Gas and Steam Turbine Bearings for Thrust and Journal Use

History of Modern Gas and Steam Turbine Bearing Development

In the early s, gas turbine bearing and steam turbine applications began pushing the safe operating limits of flooded tilting pad hydrodynamic bearings. Shaft speeds and loads had increased to the point that bearing surface temperatures and associated power losses were of concern in the design of larger, faster, more efficient turbines.

In response to the demands of our market, Kingsbury developed the Leading Edge Groove (LEG®) lubrication technology for both thrust and journal bearing applications. This design provides superior bearing performance while simultaneously reducing oil flow requirements, which translates into higher turbine efficiency.

With competitive price and timely delivery, Hangzhou Journal Bearing sincerely hope to be your supplier and partner.

• Reduces operating temperatures by 5° to 20° C, depending on shaft speed
• Increases load capacity by 15% - 20%, reducing required bearing size
• Lowers oil flow by 50%, allowing for reduced lube system demand
• Improves efficiency, with a 45% reduction in friction losses

The applications and data demonstrate that LEG® technology is a cost effective and reliable method of lubrication that improves efficiency, lowers capital costs, and adds value to machinery.

Enter the BPG® Journal bearing for even greater machine efficiency

More recently, a new addition has joined the directed-lubrication family of Kingsbury journal bearings, the Between Pad Grooves (BPG®), improving machine performance even more:

• BPG® journal bearings direct lubrication using feed bars between pads to introduce cool oil
• BPG's lower oil flow rate results in significantly reduced power losses
• Unlike the LEG® bearing, BPG® can be designed for bi-directional shaft rotation when required
