Techemer Water Lubricated Propeller Shaft Bearing
Techemer provides advanced water lubricated propeller shaft bearings designed for modern marine propulsion systems. Based on high-performance elastomeric polymer alloy technology, Techemer PREM bearings deliver low friction, high load capacity, and long service life in demanding seawater environments.
Engineered for both new installations and retrofit projects, Techemer bearings are widely used as a reliable replacement for Thordon COMPAC systems, helping shipowners improve efficiency while reducing maintenance costs.
Why Techemer PREM Bearings?
Techemer PREM is a specially developed elastomeric polymer alloy material optimized for water-lubricated applications in marine, hydro, and industrial systems.
Optimized for Water Lubrication
Ensures stable hydrodynamic film formation, even at low shaft speeds.
Advanced Self-Lubricating Structure
Reduces friction during start-up and mixed lubrication conditions.
High Load Capacity
Performs reliably under heavy shaft loads and misalignment conditions.
Superior Wear Resistance
Extends service life in seawater and abrasive environments.
Oil-Free & Environmentally Friendly
Eliminates oil leakage risks and supports green marine operations.
