a Chinese automation manufacturer whose range extends from articulated industrial arms to mobile robots and service machines. Its industrial arms are grouped into series, and each model code pairs the series designation with ratings for that particular version. For this arm, the figures in the code correspond to the payload of 50kg and a working radius of 2.15 metres. The sources for this product also name two further versions, the SR50A-70/2.15 and the SR25A-35/1.80. They are separate machines with their own ratings, and no figure for the SR50A-50/2.15 should be read across to them, or the other way round.

Positioning: a medium-load arm with a clean wrist

The SR50A-50/2.15 is a six-axis robot designed specifically for medium-load applications. Medium-load arms fill the space between compact units that handle small components and heavy machines built for engine blocks or full pallets. They carry substantial grippers and workpieces while remaining compact enough for crowded production halls. SIASUN equips this arm with advanced servo drive technology and a high-precision control system, which maintain stability and accuracy at high speed. A flexible joint structure, combined with intelligent software support and an intuitive programming interface, makes programming straightforward and shortens the path from installation to productive use in assembly, material handling and precision machining.

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 axis speeds, the axis working ranges, the rated power supply, the controller specifications, the operating temperature, the wrist moment ratings or the contents of the delivery; these are confirmed at quotation.

Why is the SR50A-50/2.15 well suited to machine tending?

Machine tool loading and unloading, together with multi-station material handling, are the applications this arm suits particularly well. Each figure supports that case. A reach of 2158mm gives a single robot base a generous working envelope, so a cell can be laid out with a machine tool, an infeed conveyor and an outfeed station grouped around one arm instead of each needing its own handling device. The 50kg payload rating has to cover the gripper and the workpiece together. Integrators therefore calculate the combined mass of tooling and part against that figure when designing the end effector.

Precision matters as much as strength when parts go into chucks, vices and fixtures. A repeatability of ±0.05mm means the arm returns to a taught position consistently, cycle after cycle, which is what reliable seating of a part in a machine depends on. The IP65 rating applies to the wrist, the part of the arm that works closest to the machining zone. Under the IEC 60529 scheme, IP65 denotes protection against dust ingress and against water jets, a relevant level near machine tools where coolant and fine swarf are present. The enclosed J6 motor and the integrated spiral cables complete the picture: the arm's own wiring stays clear of the hoses and signal lines added for grippers and part sensors, which reduces the risk of cables wearing or catching as the wrist rotates between stations.

What should integrators confirm before specifying the SR50A-50/2.15?

The specification table covers the figures most buyers compare first: payload, reach, repeatability and wrist protection. Cell design needs more than that. Floor loading and the choice of mounting plate depend on the arm's weight. Cycle-time estimates depend on the axis speeds, and the layout of guarding and fixtures depends on the working range of each axis. Electrical planning needs the rated power supply, and the operating temperature determines whether the arm can be placed close to heat-generating processes. Robots Europa supplies these details before a layout is fixed.

For installations in the European Union, the integrator who assembles the complete cell is responsible for its conformity assessment and CE marking under European machinery legislation, including risk assessment, guarding and safety functions. Robots Europa advises on the documentation and scope of supply that accompany the robot itself.

Who is the SIASUN Industrial Robot Arm (SR50A-50/2.15) for?

The first group is production engineers in automotive supply chains who need to load and unload machining centres or move components between stations without investing in a heavy-payload arm. The second is electronics and precision manufacturers, the industries the arm is designed for, for whom repeatable placement and orderly cabling count for as much as lifting capacity. The third is system integrators building machine tending and material handling cells for clients across the EU and the DACH region, who value an IP65 wrist rating and wiring that will not interfere with their own dress packs. Contract machining shops looking to keep spindles running across extra shifts also fall within its natural audience.

The sources name the SR50A-70/2.15 and the SR25A-35/1.80 as further versions; they are distinct machines with their own ratings. Where a project calls for a different load or reach, Robots Europa also lists other SIASUN arms, among them the SIASUN SR25A-25/1.80, the SIASUN SR25A-12/2.01, the SIASUN SR210A-210/3.05-DW and the SIASUN SR500A-360/2.83. Their ratings should be taken from their own pages.

What is the SIASUN Industrial Robot Arm (SR50A-50/2.15) used for?

1. Machine tool loading and unloading: feeding blanks into machining centres and lathes and removing finished parts, the application this arm is particularly suited to.
2. Multi-station material handling: moving workpieces between conveyors, fixtures and inspection points from a single base position.
3. Assembly: positioning and joining components where consistent placement is required throughout a shift.
4. Precision machining support: presenting parts to processes in which repeatable positioning directly affects quality.
5. Automotive component production: handling medium-weight parts in supplier plants and body or powertrain sub-assembly cells.
