ENSURE ASSET RELIABILITY IN DEMANDING ENVIRONMENTS
For Naval applications, bearing reliability is essential to maintaining vessel availability. Proven in naval applications, Thordon Bearings’ COMPAC seawater-lubricated propeller shaft bearing system offers dependable performance, long wear life and practical operational benefits. COMPAC is a self-lubricating elastomeric polymer bearing material that provides impact and shock resistance, supporting reliable performance in challenging operating environments. Its design establishes a stable hydrodynamic film at lower shaft RPMs than other water-lubricated materials, supporting smooth, low-friction operation. Its operating characteristics also contribute to a low acoustic signature, an important consideration for Naval vessels.
REDUCE MAINTENANCE AND DOWNTIME
For Naval and Coast Guard vessels, propulsion reliability is critical to operational readiness. Minimizing maintenance, downtime and drydocking frequency can help keep vessels in service when they are needed most. COMPAC’s split bearing and tapered key design allow the bearing to be removed for inspection or replacement without removing the shaft or bearing carrier, reducing renewal time and minimizing disruption to vessel operations.
SECURE A COMPLETE SHAFTLINE SOLUTION
The COMPAC system combines the propeller shaft bearing with technologies that support performance, monitoring and survivability. The Water Quality Package conditions the water supplied to the bearings and seal, while the Bearing Condition Monitoring System provides remote, real-time bearing clearance information. ThorShield Shaft Coating protects the shaft, and the SeaThigor mechanical face seal provides a robust, maintenance-free sealing solution with Safe Return to Port capability. If the seal faces are damaged, this capability allows the shaft to continue turning, supporting vessel survivability and operational continuity.
Together, these technologies provide a complete shaftline system designed around the operational requirements of Naval and Coast Guard vessels. Today, more than 50 Navies and Coast Guards worldwide trust Thordon’s COMPAC seawater-lubricated bearing solution, bringing extensive experience to Naval propulsion applications.
For Naval operators looking to improve propulsion reliability, extend bearing service life, reduce maintenance demands and minimize docking frequency, COMPAC is a proven solution.
