What are large diameter bearing used for?

Large diameter bearings are mainly used in the following fields:

• Construction machinery

The main bearing of a shield machine with a diameter of 8.6 meters can withstand huge radial loads and is commonly used in engineering scenarios such as tunnel excavation and large-scale mining equipment. ‌

• Energy equipment

Bearings with a diameter of 8 meters are used in hydroelectric power generation equipment, such as turbine main shaft support systems, which require high load-bearing capacity and anti vibration characteristics. ‌

• Industrial equipment

Bearings for rolling mills with a diameter exceeding 3 meters are used in heavy machinery for steel production lines, which require a balance between high speed and wear resistance. ‌

• EADS

Gyroscope bearings with a diameter of 1.5 meters or more are used in satellite attitude control systems and can operate stably in extreme temperatures (-253 ℃ to 500 ℃) and vacuum environments. ‌

• Special vehicles

Drive shaft bearings with a diameter exceeding 2 meters are used in high load scenarios such as heavy-duty trucks and military vehicles, and can withstand both radial and axial loads simultaneously.
