Some time ago friend's reaction the bearing damaged very early, so he suspected counterfeit. After analysis turned out to be their own problems. Then the resulting concrete bearing the causes of damage early on, what is it? Now I will give you answers.
Improper installation (about 16%)
1, when installed using brute force, a direct hit with a hammer bearing on the bearing damage; cause deformation of the main reason.
2, the installation is not in place, the installation of a biased or not attached to the bearing bit, causing the bearing clearance is too small. Inside and outside the ring is not in the same center of rotation, resulting in a different heart.
Recommendation: Select the appropriate or professional bearing installation tool installed to use special equipment testing.
Second, poor lubrication (about 50%)
According to the survey, poor lubrication is one of the main reasons that cause premature bearing damage. Mainly due to: and not timely filling of lubricants or lubricants; lubricants or lubricants are not filling in place; improper selection of lubricants or lubricants; lubrication incorrect.
Recommendation: Choose the correct lubricant or lubricants, use the correct lubrication filling.
Third, pollution (about 14%)
Pollution can lead to premature bearing damage, pollution, dust, metal shavings from entering inside the bearing. The main reasons include: bearing packaging prior to use to open prematurely, causing pollution; installation dirty work environment, causing pollution; bearing the dirty work environment, the pollution of the working medium.
Recommendation: best before use packaging; Do not disassemble bearings keep the environment clean install, install bearing cleaning; enhanced bearing the seal device.
Fourth, fatigue (about 34%)
Fatigue failure is bearing a common way of damage. Common fatigue failure may be due to: the bearings long-term overload operation; maintenance is not timely; improper maintenance; equipment aging.
Recommendation: Select the appropriate type of bearing, regular and timely replacement of fatigue bearing.
The above is the most common cause of several reasons for early bearing damage; bearing early damage for many reasons, the above is the main consideration, it may sometimes be comprehensive reasons. Bearing selection is correct, install correctly in place, correct lubrication method and lubricant selection can work very often the time of the bearing.
