Improper installation (about 16%)
Installation, use brute force, a direct hit with a hammer bearing on the bearing damage; caused by the deformation of the main reasons for.
Installed in place, the installation of a deviation 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.
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.
Select the correct lubricant or lubricants, use the correct lubrication filling.
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.
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.
