First, the bearing selection stage, need to consider many factors (e.g.: load, hardness, operating environment, etc.), first make a good bearing design bearing value reached its maximum life span.
Second, proper storage, bearing the best before installation 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 should be avoided during vibration.
General level of the bearing should be preserved, and some heavier bearing long vertically, it will be deformed due to its own weight!
Also, coated with grease (or sealed) bearings need to be especially careful, because after the oil after a long storage density will change. When bearing the first time, there will be some degree of rotation noise. Therefore, this type of bearing the FIFO principle should be set aside time to control!
Third, clean, and this bearing is very important. Rotation of the bearing ring is very smooth surface; the damage is very sensitive to pollutants. Particulate impurities will be rolling over rolling element bearings produce in the local pressure will eventually lead to permanent fatigue.
Fourth, the full re-installation of equipment bearing the appropriate tools should be used carefully to install and remove (you can see the demolition of the bearing series video). Should choose the right tools! Industry experts have estimated that premature bearing failure, 16% were due to improper installation caused. Usually installed in large numbers in terms of the general will take the appropriate installation of equipment bearing.
However, maintenance or replacement works, the environment, a variety! Suggest that the relevant drawings, maintenance manuals, product brochures need to carefully look at. Bearing components should also be kept absolutely clean!
Fifth, careful installation and removal, has repeatedly mentioned before bearing installation (if you like problem, here are some articles bearing installation), again briefly summarize:
1, do not install the force applied on the rolling elements, which can easily lead to the rolling elements and the contact surface of the seat of local overload, which lead to premature bearing failure attained.
2, do not use any hard tools (such as hammer, screwdriver, etc., I have seen too many tools with both "hard" to install, too strong) direct knock on the bearing surface, which causes the bearing ring fracture or broken.
3, the bearing does not normally removed from the device, only the larger bearing will be removed for preventive maintenance. Demolition process, first with the right tools, to ensure no damage to adjacent parts!
