What is the SKF bearing surface; the appearance of SKF directly determines his authenticity. The original Swedish SKF view should be carried out under the astigmatism; on the surface of the bearing. Detailed investigation of cracked bearing marks and other parts.
Various mechanical scars; scratches. Bruise. Bumps, etc.; inducing eccentric load and stress gathering; will cause poor installation; spheroidal roller bearings such as wear; formation of rotation accuracy and reduction in service life.
Peeling and folding; and there are often different types of decarburization or carbon-poor appearance around; the data simply collapses. Concave or worn; some of these two shortcomings are not well connected to the base metal of the tapered roller bearing; the life and accuracy are very arrogant.
Various cracks; will become the source of stress gathering source and expand agilely; such as the original data crack; these cracks in the future operation; the formation of bearing crack; casting cracked cylindrical roller bearing pattern. Heat treatment cracks and grinding cracks, etc.; greatly affect the bearing life and work safety. In fact; about the use of important Wafangdian bearing factory; bearing factory has 100% magnetic or radiographic inspection of its components.
The quality of the riveting or welding of the cage; whether the orientation of the welding is correct; the joint of the welded joint is still too large.

Black skin and pockmark; the latter two are the shortcomings of simple storage of moisture and dirt in Harbin Bearing Factory; the simplest is to form rust. Corrosion is caused by poor equipment. Early wear and exhaustion of contaminated sources are full of roller bearings; severe rust will void.
