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.
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.
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.
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.
We have documented dozens of successful installations of INDRON® TSTN stern shaft bushings in real-world applications. These include both OEM integration and retrofit projects across Asia, Europe, and North America.
Our company will take integrity, quality first, customer first and first-class service as its tenet.
