Anti-rust performance The grease used in the outer ball cylindrical roller bearing must have anti-rust effect, and the anti-rust agent can be insoluble in water. The grease should have good adhesion and can form an oil film on the surface of the steel, even if the grease is full Water can also be maintained. Mechanical stability Grease will soften during machining, causing leakage. In the case of applications with vibration, the grease will be thrown into the bearing from the outer ball cylindrical roller housing. If the mechanical stability of the grease is not enough, Grease will be continuously thrown out of the bearing, which will cause mechanical collapse of the soap structure and damage to the use of grease. Oil seal Oil seal is necessary to protect the bearing and lubricant to prevent foreign contamination, regardless of debris or moisture can not penetrate into the bearing. , to prevent damage. Correct installation and maintenance is an important factor for the long service life of the bearing. At the same time, attention must be paid to the cleanliness of the bearing, the correctness of the bearing selection and the selection of appropriate installation and maintenance tools. The bearing must be protected from contamination and moisture. Air pollution must be properly installed and lubricated. The design of the bearing equipment, the condition of the oil seal, the type of lubricant and lubrication cycle, and even specialized maintenance all play an equally important role. Mixing grease Never mix incompatible greases , If two incompatible greases are mixed, the consistency will usually become soft, which may cause losses due to the easy loss of grease. If you do not know which grease was originally used in the bearing, first remove the old grease inside and outside the bearing, Grease can only be added. Greases are classified according to temperature and working conditions: Greases can be classified according to their allowable working temperature. The consistency and lubricating ability of greases are affected by working temperature. Bearings operating at a certain temperature must be selected in Greases with the correct consistency and good lubrication at the same temperature. Greases are manufactured in different operating temperature ranges and can be divided into low temperature (LT), medium temperature (MT) and high temperature (HT) greases. There is also a class of greases Grease is called EP (extrusion resistance) or EM, and additives are added to strengthen the strength of the lubricating film. If you choose the wrong grease, all measures to prevent bearing damage will be in vain. Choose a grease whose base oil viscosity is at the working temperature. It is very important to provide sufficient lubricating effect at all times. The viscosity is mainly affected by temperature. It decreases with the increase of temperature, and it increases when the temperature decreases. Therefore, it is necessary to know the viscosity of the base oil at the working temperature. Machine manufacturers usually A certain kind of grease will be formulated and used, and most standard greases can be used in a wide range.
