Water Lubricated Stern Tube Bearings Equivalent To Thordon Bushing ISO Certified Long Lifespan

Please see our ISO certified water-lubricated stern tube bearings designed for reliable shaft support in marine propulsion systems. These precision-engineered bearings, equivalent to Thordon bushings, deliver long service life, superior wear resistance and environmentally friendly water lubrication for commercial vessels, workboats and yachts.

At Techemer, we've specialized in the R&D and manufacturing of water lubricated bearings and shaft seals since 2008. With a team of expert material scientists and marine engineers, we focus on developing high-performance solutions for critical marine systems.

• Reliable water lubrication for stern tube systems: Techemer water-lubricated stern tube bearings are ISO certified and engineered to match the performance of Thordon bushings while delivering a significantly longer service life in marine propulsion environments.
• Superior wear and corrosion resistance: Made from advanced elastomeric polymer alloys with embedded self-lubricating properties, these bearings reduce shaft wear, improve load capacity, and provide low friction operation in seawater-lubricated conditions.
• Low maintenance, environmentally friendly design: With oil-free water lubrication, these bearings eliminate leakage risks, reduce maintenance needs, and support cleaner, more sustainable vessel operation — ideal for commercial vessels, working ships and yachts.
