Selecting a used industrial robot arm means balancing the upfront price against the work it will have to do in your cell. Some automation lines need a compact unit that can slide into a tight space; others demand a larger articulated platform with a bundled controller or a longer reach. This comparison covers four distinct used machines-an Epson arm, a Fanuc robot with controller, and two Staubli six-axis arms-with listed prices spanning USD 1,995.00 to USD 7,999.99. Use the table and decision guide to see which one fits the job you have in mind.
Quick take
The SEIKO EPSON C4-A901S is the lowest-priced arm in this set and a good place to start if you already have a controller. The Fanuc S-10 bundles its arm and controller in one package, making it a convenient candidate for heavy-duty work. The Staubli TX90 ESD offers a larger European-built platform with an ESD designation, though the listing is upfront about wear and a leaking joint. The Staubli TX2-60L is the most expensive unit, but it's also the only one explicitly described as tested and working.
Listed price comparison
| Product | Listed price | Price bar | Key specs |
|---|---|---|---|
| SEIKO EPSON C4-A901S INDUSTRIAL ROBOT ARM | USD 1,995.00 | Payload 4 kg, arm-only | |
| Fanuc Robotics Industrial Robot Arm & Controller Model S-10-RS-7RHUC2 F-18427 | USD 1,999.99 | 6-axis, with controller | |
| Staubli Faverges TX90 ESD 6-Axis Industrial Robot Arm 100cm Reach 6 kg Payload | USD 2,999.99 | 100 cm reach, 6 kg payload | |
| Staubli TX2-60L 6-Axis Articulated Industrial Robot Arm 920mm Reach 4.5kg | USD 7,999.99 | 920 mm reach, 4.5 kg payload, tested working |
Decision matrix
- Choose the SEIKO EPSON C4-A901S if you want the lowest listed price and a simple, compact arm for payloads up to 4 kg.
- Choose the Fanuc S-10-RS-7RHUC2 if you want an arm and a controller together in one purchase, especially for heavier industrial assignments.
- Choose the Staubli TX90 ESD if your priority is the longest reach in this group (100 cm) and a 6 kg payload, and you can handle visible wear and a noted oil leak.
- Choose the Staubli TX2-60L if you prefer the confidence of a unit that was pulled from a working environment and tested before listing, and your budget reaches the top of this range.
Product notes
SEIKO EPSON C4-A901S INDUSTRIAL ROBOT ARM
The SEIKO EPSON C4-A901S is an arm-only unit in used condition, which makes it the leanest option here for a buyer who wants to start with just the arm. The seller emphasizes genuine product, fast free delivery, a 30-day period, and a payment deadline of three days through eBay Managed Payment Service, so the purchase terms are clearly laid out. Its compact form factor is suitable for lighter automation tasks, but the lack of a bundled controller means you'll need to source one separately, adding to your integration work. If you already have a control system and need a straightforward arm, this is a solid entry point.
Fanuc Robotics Industrial Robot Arm & Controller Model S-10-RS-7RHUC2 F-18427
The Fanuc S-10 package is the only combo in this comparison that includes both the arm and its controller. According to the listing, this 1994 Japanese-built system was designed for heavy-duty material handling, welding, or palletizing, with a design ethos built around "million-cycle" durability. The straightforward R-J series control architecture is a selling point for integrators familiar with Fanuc's older systems. On the downside, you're committing to a legacy machine, so you'll want an experienced robotics technician to evaluate the controller and arm before installation. It's a legacy platform, so an experienced integrator should inspect both the arm and controller before you put them into production.
Staubli Faverges TX90 ESD 6-Axis Industrial Robot Arm 100cm Reach 6 kg Payload
The Staubli Faverges TX90 ESD is a six-axis arm with an ESD designation, suggesting it was configured for environments where electrostatic discharge is a concern. The listing is candid about its condition: one of the first two joints is leaking oil, the side is stained, and there are scuffs and scratches from prior use on the custom end effector. It comes in non-original packaging, and the seller requests shipping details such as residential area, dock or forklift, and zip code to provide an estimate. This is a project arm for a buyer who wants a Staubli platform and is ready to handle mechanical upkeep and freight coordination.
Staubli TX2-60L 6-Axis Articulated Industrial Robot Arm 920mm Reach 4.5kg
The Staubli TX2-60L is the only unit here explicitly described as tested and working after being pulled from a working environment. The listing states that only the items in the photos are included, and it will ship the same day on a professionally packaged pallet. That tested status, combined with the 920 mm reach and 4.5 kg payload, explains its position at the top of the price range. The trade-off is the premium you pay for that confidence, so it makes the most sense when your application needs the reach and payload and you want to minimize the risk of a dead-on-arrival unit.
Final recommendation
If your goal is a low-cost, no-frills arm for basic handling tasks, start with the SEIKO EPSON C4-A901S. If you need an arm and controller delivered together, the Fanuc S-10 is the most complete package. For ESD-sensitive work, the Staubli TX90 ESD is worth a close look. And if you want the peace of mind that comes with a tested, working unit and your budget allows, choose the Staubli TX2-60L. Match the machine to your cell, and you'll know exactly which of these used robot arms deserves the spot on your floor.
