Guide bearings are critical components in hydro turbine systems. They are designed to support and guide rotating or oscillating shafts, guide vanes, and related mechanisms, ensuring smooth movement, reduced friction, and long-term operational stability. In real hydro power applications, the performance of guide bearings directly affects turbine efficiency, maintenance frequency, and overall service life.
Techemer's UNIV and TSTN composite guide bearings are engineered as modern replacements for traditional metal or oil-lubricated bearings. They are widely used as guide vane sleeves and shaft guide bearings in turbines, delivering reliable performance in demanding hydro power environments.
What Is a Guide Bearing?
A guide bearing (sometimes referred to as a guided bearing) is used to control shaft or guide vane movement by providing radial support and precise alignment. Unlike thrust bearings, which carry axial loads, guide bearings mainly stabilize motion and reduce vibration during operation.
In hydro turbines, guide bearings are commonly installed as:
Guide vane bearings
Shaft guide bearings
Guide vane sleeve bearings
These components operate continuously in wet environments, making material selection and bearing design especially important.
Why Composite Guide Bearings Are the Industry Choice
Traditional bronze or metal guide bearings often suffer from corrosion, high wear rates, and dependence on oil lubrication. Composite guide bearings solve these problems through advanced polymer materials and self-lubricating technology.
Key advantages include:
Self-lubricating performance
No external oil or grease required
Low friction coefficient
Smooth operation under variable loads
Excellent wear resistance
Stable performance over long service life
Corrosion resistance
Ideal for water-lubricated environments
Environmentally friendly
No risk of oil leakage
These benefits make composite guide bearings especially suitable for hydro turbines, pumped storage units, and renewable energy systems.

Guide Bearing and Thrust Bearing: How They Work Together
In a complete hydro bearing system, the guide bearing and thrust bearing perform different but complementary roles.
Guide bearings control radial movement and maintain shaft alignment
Thrust bearings absorb axial loads generated by water pressure and turbine forces
Using properly matched guide and thrust bearings helps reduce uneven wear, improve system stability, and extend the service life of critical turbine components.

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.
Typical Applications of Guide Bearings
Techemer composite guide bearings are widely used across hydro power and water-lubricated industrial applications.
- Kaplan and Francis Turbines
Guide bearings in Kaplan and Francis turbines must withstand frequent guide vane movement and fluctuating loads.
- Vertical Hydro Generator Units
Shaft guide bearings play a key role in stabilizing vertical generator shafts during continuous operation.
- Pumped Storage and Small Hydro Plants
Composite guide bearings are ideal for pumped storage and small hydro installations due to their durability and low maintenance requirements.
