As a spherical roller bearing manufacturer, sometimes we heard voice about bearings damage problem. WXMK engineers summed up some mainly reasons of bearing damage to show to spherical roller bearings distributors and end users.
Whether the bearing runs well or not directly affects the normal operation of mechanical equipment. In the use of spherical roller bearings, what factors caused the damage of spherical roller bearings? The following four aspects are analyzed.
1) Improper installation
1- Hammer the bearings by hammer and use brute force when install the bearings, this is the worst way to damage the bearings, it is the main reason to made the bearings became deformed.
2- Installation is not in the right place, installation deviation or not installed in the bearing position, resulting in too small bearing clearance. The inner ring and outer rings are not in the same revolving center, resulting in different concentric.
Suggestion&Solution:
Select appropriate or professional bearing installation tools, inspection is needed by the special instruments after completed installation.
2) Bad lubrication
According to the survey, bad lubrication is one of the season to resulting in the bearing damage. The main reasons including: not fill the lubricant in time, lubricant was not filled in the right place, select the wrong lubricant, incorrect lubrication, etc.
Suggestion&Solution: select the right lubricant or fill the lubricant in a correct way
3) Fatigue
Fatigue damage is a common way of bearing damage. Common causes of fatigue damage may be: Bearing long-term overload operation; not timely maintenance; improper maintenance; equipment aging, etc.
Suggestion&Solution: Choose the appropriate bearing type and replace the fatigue bearing regularly and timely.
4) Pollution
Pollution result in the earlier damage to the bearings, pollution refers to the entry of dust, metal chips, etc. into the interior of bearings. The main reasons including: premature opening of bearing package before use, causing pollution. Unclean working environment during installation, causing pollution; unclean working environment of bearing, polluting working medium, etc.
Suggestion&Solution: It's better not to dismantle the packaging of bearings before use. Keep the installation environment clean during installation, clean the bearings and enhance the sealing device of the bearings.
We can see that the correct operation method can greatly reduce the bearing damage. Meanwhile, we should pay attention to the usual maintenance, only in this way we shall create a good working environment for use later.
