Basic dynamic load rating and basic rated life of 6803 bearing
Correction of basic dynamic load rating due to temperature
Different bearing hardness and operating temperature have different effects on bearings, and the basic dynamic load rating, which depends on the physical properties of the bearing material, decreases as the temperature increases. Therefore, the basic dynamic load rating can be corrected using the following formula at high temperatures:
Modification of basic fixed life of 6803 bearing
The general application of bearings requires the bearing to be able to operate under displacement, bidirectional load, high-speed rotation or the combination of two or more bearings. These operating conditions will change the bearing life and be solved through correction factors, such as reliability, bearing material and other operating conditions.
Application of 6803 bearing:
NSAR are widely used in household appliance. micro-motors electrical tools garden machinery, motorcycles,automobiles,medical equipment, sports machinery, textile machinery and agricultural machinery.
Advantages of 6803 bearings:
The bearings we manufacture are all low noise,low vibration,low friction, high precision, high sealed,high turning speed and long life.
Quality assurance certificate of 6803 deep groove ball bearings
Quality is the key point for the NSAR. bearing’s growth and development, which always regards the improvement of high quality and service as the long-term-development strategy. NSAR has passed IS09001: 2000, 1S09001: 2008, and will struggle for the NSAR in long term.
