Linear motion bearings to install

The surface of the linear motion bearing components and cooperate with the surface of the parts, if there is a bump, rust layer, the wear debris, sand, dust and dirt, a linear motion bearings is very difficult to install, lead to incorrect assembly position; Second, these attachments form abrasive, easy to work surface friction non-standard linear motion bearings, affect the assembly quality. Therefore, before the installation, should check the surface of the journal, the surface of the shell, shell of end face and shoulder such as bushings, washer and so on with the connection parts surface. If there are rust layer, it can be finely, and fine emery cloth light, but also to remove linear motion bearing component of the surface of the connection and connection parts. For can be separated from the inner ring and outer ring of linear motion bearings, don't swap outer ring in order to avoid affect the quality contact. For non standard linear motion bearings, linear motion bearings of rolling element shall not be taken apart and mix, in order to avoid the installation location chaos, affect the precision. Installing a linear motion bearings, to facilitate the check code linear motion bearings, not wrong, linear motion bearing ring of a literal should be placed and installed. Linear motion bearings for interference in a big, and to facilitate the installation, you must install preheating; Work closely to light metals linear motion bearing hole ( Such as aluminium linear motion bearing) , low hardness, prevent the compression of linear motion bearing outer ring. When linear motion bearing box scratches the surface of the shell hole and pull, deal with the heating and installation. Heating methods usually include the linear motion bearing ring into the linear motion bearings or separated with clean engine oil in the tank, the oil spill non-standard uniform linear motion bearings and heating. When the temperature reaches 80 - 90 ° C, will be removed and wipe clean. Fuel tank can be made by 2 - 3 mm thick plate made of porous plate placed in 50 - from the bottom 70 mm, linear motion bearings placed on porous plate heated. Its purpose is to prevent impurities in oil sediments into linear motion bearings. However, for both sides with dust cover or seal of the linear motion bearings, because in the process of manufacturing added lubricant, so in the early stages of the installation is not heated.
