Technical Specifications (Table Format) 

Case Study

A semiconductor manufacturer using KYKY FF160/620C turbo pumps for wafer coating experienced bearing wear due to prolonged high-load operation, leading to vacuum instability. After replacing the bearings with upgraded grease-lubricated versions, vacuum performance improved by 30%, noise reduced by 15%, and maintenance intervals extended.

Frequently Asked Questions (FAQ)

1. Do KYKY FF160/620C bearings require regular greasing?

No, these bearings are designed for long-term grease lubrication and typically do not require additional greasing for at least 2 years.

2. How to determine if bearings need replacement?

Excessive noise, increased vibration, or a noticeable drop in vacuum levels indicate potential bearing wear.

3. Is dynamic balancing required after bearing replacement?

Yes, dynamic balancing is mandatory to ensure smooth high-speed rotor operation.

4. Can oil lubrication be used instead?

No, the FF160/620C is designed for grease lubrication. Switching to oil may cause seal failure.

5. What is the maximum operating temperature?

The bearings can withstand up to 120°C, but prolonged exposure to high temperatures reduces lifespan.

6. What precautions should be taken during installation?

Maintain a clean environment to prevent contamination.

Use specialized tools for press-fitting (avoid hammering).

Ensure proper axial preload.

7. What are common causes of bearing failure?

Grease degradation

Overloading or excessive vibration

Contaminant ingress

8. How to extend bearing service life?

Minimize frequent start-stop cycles.

Keep the vacuum system clean.

Regularly monitor vibration and temperature.

9. Are these bearings compatible with other pump brands?

No, they are exclusively designed for KYKY FF160/620C pumps.

10. Where to purchase genuine OEM bearings?

Always source from KYKY-authorized distributors or service centers to ensure compatibility.

Conclusion

The KYKY FF160/620C grease-lubricated bearings are critical for optimal turbo molecular pump performance. Proper selection, installation, and maintenance significantly enhance vacuum system reliability. For technical support, consult certified suppliers.
