The 6219 Bearing Lubricants
The lubricants in rolling bearings are mainly employed to prevent direct metallic contact between each rolling and sliding elements. Bearing performance and service life are largely dependent on the suitability of the lubricating system and lubricant to the application.
NSAR premium 6219 bearing is made in China and 6219 bearings Made of bearings steel,bearings steel with higher and more uniform hardness and abrasion resistance.The most rare is that of bearings steel with ultra-high hardness at the same time,have very strong elasticity.The assurance of hardness can prolong the service life of bearings.
