Bearings are crucial for industrial centrifugal fans, supporting the fan shaft and minimizing friction. Proper bearing selection ensures efficiency, longevity, and reliability in high-performance ventilation systems.

The Role of Bearings in Centrifugal Fans

Bearings hold the shaft in place as a fan rotates. In overhung applications, they are placed in close proximity to the wheel, placed together on the drive side of the fan housing, supporting the wheel mounted on the end of the shaft. In center-hung applications, one bearing is placed on the drive side and the other is placed on the inlet side of the fan as the wheel rotates on the shaft between the bearings.

Common Types of Fan Bearings Explained

No matter what kind of centrifugal fan you have, you can be sure that it has bearings in its connection to the motor. The bearings enable movement in this heavy-duty industrial machinery. There are two configurations and three common types of fan bearings, which we will outline below.
