FAQ

Frequently asked questions

How much does the FANUC SR-3iA cost? +

The FANUC SR-3iA price is normally available by project quote rather than as one fixed global list price. The final cost can depend on the standard SR-3iA or food, environmental, upside-down or three-axis variant, controller, software options, end effector, vision, fixtures, safety equipment, integration, installation, training, shipping, taxes, warranty and regional support. A robot arm or mobile system is only one part of the deployed solution. Two quotations can therefore look very different: one may cover mainly the core hardware, while another may include tooling, guarding, programming, commissioning and production acceptance.

Buyers should compare the total installed cost and the expected output, not only the robot line item. Ask the supplier to state what is included, what the customer must provide and which assumptions were used for payload, reach, cycle time and environment.

You can request a FANUC SR-3iA quote through Anton Robots to compare the complete package, delivery terms and support before ordering. The selected supplier should confirm the specification in writing and demonstrate the critical cycle or process before the buyer approves final production acceptance.

Where can I buy the FANUC SR-3iA? +

You can buy, order or request the FANUC SR-3iA through Anton Robots. We help buyers check the correct commercial route, compare the available package, understand what is included and decide whether the robot fits the intended application. FANUC SR-3iA is currently offered by FANUC through direct sales and authorised automation integrators. Before ordering, confirm the standard SR-3iA or food, environmental, upside-down or three-axis variant, controller, mounting, payload, reach, end effector, software, safety, integration and local service.

This matters because the same model name can appear in a bare-hardware quotation, a partially engineered package or a complete turnkey cell. The lowest headline price is not always the lowest-risk purchase if tooling, programming, installation or support are omitted. To begin, request a FANUC SR-3iA quote and Anton Robots can help compare the robot, application package, shipping, warranty and support.

Before choosing a supplier, verify that it is authorised or technically capable of supporting the destination and application. Ask who owns the integration, who provides commissioning and who responds after delivery. A clear responsibility matrix is especially important when the robot, tool and safety system come from different companies.

Where can I find a FANUC SR-3iA for sale? +

You can find the FANUC SR-3iA for sale through the manufacturer, authorised robot integrators, industrial automation suppliers and specialist marketplaces such as Anton Robots.

However, finding a listing is only the first step. Confirm the exact suffix or configuration, controller generation, condition, included cables, teach pendant, licences, tooling, safety equipment and service coverage. A listing described only by the family name may not identify the payload, reach, environment version or mounting arrangement required for your process. For professional buyers, compare the total delivered and commissioned cost rather than the arm price alone.

If you need the robot for a production deadline, also verify manufacturing lead time, integrator capacity, acceptance testing and spare-parts availability. Contact Anton Robots to review a FANUC SR-3iA offer before purchasing. Request a formal specification rather than relying on a marketplace title or promotional image. The model suffix, controller, environment version and included application package should match the quotation. Stock claims should be tied to a serialised unit or confirmed production allocation, not a generic product page.

Can I get a quote for the FANUC SR-3iA? +

Yes. You can request a quote for the FANUC SR-3iA through Anton Robots.

A useful quotation should identify the standard SR-3iA or food, environmental, upside-down or three-axis variant, controller, teach pendant or operator interface, software, mounting, SCARA tooling, vacuum or electric gripper, vision, lighting, conveyor tracking and fixtures, safety, engineering, programming, commissioning, training, delivery and warranty. It should also state the assumed workpiece, payload including tooling, centre of gravity, required reach positions, cycle target, utilities and operating environment.

This matters because an apparently inexpensive proposal can become more expensive once omitted hardware, integration, freight, duties or site work are added. Ask for clear exclusions and an acceptance-test plan. Anton Robots can help compare proposals on the same scope so the decision is based on deployable value rather than an incomplete base price. The supplier should be given enough application data to size the system correctly: part drawings, weight, centre of gravity, cycle target, process forces, machine layout, utilities and operator workflow. Without that information, the quotation is only a budget estimate and should not be treated as a deployable commitment.

What is included when you buy the FANUC SR-3iA? +

A typical FANUC SR-3iA package may include the core robot and the items specified by the selected commercial configuration. The exact delivery varies by country, application and integrator, so request a written packing and scope list. Confirm whether the offer includes:

  • Robot mechanical unit in the exact model or variant
  • Compatible controller, teach pendant and cables
  • Required software, communications and licences
  • Scara tooling, vacuum or electric gripper, vision, lighting, conveyor tracking and fixtures
  • Mounting, fixtures, guarding and safety equipment
  • Programming, commissioning and production testing
  • Freight, installation, training, warranty and support

A quotation for the arm alone is not a working automation system. Compare what is included, what remains optional and what the customer must supply. You can request an itemised FANUC SR-3iA package through Anton Robots before buying.

The written scope should distinguish manufacturer-standard hardware from integrator-built equipment and customer-supplied items. It should also define documentation, source-code ownership, electrical drawings, risk assessment, manuals and acceptance testing. These deliverables affect the buyer’s ability to maintain or modify the system later.

