Introducing the TSTN Guide Bearing for Hydro Generators, engineered with advanced self-lubricating, water-lubricated materials to ensure optimal performance and durability.
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.

Under identical conditions, INDRON® elastoplastic alloy exhibits less wear compared to other common non-metal bearing materials. Some models even surpass imported materials, translating to longer service life, higher reliability, and reduced maintenance costs.
INDRON® guide bearing is performance comparable to Thordon; compatible with various assembly methods, including traditional installations by freezing and pressurizing, as well as reactive thermal polymerization Dx and cold sticking. Can use clean water for lubrication or withstand 150s dry start, depending on material grades.
