1, the installation and choice of venue requirements
Space should be installed with lathes, grinders and other machinery and equipment from a distance. Space should be clean, always kept dry clean, prevent iron chips, grit, dust, moisture into the bearing.
2, inspection bearing type, prepare for installation tools
Survey of SKF bearings type, size meets the installation requirements, and based on the structural characteristics of bearing and tie in with various parts, choosing the appropriate assembly method, you are ready to install the tools and measuring tools. Commonly used installation tools Bishop, copper rods, sleeves, private plate, screw clamps, presses in mosquito, with Vernier caliper, micrometer, micrometer and other forms.
3, inspection of bearing mounting surface
SKF bearing mounting surface and tie in to the part surface, such as scratches, corrosion layers, grinding dust, grit, dust, and soil, a bearing installation difficulties, resulting in incorrect Assembly position; the second is the attachment formation of abrasive, easy clean bearing surface loss, affecting the quality of Assembly. Therefore, install the front axle, bearing shell hole surface, face, shoulder and connecting parts such as bushings, washers, end of mating surfaces, a careful inspection. If there is corrosion layer, smooth file available file off, sand cloth illuminated, while also clearing the surface of the bearing Assembly and attachment of the connected parts.
Inner and outer rings SKF bearings are separable, do not mistake so as not to affect contact quality interchangeable between the outer ring. For bearings and to refrain from arbitrary mixing of rolling out of the bearing, in order to avoid installation location disorders affecting the accuracy.
When mounting SKF bearings, for ease of check bearings code does not wrong, typing faces of the bearing rings should be placed and installed outside.
