For corrosion of the bearing, the oil removal after cleaning, derusting processing to deal with the.
Commonly used method is mechanical cleaning and chemical cleaning.
(
A)
Mechanical cleaning use sandpaper no. 000 and no. 1, 0, 00 number fine emery cloth, grinding by hand.
Grinding, the direction should be consistent, uniform.
Can also be used on the rust parts with paste, and then use cotton cloth for grinding.
Should choose according to the degree of corrosion paste type and operation procedures.
For corrosion is serious, should use coarse grinding paste first, then use the paste, finally paste with fine grinding of coarse grinding;
Rust is very light, directly grinding can achieve the desired effect.
When the dosage is small, fine grinding paste is available on the market sales of finished products and other suitable products.
Dosage is bigger, can abstain, homemade recipes in the following table.

Chemical cleaning chemical cleaning method is to use chemistry to remove the rusty spot on the bearing.
Its operating process is as follows: remove kaifeng bearing cleaning grease and wash with hot water to irrigate with flowing of cold water, chemical cleaning,
Add inorganic acid corrosion inhibitor configuration of cleaning fluid in bearing corrosion, removal of the metal surface rust)
To irrigate with flowing of cold water, and to irrigate with flowing water, purification,
One by one with antioxidant chromic anhydride coating on the surface of bearing metal to produce dense oxide layer)
To dry, oil seal.
Cleaning fluid formula and work specification see table.
The 1, 2, 3, 4 in the table below refers to the four different types of process, should choose according to different materials, performance, application.
