INA oilless bearing running early fatigue several attention points

Of all the INA bearing premature failure cases, about 16% are caused by improper installation or improper installation method. A variety of different applications may need to machinery, installation to heat or hydraulic equipment properly and effectively without oil bearing. Select the appropriate application installation method will help you to extend the service life of bearing, reduce premature bearing failure and potential damage caused by the cost of the application. Before installation, usually bearing oil bath heating. However, this approach may be contaminated bearing, oil free caused premature bearing failure. Induction heating is the most commonly used bearing heating means, due to its controllability, efficiency and safety are high. INA imported bearing induction heater standard of application development. Bearing induction heater has many functions, help to prevent bearing damage the heating process. Specific use, in fact, if each has taken a sufficient number of bearing life test, to verify whether is suitable for the selected bearing on the economy of time and labor, as a result, the bearing life test is necessary or important in most cases, before use, and the calculation method of a standard to estimate INA bearing life of life, have enough reliability level. Bearing maintenance and judgment: to determine whether can be used to check after cleaning INA bearings remove bearing. Check the raceway, raceway, surface state, cage wear and oilless bearing clearance and to increase the dimension precision, has not damage, abnormal. Non separation of small ball bearings, inner ring, with one hand support level, rotate the outer ring to confirm smoothly. Separation of tapered roller bearings and bearing, rolling your body, the outer ring raceway surface inspection. Large bearings, because they can't rotate with the hand, pay attention to check the raceway of roller and cage, metope, such as the appearance, the higher the importance of bearing, check more carefully. When the detection of rivet head main observation is there a link between slanting, easing the welding position is not correct. The welding quality. Welding point is too small, do you have any welding or welding, solid ball card caused problems. In the process of bearing test need to pay special attention to. There are also some problems needing attention. Here to share with you many years of experience, in the local bearing detection. Oilless bearing on the environment of the first check should be in the light environment, it is the best astigmatism, in order to better INA bearings, was observed on the surface appearance and no crack and other anomalies. Such as cloud of mechanical wear and scratches, touch pressure in the process of bearing equipment can lead to shift, and result in poor equipment location, lead to the shape of the bearing flat load and stress concentration, reduce precision and service life.
