Long Life Span | Self-Lubricating | Stern Tube bearing Replacing Thordon SXL

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.
