I, INA bearings selection phase, taking into account a number of factors (example: load, hardness, operating environment, etc), good bearing design will first make bearing reaches its maximum life values.
Second, the correct storage, bearing before installing the best should be kept in their original packaging. Need to stay in a clean, dry and free of moisture, a relatively constant temperature environment. Rolling bearings should be kept away from water and dust, corrosive chemical substances. Shakes and vibrations may forever damage mechanical properties of bearing, therefore should be to avoid vibrations during processing and storage.
General level INA bearings should be saved, after some heavier bearing vertical drop for a long time, deformation due to own weight!
Also, coated with grease (or sealed) bearing need special care, because through the storage density after the oil change. When the bearing is used for the first time, there will be a certain degree of rotational noise. Therefore, set aside time for such INA bearings should be controlled according to the FIFO principle!
Three clean, which is very important to rolling bearings. Plane of rotation of the bearing rings are very smooth, very sensitive to damage caused by pollutants. Particles of impurities will be excessive rolling, rolling elements and partial pressure in the bearings will eventually lead to permanent material fatigue.
Four fully installed equipment, the bearing should be carefully using the appropriate tool installation and removal (can refer to the demolition of the bearing series video). Should select the right tools! Industry experts estimate that INA bearing premature failure, 16% were caused by incorrect installation. Generally a large number of installation, would normally take appropriate bearings installed devices.
But in the maintenance or replacement work, environmental diversity! Suggest that you, the relevant drawings, maintenance manuals, product specifications need to look at. Bearing components must be kept absolutely clean!
Five, careful installation and dismantle, previously had repeatedly referred to the bearing installation (if we have similar problems, here are some bearing installation articles), simple summarize again:
1, do not exert force on rolling elements, this can easily lead to local overload of the rolling elements and contacts on the seat, causing premature failure of the bearing.
2, do not use any hard tool (such as hammers, screwdrivers, too much with these two tools I've ever seen "hard" installed, is too strong) knock on the bearing surface directly, this will cause the bearing ring fracture or broken.
3, INA bearings in General will not be removed from your device, only the larger bearings will be removed due to preventive maintenance. Demolition process, first of all, you should use the right tool, to ensure that the adjacent parts is not corrupt!
Six, the correct proper lubrication, lubricants, you can isolate bearing surface, which reduces the friction to protect metal parts and to prevent pollution and impurities. There are all kinds of grease can be used by different choice of operating conditions.
