FAIRINO FR5 vs. SIASUN SCR5: 5 kg Cobot Comparison
Updated: Nov 2
5 kg-class collaborative robot comparison • Payload, reach, precision and U.S. pricing
🤖 Overview: The SIASUN SCR5 from SIASUN and the FAIRINO FR5 compete in the 5 kg-class cobot segment. The SIASUN SCR5 offers 5 kg of rated payload, 800 mm of reach and ±0.02 mm repeatability. The FAIRINO FR5 answers with 5 kg, 922 mm and ±0.02 mm at a published U.S. price of $8,699. This comparison separates published specifications from the points that should be confirmed in a demo or quotation.

🏋️ Payload: 5 kg vs. 5 kg
Both arms share the same 5 kg rating, so the decision moves to reach, precision, ecosystem and price.
📏 Reach: 922 mm vs. 800 mm
FAIRINO FR5 reaches 122 mm (about 15%) further. Extra reach can let one robot serve a machine, an infeed and an inspection station without a riser or linear track, while a shorter arm keeps the swept area compact and simplifies guarding. Simulate both robots in your actual cell layout.
🎯 Repeatability and Precision
Both publish ±0.02 mm, which is sufficient for most handling and assembly tasks.
🛡️ Environment and Safety
The FAIRINO FR5 is offered with IP54 protection and an IP65 option. Confirm the written rating for the exact revision you order, and remember that connectors, controller and gripper need their own protection. Every collaborative application still needs a risk assessment under ISO 10218 and ISO/TS 15066.
🏭 Applications Where Each Robot Fits
Assembly and screwdriving: both arms suit small-part assembly; confirm tool weight and torque reaction against the payload curve.
Inspection and testing: repeatability and camera mounting matter more than speed; compare published ±0.02 vs ±0.02 mm.
Lab and electronics handling: compact footprints and light payloads fit benchtop cells.
💰 Price and Total Cost of Ownership
FAIRINO USA lists the FAIRINO FR5 at $8,699. The SIASUN SCR5 is listed from $18,000 (indicative list price), so the published arm prices differ by about $9,301 (roughly 52% less for the FAIRINO). Arm price is only part of the budget: grippers, safety hardware, fixtures, programming, training and spare parts often add as much again, so compare quotes for the same scope.
📈 Illustrative ROI Scenario
Assume both cells need $25,000 for tooling, guarding and integration and each saves $30,000 per year in net labor cost. The FAIRINO FR5 cell would total about $33,699, a simple payback of roughly 1.1 years. The SIASUN SCR5 cell would total about $43,000, or roughly 1.4 years. These figures are illustrative; model your own cell.
✅ Buyer's Evaluation Checklist
Total gripper + part mass and center of gravity against each payload curve
Reach to every pick, place and inspection point in a CAD simulation
Written IP rating, warranty and delivery terms for the exact revision
Measured cycle time with real parts, including fault recovery
Installed-cell quotes for the same scope from both suppliers
🏁 Conclusion
The FAIRINO FR5 stands out for value, with 5 kg payload, ±0.02 mm repeatability and a transparent $8,699 price. The SIASUN SCR5 brings the SIASUN ecosystem at a higher published price. Shortlist the arm whose reach, payload and integration needs match your cell, then confirm with a trial and an installed-cell quote.
