FANUC SR-6iA

The SR-6iA is a four-axis SCARA that FANUC introduced in 2017 for assembly and packaging work. It's built around planar motion, swinging across a work plane and dropping straight down onto the part. That geometry fits the fast pick-and-place rhythm those lines run.

With 6 kg of payload and 650 mm of reach, it covers the small components and short travels those cells hand it. On dispensing jobs, the rigid arm keeps a taught bead landing consistently through quick cycles. It also handles light machine-tending where parts sit within that planar envelope.

The arm mounts to the floor or a wall, so integrators can tuck it into dense cell layouts. At 30 kg it's light enough to reposition and re-fixture without heavy rigging. It carries an IP20 rating.

It runs on the R-30iB Compact Plus controller and shares its programming with FANUC's six-axis lines, so pendant skills carry straight over. Teams standing up a routine can follow creating a new TP program, and the FANUC parts catalog lists items like a J1 servo motor or wrist unit. FANUC servo alarms such as SRVO-062 route through the same SRVO diagnostics used across the controllers.

Its planar kinematics trade orientation flexibility, so work that needs the tool tilted through compound angles sits outside its range. It's also not built for a large vertical stroke, which keeps it on flat, in-plane tasks.

What sets it apart on the line is 0.01 mm repeatability, holding small parts to the same spot cycle after cycle. For a four-axis arm aimed at fast assembly, that precision is its standout number.
