Long Life Span | Water-Lubricated | Stern Shaft Bearing Replacing Thordon SXL

INDRON® TSTN Stern Shaft Bearings are engineered to solve the limitations of traditional oil-lubricated and Thordon SXL bearings, offering a longer lifespan, superior water-lubricated performance, and better ROI.

Whether you're upgrading existing vessels or fitting new builds, this is the bearing solution built for the future of marine propulsion.

INDRON® Stern Shaft Bearing Key Benefits

• Extended Service Life: Proven to last longer than most water-lubricated non-metallic bearings, including Thordon SXL, under identical conditions.

• 100% Water-Lubricated Operation: No grease, no oil. Performs exceptionally in continuous or intermittent water lubrication.

• Dry-Start Capability: Safely supports dry starts — a critical feature for harsh working vessels or emergency scenarios.

• Superior Wear Resistance: INDRON® TSTN’s embedded microcrystals and pressure-resistant particles dramatically reduce wear and shaft damage.

• Environmentally Compliant: Meets the increasing global demand for green, oil-free propulsion systems.

Material Grade & Performances

These performance metrics validate the exceptional durability and tribological efficiency of INDRON® self lubricated stern tube bearings, even under continuous operation in seawater environments.
