Robots - Stages - Material Handling — Used AITEC AR-SV3G-100 (AITEC)

How Much Does Used AITEC AR-SV3G-100 Cost in 2026?

The used AITEC AR-SV3G-100 typically lists in the $2,950 range in 2026, depending on its condition and refurbishment history. Units in condition grade B (used but fully functional with minor wear) are most commonly available and fall within this price point. Higher-grade units, such as those with full calibration and recent motor replacements, may cost up to $3,200, though these are rare. Refurbished units from vendors like Ferrotec and Axus Technology are often priced at the lower end of the range, offering 40–60% savings compared to a new AITEC AR-SV3G-100, which can cost between $7,000 and $8,000.

Buying a used unit can save a mid-sized fab up to $4,000 per unit, but failure to verify condition can result in unexpected downtime and repair costs. A single failed stage can halt wafer transport for 8–12 hours, costing $5,000–$8,000 in lost production. Units over 10 years old or with more than 50,000 operational cycles are more likely to require immediate maintenance, so always request a detailed inspection report.

Used AITEC AR-SV3G-100 Specifications and Compatible Tools

The AITEC AR-SV3G-100 is a linear stage used for precise material handling in semiconductor automation systems. It typically features a travel range of 100 mm, a load capacity of up to 5 kg, and a resolution of 1 µm. The stage is commonly used in wafer handling systems and compatible with AITEC’s own robotic arms, such as the AR-3000 series from 2010–2014. It also integrates with third-party systems like the ADEPT V+ series, though compatibility must be verified with the control interface.

Units with more than 80,000 cycles or over 12 years old may experience motor degradation or encoder drift, leading to misalignment and potential wafer breakage. A failed stage can cause a system-wide shutdown, costing $6,000–$10,000 in lost throughput and repair labor. Units not compatible with the AR-3000 series may require a control adapter (part number AR-3000-CA-01), which adds $450–$600 to the installation cost.

What to Check Before Buying a Used AITEC AR-SV3G-100 in 2026

1. Verify Operational Cycles and Age
   Units with more than 70,000 cycles or over 12 years old are high-risk. Request a log of maintenance and cycle count. Units over 10 years old may have outdated motor controllers.

2. Test Motor and Encoder Performance
   Use a laser alignment test and a step-response test to check for drift or lag. A stage with more than 5 µm of drift should be rejected.

3. Inspect for Mechanical Wear
   Look for signs of binding or uneven movement. A stage that requires more than 0.5 N of force to move manually is likely to fail under load.

4. Check Control Interface Compatibility
   Confirm the stage uses a standard RS-485 or CANopen interface. Units with proprietary control boards may require a $400–$600 adapter.

5. Reject Units with Failed Bearings
   If the stage shows visible play in the linear bearings or has a history of bearing replacement, reject it. A failed bearing can cause a catastrophic failure, costing $8,000–$12,000 in downtime and repairs.

Buying a low-quality used stage can lead to a 24-hour system shutdown, costing $10,000 in lost production and repair labor. Always request a 30-day return policy when possible.

FAQ

Q: Can I use the AITEC AR-SV3G-100 with a newer ADEPT V+ robot?
A: Yes, but only if the V+ model is from 2012 or later and has a CANopen interface. Older models may require a $550 control adapter (part number ADEPT-CA-02).

Q: Should I buy a used AITEC AR-SV3G-100 with 65,000 cycles?
A: Yes, if it has been recently serviced and shows less than 3 µm drift. Units with 70,000+ cycles are high-risk and may fail within 6 months.

Q: How long can a used AITEC AR-SV3G-100 last with proper maintenance?
A: With annual motor and encoder checks, a unit can last 8–10 years. Replace bearings every 50,000 cycles and re-calibrate every 3 years to avoid drift.

Q: What’s the difference between used and new AITEC AR-SV3G-100 in terms of performance?
A: New units offer 0.5 µm resolution and 100,000+ cycles before maintenance. Used units in condition grade B typically offer 1 µm resolution and 50,000–70,000 cycles before needing service.

Q: Can I install a used AITEC AR-SV3G-100 in a 2018 fab line?
A: Yes, but you must verify control compatibility. If the line uses a 2018 ADEPT V+ robot, you may need a $550 control adapter. Installation typically takes 4–6 hours.
