Case 1: PV Coating Equipment Vacuum System
Issue: Standard bearings corroded within 3 months in process gas environment
Solution: Stainless steel base + PTFE coated bearings
Result: 18-month service life, 60% reduction in downtime
Case 2: Research-Grade Mass Spectrometer Maintenance
Challenge: Required UHV (10⁻⁸Pa) and low-vibration bearings
Custom Solution: Ceramic hybrid bearings + special damping design
Outcome: 45% noise reduction, 30% sensitivity improvement
Q1: What is the production lead time?
A: 3-4 weeks for standard configurations, 4-6 weeks for special designs (express service available in 10 working days)
Q2: How to verify bearing compatibility?
A: Required information: ① OEM bearing model/drawings ② Shaft/housing dimensions ③ Installation space ④ Operating parameters
Q3: Recommended materials for corrosive environments?
A: Preferred options: ① Stainless steel/ceramic hybrid ② Special coatings ③ Full ceramic bearings (extreme conditions)
Q4: How to adjust bearing preload?
A: Use specialized preload tools: 8-15N for upper bearing, 5-10N for lower bearing (with torque wrench)
Q5: Will lubricant evaporate in UHV?
A: KYKY-VG9 grease maintains vapor pressure below 3×10⁻¹⁰Pa for long-term stability
Q6: How to address abnormal vibration?
A: Recommended steps: ① Spectrum analysis ② Check alignment ③ Adjust preload ④ Replace if necessary
Q7: Can you provide bearing life prediction?
A: Computerized life simulation available based on operational parameters (speed, load, temperature etc.)
Q8: Precautions for bearing removal?
A: Must use proper pullers - no hammering. Check shaft roundness (<0.005mm deviation) after removal
Q9: Storage requirements?
A: Store in controlled environment (20±5℃, RH<40%), clean and free of corrosive gases
Q10: On-site installation support?
A: Available: ① Installation guidance ② Vibration testing ③ Operational commissioning
