Gas Turbine Bearings

Gas Turbine Bearings

  • Supports the rotating shaft.
  • Reduces friction and allows smooth rotation.
  • Essential to minimize wear and ensure efficiency.
  • Designed to bear high temperatures and load in the turbine.
  • Maintains shaft alignment for optimal performance.


Gas turbine bearings are the supportive pillars that allow shafts to rotate smoothly. It plays a crucial role in the turbines’ smooth operation and performance. Gas turbine bearings are positioned along the length of the turbine shaft to allow it to rotate smoothly without friction. Primarily, they are designed to reduce friction between the turbine’s moving parts, particularly between the shaft and casing. Otherwise, it results in energy losses and slows the turbine’s rotation.

Additionally, foil bearings gas turbines are used to reduce friction through air spaces or greases to ensure smooth performance. Moreover, bearings are designed to withstand extreme forces generated by the high-speed rotation of the shaft and thrust of blades. They evenly distribute the load to prevent excessive wear and damage to the components. For this reason, proper alignment of the turbine shaft is essential for reliable operation, and bearings must maintain proper alignment. This alignment prevents issues such as uneven wear on the turbine blades or damage to other components, prolonging the turbine’s lifespan and reducing maintenance requirements.

Furthermore, they are manufactured to bear the temperatures, pressure, and constant rotation. Bearings are made up of high-performance materials and often utilize lubrication systems to withstand these harsh conditions and minimize wear. In this way, turbine bearings provide essential support, reduce friction, handle loads, and maintain alignment, all of which are vital for the smooth and efficient operation of the turbine. They ensure that the turbine can generate power reliably and effectively.
