FAQ

1. When to replace bearings?

Consider replacement when experiencing abnormal vibration, speed reduction, or failure to reach specified vacuum levels.

2. Replacement interval?

Recommended every 3-5 years under normal conditions, depending on operating environment.

3. Post-installation procedures?

Requires 48-hour low-speed run-in and dynamic balance recalibration.

4. Regular grease replenishment needed?

Sealed design eliminates need for grease replenishment during normal service life.

5. How to monitor lubrication condition?

Monitor operating current and vibration spectrum changes.

6. Can bearings operate in atmosphere?

Avoid prolonged high-speed operation in atmospheric conditions - severely reduces lifespan.

7. If vacuum performance declines after replacement?

Check seal condition and perform proper bake-out degassing.

8. Storage requirements?

Store in dry, clean environment at 15-25℃, ≤40% RH.

9. Can different bearing batches be mixed?

Not recommended - use same batch for consistent performance.

10. How to choose professional service?

Select authorized providers with molecular pump balancing equipment.
