FAIRINO FR3 vs. UFACTORY xArm 6: 3 kg Cobot Comparison
Updated: Nov 2
3 kg-class collaborative robot comparison • Payload, reach, precision and U.S. pricing
🤖 Overview: The UFACTORY xArm 6 from UFACTORY and the FAIRINO FR3 are both shortlisted for 3 kg-class automation cells. The UFACTORY xArm 6 offers 5 kg of rated payload, 700 mm of reach and ±0.1 mm repeatability. The FAIRINO FR3 answers with 3 kg, 622 mm and ±0.02 mm at a published U.S. price of $7,999. This comparison separates published specifications from the points that should be confirmed in a demo or quotation.

🏋️ Payload: 3 kg vs. 5 kg
UFACTORY xArm 6 carries 2 kg more rated payload. In practice, payload includes the gripper, adapter plate, sensors and cabling, so the tool consumes a large share of either rating. Ask both suppliers for the payload curve at your tool offset and orientation.
📏 Reach: 622 mm vs. 700 mm
UFACTORY xArm 6 reaches 78 mm (about 13%) 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
FAIRINO FR3 publishes the tighter repeatability (±0.02 mm vs. ±0.1 mm). For most tending, packaging and handling work both are sufficient; for tight insertions and vision-guided placement, fixturing, TCP calibration and gripper compliance matter as much as the datasheet figure.
🛡️ Environment and Safety
The FAIRINO FR3 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 ±0.1 mm.
Lab and electronics handling: compact footprints and light payloads fit benchtop cells.
💰 Price and Total Cost of Ownership
FAIRINO USA lists the FAIRINO FR3 at $7,999. The UFACTORY xArm 6 is listed from $8,399 (UFACTORY store list price), so the published arm prices differ by about $400 (roughly 5% 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 FR3 cell would total about $32,999, a simple payback of roughly 1.1 years. The UFACTORY xArm 6 cell would total about $33,399, or roughly 1.1 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 FR3 stands out for value, with 3 kg payload, ±0.02 mm repeatability and a transparent $7,999 price. The UFACTORY xArm 6 brings longer reach, more rated payload and the UFACTORY 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.
❓ Frequently Asked Questions
