SKF Bearing's “Appearance View Strategy”

The inspection of SKF bearings is usually carried out under astigmatism; careful investigation of the surface and cracks of the bearings is required:
1. Corrosion, black skin and pitting; the latter two are shortcomings of simple storage of water and dirt; the simplest is to carry out rust. Corrosion is a source of pollution causing poor installation, early wear and fatigue; severe corrosion will cause bearings Obsolete.
2, various cracks; such as the original data crack; casting cracks, heat treatment cracks and grinding cracks; these cracks in the future bearing operation; will become the source of stress gathering and agile expansion; the formation of bearing break; bearing life And the safety of the work has a great impact. In fact; the bearings for important uses; the bearing factory has 100% magnetic or radiographic inspection of its components.
3, the quality of the riveting or welding of the cage; the first investigation of whether the rivet head can be biased, tilted, slack, lack of meat or "double eyelids"; the orientation of the welding can be correct; the welding point is too large. Rejuvenation is a vassal of vassal."
4, a variety of mechanical scars; such as abrasion; scratches, crushes, bumps, etc.; will form a bearing device; resulting in eccentric load and stress gathering; the formation of rotation accuracy and the reduction in the number of life.
5, peeling and folding; some of these two shortcomings are not well connected to the base metal; and there are often different degrees of decarburization or carbon-poor appearance; the data simply collapse, underdentation or wear; bearing life and The accuracy is very arrogant.
The above items are some of the points in the purchase of bearing related loading and unloading personnel in the inspection of SKF bearings; in addition to some of the above-mentioned views; other such as poor typing quality; such as ambiguous, damaged handwriting; should be considered as defective; severe can also not test.
