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
