Provides exclusive upper and lower bearing solutions for KYKY FF100/150 grease-lubricated turbo molecular vacuum pumps. This article details product technical parameters, core advantages, and practical case studies, along with answers to 10 common questions, helping you solve equipment maintenance challenges and improve operational efficiency.
The KYKY FF100/150 series, as a representative model of laboratory and industrial molecular pumps, operates in high-speed and ultra-high vacuum environments.
Our OEM-grade adapted bearings offer three major technical upgrades:
✅ Anti-Centrifugal Deformation Design: Double-row angular contact ball bearing structure ensures stable operation at 30,000 RPM
✅ Nano-Lubricant Grease: Uses perfluoropolyether (PFPE)-based grease, supporting operation from -80°C to 300°C
✅ Vacuum Compatibility Certification: Passes ASTM E493 ultra-high vacuum testing with a leakage rate < 1×10⁻¹¹ Pa·m³/s
✅ Modular Quick Replacement: Patent-fixed ring design reduces replacement time to under 2 hours

· Customer Pain Point: A wafer factory's FF150 pump frequently jammed, with single repair costs exceeding ¥20,000
· Solution: Replaced with silicon carbide ceramic balls + titanium alloy cage bearings, paired with perfluoropolyether lubricant
· Verification Results:
▶ Equipment MTBF (Mean Time Between Failures) increased from 120 days to 380 days
▶ Annual maintenance cost savings of ¥680,000
▶ Etching uniformity improved by ≥15%
· Operating Requirements: Continuous operation at liquid nitrogen temperature (-196°C) for 72 hours
· Custom Solution:
● Low thermal expansion coefficient silicon nitride ceramic balls
● Fluorosilicone low-temperature lubricant
· Test Data:
▶ Low-temperature startup peak torque < 0.5N·m
▶ Extreme temperature difference maintained radial runout ≤ 0.005mm
A: Check if the axial preload force exceeds 30kgf and whether the lubricant has hardened or stratified (recommended to replace with PFPE-based grease)
A: Possible due to fit clearance > ISO 4 grade tolerance, requiring re-polishing of the mounting surface to Ra0.4μm
A: For continuous operation ≥8 hours/day, replenish grease every 6 months (2g); for <4 hours/day, maintain every 12 months
A: We offer a fast service channel, with on-site arrival within 2 hours in the Pearl River Delta region and nationwide solutions within 72 hours
A: Contaminant residues can increase initial wear of new bearings by 3-5 times; ultrasonic cleaning + vacuum drying is recommended
A: Compliant with ASTM E493 standards, ceramic coating layers can withstand 1×10⁻¹⁰Pa vacuum
A: Thermal expansion coefficient differences >50% can cause stress concentration; preload compensation is recommended
A: Standard parts inventory available in 7 days, special specifications take <30 days (priority processing with 3D data provided)
A: Compatible with over 95% of FF100/150 series versions; specific model parameters are required
A: Provides NFC electronic tag chips, recording replacement batches, operating conditions, and full lifecycle data

Preventive Lubrication Strategy
2.
· Use temperature-indicating lubricant with color change (color change range 50-200°C)
· Stacked lubrication system design (primary lubrication + emergency backup)
3.
Fault Prediction Technology
4.
· Vibration spectrum analysis to identify rolling element wear (>500μm/min requires attention)
· Shaft current monitoring to warn of electro-corrosion damage
