Special attention should be paid to these four problems when using precision single row roller bearing:
I. Pollution
Pollution will lead to premature damage of precision single row roller bearing; Pollution mainly refers to dust, metal chips and so on into the bearing interior. The main reasons include: open the stainless steel bearing package prematurely before use, causing pollution; Installation of the working environment is not clean, resulting in pollution.
Suggestion: it is best not to open the packaging of precision single row roller bearing before use; Keep the installation environment clean when installing. 
Two, poor lubrication
According to the investigation, poor lubrication is one of the main reasons for premature damage of precision single row roller bearing. The main reasons include: not filling lubricant or lubricating oil in time; The lubrication is not correct and so on.
Suggestion: choose the right lubricant or lubricating oil and use the right lubrication filling method.
Iii. Improper installation
1, the installation of precision single row roller bearing using brute force directly on the largest damage, is the main cause of deformation. 
2. The installation is not in place, the installation is deviated or not installed to the bearing position, resulting in too small bearing clearance.Inner and outer circles are not in the same rotation center, resulting in different centers.
Suggestion: Select appropriate or professional bearing installation tools, and use special instruments to detect after installation.
4.Fatigue
Fatigue ring breaking is a common damage mode of bearings. Common reasons for fatigue and ring breakage may be: long-term overload operation of bearings; Not timely maintenance; Equipment aging.
Suggestion: Select the appropriate precision single row roller bearing type and replace the fatigue bearing regularly and in time.
