Serion bearing the characteristics of 1. Dry friction coefficient of low-friction race bearings is half of the general water-lubricated bearings, race dragons of low friction, but also wear-resistant, lower starting torque, the main factor to eliminate adhesive wear. 2. Long service life, anti-wear ability Because the dragon's elastic properties, when the friction particles into the bearing, which is pressed into the dragon inside, and then by elastic axis with the scroll, dropped into the sink after the discharge, there will be no card On the bearings, another source of friction is formed, thus minimizing bearing and shaft wear3. Dry start race dragon can dry in a certain period of time. About 1-2 minutes without prior lubrication with water, if the pump pump interruption, it will not damage the bearings. Sealed forced lubrication of bearings, water lubrication system into the dragon, you can greatly avoid the lubrication system failure, resulting in bearing damage 4. Easy to process 5. Increase pump efficiency 6. Overload capacity 7. Elastic, tough 8. Easy to install 9. Easy to modify 10. Dragon Bearing, there is no limit on the length of life 11. Water, oil lubrication can race oil dragon will not rise, is the best oil and water mixed environment bearings. Conversely, the metal used in lubricating oil, can not be washed away by water. Instead of metal bearings, it is not allowed to be oil pollution, and there are oil and other applicable issues.
