What Makes Techemer TSTN Different?
Techemer 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.
Why Replace Thordon SXL
Thordon SXL has long been used as a standard rudder bearing material. However, modern marine operations place greater demands on service life, dimensional stability, and maintenance efficiency. Shipowners now expect rudder bearings that perform reliably under continuous water lubrication while reducing downtime and lifecycle cost. These practical engineering requirements are driving the shift toward more advanced composite rudder bearing solutions.
Built for modern rudder bearing requirements: Traditional solutions like Thordon SXL no longer meet today's demands for longer wear life, stable water-lubricated performance, and lower maintenance risk. Shipowners now need smarter composite rudder bearings that deliver reliability with reduced lifecycle cost.
Comparable performance, better value: Techemer self-lubricating composite rudder bearings offer wear resistance and friction behavior equal to or better than Thordon SXL, while providing improved cost efficiency over the bearing's service life.
True drop-in replacement: Our rudder bearing matches Thordon SXL dimensions and tolerances. No shaft or housing modification is required, allowing fast installation and shorter dry-docking time.
Designed for real marine conditions: Stable operation in seawater, low-speed oscillation, and high side-load conditions. Reduced edge loading and deformation help extend service intervals.
Lower shaft wear, lower risk: The self-lubricating structure minimizes friction, protects the rudder stock, and reduces unplanned maintenance.
Engineering support included: Material selection, clearance recommendation, and installation guidance—so the rudder bearing performs as expected in service.
