Bronze bushings for Hydroelectric

According to the hydropower station, the use of natural water flow and regulation capacity can be divided into two categories.

  • Run-of-River Hydropower Station: no reservoir or very small reservoir capacity, no or very little regulation of natural water flow.
  • Storage Type Hydropower Station: reservoirs with a certain capacity, with different regulating abilities for natural water flow.
  • Our aluminum bronze sealing rings are professionally used in pumped storage hydropower stations, with material CuAl10Fe3, high strength, wear resistance, and corrosion resistance.
  • We have the ability to produce products φ 1.5m-6m, the only manufacturer you can find for super large-size bronze bushings!

It is really difficult, and we have gone through hundreds of debugging and experiments to conclude the successful experience. At present, the one-time casting success rate of 1.5m to 3.5m diameter is 100%, and the success rate of 3.5m to 5m is 85%.

Are your bushings a complete replacement for bearings?

Yes, they can. For different industries and site environments, we produce products with different hardness, strength, corrosion and wear resistance characteristics. We also have bimetallic bearings to save cost and ensure quality at the same time.

How long does it take to produce?

Sealing rings for the hydropower industry are very special because of their large size and are basically not in stock. The typical time from material to delivery is 15-60 working days.

How do you do quality inspection for such a large product?

We have inspection process: raw materials, smelting formula, spectral test, CMM dimensional inspection, PT/UT inspection, factory inspection. You can control every step.

Service Products

We have a large selection of plain bearings for various applications. With us you can order your products according to your own drawings and specifications or you can choose from our large and wide standard selection.
