TSTN Guide Bearing
TSTN Water-Lubricated Guide Bearing is designed for hydro generators and water-lubricated turbine systems, providing stable radial support without oil or grease.
Made from self-lubricating TSTN composite material, the bearing delivers low friction, high wear resistance, and long service life. It can operate safely during start-up or temporary water shortage, with no need for pre-water injection, effectively protecting both shaft and bearing surfaces.
Compared with traditional rubber and non-metal bearings, Techemer TSTN guide bearings offer better durability, higher load capacity, and reduced maintenance, making them a reliable and cost-effective solution for modern hydropower applications.
Key Advantages
Self-Lubricating Material
Utilizing Techemer TSTN elastic-plastic alloy integrated with long-term lubricative particles, our bearings offer exceptional self-lubrication and water lubrication properties. This design effectively reduces starting torques, a common issue with traditional rubber turbine guide bearings, thereby protecting the shaft and bearing bushing.
No Pre-Start Water Injection Required
Our bearings eliminate the need for water injection before startup, allowing for transient operations without water or during water shortages, enhancing operational flexibility.
Consistent Performance
The excellent lubricating properties against friction ensure optimal operating clearances over extended periods, maintaining efficiency and reliability.
Products Show
Techemer TSTN guide bearings are widely used in hydro generators and hydro turbine systems to support rotating shafts and maintain precise alignment under continuous water lubrication. The advanced composite material combines low friction with excellent wear resistance, ensuring stable operation in large hydropower units.
With high load capacity and reliable self-lubricating performance, Techemer water lubricated guide bearings are ideal for hydro turbines, vertical pumps, and other heavy-duty water-driven equipment requiring long service life and low maintenance.

Partial data from THORDON product description
Under the same conditions, Techemer elastoplastic alloy has less wear than other common nonmetal bearing materials, and some of its models are even better than imported materials,which means Techemer bearing has longer service life, higher reliability and lower maintenance cost.
Our Strengths
- Advanced self-lubricating composite design for reliable hydro performance: Techemer TSTN guide bearings use a high-performance elastoplastic alloy integrated with long-term lubricative particles, offering exceptional self-lubrication and water lubrication without the need for continuous lubrication or pre-start water injection. This significantly protects shaft and bearing life.
- Enhanced operational flexibility and durability: No water injection is required before start-up, allowing safe transient operations even during brief water shortages. Low friction and consistent performance help maintain optimal clearances over extended periods, improving reliability under real hydropower conditions.
- Superior wear resistance and reduced maintenance: Compared with traditional rubber or other non-metal materials, the TSTN material exhibits less wear and higher dynamic load capacity, which extends service life, reduces downtime, and lowers overall maintenance costs for hydro generator systems.