Can the FANUC SR-3iA be shipped internationally? +

The FANUC SR-3iA may be available for international delivery, but this depends on the manufacturer’s sales territory, destination, export rules, freight method, local certification, installation needs and support coverage. Industrial robots can require specialist crating, insurance, customs handling, unloading equipment, foundation or mounting preparation and local commissioning.

Before ordering, ask whether the quote includes freight, insurance, customs clearance, import duties, VAT or GST, local delivery, installation and return shipping for warranty work. Also confirm voltage, controller specification, language, safety documentation and whether an authorised service partner supports the destination.

International buyers should compare landed and commissioned cost, not only the factory price. Anton Robots can help request a destination-specific quotation. Confirm that local installation and service can be provided after the robot arrives. A lower overseas price may lose its advantage if the buyer must source rigging, electrical work, safety validation, programming and emergency support separately. The landed price and the commissioned price should be shown as different totals.

Is the FANUC SR-3iA in stock and how long does delivery take? +

FANUC SR-3iA availability and delivery time can change according to the SR-3iA variant, compact controller, tooling, vision, machine-builder capacity and acceptance testing. Some distributors may hold a robot or demonstration unit, while most industrial projects are configured and scheduled after the application is reviewed. Lead time can also be affected by grippers, vision, process equipment, safety hardware, custom fixtures, software, factory acceptance testing, freight and site readiness.

Do not assume an online product page means immediate stock. Ask the supplier to identify whether the robot is new, demonstration, refurbished or build-to-order; the exact controller and variant; the estimated ship date; and the commissioning schedule.

If the robot is required for a shutdown or launch date, include schedule milestones and delay responsibilities in the quotation. Ask for separate dates for robot availability, tooling completion, factory acceptance, shipment, site installation and production acceptance. Delays often come from custom tooling or site readiness rather than the arm itself. The project plan should identify dependencies and the person responsible for each milestone.

What warranty and support should I check before buying the FANUC SR-3iA? +

Before buying the FANUC SR-3iA, confirm the written warranty period, covered components, exclusions, repair location, response process and who pays freight or engineer travel. Review SCARA preventive maintenance, spindle and bellows condition where applicable, controller support, vision calibration and spare tooling.

Also ask whether batteries, wear parts, end effectors, third-party software, customer modifications and process equipment are covered. A robot can remain in service for many years, so long-term controller, teach pendant, motor, gearbox and cable support may matter more than a small difference in purchase price. For a production-critical installation, define escalation contacts, response expectations, backup procedures and spare-parts strategy.

You can contact Anton Robots to compare warranty and support terms before ordering. Support quality should be evaluated against the operational importance of the cell. A training-only robot can tolerate a slower response route, while a production bottleneck may need local spares, remote diagnostics and defined service escalation. Ask how software updates and replacement controller hardware will be managed over the expected life.

Is the FANUC SR-3iA worth buying? +

The FANUC SR-3iA is worth considering if its payload, reach, speed, environment rating and integration ecosystem match the process you need to automate. Its 3 kg payload, 400 mm envelope and ±0.01 mm repeatability make it a strong small-parts SCARA, provided four-axis motion is sufficient.

It is not the right purchase if the task falls outside the robot’s rated load, workspace or process capabilities, or if the business case depends on unrealistic cycle time or unattended operation. The decision should include tooling, safety, engineering, training, maintenance, downtime risk and expected production life. Compare alternatives using the same assumptions and test the actual parts whenever possible.

You can browse other SCARA robots or request application advice through Anton Robots before committing. To judge value, calculate output improvement, labour redeployment, scrap reduction, quality, uptime and changeover benefits against the full installed cost. Include maintenance, consumables and internal engineering time. A robot can be technically capable but commercially weak if the process volume or product stability is too low.

What are the payload, reach and repeatability of the FANUC SR-3iA? +

The standard FANUC SR-3iA has a maximum payload of 3 kg, horizontal reach of 400 mm, vertical stroke of approximately 200 mm and repeatability of ±0.01 mm. FANUC lists four axes and mechanical weight around 19 kg for the standard model.

Specialist food-grade, environmental, upside-down or three-axis configurations may differ. Payload includes the gripper, brackets, sensors and part. Confirm the vertical stroke, wrist rotation, mounting and protection rating needed for the actual cell.

Final sizing should use the complete tool and workpiece, not only the product mass. Verify centre of gravity, wrist inertia, required orientation, acceleration and all critical poses in a 3D study. A robot operating near its limit may deliver less cycle performance and leave little capacity for future product changes. The selected supplier should confirm the specification in writing and demonstrate the critical cycle or process before the buyer approves final production acceptance.

What applications is the FANUC SR-3iA best for? +

The FANUC SR-3iA is well suited to small-component assembly, pick and place, insertion, screwdriving, dispensing, inspection, testing, tray loading and packaging. Its SCARA kinematics are particularly effective for fast planar movement with controlled vertical insertion.

