Causes and Countermeasures of bearing common problems

Question Reason Countermeasure
noise High metallic tone Poor lubrication Use proper lubricant and quantity
The clearance is too small Use proper clearance
Poor installation Check the accuracy of shaft and bearing seat and check the installation method
Low metal tone Overload Check the installation and preloading values
Regular sound There is an indentation on the raceway surface Avoid shock loads
Corrosion or injury Check sealing device and relubricate
Surface spalling of raceway Use appropriate interference, clearance, lubrication and installation methods
Irregular sound Foreign matter entry Check sealing device and relubricate
Excessive clearance Use proper clearance
Rolling element damage or surface spalling Use proper load clearance
Inflexion The increase of temperature leads to the change of clearance Check the material of shaft and bearing seat, and use proper clearance
Rolling injury The proper method and installation of interference clearance
Abnormal temperature rise The clearance is too small Use proper clearance
Poor installation Check the material of shaft and bearing seat, and use proper clearance
Overload Check the clearance, interference and preloading
Poor lubrication Use proper lubricant and quantity
creep Check the interference, check the accuracy of shaft and bearing seat
Lubrication failure Too much grease Use the proper amount of lubricant
Foreign matter entry Inspection of cleaning device and sealing parts
