SIASUN Industrial Robot Arm (SR25A-25/1.80)

SIASUN Industrial Robot Arm (SR25A-25/1.80)

Positioned in the widely used ~25 kg payload class, the SR25A-25/1.80 emphasizes reach and deployment flexibility for production cells that need a balance of working envelope, repeatability, and end-effector versatility. According to manufacturer-published specifications, the model is rated for 25 kg maximum payload with an approximately 1.8 m (1803 mm) maximum reach, making it suitable for operations spanning conveyors, fixtures, and multi-station work areas.

Industrial robots in this category are typically integrated as part of a broader automation system that includes a controller, safety hardware, tooling (grippers, weld guns, dispensers), sensors (vision, force/torque, proximity), and application software. In many deployments, the robot arm’s role is to deliver consistent motion and repeatable tool positioning, while system-level design determines throughput, safety performance, and product quality.

Design and Features

Mechanical architecture

The SR25A-25/1.80 uses a conventional articulated (serial) 6-DOF manipulator layout: multiple rotary joints allow the robot to position and orient a tool within a 3D workspace. This arrangement supports common industrial motion patterns such as approach–engage–retract cycles, wrist reorientation, and obstacle-avoiding paths.

Installation flexibility

The robot is specified to support floor mounting and inverted installation, which can be useful in crowded production cells where overhead mounting frees floor space for conveyors, fixtures, and operator access.

Environmental protection for industrial cells

Manufacturer information indicates an IP65-rated wrist (environmental protection at the wrist area), a feature often valued in facilities where the wrist is exposed to dust, coolant splash, or process residue.

Technology and Specifications

Core specifications (manufacturer-published)

Key published specifications for the SR25A-25/1.80 include:

• Degrees of freedom: 6 axes

• Maximum payload: 25 kg

• Maximum reach: 1803 mm

• Repeatability: ±0.05 mm

• Wrist protection: IP65

Independent product listings commonly echo the same top-line parameters (payload, reach, and repeatability), suggesting broad consistency in how the model is represented across industrial catalogs.

Control and integration considerations

While exact controller variants and software options can differ by region and configuration, industrial robot arms in this class generally support:

• Digital/analog I/O for grippers, sensors, and tooling

• Fieldbus/Ethernet-based connectivity for PLC integration

• Path programming via teach pendant plus offline programming in some workflows

• Safety integration with interlocks, light curtains, scanners, and safety PLCs

System integrators typically validate performance based on the application’s duty cycle, tool mass/inertia, acceleration needs, and accuracy requirements. For example, payload rating is not only about mass, but also about how far the tool’s center of gravity is from the wrist and how aggressively the robot must accelerate.

Safety standards context

Industrial robot deployments commonly reference international safety frameworks such as ISO 10218-1/10218-2 (robot and robot system safety requirements), which shape safeguarding design, risk assessment, and integration practices.

Applications and Use Cases

Material handling and palletizing-adjacent tasks

A ~1.8 m reach can be advantageous for pick-and-place across conveyors, kitting operations, and material transfer between stations. The SR25A-25/1.80’s payload class is often used when handling moderate-weight parts, multi-part trays, or grippers with additional sensors.

Machine tending

Machine tending is a common use case for 6-axis arms: loading/unloading CNC machines, presses, or inspection fixtures. Reach helps the robot service multiple machines or access deep work areas, while repeatability supports consistent positioning at chuck/fixture interfaces.

Assembly and fastening

In assembly lines, robots may apply fasteners, insert components, or hold parts for secondary processes. In these contexts, repeatability is typically more critical than absolute accuracy; calibration routines, fixtures, and compliance tooling often manage the remaining tolerance stack.

Dispensing and process tasks (variant-dependent)

Where environmental protection and tooling compatibility allow, industrial arms are used for dispensing, sealing, and adhesive application, especially in electronics, appliance manufacturing, and automotive supply chains. Process suitability depends on local safety rules, cell design, and tool qualification.

Advantages / Benefits

Balanced payload and reach for flexible cells

The combination of 25 kg payload and ~1.8 m reach is a practical middle ground for cells that need to span larger fixtures or multiple stations without moving the robot base.

Repeatability suited for production automation

A published ±0.05 mm repeatability aligns with many general manufacturing tasks where consistent tool return-to-position enables stable process outcomes.

Wrist protection for harsher zones

An IP65 wrist can reduce risk in environments where the robot’s distal joints face more exposure than the base (e.g., near spray, dust, or debris), though full-cell protection still depends on the enclosure and application.
