One, bearing selection stage, a number of factors need to be considered (for example: load, hardness, operating environment, etc.), first make a good bearing design bearing reaches its maximum lifetime value (refer to "factor bearing design considerations")
Second, the correct storage, bearing before installing the best should be kept in their original packaging. Need to stay in a clean, moisture free, relatively constant temperature environment. Rolling should stay away from dust, water and corrosive chemicals. Shake and vibration may never destroy the mechanical properties of the bearing, so the processing and storage process should avoid vibration.
The general level of the bearings should be stored for a long time after some heavy bearing upright, it will be deformed due to its own weight!
Also, coated with grease (or sealed) bearings need special care, because the oil after prolonged storage density change. When the bearing for the first time, there will be a certain degree of rotation noise. Therefore, in principle, these bearings should be set aside time to control FIFO!
Third, clean, which is very important for rolling bearings. Turn the ring bearing surface is very smooth, very sensitive to damage caused by pollutants. Particulate impurities will be subject to excessive rolling and rolling element bearings produce local pressure will eventually lead to permanent material fatigue.
Fourth, the comprehensive equipment to install, you should use the right tools bearing mounting and dismounting caution should choose the right tools! Industry experts estimate that premature bearing failure, 16% were due to improper installation caused. Generally speaking a lot of installation, usually take the appropriate bearing installation.
However, maintenance or replacement work, diverse environment! We recommend relevant drawings, maintenance manuals, product brochures need a closer look. Bearing components should also be absolutely clean!
Fifth, careful installation and removal.
1. Do not apply force on the rolling elements are mounted, which can easily lead to a partial rolling element and raceway contact surfaces of overload, resulting in premature bearing failure Zhen.
2, do not use any hard tools (such as a hammer, screwdriver, etc., I've seen too much with these two tools "hard" to install, too strong) direct knock the bearing surface, which can lead to rupture of the bearing ring or broken.
3, the general bearing not removed from the device, only the larger bearing only because preventative maintenance removed. Demolition process, first with the right tools, to ensure there is no damage to the adjacent parts!
Sixth, the correct proper lubrication, the lubricant can isolate the bearing surface, so as to reduce friction, to protect the metal parts and to prevent contamination and impurities. There are various greases for different operating conditions chosen.
Scroll part because of excessive, bearing lubricant experiencing long-term mechanical stress, and especially for a long time at high temperature, humidity or contaminated environment, the chemical nature of the lubricant will change. These will lead to lower quality lubricating removed. Therefore, to regularly re-lubricated bearings. Cycle consists of operating conditions.
