Preparations before SKF bearing installation

wallpapers News 2020-11-17

Nowadays, bearings are more and more widely used. Incorrect installation methods may shorten the service life of bearings. Now, we provide some information about bearing installation preparation skills: According to the technical requirements on the design drawings for installing SKF bearings, before installing SKF bearings, please use appropriate measuring tools to check the processing and quality of the shaft, seat hole and related parts. Then start the cleaning step of the bearing.


Cleaning process

When cleaning a large number of SKF bearings at the same time, first use hot machine oil with a temperature of 90 to 100% to melting the encapsulating oil. At the same time, use a tool with no edge and no chipping to dig out all the old oil. Rinse the oil with kerosene, and finally clean it again with gasoline. After cleaning, wear film gloves and put the bearing on a clean cloth or paper on the workbench to dry.

The assembly surface should be cleaned with clean gasoline, kerosene, toluene or xylene and other solutions, and dried with a clean cloth, and then coated with a thin layer of lubricating oil, which will make the installation and operation more convenient. If there are bumps, burrs, rust spots or solid particles on the assembly surface of the bearing mesh shaft and the seat hole, it will not only make the bearing installation difficult and make the installation position incorrect, but the solid particles will have a grinding effect if they fall into the bearing. , When the bearing rotates, it will scratch or scratch the working surface of the bearing, so it must be carefully checked before installation. If the above-mentioned defects are found, they should be corrected. For example, use an oil file to remove burrs, raised bumps, and rust spots, and polish with a fine emery cloth. Another example is to clean solid particles and dirt.


Note that sealed SKF bearings cannot be cleaned in this way, and the inside of the seal should remain intact. Before installation, open the SKF bearing package, immerse it in the above-mentioned gasoline and other liquids and rotate it gently by hand, ensuring that the sealing oil on the surface of the cage, body and raceway is thoroughly cleaned.
