High-precision grease-lubricated bearings specifically engineered for KYKY FF250/1500 turbomolecular vacuum pumps, significantly improving stability and service life during continuous high-speed operation. Includes detailed technical specifications, application cases, and professional Q&A.

1、Specialized High-Precision Bearings for KYKY FF250/1500 - Breaking Through Vacuum Equipment Performance Limits

In semiconductor manufacturing, photovoltaic coating and other advanced fields, KYKY FF250/1500 turbomolecular vacuum pumps face bearing wear challenges from continuous high-speed operation. Conventional bearings typically show performance degradation after 8,000 hours, affecting vacuum levels and equipment stability. Our specialized high-precision bearings extend service life beyond 15,000 hours through material innovation and process optimization.

Average service life extended to 22 months

Vacuum level fluctuation reduced by 68%

Annual maintenance cost per unit decreased by ¥150,000

Unexpected downtime incidents reduced by 83%

Professional Q&A (FAQ)

Q: What are the key advantages over standard bearings?
A: Uses vacuum-degassed steel (impurities ≤0.001%); special heat treatment achieves HRC62-64 hardness; precision machining ensures roundness ≤0.5μm.

Q: How to determine when replacement is needed?
A: Replace when: ① Vibration >3.5mm/s ② Noise increase >5dB ③ Vacuum fluctuation >10% ④ Abnormal temperature rise >15℃.

Q: Any special installation requirements?
A: Must use hydraulic tools in clean environment (≤Class 100), followed by 8-hour low-speed run-in (≤3000rpm).

Q: What's the grease replenishment interval?
A: Normal conditions: replenish every 6000 hours, complete replacement every 12000 hours. High-temp (>80℃) environments reduce intervals by 30%.

Q: Are different preload options available?
A: Light (20N), medium (40N default), and heavy (60N) preload versions.

Q: How to protect bearings during power failures?
A: Recommend backup power modules to ensure minimum 5-minute slowdown lubrication.

Q: What's the lead time?
A: Standard models 7 days, custom orders 15 days, expedited 72-hour service available.

Q: Compatibility with other pump brands?
A: Tested compatible with Edwards/Pfeiffer equivalents (dimensional tolerance ≤0.005mm).

Q: How to verify authenticity?
A: Each bearing has laser anti-counterfeiting code verifiable on our website, with 3-year traceability.

Q: How to address abnormal vibration?
A: Immediately check: ① Rebalance ② Verify shaft fit ③ Eliminate external vibration sources ④ Contact support if needed.
