Agency operation, parts for mounting double row deep groove ball bearings allows a certain degree of temperature, when you touch body shell by hand, should not feel hot as normal, rather it indicates that the temperature is too high.
Cause the failure of double row deep groove ball bearings, statistics and poor lubrication or inadequate lubrication, 35% pollution 25%, improper installation, 13% 11% of the bearing mixed improperly, improper selection, 8% quadratic loss 7%, product defects and material 1%, therefore installation of the basic requirements are:
1, the installation personnel receive special training.
2, check the shape and position tolerances of the mating surfaces of the bearing.
3, the installation site clean.
4, then open bearings after installation are ready to complete the package.
5, do not clean up of bearing rust preventive oil.
Double row deep groove ball bearings have noise causes are more complex, and one is the inner and outer rings of bearing surface wear. Due to this wear, damage bearings works with shell, stainless steel bearings and shafts, leading to axis deviation from the correct location, noise resulting from the axis at high speed.
When tired of double row deep groove ball bearings, metal Flake on the surface, would also make abnormal noise of radial clearance of bearings increases. In addition, insufficient bearing lubrication, formation of dry friction and bearing broken produces abnormal noises. After the bearing wear loose, stay loose, damaged, will also have an abnormal noise bearing failures.
