SKF bearing the preparation before installation and removal

Before the installation, should be ready all the necessary spare parts, tools, equipment and related data, and so on. Carefully study the drawings and related instructions, to determine the correct installation order of different parts. Carefully check SKF bearing, axis, seals, and other parts of SKF bearing configuration, to ensure that the mating surface clean and good, should also be a special check the screw hole, catheters or groove, in order to prevent some processing residues. The casting SKF bearing, shall ensure that no core sand on the surface of the some without machining, and place all the burr. Inspection of all components in the configuration of SKF bearing dimensional tolerance and shape tolerance, related parts must meet the required precision and conform to the provisions of the tolerance range, SKF bearing can play their performance. The diameter of the cylindrical shaft and hole, general with micrometer or inside diameter micrometer in two cross section and four different position measurement. Journal of the taper ring gauge available measure, special taper gauge or sine bar. Measurement results and related inspection, it is suggested that keep as a record, in order to offer the reference when needed. When measuring, components and measuring instrument should be kept in roughly the same temperature, so as to ensure the accuracy of measurement. That may need to components and measuring equipment in the same place quite a time, in order to achieve the same temperature. This is especially important for large SKF bearings and related components. SKF bearing should be retained in the original packaging until the moment of before installation to prevent dirt and other contaminants. In the general case, no need to remove the factory before besmear is on SKF bearing anti-rust agent, just wipe SKF bearing outer circle and inner hole. But if the SKF bearing with grease lubrication and application in high or low temperature, or all of the grease is not compatible with the rust inhibitor, is necessary before installation and carefully dry cleaning the SKF bearing in order to avoid damage to the role of the grease. If the SKF bearing due to improper handling may be pollutants enter, will also be necessary to the SKF bearing cleaning and dry before installation. From the original packaging of SKF bearing, if relatively thick rust inhibitor on the surface or have higher viscosity, is also need to SKF bearing cleaning and dry. Part of SKF bearing outside diameter greater than 420 mm oversize may have this kind of situation, the situation can use oil or paraffin solvent to remove SKF bearing on preservatives. If you are using SKF bearing with seals or dust cover, because the factory has to fill grease, not clean before installation.
