Hydrogenerator Thrust Bearing

Modified PTFE Thrust Bearing Solution
Advanced Replacement for Babbitt Metal Bearings
▸ Material: Surface-modified PTFE composite
▸ Applications: Hydrogenerators, large motors (custom designs available)

 

Key Advantages vs Babbitt Bearings:
① High wear resistance & low friction – Reduces power loss by up to 30%
② Self-lubricating – Eliminates high-pressure oil lift systems
③ Self-aligning – Equalizes load distribution, prevents hot spots/bearing seizure
④ Maintenance-friendly – No scraping/shimming required
