DNED Bearing Lubrication

    Posted: 2013-11-23

 

The main purposes of lubrication for DNED bearing are to prevent metallic contact between the rolling elements, raceways and the cage, and also to prevent the bearing from corrosion and wear. Additional functions are sealing and cooling of the bearing.

 

DNED bearing may be lubricated with grease or oil, in special cases with a solid lubricant, the choice of which depends primarily on the temperature range, operating speeds, and loading conditions of the bearings concerned.

 

All lubricants must be changed from time to time because their properties deteriorate as a result of aging and contamination of the lubricants.

 

The functions of some grease and oil lubricants are listed below for references.
