INA bearing lubrication technique - bearing knowledge

Antirust performance used in the INA bearing grease must have antirust effect, rust inhibitor is best can not dissolve in water. Grease should have good adhesion force can form a layer of oil film in the surface of steel, even if grease is full of water can also be maintained. Mechanical stability grease in mechanical processing will become soft, lead to leakage. When there is a application example of vibration, grease will by INA bearing to INA bearings. If the mechanical stability of the oil is insufficient, grease can constantly thrown INA bearing, this will make the soap structure make mechanical disintegration and the use of grease are destroyed. Oil seal oil seal is necessary to protect INA bearings and lubricants in order to prevent the external pollution, regardless of sundry or moisture can penetrate INA bearings, in case of damage. Correct installation and maintenance is one of the important factors play INA bearing the longest service life. At the same time must pay attention to the clean degree of INA bearing, INA bearing choice is correct, and choose the appropriate installation and maintenance tools. INA bearings must prevent contamination by pollutants and moisture, must correct installation and lubrication. INA bearings with column design, the status of the oil seal, type of lubricants and lubrication cycle, and special maintenance plays the same important role. Mixed oil never mix incompatible grease, if two incompatible oil mixing, usually consistency will become soft, the last may be caused by loss of grease is easy to damage. If you don't know what kind of grease INA bearings used, first to remove INA bearings inside and outside of the old grease, can add grease filling. Oil classification according to the temperature and the working conditions to distinguish: grease can be classified according to their allowable working temperature, lubrication grease consistency and ability is affected by temperature, operating under a certain temperature INA bearings must choose imported under the same temperature has the correct consistency and good lubrication effect of oils and fats. Oil is different to make working temperature range, can be divided into low temperature ( LT) , medium temperature ( 太) And high temperature ( HT) Oil and grease. At the same time there is a certain type of oils and fats, called EP ( Extrusion proof. ) Or EM ( Resistance to extrusion and adding mos2) , with additives to enhance the strength of the lubricating oil film. Select grease if the wrong choice grease is all in vain INA bearing damage prevention measures, choose a kind of grease the base oil viscosity in the working temperature of it when it is important to be able to provide adequate lubrication effect, viscosity is mainly affected by temperature, it along with the temperature rising and falling, it increased when the temperature drops. So you have to know when the working temperature of base oil viscosity, machinery makers usually specified use some oil, most of the standard grease can be used with a wide range. Here are several important factors: choose the grease type low mechanical performance, such as vibration and the direction of the main shaft is horizontal or vertical INA bearing type and size of low working temperature low workload low cooling condition low sealing effect low speed range low if machinery and equipment to play to the best of peripheral environmental INA bearings must be properly the right job, and avoid high temperature, humidity and pollution of the environment. Proper lubrication and protection plan, as well as INA bearing condition monitoring work is the focus of the INA bearing the highest life. When the INA bearing damage may result in unexpected sexual equipment downtime. Even one hour of downtime, the premature failure of INA bearings may cause huge lost production. To ensure healthy operation, in addition to relying on quality INA bearings, but also pay attention to the operating environment, correct installation and regular maintenance.
