What Are Self-Lubricating Bushes?
Self-lubricating bushes (also called bearings or sleeves) are mechanical components designed
to reduce friction between moving parts without the need for external lubrication.
Materials Used
Sintered bronze or iron impregnated with lubricating oil
PTFE (Teflon) composites
Graphite or MoS₂ embedded in metal matrices
Polymer-based materials with embedded lubricants
Use in Hydro Power Plants
Turbine guide vanes
Wicket gate mechanisms
Shaft supports
Water control gates and valves
Key Advantages
Maintenance-free Operation
Ideal for remote or submerged locations.
Corrosion Resistance
Especially important in water-rich environments.
Reduced Downtime
No need for frequent lubrication checks.
Longer Lifespan
Designed to withstand harsh conditions.
