A leading semiconductor manufacturer using KYKY FF300 pumps experienced vacuum degradation due to bearing corrosion. After switching to genuine KYKY corrosion-resistant bearings:
✔ Vacuum restored to 5×10⁻⁷ Pa
✔ Bearing life extended from 12,000 to 22,000 hours
✔ Annual maintenance costs reduced by 30%
FF100 pumps in a national research facility exhibited excessive vibration due to bearing wear. After OEM bearing replacement:
✔ Vibration reduced from 0.8mm/s to below 0.15mm/s
✔ Continuous operation for 18 months without performance degradation
Q1: Difference between OEM and aftermarket bearings?
A: Genuine bearings use proprietary materials and coatings, offering superior corrosion resistance, balancing precision, and lifespan.
Q2: How to identify bearing replacement needs?
A: Check bearings when observing vacuum degradation, abnormal vibration, temperature rise, or increased noise.
Q3: What if vacuum doesn't meet specs after replacement?
A: Verify seal integrity, installation orientation, and allow 72-hour run-in period.
Q4: Is regular grease replenishment needed?
A: Genuine bearings feature long-life lubrication and normally require no replenishment.
Q5: How is corrosion resistance verified?
A: Through 500-hour salt spray testing (ASTM B117 standard) with zero corrosion.
Q6: What's the shelf life of stocked bearings?
A: Unopened bearings can be stored for 5 years, but optimal performance is guaranteed within 3 years.
Q7: Do you offer on-site replacement services?
A: We provide remote guidance, on-site repair, or factory maintenance - contact technical support for options.
Q8: Common causes of bearing failure?
A: Primarily caused by lubricant contamination (36%), improper installation (28%), and overloading (18%).
Q9: How to extend bearing life?
A: Maintain clean environments, avoid frequent start-stop cycles, and regularly monitor vibration/temperature.
Q10: Are bulk purchase discounts available?
A: 5% discount for 5+ units, 8% for 10+ units, with customized solutions available for 30+ units.
Daily: Record bearing temperature and vibration values
Monthly: Conduct spectrum analysis for early fault detection
Quarterly: Clean and inspect bearing condition
Annually: Perform complete disassembly inspection or preventive replacement
