Equivalent load of 6804
Equivalent dynamic load
When a bearing bears both radial and axial dynamic loads at the same time, it is assumed that the load has a constant direction and magnitude, that is, the two loads that the bearing bears at the same time are regarded as one, which is the equivalent dynamic load. For radial bearings, it is expressed as pure radial load, which is called radial equivalent dynamic load.
The values of X and Y are listed in the table below:
Equivalent static load
When a bearing is subjected to both radial and axial loads at the same time, the assumed load that causes the permanent deformation of the bearing to be equal to the permanent deformation of the contact center between the rolling element and the raceway that bears the maximum load is the equivalent static load. . Radial bearings are represented by purely radial loads.
Application of 6804 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 6804 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 6804 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.
