Should be thoroughly cleaned before the bearings are mounted. When you install, you should use the special tool INA bearings straight and evenly press into, do not use hand hammer percussion, specifically prohibits tapping directly on the INA bearing. When the bearing seat and hole coordinating pedestal looseness, should fix a hole or replacement of bearings, not pitting in the mating surfaces of the bearing or the pad method of copper skin barely used. Bearing removal pull pull the bearing should be used when appropriate, do not use chisels, hand hammer percussion such as bearings.
Commonly used lubricant lubricants and greases for rolling bearings in two ways. When the circumference of the shaft when the speed is less than 4-5m/s, or car parts are lubricated by lubricating oil cannot be used on are using grease lubrication. Grease-lubricated seals are the advantages of simple structure, loss of grease is not easy, is not affected by the temperature, you can add lubricating grease once used a long time.
Use grease should pay attention to two issues, one is to press the car specification of requirements, selection of appropriate grade of grease. For example, a car water pump bearing selection m. Mounir Bouchenaki grease would be inappropriate, because of its poor water resistance. II joined the INA bearing grease in just the right amount, generally filling bearing cavity 1/2-l/3, too much is not only useless, also will increase the functioning of INA bearing resistance, to warming fever. To be aware of the special auto wheel hub bearing, promotion of "air hub lubrication", that is, only you can apply a layer of the right amount of grease in the bearing, otherwise, is not only a waste and poor heat, also putting grease heated spills that may affect braking performance.
Lubricating the advantage of friction resistance is small, and thermal, main bearing for high-speed and high ambient temperature. Grades according to the specification of a car requires selection of lubricating oil, and timely replacement of car maintenance cycle, release old oil to clean the body and then add the new oil, oiling should be added to the prescribed marking, or flush with filler (as the car specific structure, requirements may be), not more.
No lubrication is a problem fixed. Artificial maintenance of situations, it is impossible to achieve, automatic lubrication system, could be developed in order to achieve the best results. Need grease, tools and effective lubrication technology, will help to significantly reduce downtime. Although you can install "free" seals of all types of bearings, INA bearing early failure I still have 36% of grease which is incorrect and improper use of technology. Improper lubrication of any inevitable failure INA bearings in normal life. Bearing machinery and equipment is often the most difficult part of the work.
Bearings are precision components, INA bearings and oil pollution, will not run. INA bearings in addition, has all of the grease sealed maintenance-free, at least 14% pollution only if the premature failure of a small portion of the use of all bearings bearings due to significant. Bearings with excellent manufacturing and design capabilities, able to provide a variety of harsh working conditions of sealing solutions.
Rolling bearings for clean is very important. Bearing ring turning and rolling elements of surface roughness is usually one-tenth μ m, so smooth surfaces are very sensitive to damage caused by pollutants. Rotational surface lubrication layer is typically a 0.2~1 between μ m, size is greater than the lubricant particles of impurities will be excessive rolling bearings of rolling elements in steel by partial pressure, will eventually lead to permanent material fatigue. In addition to this, the external environment dust particles in the size up to 10 μ m, INA bearing damage may also occur. Therefore, clean, dust-free environment for storage and installation of INA bearing, is essential.
