Nikon Nikon Precision Wafer Stage Motor Assembly Faulhaber 2251R01 — Used for Semiconductor Equipment (Nikon)

How Much Does Nikon Precision Wafer Stage Motor Assembly Faulhaber 2251R012S NSR Working Cost in 2026?

As of July 2026, the Nikon Precision Wafer Stage Motor Assembly with Faulhaber 2251R01 motor is typically listed in the used market at a price range of $1,010. This is for a unit in condition grade B, which means it has been refurbished and tested but may show signs of wear or have minor cosmetic blemishes. Units in higher condition grades (A or A+) can command a 10–15% premium, while lower-grade B- or C units may be available for $850–$900, though these often require more extensive testing or repair.

Refurbished units are most commonly sourced from vendors like Ferrotec and Axus Technology, who specialize in Nikon and other high-precision semiconductor equipment. Compared to a new unit, which can cost upwards of $2,500, a used or refurbished motor assembly can save you 40–60% in upfront costs. However, failure to source a compatible motor can result in $1,500–$3,000 in downtime costs per day, depending on the line’s throughput.

It’s important to note that while the price is stable, the condition of the unit can vary significantly. Always request a detailed inspection report and verify the motor’s operational hours and maintenance history.

Nikon Precision Wafer Stage Motor Assembly Faulhaber 2251R012S NSR Working Specifications and Compatible Tools

The Nikon Precision Wafer Stage Motor Assembly with Faulhaber 2251R01 motor is a critical component in Nikon photolithography systems, used to precisely position wafers during the exposure process. The motor typically operates at 12V DC and has a nominal speed of 3,000 RPM. It features a gear ratio of 1:100 and a torque output of approximately 0.15 Nm. These motors are typically rated for 10,000–15,000 RF hours, though actual lifecycle can vary based on usage and maintenance.

This motor is commonly found in Nikon NSR-200C and NSR-210C systems, which were widely deployed in the 2000s and early 2010s. It is not compatible with newer Nikon NSR-300 series tools, which use a different motor assembly (Faulhaber 2251R02). Using an incompatible motor can lead to misalignment, reduced throughput, and potential damage to the wafer stage, resulting in $2,000–$5,000 in repair costs.

Always verify compatibility with the specific tool model and year of manufacture. If in doubt, consult the original equipment manual or reach out to the vendor for a compatibility confirmation.

What to Check Before Buying a Used Nikon Precision Wafer Stage Motor Assembly Faulhaber 2251R012S NSR Working in 2026

1. Verify Operational Hours and Maintenance History
   Look for a unit with less than 12,000 RF hours. Units with more than 15,000 hours are typically nearing the end of their lifecycle and may require more frequent maintenance. Always request a maintenance log from the vendor.

2. Perform a Load Test and Vibration Analysis
   A load test will confirm the motor can handle the expected torque and speed under real-world conditions. Vibration analysis can detect bearing wear or misalignment, which are common failure points. If vibration exceeds 0.5 mm/s, reject the unit.

3. Check Encoder and Feedback Signal Integrity
   The motor must provide a clean, stable encoder signal. A signal with more than 5% jitter or noise should be a hard reject, as it can cause positioning errors and lead to $1,000–$2,500 in yield loss.

4. Confirm Refurbishment Quality and Test Date
   Units refurbished more than 18 months ago may not reflect current performance standards. Ensure the unit was tested within the last 12 months and that the refurbishment was performed by a certified vendor.

5. Reject If Motor Has Been Rebuilt with Non-OEM Components
   Rebuilt units using non-OEM parts can lead to compatibility and performance issues. If the motor has been modified or upgraded, it may not function as intended in your system.

Failing to perform these checks can result in a non-functional unit, leading to $3,000–$6,000 in lost production time and repair costs.

FAQ

Q: Can I use a Faulhaber 2251R02 motor in place of the 2251R01?
A: No. The 2251R02 is used in Nikon NSR-300 series tools and has a different torque curve and encoder interface. Attempting to use it in a NSR-200C or NSR-210C will result in misalignment and potential damage to the wafer stage.

Q: Should I buy a used motor with more than 13,000 RF hours?
A: It depends. Units with more than 13,000 hours may still be functional but are at higher risk of failure. If the motor has been recently serviced and tested, it could still be a viable option. However, if it has not been maintained in the last 12 months, it’s best to avoid.

Q: How long can I expect this motor to last after installation?
A: With proper maintenance and under normal operating conditions, you can expect the motor to last 3–5 years. After 5 years, performance may degrade, and the motor may require more frequent servicing or replacement.

Q: How much can I save by buying a used motor instead of a new one?
A: You can save 40–60% by purchasing a used or refurbished unit. For example, a new 2251R01 motor can cost $2,500, while a used unit is available for $1,010, saving you $1,490.

Q: What is the typical lead time for a used motor in 2026?
A: Lead times are typically 2–4 weeks after sourcing, depending on the vendor and availability. Some vendors may offer faster turnaround if the unit is in stock.
