The reason with the rusty for your imported NSK Bearings
SKF Bearings
The
factors for the rusty on the Producing motor bearing for instance the
SKF Bearings, NSK Bearings and FAG Bearings are complex. Possibly it is
the improper handling process for the bearings which include the SKF deep groove ball bearing,
SKF deep groove ball bearing and NSK bearings. To the other hand, the
rusty may possibly be brought on from the moisture and corrosion induced
from the mist. Currently, the Chinese renowned bearing supplier, which
website is www.hk-nkf.com , would inform you the reason for your bearing rusty.
Through
the facts with the hk-nkf.com, we've got identified that you will find
four principal elements from the volatile acid from the paint which most
motor plants have making use of.
The 1st will be the non-reacting
raw acid component on the low-molecular-weight paint like the anhydrous
iso-phthalic and terephthalic acid, anhydrous maleic acid and the
fumaric acid.
The 2nd may be the acid component which continues to be
produced from the curing paint including the phenolic modified paint
and also the processing of formaldehyde water into formic acid.
The
third is definitely the heat or oxidation and decomposition with the
resulting together with the decrease fatty acids like the formic acid
and acetic acid.
The acid component produced from the cured paint
products within the decomposition of water. The main acid element of
insulating paint is formic acid. There exists a shut romantic
relationship among the amounts of formic acid with all the degree of
corrosion.
Since the make clear from your engineer in the www.hk-nkf.com,
the method from the Grease adsorbing into the volatile acidic
components from the paint is definitely the primary purpose for creating
the rising from the acidic component as well as the corrosion in the
SKF deep groove ball bearing and FAG deep groove ball bearing.
The
functioning principle in the grease should be to utilize the layer of
grease to separate the ball and the inner and outer raceway. It could
use the oil viscosity qualities to attach for the surface with the ball
as well as the raceway and separated metal interface of the ball with
all the inner and outer raceways. This type of situation would reduce
the put on and tear on the metal surface and defend the metal from
corrosion of air and water. It could also minimize vibration and noise
and make the skf bearing catalog for instance the NSK deep groove ball bearing have smooth rotation.
But
following the deterioration from the grease, the viscosity with the
grease will modify plus the separator perform and adhesion
characteristics on the grease will disappear. This would result in this
kind of consequences. Very first, the acidic components of your
insulating paint would direct affect the surface on the metal and induce
the corrosion of imported bearings for example the SKF Bearings and NSK
Bearings. The 2nd is that it is going to bring about the straight touch
amongst the ball and also the inner and outer raceway.
