The correct use of rolling bearings

Update:2017-07-26

   1. Bearing disassembly
   The bearings should be cleaned before installation. Installation, should use a special tool will be flat evenly press the press, do not use the hand hammer percussion, in particular, prohibit direct impact on the bearing percussion. When the bearing race with the seat hole with loose, it should repair the seat hole or replace the bearing, do not use the bearing with the surface of the pitting or mattress method of barely use. Bearings should be used when the appropriate pull out the bearing pull out, do not use chisels, hand hammer and other percussion bearings.
   2. bearing lubrication
   Roller bearings commonly used lubricants are lubricants and grease two. When the peripheral speed of the shaft is less than 4-5M / sec, or if the lubricating oil can not be lubricated on the car, grease lubrication is used.
   Grease lubrication has the advantage of simple sealing structure, grease is not easy to lose, little affected by the temperature, plus a grease can be used for a long time.
   Use grease to pay attention to two issues, one is to follow the requirements of the car manual, use the appropriate grades of grease. For example, the car pump bearings should not use Naji grease, because of its poor water resistance. Second, the grease in the bearing to be appropriate, generally only fill the bearing cavity 1 / -1 / 3 is appropriate, too much not only useless, but also increase the bearing running resistance, so that heating up. Special note is the car wheel bearings, to promote the "empty hub lubrication", that is, only a layer of grease on the bearing can be coated, otherwise, not only waste and poor heat, but also make the grease heat spill, may affect Brake performance.
   Lubricant lubrication has the advantage of small friction resistance, and can heat, mainly for high-speed and high temperature working environment bearings. Lubricant grades should be selected according to the requirements of the car manual, and then replace the car maintenance cycle in a timely manner, after the release of old oil to the organization after the cleaning and then add new oil, refueling should be added to the provisions of the marking, or with the fuel flush (Depending on the specific structure of the car, the request may be), not more.http://www.bhsbearings.com/
