INDRON® TSTN stern tube bushing is a high-performance water-lubricated bearing solution designed for long-term use in marine propulsion systems. Engineered as a durable, non-metallic alternative to Thordon SXL, our bushing offers exceptional wear resistance, low friction under dry-start conditions, and excellent self-lubricating performance, making it ideal for both new vessels and retrofit applications.
Whether you operate a bulk carrier, tugboat, or offshore support vessel, this stern tube bushing delivers reliable shaft support without the need for oil lubrication — helping shipowners cut costs, comply with environmental regulations, and improve system uptime.
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.
Water-Lubricated Operation: Functions under fully submerged conditions — no oil or grease required.
Perfect Replacement for Thordon SXL: Fully compatible in size and performance with industry-standard components.
Long Service Life: Advanced elastoplastic alloy with microcrystalline structure ensures longer lifespan than most composite materials.
Excellent Dry Start Capability: Low friction and high pressure resistance allow safe intermittent lubrication.
High Load Performance: Dynamic bearing surface pressure up to 10 MPa; PV values up to 100 MPa·m/s.
Customizable Designs: Offered in integral, split, slotted, or layered configurations to suit a variety of stern tube systems.
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.
INDRON® Stern Tube Bushings have been successfully installed in bulk carriers, offshore vessels, workboats, and other commercial ships, especially where environmental restrictions prohibit oil-lubricated bearings.
Thanks to their self-lubricating design, these bushings reduce shaft wear and eliminate the risk of lubricant leakage into seawater. This makes them a preferred choice for shipowners replacing Thordon SXL bushings or upgrading older metal or rubber-lined bearings.
Typical use cases:
Stern tube bearings for propulsion shafts
Water-lubricated shaft line systems
Retrofit solutions for greaseless shaft bearing systems
High-load applications requiring dry-start tolerance
