产品信息

Gas turbines bearings are often subjected to high loads, high speeds and high temperatures, especially as capacity and efficiency demands increase.

To ensure optimum dynamic characteristics in specific operating conditions, BHS Bearings applies a variety of specialized design features to bearing solutions.

For medium turbines used plain journal bearing. They may be ring lubricated sleeve bearings with bronze or Babbitt lining. Both flooded and force types are employed.

For larger turbines, the radial bearing will be a tilting pad type. The number of pad per bearing will be selected based on the weight of the rotor. For these types of bearing forced lubrication is used.

The thrust bearing is located on the free end of the rotor or we can say at the steam inlet of the turbine. The axial thrust force is very small for impulse turbines. This is due to the presence of pressure equalizing holes in the rotor discs to balance the thrust force generated across the disc. A simple thrust bearing such as a radial babbitt facing on journal bearings are commonly used in small and medium-size turbines. Tilling pad type thrust bearings are used in the large gas turbines.

We provided journal bearing for gas turbine power from 5MW-1000MW
