Why Choose INDRON® TSTN Stern Tube Bearing?
When it comes to replacing traditional oil-lubricated or Thordon
SXL water-lubricated stern tube bearings, INDRON® TSTN offers a
robust solution with superior performance and longer lifespan,
designed for modern shipowners who demand reliability and
cost-efficiency.

These performance metrics validate the exceptional durability and
tribological efficiency of INDRON® self lubricated stern tube
bearings, even under continuous operation in seawater environments.
Stern Tube Bearings Key Features & Benefits
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.
Long Service Life: Proven to outlast most non-metallic water-lubricated bearings,
including Thordon SXL, especially in bulk carriers and working
vessels.
Self-Lubricating System: Embedded microcrystals and pressure-resistant lubricating
particles offer dry-start capability and continue to protect under
boundary and starved lubrication.
Low Friction, High Wear Resistance: Balances dynamic loads and abrasive conditions with a low
coefficient of friction, reducing shaft wear and vibration.
High Load Capacity: Supports dynamic surface pressures up to 10 MPa, suitable for
heavy-duty stern shaft systems.
Excellent Water Lubrication Performance: Performs exceptionally in water as a lubricant; PV value up to 100
MPa·m/s, surpassing many competitors in harsh environments.
Environmentally Friendly: 100% grease-free operation minimizes marine pollution and complies
with EAL (Environmentally Acceptable Lubricants) regulatory trends.
