INDRON® water lubricated stern tube bearings are engineered to meet the rigorous demands of modern marine propulsion systems. Extensively applied in stern tube and rudder bearing systems on bulk carriers and working vessels, INDRON® self-lubricating bushings have proven their durability and efficiency in harsh marine environments.

These performance metrics validate the exceptional durability and tribological efficiency of INDRON® water lubricated stern tube bearings, even under continuous operation in seawater environments.
Compared to other non-metallic options in water-lubricated bearing systems, INDRON® stern tube bearings exhibit significantly enhanced wear resistance, mechanical strength, and dimensional stability under water pressure and dynamic loads. These advantages translate into:
Longer bearing lifespan
Reduced shaft wear
Minimized maintenance downtime
Lower total cost of ownership
INDRON® materials have been carefully developed to optimize tribological performance in water-lubricated environments, making them an ideal solution for both stern tube bearings and marine rudder bearings.
Our company will take integrity, quality first, customer first and first-class service as its tenet.
