SIASUN Collaborative Robot (GCR20-1400)

In practical deployments, a cobot such as the GCR20-1400 is often selected when an operation needs repeatable, programmable motion for handling, assembly assistance, machine tending, or inspection—especially in mixed environments where workers and automated equipment must operate in close proximity. The GCR20-1400’s naming convention aligns with a common industrial robot shorthand indicating ~20 kg payload and ~1400 mm working radius, matching its published technical parameters.

Design and Features

Collaborative form factor

The GCR20-1400 is built around a 6-axis articulated arm (6 degrees of freedom), enabling it to reach around fixtures, present a tool at multiple orientations, and follow curved paths for process tasks like dispensing or polishing.

Installation flexibility

The robot supports multiple mounting orientations—vertical, horizontal, and upside-down—which helps integrators place the cobot on mobile carts, overhead frames, machine enclosures, or compact cells where floor space is limited.

Environmental suitability

For typical indoor industrial environments, the robot is specified with an IP54 protection rating, supporting resistance to dust ingress and splashing water consistent with many factory-floor requirements (while not intended for washdown conditions).

Technology and Specifications

Core specifications

Published parameters for the GCR20-1400 include:

• Payload (rated load): 20 kg

• Degrees of freedom: 6

• Workspace radius (reach): 1400 mm

• Repeatability: ±0.05 mm

• Robot mass: 66 kg

These values place it among collaborative robot options intended for heavier handling, larger end-effectors, or multi-part picks compared with smaller 3–10 kg class cobots.

Joint motion ranges and speed

Joint ranges and maximum velocities are listed as:

• J1: ±360°, 120°/s

• J2: ±360°, 120°/s

• J3: ±160°, 180°/s

• J4: ±360°, 225°/s

• J5: ±360°, 225°/s

• J6: ±360°, 225°/s

In applied terms, these joint limits support full-wrist orientation control (continuous-style rotation ranges are common in collaborative arms) and allow reasonable throughput for pick-and-place, tending, and toolpath tasks, subject to payload and safety configuration.

Physical size, transport, and controller

The published dimensional and logistics-related figures include:

• Robot size: 1695 × 388 × 205 mm

• Transportation size (robot): 1060 × 500 × 600 mm

• Controller size: 410 × 306 × 292 mm

• Transportation size (controller/package): 480 × 395 × 376 mm

These figures help with practical planning for crating, shipping, and site commissioning.

Operating environment, lifetime, and noise

Operational and storage ranges are specified as:

• Ambient operating temperature: -10°C to +45°C

• Storage temperature: -40°C to +55°C

• Ingress protection: IP54

• Lifetime (listed): 35,000 hours

• Noise: ≤75 dB(A)

Applications and Use Cases

Manufacturing and assembly support

With a 20 kg rated payload, the GCR20-1400 is commonly suited to:

• Assisted assembly (presenting parts, holding components, applying controlled motion)

• Screwdriving or fastening with larger tool heads

• Material transfer between benches, conveyors, and fixtures

Machine tending

Cobots in this class are frequently deployed for CNC machine tending, press tending, and injection molding part handling, where reach and payload help cover door clearances, gripper weight, and part mass—while installation flexibility supports tight layouts.

End-of-line handling and packaging

The reach and payload are also aligned with:

• Case packing

• Kitting

• Pallet staging (light-duty / partial)
  Actual palletizing suitability depends on safety speeds, cycle-time targets, end-effector choice, and cell layout, but the reach class is compatible with many packaging footprints.

Inspection, measurement, and lab automation

Where a process needs stable, repeatable positioning—e.g., camera inspection, sensor scanning, or gauging—the listed ±0.05 mm repeatability can be relevant, especially for consistent presentation of parts to sensors.

Advantages / Benefits

Higher payload collaborative category

A 20 kg payload enables:

• Larger grippers and tooling

• Multi-part picks

• Handling heavier components without moving to a full industrial robot cell (depending on safety/risk assessment)

Broad workspace coverage

A 1400 mm reach can reduce the need for linear rails in some applications and allows coverage across wider worktables or multi-station fixtures.

Deployment flexibility

Support for vertical, horizontal, and inverted mounting simplifies integration into existing lines and can improve ergonomics by bringing the robot to the work rather than re-building the work around the robot.

FAQ Section 

What is the SIASUN GCR20-1400?

The SIASUN GCR20-1400 is a 6-axis collaborative robot arm with a 20 kg rated payload and a 1400 mm reach, designed for flexible automation in shared workspaces.

How does the GCR20-1400 work?

Like most cobots, the GCR20-1400 performs programmed motion across six joints to position a tool or gripper through a defined path. Its joint ranges and speed limits support multi-orientation handling and process tasks such as pick-and-place, tending, or toolpath operations.

Why is the GCR20-1400 important?

It fills a common automation gap: applications that need more payload and reach than small cobots while retaining collaborative deployment advantages such as flexible mounting and easier line integration. Its published repeatability of ±0.05 mm supports consistent task execution.

What are the benefits of the SIASUN GCR20-1400?

Key benefits include 20 kg payload capacity, 1400 mm workspace radius, 6-DOF motion, multiple mounting orientations (including upside-down), and an IP54 rating for typical indoor industrial environments.

Summary

The SIASUN Collaborative Robot GCR20-1400 is a 6-axis cobot platform defined by its 20 kg payload, 1400 mm reach, and ±0.05 mm repeatability, supporting flexible automation across assembly, machine tending, handling, and inspection workflows. With multiple mounting options and an IP54 rating, it is positioned for practical factory integration where payload and coverage requirements exceed those of smaller collaborative arms.
