Used Metal Bellows for Semiconductor Equipment

How Much Does a Used Metal Bellows Cost in 2026?

Used metal bellows (edge weld or corrugated) for semiconductor tools typically range from $500 to $2,500 in 2026, depending on size, material (316SS vs 304SS), and OEM. Refurbished units with certified vacuum integrity testing cost $800 to $3,000, offering 40–70% savings over new parts (which exceed $5,000 for high-vacuum grades). Caveat: Bellows with >100,000 actuation cycles or cracks in weld seams (visible under 5× magnification) should be rejected, as they risk vacuum failure during thermal cycling. Always request a pressure decay test log (≤1×10⁻⁵ Torr leakage acceptable).

Metal Bellows Specifications and Compatible Tools

Key specs: 316 stainless steel construction, 10⁻⁶ Torr vacuum rating, 400–800°F operational range, 0.020–0.060” wall thickness. Commonly used in PVD/CVD tools for motion isolation. Compatible with:

• Applied Materials Centura (2005–2012, part 6670-00123)
• Lam Research Endura (2008–2015, part 5580-00212)
• Tokyo Electron HARP (2010–2017, part TEH-0045B)
  Exclusion: Not compatible with ASMI Fusion-F3000 (part 8892-0001) due to non-standard flange threading (ISO 9467 vs ISO 2861). Verify tool’s pressure requirements—bellows rated <10⁻⁵ Torr are mandatory for ALD systems.

What to Check Before Buying a Used Metal Bellows in 2026

1. Visual inspection: Reject bellows with >2 corrosion pits >0.010” deep (use a 5× loupe or digital microscope).
2. Vacuum test: Perform a helium mass spectrometer leak test; leakage >1×10⁻⁷ Torr/sec invalidates the part.
3. Wall thickness: Measure with a micrometer at 3+ points; deviation >15% from OEM spec (e.g., 0.040” ±0.006”) indicates fatigue.
4. Cycle history: Demand documentation of actuation count—bellows with >150,000 cycles in high-vibration environments (e.g., etch tools) are high-risk.
5. Material verification: Use XRF to confirm 31
