An improper installation of imported bearings (about 16%)
Imported bearings during installation using brute force, direct percussion imports bearing the greatest harm to the bearing with a hammer; is the main imports of bearing

deformation .ball bearing

2, imports of bearings installed in place, the installation deviations or mounted to the bearing, 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.angular ball bearings

Recommendation: Select the appropriate professional bearing installation tool, the installation is complete use special detection equipment. On imported bearings installed

correctly, please see the site a text of the introduction of imported bearings are installed correctly describes.precision bearings

Second, imports of poor bearing lubrication (about 50%)

According to the survey, poor lubrication is one of t he main cause premature failure of imported bearings. The main reasons include: not timely lubrication or lubricant;

lubricants or lubricating oil filling is not in place; improper selection of lubricants or lubricants; lubrication method is not correct.

Recommendation: Select the correct lubricant or lubricants, using the correct lubrication filling. On imports of bearing lubrication, you see the site "on imported bearings are

lubricated What is the importance of a text introduced.

Pollution of imported bearings (about 14%)

The pollution can also lead to premature failure of imported bearings. Pollution is dust, metal shavings from entering inside the bearing. The main reasons include: too early to

open the bearing packaging before use, resulting in pollution; installation work environment dirty, polluting; bearing work environment dirty, working medium pollution.

Recommendation: best befor e use Do not disassemble the packaging of imported bearings; to keep the environment clean install, installation and cleaning of the bearings to be

used; enhance the bearing seals.

Imports bearing fatigue (about 34%)
