•  The relative humidity should be maintained below 60 percent 

 

  and the surfaces should be dry.

 

•  The storage area should be kept free from airborne

  

  contaminants such as, but not limited to, dust, dirt, harmful 

 

  vapors, etc.

 

•  The storage area should be isolated from undue vibration.

 

•  Extreme conditions of any kind should be avoided. 

Due to the fact that Timken is not familiar with your particular storage 
conditions, we strongly suggest following these guidelines. However, 

you may be required by circumstances or applicable government 
requirements to adhere to stricter storage requirements.

Most bearing components typically ship protected with a corrosion-
preventive compound that is not a lubricant. These components 
may be used in oil-lubricated applications without removal of the 
corrosion-preventive compound. When using some specialized 
grease lubrications, we advise you to remove the corrosion-
preventive compound before packing the bearing components with 
suitable grease.
