How to correctly install non - standard bearings

There are many kinds of non - standard bearings, including size, shape, material, such as inner ring convex, outer ring plastic, outer ring grooves and so on, common no more than a few of the above. Although the installation conditions of non-standard bearings are not very strict, we must pay attention to some details. For example, when the installation is to do with the production of detritus or powder and water of the machine far away, to prevent pollutants into the bearing inside the bearing, especially sand for the life of bearing life damage is the most serious.
Before installation, must check the surface of the bearing, whether there are attachments, and scratches, sand, rust and other phenomena, if there is, please clean up in time. Because those attachments and scratches will form grinding of the inner ring surface of the non-standard bearing, resulting in bearing damage. The effect of corrosion is more serious, so the shaft neck and mounting base hole must be checked thoroughly before installation, if there are foreign objects or loss of the arms, then the bearing should be carried out after the installation. There are also conditions such as the cleaning or smooth of the inner and outer surfaces of the various connecting parts. If they are installed without cleaning, the displacement will be produced during the use of the bearing.
Although the installation of non-standard bearings is simple, but the external environment, especially the details are very important to do a good job in this respect, so that the life of non-standard bearings can be extended.
