FAIRINO FR5 vs. ESTUN S7-80 Eco: Price, Specifications and Application Fit

IN A NUTSHELL

A compact 7 kg tool-and-part budget versus the FR5 nominal 5 kg class: the S7-80 Eco adds 2 kg of rated capacity but has a shorter 800 mm workspace. The FR5 reaches 122 mm farther; a demanding fixture may favor either capacity or access. The FAIRINO FR5 is listed at $8,699; the documented ESTUN S7-80 Eco seller reference is approximately $8,880 USD. Compare the complete delivered cell before deciding.

This is a specification-based buying comparison. The models share a close nominal payload class, but equal payload does not guarantee equal reach, cycle performance or integration cost. Published specifications are separated from engineering judgments and the illustrative ROI scenario below.

The engineering choice

A compact 7 kg tool-and-part budget versus the FR5 nominal 5 kg class: the S7-80 Eco adds 2 kg of rated capacity but has a shorter 800 mm workspace. The FR5 reaches 122 mm farther; a demanding fixture may favor either capacity or access.

The 2 kg difference can be useful for a dual gripper, heavier fingers or a camera mounted near the flange. It does not remove the need to check inertia: a long gripper holding an offset workpiece can exceed a load chart even when total mass remains below the nominal rating.

The advertised lower price is only $181 above the FR5 price. Integration scope therefore matters more than a small headline difference. Compare equivalent tooling, controller, support and safety hardware before treating either as a cheaper installed solution.

ESTUN S7-80 Eco has 2 kg more headline rated capacity. That difference belongs to tooling as well as the part: a dual gripper, adapter, camera and cable allowance can consume it before the workpiece is added.

The FAIRINO FR5 reaches 122 mm farther on the published figures. The extra margin can help with a recessed fixture, but tool length, joint limits and approach angle still require simulation.

Side-by-side specifications

Speed figures use different definitions: a typical TCP value, an average motion figure and a maximum speed are not controlled cycle-time measurements. The table does not establish a throughput ranking. The quoted IP rating applies to the specified component and configuration, not automatically to the tool or complete cell.

Price comparison and what the numbers mean

FAIRINO FR5 is listed at $8,699 by FAIRINO USA. The numeric ESTUN S7-80 Eco reference is $8,880 USD, a hardware-reference gap of $181. On these references FAIRINO is approximately 2.0% lower in acquisition price. This is not a comparison of identically commissioned cells.

Xiangjing publishes a model-specific S7-80 Eco marketplace range of $8,880–$11,000 USD per set, minimum quantity one. The $8,880 value is the advertised lower endpoint used for the arithmetic, not a fixed configured quote. The listing title mentions an OnRobot gripper, so included robot, controller, pendant and tooling must be confirmed individually. Manufacturer specifications govern the engineering table; the seller copy contains a conflicting repeatability figure. This reference excludes any unconfirmed US taxes, freight, commissioning and support.

Price differences should be tested against the complete bill of materials: robot and controller, pendant, gripper, tool changer, camera and lighting, pedestal, guarding, machine interface, software licenses, freight, installation, training and support. A cheaper arm can require additional engineering; an expensive bundle can include functions the application does not need. Ask each supplier to identify included and optional items explicitly.

Payload, tooling and process margin

For an illustrative 2 kg component and 1 kg of gripper, adapter and cable allowance, the moving payload is 3 kg. This is inside both headline ratings, but it is only the first gate. A wide part held far from the flange can have more demanding inertia than a denser part of the same mass. Validate the actual tool, acceleration and orientation in both manufacturers' load models.

FAIRINO separately publishes a maximum of 7 kg for the FR5. This article uses its 5 kg nominal class to avoid equating a conditional maximum with another robot's standard rating. For the rival, use the exact ordered controller, arm revision and load chart. Neither purchase should be approved solely because the part's weight is below the number in the model name.

Reach, accuracy and cell layout

The FAIRINO FR5 reaches 122 mm farther on the published figures. The extra margin can help with a recessed fixture, but tool length, joint limits and approach angle still require simulation.

FAIRINO FR5 publishes the tighter repeatability figure. This may help taught-point handling, but it does not establish better absolute accuracy, loaded path tracking or finished-part quality.

Simulate the complete operation rather than only a straight reach from the base. Include an approach above the part, clearance around a door or chuck, tool reorientation, retreat paths and the position used for inspection. Longer reach can avoid an external axis, but can also increase the swept area and guarding requirement. Repeatability is only one part of the error budget: fixtures, calibration, deflection, temperature and camera setup influence the finished process.

Controller, programming and connectivity

FAIRINO publishes graphical programming and drag teaching through a teach pendant or web application, alongside developer interfaces for C#, C++, Python, ROS and ROS 2. Its controller documentation lists TCP/IP and Modbus TCP/RTU with optional industrial networks. Confirm the purchased controller, firmware and fieldbus licenses against the plant PLC and the selected tool.

