FANUC S-420i
S-420i Information

The FANUC S-420i line of robots is engineered for maximum performance and reliability in the automotive body shop.

The FANUC S420 RJ3 features an electric servo-driven design for high speed and heavy payload processes.

The large work envelope allows processing of large fabrications. The combined mechanical unit and robot controller reduces floor space, point-to-point wiring, and installation costs. High motion speeds reduce time between welds.

The S420i RJ3 features a flexible and expandable I/O system internal to the controller. The FANUC S 420 mechanical construction also provides precise positioning and high motion speed. Sealed bearings and drives provide protection and improve reliability.

RobotWorx also offers a variety of reconditioned robots, including the used FANUC S-420i. All of the reconditioned S-420i robots have gone through an intense refurbishment process, bringing it back to mint condition. Additionally, any used FANUC S-320i purchased comes with the RobotWorx Value Package.
