Wear Resistance | Water-Lubricated | Stern Shaft bushing Replacing Thordon SXL

INDRON® TSTN Stern Shaft Bushing is a wear-resistant, water-lubricated bearing designed to replace Thordon SXL in marine propulsion systems. Made from a self-lubricating elastoplastic alloy, it offers low friction, dry-start capability, and a longer lifespan, making it ideal for eco-friendly and maintenance-efficient stern tube applications.

INDRON® Stern Tube Bushing Material

Our TSTN stern tube bushings are engineered for consistent performance under tough maritime conditions:

INDRON® TSTN marine rudder bearings are engineered to handle extreme pressure and friction conditions under water-lubricated environments.

INDRON® Stern Shaft Bushing Features

• • • Perfect Thordon SXL Replacement – Directly interchangeable with equivalent sizes, field-tested on commercial ships.

    • High Wear Resistance – Made from TSTN material, engineered for minimal volume loss under dry or fluid-lubricated conditions.

    • Water-Lubricated & Grease-Free – Environmentally compliant solution that eliminates oil leakage risks.

    • Dry Start Compatible – Stable performance during intermittent lubrication or start-up phases.

    • Low Friction Operation – Ensures smooth shaft rotation and reduces wear on both shaft and bearing.

    • Supports High Loads – Handles dynamic pressures up to 10 MPa, suitable for demanding propulsion environments.

    • Custom Configurations – Available in integral, split, or segmental types to fit various stern tube housings.

Products Show

The INDRON® TSTN stern tube bearing is widely used in bulk carriers, tugboats, working vessels, and ocean energy systems. As a direct Thordon SXL alternative, it operates under harsh seawater conditions with minimal maintenance and long-lasting performance. Its proven durability and self-lubricating water-lubricated structure significantly reduce operational costs for shipowners, while enhancing rudder and stern tube reliability.
