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

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.