It is useful in electronics, medical devices, automotive components, consumer goods and laboratory automation. It is less suitable for tasks requiring complex six-axis tool orientation or reach around obstacles. The complete system may require vision, feeders, conveyors, nests and quality checks. Test real parts and the required cycle before selecting the robot. The integrator should observe the current process and test representative parts whenever possible.

Variability in presentation, tolerances, surfaces and operator interventions can determine whether the robot meets the target. The application should be defined as a complete workflow, not only a list of robot motions. Document the assumptions used for payload, reach, environment and throughput so later changes can be priced and assessed without weakening the original safety or performance case.

How is the FANUC SR-3iA programmed? +

FANUC SR-3iA supports iRProgrammer, a web-based interface that allows programming from a tablet or desktop computer, with teach-pendant options depending on the controller and package. FANUC controllers can also integrate iRVision, conveyor tracking, I/O and communication networks.

The integrator should provide the program source, backups, user access, calibration files and documentation. Programming effort depends on feeders, part variants, inspection logic and machine interfaces, not only robot motion. Ask who will support future product changeovers and whether offline simulation is included. Ask for program backups, source-code access, electrical drawings, network settings, user permissions and recovery instructions.

The buyer should be able to restore operation after a controller replacement or software fault. Cybersecurity and plant-network approval should also be addressed before the system is connected. Anton Robots can help compare FANUC SR-3iA proposals on the same application scope, including tooling, safety, commissioning, delivery, warranty and local support.

Does the FANUC SR-3iA require guarding? +

FANUC SR-3iA is an industrial SCARA robot and should not be assumed safe for open operation around people. Its light payload is combined with very high speed, creating impact, pinch and trapping hazards.

A risk assessment should cover the robot, gripper, sharp parts, feeders, presses, conveyors and maintenance access. The cell may require covers, fencing, interlocked doors, light curtains, scanners or other safety devices. Food or environmental options do not make the robot collaborative. Safe restart and jam-clearing procedures should be included in the design.

Safety must be validated for the robot, tool, workpiece, process and surrounding machines together. A manufacturer safety function is only one component of the final system. The integrator should provide the risk assessment, safety validation report, operating procedures and training required by the destination workplace. The selected supplier should confirm the specification in writing and demonstrate the critical cycle or process before the buyer approves final production acceptance.

Which FANUC SR-3iA variant should I buy? +

The correct variant depends on mounting and environment. The standard SR-3iA provides 3 kg payload and 400 mm reach. FANUC also offers food-grade or environmental versions with different coatings and protection, upside-down models with a different envelope, and three-axis versions for tasks that do not need wrist rotation. Confirm whether the application requires floor, wall or inverted mounting, secondary-food suitability, wash resistance, bellows, bottom cable exit or a full four-axis wrist.

Do not assume accessories or protection can be added later without affecting certification and cost. Tool selection should be demonstrated with the real part range and expected contamination, wear or surface variation.

Include spare fingers, cups, seals, cables and calibration procedures. Vision performance should be tested under production lighting and at the required throughput, not only in a controlled demonstration. Document the assumptions used for payload, reach, environment and throughput so later changes can be priced and assessed without weakening the original safety or performance case.

Should I buy the FANUC SR-3iA or SR-6iA? +

Choose the SR-3iA when the complete tool and part remain within 3 kg and a 400 mm envelope covers the process. Choose the SR-6iA when you need up to 6 kg payload or 650 mm reach.

The smaller robot can reduce footprint and moving mass, while the larger model provides more flexibility for bigger fixtures and workpieces. Compare cycle time, vertical stroke, wrist inertia, machine layout, protection rating and controller cost. A larger robot is not automatically faster once the real path and payload are considered.

Model both options with the actual cell. Compare alternatives using the same assumptions for tooling, safety, integration, delivery and support. A lower-payload or simpler robot may be better when it achieves the task with less footprint and engineering, while a larger model may provide useful future margin. Document why the selected configuration is the best fit. Anton Robots can help compare FANUC SR-3iA proposals on the same application scope, including tooling, safety, commissioning, delivery, warranty and local support.

What should be included in a FANUC SR-3iA quote? +

A complete FANUC SR-3iA quote should state the exact variant, controller, programming interface, mounting, payload, reach and environmental rating. Include the gripper, vacuum equipment, feeder, vision, lighting, conveyor tracking, fixtures, guarding, electrical panel, programming, commissioning and training.

The acceptance test should define part variants, target cycle, placement accuracy, reject handling and uptime. Also include freight, installation, warranty, spare gripper components and local support. Comparing only the SCARA arm price will not show the true cost of a reliable production cell.

The quote should finish with measurable acceptance criteria such as cycle time, placement accuracy, uptime, changeover time and successful handling of defined part variants. Payment milestones and warranty start should be linked to clear project stages. This converts a hardware purchase into an accountable automation project. The selected supplier should confirm the specification in writing and demonstrate the critical cycle or process before the buyer approves final production acceptance.
