Water-Lubricated Bearing

Water-Lubricated PTFE Bearing Solution
Optimized for Hydro/Wet Environments
▸ Material Composition: PTFE-based matrix with water-adaptive additives
▸ Applications: Hydropower units, marine systems, pumps (custom designs available)

 

Key Performance Advantages:
Low friction & high wear resistance – Reduced energy loss, extended service life
Hydro-stable – Minimal water absorption (<0.5%), maintained dimensional accuracy
Particle embeddability – Protects shafts from contaminant damage
Corrosion-proof – Withstands acidic/alkaline water, prolongs bearing lifespan
Vibration damping – Enhances rotational stability (e.g., reduces shaft runout)
