Long Life Span | Water-Lubricated | Rudder Bearing Replacing Thordon SXL

INDRON® TSTN water-lubricated rudder bearing is a high-performance, long-life marine bearing designed to replace Thordon SXL. Developed with advanced elastoplastic alloy and embedded microcrystalline self-lubricating particles, this bearing excels under harsh marine conditions where durability, low friction, and minimal maintenance are critical. INDRON® TSTN is widely recognized as a cost-effective, eco-friendly alternative to conventional oil-lubricated metal bearings.

INDRON® Rudder Bearings Material

Whether you're dealing with retrofit or newbuild, INDRON® TSTN bearings can be customized to match Thordon SXL dimensions with ease.

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

INDRON® Rudder Bearing Features

• Exceptional Wear Resistance: Engineered with long-lasting self-lubricating particles, INDRON® TSTN offers a significantly longer service life compared to other non-metallic rudder bearings.

• Water-Lubricated & Eco-Friendly: Operates entirely without oil or grease, making it suitable for environmentally sensitive marine zones.

• Thordon SXL Replacement: Proven to replace Thordon SXL with better cost efficiency and comparable or superior mechanical performance.

• Dry Start Capability: Enables reliable operation even under intermittent or dry conditions, thanks to bonded extreme pressure microcrystals.

• Low Friction Operation: Reduces shaft wear and improves operational efficiency.

• Dynamic Load Capacity: Withstands integral dynamic bearing surface pressure up to 10 MPa.

• Versatile Form Factor: Available in integrated, split, or slat-type bushings to meet diverse vessel and rudder system designs.

The INDRON® TSTN water-lubricated rudder 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.

What Makes INDRON® TSTN Different?

INDRON® TSTN is a next-generation elastoplastic bearing material, developed with:

• Long-life self-lubricating particles

• Extreme-pressure resistance

• Balanced low friction and durability

• Minimal volumetric wear in wet and dry conditions

This formulation makes it ideal for rudder bearings subjected to high-impact steering loads and corrosive seawater environments.
