A, improper installation, (about 16%)
1, when installed using brute force, directly with a hammer hammering TIMKEN bearing to bearing damage the largest are the main cause of deformation.
2, the installation is not in place, install a biased or not loaded to bearing, resulting in bearing 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 bearing installation tool or professional, installed using special instruments and testing.
Second, the poor lubrication (about 50%)
According to the survey, poor lubrication is one of the major causes of premature damage of TIMKEN bearings. 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.
Three, pollution (about 14%)
Pollution can also cause premature damage of TIMKEN bearings, pollution refers to sand, scrap metal into the bearing. Major causes include: open bearing prematurely before using packaging, resulting in pollution; installation work environment hygiene pollution; bearing's working environment is clean, actuating medium pollution.
Recommendation: before use it is best not to open the bearing package; installation keep the environment to install clean, clean bearings to be used; enhanced bearing sealing device.
Four, fatigue (about 34%)
Fatigue failure is common TIMKEN bearing damage. Common causes of fatigue may be: long-term overload operation of bearings; not timely maintenance; improper maintenance; aging equipment, and so on.
Suggestion: choosing a suitable type of bearing, regular and timely replacement of bearing fatigue.
