Selection Skills of Bearing Lubricating Oil in Pebble Crusher

1, anti-rust performance
Used in the bearing grease must have anti-rust effect, rust inhibitor is best not soluble in water. Grease should have good adhesion, and can form a layer of oil on the surface of the oil film.
2, mechanical stability
Grease will become soft during machining, resulting in leakage. Normal operation, the grease will be thrown into the bearing bearing bearing. If the mechanical stability of the oil is not enough, during the operation, the soapy structure of the grease will be mechanically disintegrated, causing the oil to be destroyed, thereby losing the lubrication effect.
3, oil seal
Oil seal is necessary to protect the bearings and lubricants from external pollution barriers, bearing the operation process, regardless of debris or moisture can not penetrate the bearing, to prevent damage to it.
Proper installation and maintenance is an important factor in maximizing the bearing life. At the same time, must pay attention to the bearing cleanliness, bearing the correct choice and the selection of appropriate installation and maintenance tools. In addition, the bearings must be protected from contamination by contaminants and moisture and are guaranteed to be properly installed and lubricated.
4, mixed with grease
Never mix the incompatible grease, if the two incompatible grease mix, usually its consistency will become soft, and finally may be easily lost due to grease caused by bearing damage. If you do not know what kind of grease used in the original grease, you must first clear the old grease inside and outside the bearing before adding new grease.
5, the classification of oil
Mainly according to the temperature and working conditions to distinguish: grease can be classified according to their allowable working temperature, grease consistency and lubrication capacity is affected by the working temperature, the operation of a certain temperature bearings must be selected at the same temperature with the correct consistency And good grease lubrication effect. Grease is made in different operating temperature range, can be divided into low temperature, medium temperature and high temperature grease. At the same time, there is a class of grease known as resistance to extrusion or resistance to extrusion and add molybdenum disulfide, at the same time, in which additives are added to enhance the strength of the lubricating oil film.
