Techemer - Water-Lubricated Bearings & Shaft Seals Manufacturer Since 2008
Marine Bearings
Marine Bearings are critical components in ship propulsion systems, supporting propeller shafts, rudder shafts, and stern tube assemblies. These bearings must operate reliably under heavy loads, seawater exposure, and continuous rotation while maintaining low friction and long service life.
Techemer marine bearings use advanced water-lubricated composite materials to provide excellent wear resistance, corrosion protection, and stable shaft support in harsh marine environments. Compared with traditional oil-lubricated systems, they reduce maintenance requirements and help improve propulsion efficiency for modern vessels.

Techemer's TSTN water-lubricated composite bearing material is engineered for demanding pump and marine applications and serves as a high-performance alternative to Thordon SXL. Carefully formulated with self-lubricating microcrystals and extreme pressure particles, TSTN offers low friction, high wear resistance, and reliable dry-start performance. Its PV capability of up to 100 MPa·m/s under water lubrication and resistance to adhesive wear make it ideal for critical guide bearings, thrust bearings, and bushings in heavy-duty environments.
Techemer water-lubricated marine rudder and stern tube bearings engineered to replace Thordon bushings. Superior wear resistance, long service life and reliable performance for modern vessels.
Techemer water-lubricated stern tube bearings are ISO certified and engineered to deliver an extended service life and reliable performance in marine stern tube applications. Designed as equivalent replacements for Thordon bushings, these water-lubricated bearings exhibit superior wear and corrosion resistance, high load capacity, and low maintenance requirements, supporting cleaner vessel operation and longer maintenance intervals.
Techemer self-lubricating fore & stern tube marine bearings are engineered with an advanced elastomeric polymer alloy, providing superior wear resistance, low friction, and long service life under water-lubricated conditions. Designed to replace traditional Thordon SXL stern tube and rudder bearings, they offer environmental benefits, dry start capability, and reduced maintenance — making them ideal for bulk carriers, working vessels, yachts and deck machinery.

Why Is Marine Bearings Important
In marine environments, bearings face extreme stress, constant exposure to seawater, and continuous vibration. Key roles include:
- Marine shaft bearings: stabilizing the propeller shaft, reducing friction and wear.
- Marine thrust bearings: handling axial loads from propellers and engines.
- Marine rudder bearings: ensuring smooth steering under heavy loads.
- Marine bearing seals: preventing leakage and keeping systems efficient.
If your vessel struggles with frequent bearing replacements or oil leakage, it’s time to switch to a better solution.
