INA bearings early damage caused for several reasons

First, the poor lubrication (about 50%)
According to the survey, poor lubrication is one of the main causes of premature bearings damage. Major causes include: no lubrication or lubricant in a timely manner; lubricant or lubricant does not raise in place; selection of lubricants or lubricant improper; incorrect lubrication method, and so on.
Recommendation: choose the right lubricant or lubricant, using correct notation of lubrication method.
Second, improper installation (about 16%)
1, when installed using brute force, directly with a hammer hammering INA bearings to bearings damage the largest are the main cause of deformation.
2, the installation is not in place, install a biased or not loaded to bearings, resulting in bearings clearance is too small. Inner and outer rings will not be in the same center of rotation, resulting in different heart.
Recommendation: select the appropriate bearings installation tool or professional, installed using special instruments and testing.
Three, fatigue (about 34%)
Fatigue failure is a common damaged bearings ways. Common causes of fatigue may be: long-term overload operation of bearings; not timely maintenance; improper maintenance; aging equipment, and so on.
Four, pollution (about 14%)
Pollution can also cause premature damage of INA bearings, pollution refers to sand, scrap metal into the bearings. Major causes include: prematurely opened INA bearings package before using, causing pollution; installation work environment hygiene pollution; bearings working environment is clean, actuating medium pollution.
Recommendation: before use it is best not to open the bearings package; installation keep the environment to install clean, clean bearings to be used; enhanced bearings sealing device.
Summary of reasons for early damage of the INA bearings hope after we should pay attention to.

Next: SKF bearings checking and acceptance should pay attention to what issues
