The five reasons TIMKEN bearing overheating

TIMKEN bearing inspection to be carried out under astigmatism lamp, appearance, cracks and other parts of the TIMKEN bearing careful observation. 1, peeling, and fold: the two kinds of defects of local combined with matrix metal not firm, and its surroundings often exist in different degrees decarburization or poor phenomenon, carbon material easy caving, the indented or abrasion, the TIMKEN bearing life and accuracy very unfavorable. 2, maintains a riveting or welding quality: mainly to observe whether the rivet head deviation, skew, relaxation, lack of meat or double-fold eyelid, correct the position of the welding, solder joint is too big or too small, for welding not firm or excessive cause jam phenomenon of roller. More than a few is our key check in check SKFTIMKEN bearing parts, in addition to the part of the inspection, the other poor quality such as typing, such as blur, damage, should think the defective goods, severe cases can not acceptance. 3, rust, black and pitting: the latter two are 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 of severe corrosion will make the TIMKEN bearing damaged. 4, all kinds of mechanical wounds: such as abrasion, cut and bruised, crushed, can cause bad TIMKEN 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 TIMKEN bearings after operation, will become a source of stress concentration and is expanding fast, cause the TIMKEN bearing is broken, and great influence on TIMKEN bearing life and job security. In fact, for important USES of TIMKEN bearings, TIMKEN bearing factory has been to 100% of their component parts magnetic or radiographic inspection.
