In order to better carry forward the best condition of NSK bearing; the selection of NSK bearing smooth grease is directly related to the stability of the equipment. The selection of NSK bearing smooth grease must be considered from the following aspects:
1. Anti-rust function Anti-rust agent is the most insoluble in water. Grease should have excellent adhesion; the grease used in NSK bearings must have anti-rust effect. It can form an oil film on the steel surface.
2. Mechanical stability leads to leakage. During normal operation; grease will become soft during machining. Grease will be smashed into the NSK bearing by the bearing seat. If the mechanical stability of the grease is not good; during the work process, the layout of the soap will occur. Mechanical disintegration; the formation of grease is damaged; then the smoothing effect is lost.
3. Oil seal NSK bearing work process; oil seal is a necessary barrier to protect NSK bearings and smoothing agents from external pollution. No matter whether debris or moisture can enter the NSK bearing; to prevent the formation of damage to it. Correct equipment protection is carried forward NSK bearing is the most important factor in the longest service life. Together; must pay attention to the cleanliness of the bearing, the correctness of NSK bearing selection and the selection of appropriate equipment and protection. Others; bearings must avoid contamination by pollutants and moisture; And to ensure that the correct equipment and smooth. Therefore, NSK bearing configuration, oil seal condition, smoothing agent type and smooth cycle; even special protection plays the same and important person.
4. If the mixed grease is mixed with two kinds of incompatible greases, never mix the incompatible greases. Generally, the consistency will become soft; in the end, the NSK bearing may be damaged due to the simple loss of grease. If you do not know the original bearing Which kind of smooth grease; you must first completely remove the old grease in the NSK bearing table; to add new grease.
5. Classification of greases The consistency and smoothness of greases that are operated at a certain temperature affected by the operating temperature must be selected to have the correct consistency and outstanding smoothness at the same temperature. Grease is at a different operating temperature scale. The difference between the production can be roughly divided into low temperature, medium temperature and high temperature grease. Together; the difference is mainly based on temperature and working conditions: oil can be classified according to its allowable working temperature. One type of oil is called kneading or kneading resistance. And add molybdenum disulfide; together; an increase agent is added to strengthen the strength of the smooth oil film.
6. The selection of a grease is an important factor in the selection of a grease; if it is a fault to select a grease, all the measures to prevent the NSK bearing are also in vain. The viscosity of the base oil at the working temperature is able to supply a smoothing effect that is important. The viscosity is primarily affected by temperature; The temperature rises and decreases; when the temperature decreases, it rises. Therefore; the viscosity of the base oil at the working temperature must be known. Mechanical manufacturers generally specify the use of certain oils; but most standard smooth greases are suitable for a wide range of scales. .
Such as oscillation and the direction of the main shaft is horizontal or straight, cooling condition, sealing effect, peripheral environment. The following are several important factors in the selection of smooth grease: mechanical varieties, NSK bearing varieties and large.觯俣 段 ぷ髑榭 ぷ髑榭.
