Choosing the right bearing has always been on the priority list of producing and 
developing machines. In fact, the right bearings are the ones that ensure smooth and 
safe functioning of any machine while maintaining longevity and functional viability. 
The industrial fans make up an important component of any warehouse or factory, 
cooling the systems down which are susceptible to failure due to heat. In order to 
maintain the life-cycle of these fans, it is important that we choose the right bearings 
for them. Here are some reasons that enunciate the importance of choosing the right 
bearings for industrial fans.
Bearings regulate speed
Some bearings can withstand high speed while some are made for more nominal 
pace. For instance, the presence of a cage for cylindrical roller bearings and needle 
bearings enables greater speed in comparison to those lacking a cage.
Quality industrial bearings take care of the alignment
Misalignment is a common and recurring problem. Choosing the right bearing will 
ensure that the industrial fan is aligned as per its manufacturing guidelines. A 
proper bearing is able to support the misalignment, if any and in case of bearings 
with automatic alignments, they automatically correct the alignment defects as a 
result of installation errors or shaft bending.
Bearings avoid vibration of industrial fans
Vibration in machines may be a result of machine shafts being out of line. The open 
space due to the misalignment causes the shaft to wobble and hence, vibrate. 
Bearings avoid vibration as they clamp down on the shaft and does not allow it to 
move except for its regular & designated movement. Choosing the right bearing is 
important in this case as vibration can also lead to wear and tear as well as early 
abrasion of the fan.
Quality bearings keep foreign elements away from entering the 
machine
In the case of oil bearings, it is very easy for oil to attract foreign elements and 
moisture that can adversely impact the functioning of the industrial fan. However, 
these bearings are also equipped to prevent oil contamination and oxidation. 
Oxidation can cause rusting and oil bearings also help avoid the implication of that.
They improve the fan’s longevity
Need to use the right bearings for the right purpose. In this case of industrial fans, 
the bearings help improve the longevity of the fan and ensure that it performs the 
right function. They also help achieve the purpose of cooling and maintaining an 
optimum temperature of the area.
Conclusion on choosing right bearings for industrial fans
The importance of choosing the right bearing for the industrial fan is non-
negotiable and should be taken into due consideration while looking into 
manufacturing such items.
We can summarize the importance into the following points:
• They regulate speed
• They avoid vibration
• They keep foreign materials in check
• They keep the temperature in check
• They improve the fan’s longevity.
