S-420S Information

As part of a family of six-axis articulated electric servo driven robots, the FANUC S-420S robot is designed to handle a variety of spot welding, machine load and un-loading, sealing, material handling, and parts transfer. This robot has a heavy wrist load capacity.

There are several robot models available in the FANUC S-420 series, including the S 420S. They feature absolute encoder positioning and brakes on all axes and a slender profile. The heavy-duty machine tool-type construction of the s420s built to withstand and operate in the most severe plant environments. The arm joints are anti-friction bearing mounted and there are safety limits switche for overtravel protection.

The S420S can use either an RJ or RJ2 FANUC robot controller.  

There are also used FANUC S-420S robots available through RobotWorx. Every used S-420S has gone through an intense refurbishment process, bringing it back to mint condition, and comes with the RobotWorx Value Package.

 Whether you purchase a new or used S-420s robot, it has the largest range of motion and least back space in its class along with a compact body; it will not disappoint!
