First, improper installation (about 16%)
1, the installation of brute force, with a hammer directly hit the bearing, the largest damage to the bearing, is the main cause of deformation.
2, the installation is not in place, the installation is biased or not loaded into the bearing, resulting in small clearance bearing. The inner and outer rings are not in the same rotating center, causing different hearts.
Recommendation: choose the proper or professional tool for the installation of bearings. The installation shall be done with special instruments.
Two, poor lubrication (about 50%)
According to the survey, poor lubrication is one of the major causes of premature damage to bearings. The main reasons include: not timely filling lubricants or lubricants; lubricants or lubricants are not in place; lubricants or lubricants improper selection; lubrication is not correct, and so on.
Tip: choose the right lubricant or lubricant and use the correct lubrication method.
Three, pollution (about 14%)
Pollution can also lead to premature damage to bearings, pollution means sand, metal debris, etc., into the bearing. The main reasons include the premature opening of the bearing package, the pollution, the unclean working environment during the installation, the pollution of the working environment of the bearing, the pollution of the working medium, etc..
Suggestion: it is better not to open the packing of the bearing before use; to keep the installation environment clean during the installation; to clean the bearings to be used; to strengthen the sealing device of the bearing.
Four, fatigue (about 34%)
Fatigue damage is a common damage to bearings. Common causes of fatigue damage may be: long-term overload operation of bearings; not timely maintenance; improper maintenance; aging equipment.
