Choosing a used robot for an industrial automation cell is often a split between price and versatility. In the used industrial robotics cobots market, two used robots capture that split perfectly: a compact IAI 2-axis screwdriver linear arm and a Universal Robots UR5e collaborative robot. The IAI is a narrow, purpose-built machine; the UR5e is a broad generalist that can be retrained. The right pick depends on whether your job is a fixed linear fastening task or a workflow that changes regularly.
Quick verdict
Buy the IAI 2-axis screwdriver arm if you have a dedicated Y/Z screwdriving path and you are comfortable working with the control and servo-drive wiring. Buy the Universal Robots UR5e if you need a flexible cobot that can rotate between machine tending, assembly, picking, and lab tasks. The IAI is the focused, low-cost option; the UR5e is the flexible investment.

Where each product wins
The IAI wins if...
Your process is a repetitive screwdriving or linear positioning sequence along a set path. The arm is already built around that kind of motion, and its low price leaves room to buy the missing servo drive for the screwgun motor. It fits a builder who wants a low-cost way to automate a narrow task and can handle the wiring details.
The UR5e wins if...
Your process is not fixed. The UR5e is the more adaptable machine. It handles delicate insertion and polishing as well as heavier pick-and-place and machine tending, and it can be reprogrammed from one task to another. It is the better choice when one robot needs to do several jobs, and the higher price buys real flexibility.
A closer look
IAI 2x Axis Screwdriver Linear Robot Arm 8" Z 4" Y Movement DSRC CAN Controllers
This used arm gives you a dedicated linear platform for screwdriving: two axes with 8 inches of Z travel and 4 inches of Y travel, plus DSRC CAN controllers and a Yaskawa SGME-01AFNS11 screwdriver servo motor. Pulled from a working surplus line, it is the cheaper path into a compact screwdriving cell-good when you already have a fixed Y/Z path and need a repeatable way to move a screwdriver through it. The catch is in the wiring: the actuators have CAN controllers, but the protocol is not confirmed, and no servo drive is included for the screwgun motor, so you will need to source one. For a builder comfortable with CAN and servo drives, the $499.99 price makes it an affordable, focused start.
Universal Robots UR5e Collaborative Robot (Cobot) - 5 kg Payload, Low Hours
The UR5e is the versatile option here. It has six rotating joints, a 5 kg payload, an 850 mm reach, and a compact Ø149 mm footprint that mounts in any orientation. The integrated 6-axis force/torque sensor and ±0.03 mm repeatability make it capable of force-sensitive work like insertion, polishing, and delicate handling, while the 12-inch PolyScope touchscreen lets you hand-guide the arm to teach waypoints. It is a used unit with low hours, and the price reflects that investment level: $21,000. That buys a lot of flexibility-machine tending, pick-and-place, packaging, screwdriving, dispensing, quality inspection, and lab automation-but it is a far bigger commitment than the IAI's asking price, so the UR5e only makes sense if your workload will actually use its range and sensing.
Final choice by use case
Pick the IAI linear screwdriver arm when you are setting up a single-purpose station and the task is essentially a screwdriver riding through a fixed Y/Z path. Keep the setup cost low and let the arm stay dedicated to that motion.
Pick the Universal Robots UR5e when your cell needs a robot that can adapt: one day tending a machine, the next doing delicate handling or inspection. The higher price is justified by force sensing, teachable programming, and the ability to remount the arm in different orientations.
