Product Description
TSTN Guide Bearing
Introducing the TSTN Guide Bearing for Hydro Generators, engineered with advanced self-lubricating, water-lubricated materials to ensure optimal performance and durability.
Key Advantages
Self-Lubricating Material
Utilizing INDRON® 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.
Our Strengths
Our senior material scientists and mechanical engineering specialists have reached the international advanced level in material design, material innovations, material manufacturing and material applications. As a company focusing on the needs of customers and possessing years of experience and professional skills, we are assisting customers in solving their technical problems and providing extraordinary material technology solutions.

Partial data from THORDON product description
Under the same conditions, INDRON® elastoplastic alloy has less wear than other common nonmetal bearing materials, and some of its models are even better than imported materials,which means INDRON® bearing has longer service life, higher reliability and lower maintenance cost.
