An Essential Guide to Industrial Fan Bearings

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.

Industrial Fan Balancing

What is a Balanced Fan? Think “Finishing the Job.”

A balanced fan must stay below specific vibration limits for safe operation while running at full speed. Excessive vibration will decrease the life of your fan and can lead to catastrophic failure.

How to Clean a Blower Wheel

3 Ways to Clear Debris from an Industrial Fan

Sometimes the most simple things like cleaning get overlooked, potentially leading to many more serious issues. It’s important to properly clean a blower wheel, as material buildup on a wheel can cause vibration and damage your fan. Even “clean air” may contain various particles and debris. A simple cleaning procedure can keep your fan healthy and decrease downtime.

Horizontal Split Housings: Easy Access for Maintenance

Centrifugal fans, with their moving parts and sometimes heavy-duty air processing, require regular fan maintenance in industrial applications. You might need to clean it, you might need to balance it, you might need to repair a part, or even retrofit the fan. At some point, you’ll need access to work on the wheel and shaft. If you’re not sure you’ll be able to get into the access doors in your application, split housings might just save the day.

Lubricant Additives & Their Functions

Bearing life is a major component in overall fan life. Maintaining proper lubricant levels with appropriate lubricant for the application will extend bearing life and require fewer replacements. A simple preventative maintenance program implemented for your fan can save thousands of dollars in replacement parts over the course of several years. Such a plan would involve such steps as regular lubrication of fan and motor bearings, connection inspections, and vibration analyses.
