Correct installation and maintenance is an important factor to give full play to the longest service life of ina bearings
At the same time, attention must be paid to the cleanliness of bearings, the correctness of bearing selection, and the selection of appropriate installation and maintenance tools
In addition, the sliding bearing must be protected from contamination by pollutants and moisture, and ensure that it is correctly installed and lubricated
Therefore, the design of bearing arrangement, the condition of oil seal, the type and lubrication cycle of lubricant, and even special maintenance all play the same and important role

Never mix incompatible greases with mixed greases
If two incompatible greases are mixed, their consistency will soften, and finally the sliding bearing may be damaged due to the easy loss of grease
If you don't know what kind of grease ina bearings originally used, you must thoroughly remove the old grease inside and outside the bearings before adding new grease
Generally, the lubricant has the following basic requirements: (1) it has sufficient lubrication, that is, it can reduce the friction of the bearing and inhibit the harmful wear process in the bearing
The friction resistance should be small and the anti-wear ability should be large
(2) Prevent the bearing from rusting, and it will not cause the corrosion, deterioration or deformation of sliding bearing components (such as copper cage, rubber seal, etc
)
(3) It can always maintain the necessary lubrication performance within the upper and lower limits of the specified working temperature, with stable chemical composition and little viscosity change
(4) Within the upper and lower limits of the specified working speed, a sufficiently thick oil film can be established; It is clean without impurities and has good defoaming property (5) Within the required working period or inventory period, the physical and chemical properties are stable enough not to affect the use of quality degradation
(6) The maintenance shall be as simple as possible, and the auxiliary devices shall be as few as possible
(7) On the premise of meeting the above technical requirements, strive to save economically

Additional requirements for lubricants (1) good cooling effect
(2) It has strong adhesion to the lubricated surface, and the leakage, dripping or scattering should be as few as possible; Good water separation
