Five quality inspection of bearing

About bearing the five quality check below the author to share together with everybody about bearing five quality check this knowledge, hope can help to you! Check on our bearings, must under the lights of the astigmatism, carefully observe the appearance and cracks, and other important parts of the bearing, often appear situation has the following five: 1, peeling and fold the two defects of local combined with matrix metal not firm, and its surroundings often exist in different degrees decarburization or poor phenomenon of carbon, the material easy caving, the indented or wear, bearing life and accuracy very unfavorable. 2, keep the riveting or welding quality mainly observe whether the rivet head deviation, skew, relaxation, lack of meat or double-fold eyelid, welding position is correct, solder joint is too large or too small, ever welding not firm or excessive cause jam phenomenon of roller. 3, rust, black and pitting black and pitting is easy to store water and dirt of defects, most likely to develop into rust. The corrosion is caused pollution sources, the installation of non-performing, early wear and fatigue serious corrosion will make the bearing damaged. 4, all kinds of mechanical wound abrasion, cut and bruised, crushed, can cause adverse bearing installation, causing partial load and stress concentration, caused by rotation precision and service life. 5, all kinds of cracks, such as crack raw material, forging, heat treatment of crack crack and grinding cracks, the crack in the process of bearing after operation, will become a source of stress concentration and expanded rapidly, cause bearing is broken, and great influence on bearing life and job security. In fact, for important use of bearings, bearing factory has been to 100% of their component parts magnetic or radiographic inspection. So everyone in the check bearing or other brand bearings, can according to this method to inspect oh, is very to use, if you have any other questions, welcome to consult our customer service, we would be happy to answer for you!
