Stern Shaft Bearings
Techemer TSTN Stern Shaft Bearings are engineered to solve the limitations of traditional oil-lubricated and Thordon SXL bearings, offering a longer lifespan, superior water-lubricated performance, and better ROI.
Whether you're upgrading existing vessels or fitting new builds, this is the bearing solution built for the future of marine propulsion.
Techemer Stern Shaft Bearing Key Benefits
Extended Service Life
Proven to last longer than most water-lubricated non-metallic bearings, including Thordon SXL, under identical conditions.
100% Water-Lubricated Operation
No grease, no oil. Performs exceptionally in continuous or intermittent water lubrication.
Dry-Start Capability
Safely supports dry starts — a critical feature for harsh working vessels or emergency scenarios.
Superior Wear Resistance
Techemer TSTN's embedded microcrystals and pressure-resistant particles dramatically reduce wear and shaft damage.
Environmentally Compliant
Meets the increasing global demand for green, oil-free propulsion systems.
