We choose to import bearings, is for higher speed, accuracy and life

Then why do we buy imported bearings and still get hot?

Causes of bearing heating:

1) reason: low bearing accuracy

Method: select the bearing with specified precision. 

(2) reason: the spindle is bent or the box hole is different

Method: repair the spindle or box. 

(3) reason: the belt is too tight

Method: adjust the belt to make it tight properly. 

(4) reason: poor lubrication

Method: select the specified lubricating material and clean it properly. 

(5) reason: low assembly quality

Methods: to improve the assembly quality. 

(6) reason: the inner shell of the bearing runs laps

Methods: replace the bearing and related worn parts. 

(7) too much axial force

Methods: to clean and adjust the clearance between 0.2 and 0.3mm, correct the impeller balance hole diameter and verify the static balance value. 

(8) bearing damage

Method: replace the bearing. 

In fact, the root cause is to use qualified bearings and correct selection