ESTUN S7-80 Eco uses the Eco platform with graphical programming, hand guidance and configurable collision detection. Its 4 m/s maximum tool-end figure is not a speed that can automatically be used in every collaborative task. Confirm the controller and industrial-network options against the plant PLC.

A useful acceptance exercise is to have the future operator recover from a dropped part, a protective stop, a machine-not-ready signal and a power interruption. Count the steps required to restart safely and preserve traceability. This reveals operating cost that a specification sheet cannot show. Require program backups, documented I/O, spare-part identification and a named support route in the handover.

Power, environment and collaborative safety

ESTUN S7-80 Eco publishes approximately 250 W typical power for the referenced configuration. A controller's rated output or power-supply capacity is not its average energy consumption. Meter the intended duty cycle, including idle time and auxiliaries, before assigning an energy saving or annual operating-cost advantage.

The FAIRINO arm is specified at IP54 with an IP65 option. The rival specification used here is IP54 standard; IP67 option. Match coolant, dust, cleaning agents, connectors and controller placement to the exact ordered configuration. A higher arm IP rating does not establish food-contact suitability or permit unrestricted washdown of the entire installation.

Collaborative capability is a property of the complete task as well as the robot. Evaluate tool sharpness, hot work, dropped loads, crushing points, contact forces and stopping distance. Machine access can require interlocks or guarding even when the robot supports collaborative functions. Validate the final settings under the applicable standards and the installed firmware; do not translate a product certification into an unconditional fence-free claim.

Illustrative ROI: use complete cell cost

Assume, solely for a transparent illustration, identical additional integration cost of $15,000 and net recurring savings of $1,000 per month. The FAIRINO cell would total $23,699, giving simple payback of 23.7 months. The rival-reference cell would total $23,880, giving 23.9 months. These are arithmetic examples, not forecasts, measured results or supplier quotations.

Use net savings after maintenance, consumables, financing, supervision and expected downtime. Labor reassignment is not automatically a payroll reduction. If a higher-priced platform saves additional commissioning time, removes a vision integration project or produces more good units per shift, include those benefits explicitly. Calculate payback as total installed cost divided by monthly net benefit, then test sensitivity to uptime and changeover frequency.

Advantages and limitations

FAIRINO's main limitation is that low arm price does not remove application engineering, validation or support requirements. The rival's main commercial limitation in this comparison is its higher documented hardware reference; the extra capability must solve a real process need. Both require a supplier-backed assessment of the loaded motion path and the specific factory environment.

Which robot should you choose?

Choose FAIRINO FR5 when the real cell fits its rated load and 922 mm reach, and acquisition cost is a major constraint. Shortlist ESTUN S7-80 Eco when the heavier tool-plus-part load needs its additional rated payload. Request a loaded cycle demonstration and a fixed-scope cell quote from both suppliers.

Frequently asked questions

Are these robots in the same payload category?

ESTUN S7-80 Eco has 2 kg more headline rated capacity. That difference belongs to tooling as well as the part: a dual gripper, adapter, camera and cable allowance can consume it before the workpiece is added.

What is the current FAIRINO FR5 price?

The FAIRINO USA product pages list $8,699 USD as checked November 2, 2026. Confirm the written package, taxes, delivery, tooling and commissioning before purchase.

What price is used for the ESTUN S7-80 Eco?

Xiangjing publishes a model-specific S7-80 Eco marketplace range of $8,880–$11,000 USD per set, minimum quantity one. The $8,880 value is the advertised lower endpoint used for the arithmetic, not a fixed configured quote. The listing title mentions an OnRobot gripper, so included robot, controller, pendant and tooling must be confirmed individually. Manufacturer specifications govern the engineering table; the seller copy contains a conflicting repeatability figure. This reference excludes any unconfirmed US taxes, freight, commissioning and support.

Which robot reaches farther?

The FAIRINO FR5 reaches 122 mm farther on the published figures. The extra margin can help with a recessed fixture, but tool length, joint limits and approach angle still require simulation.

Which has better published repeatability?

FAIRINO FR5 publishes the tighter repeatability figure. This may help taught-point handling, but it does not establish better absolute accuracy, loaded path tracking or finished-part quality.

Does the listed payload include the gripper?

Yes. The tool, fingers, adapters, sensors, cable allowance and workpiece all contribute to moving payload. Check inertia and center of gravity as well as mass; do not assume a separately advertised maximum FAIRINO load applies at every speed and pose.

Can either robot work beside people without a fence?

That depends on the complete application. The tool, workpiece, trapping points, stopping distance and operating mode determine the required safeguards. Robot certification alone does not approve a machine-tending or palletizing cell.

Which is the better purchase?

Choose FAIRINO FR5 when the real cell fits its rated load and 922 mm reach, and acquisition cost is a major constraint. Shortlist ESTUN S7-80 Eco when the heavier tool-plus-part load needs its additional rated payload. Request a loaded cycle demonstration and a fixed-scope cell quote from both suppliers.
