INA bearing four common possible causes of damage

A, improper installation
　　1, the installation using brute force, tapping INA bearing directly on the bearing with a hammer hurt the largest is a major cause deformation.
　　2, the installation is not in place, install a biased or not loaded to INA bearings, resulting in bearing clearance is too small. Inner and outer rings are not in the same center of rotation, resulting in different hearts.
　　Recommendation: choose the proper bearing installation tool or professional, installation to be detected by special instruments.
B poor lubrication
　 According to the survey, poor lubrication is one of the major causes of premature failure of bearings. Main reasons for include: no lubrication or lubricant in a timely manner; lubricants or lubricant unraised; lubricants or lubricant improper selection; lubrication method is not correct, and so on.

Pollution can also lead to premature bearing damage, pollution refers to activities such as sand, metal shavings into the bearing. Main reasons for include: prematurely opened INA bearing package before use, pollution; installation, clean working environment, pollution; bearings work environment hygiene actuating medium pollution.
　　Recommendation: before use, it is best not to open the bearing package; installation maintain a clean installation environment, to be used to wash the bearing building bearing sealing device.
D, fatigue
Fatigue is a common form of damage of the bearings. Common causes of fatigue may be: long-term overload operation of bearings; failing to repair; repair improperly; ageing of the equipment.
　　Recommendation: choose the appropriate type of bearing, and timely replacement of bearing fatigue on a regular basis.
　　INA bearing caused several of the above are the most common reasons for early damage; bearing early damage was caused by many, are key reasons above, sometimes synthesis may be the cause. If the correct selection of bearing installation in place correctly, correct lubrication and lubricant selection, bearing works very often.
