2．inspection SKF bearing models, ready to install the tool
SKF Bearing Inspection, the size meets the installation requirements, and select the best method of assembly according to the SKF bearing structural characteristics and co-ordinated with the various parts, ready to install with tools and gauges. Installation tool hand hammer, copper rod, sleeve, special plate, screw mosquito fixtures, presses, etc., the amount of vernier caliper, micrometer, dial gauge.
3．test SKF bearing assembly surface
SKF bearing assembly surface and co-ordinated with the surface of the part, if the bumps, rust layer, presence of debris, sand, dust and dirt, an SKF bearing installation difficulties, resulting in incorrect assembly location; two of these attachments to the formation of abrasive , easy to clean loss of SKF bearing surface, affecting the assembly quality. Therefore, the pre-installation deal with journal, the surface of the bearing shell hole, the end of the shoulder, and connecting parts such as bushings, gaskets, end with the surface, a careful inspection. If corrosion layer, can be used fine file file out, fine emery cloth polish, but also to clear the attachments on the SKF bearing assembly surface and its connecting parts.
