Staubli RX90 vs Fanuc S-10: Choosing a Used 6-Axis Robot Arm

Two used 6-axis robot arms, two price points: the Staubli RX90 with CS7 controller at $2,499.99 and the Fanuc S-10 arm at $1,999.99. Here's which one fits a production line.

Last updated Aug 17, 2026

Choosing between two used industrial robot arms doesn't have to be a gamble, but it does mean weighing control architecture, mechanical scope, and listed price. The Staubli RX90 arrives as a 6-axis arm paired with a CS7 controller and a Stäubli label, while the Fanuc Robotics S-10-RS-7RHUC2 is a Japanese-built arm assembly with a different control setup and a $500 lower list price. Both are used, but they target different buyers.

Quick Verdict

If your line already favors Stäubli control systems or you want a matched arm-and-controller package, the Staubli RX90 is the straightforward choice. If you prefer a lower listed price and a Japanese-built arm assembly that's described for heavy-duty material handling, welding, and palletizing, then the Fanuc S-10 deserves your attention.

Where Each Product Wins

Staubli RX90 CS7: This is the pick when you need a dedicated controller package from a European robotics name. The listing includes the arm and the CS7 controller, and the control type is explicitly listed as CS7. The unit is used surplus from American Industrial Supply Co., with a dent on the corner and a missing key-so cosmetic condition is a factor to note.

Fanuc S-10-RS-7RHUC2: This wins on price and mechanical emphasis. It's listed at $1,999.99, and the description highlights a rugged design for heavy-duty applications. Built in Japan in 1994, the robot arm assembly is positioned as a reliable workhorse. The control type is listed as Arm, so you'll be working with an arm-focused setup rather than a separate CS-style controller.

Product Notes

Staubli RX90 CS7 6-Axis Industrial Robot Arm Controller (1997)

Staubli RX90 CS7 6-Axis Industrial Robot Arm Controller 1997 *READ

This listing from American Industrial Supply Co. includes the Staubli RX90 arm and CS7 controller in used surplus condition. It's a solid route for operators who want a Stäubli-branded system with the controller as an explicit part of the package. The unit is from 1997 and does show signs of handling: a dent on the corner and a missing key. That's a concrete limitation to weigh against the $2,499.99 list price. If you're building a line around Stäubli controls, this gives you the arm and the controller in one buy, with the CS7 control type making it a coherent system rather than a spare-part gamble.

The Fanuc S-10 is the lower-priced option at $1,999.99, but it brings a different kind of presence. It's a 1994 Japanese-built 6-axis arm assembly, and the seller's description emphasizes million-cycle durability and heavy-duty use cases like material handling, welding, and palletizing. The control type is listed as Arm, which means you're looking at an arm-focused package rather than a standalone controller. For operations already aligned with R-J series control architecture, this can be an effective match. The used condition is acknowledged, but the mechanical design is the selling point, especially if your priority is a rugged arm at a lower absolute cost.

Final Choice by Use Case

Pick the Staubli RX90 when you need a matched arm-and-controller system and are comfortable with the cosmetic wear. Pick the Fanuc S-10 when you want the lower listed price and a Japanese-built arm designed for heavy-duty work. Both are serious used industrial robots; your decision comes down to control style, physical scope, and budget.
