NTN deep groove ball bearing maintenance maintenance attention to four points

For as long as possible in good condition to maintain state of deep groove ball bearing was, require maintenance overhaul in order to prevent accident arrangement, to ensure the reliability of operation, improve the productivity and economy. To maintain the best conditions of mechanical operation of the corresponding operation standard, on a regular basis. Content includes monitor running status, supplement or replacement of lubricants, remove the check on a regular basis. First of all, to keep the bearing and the surrounding environment clean need not say I will know what is going on, even invisible to the naked eye of dust into the NTN bearing, also can make the bearing wear, to put it bluntly, knead no sand in the eyes, is a way! The second point, careful to use installation where you won't even that common sense all can't, if not, then don't do the deep groove ball bearings, go home and play, the most important strength is not allowed in stamping, are not allowed to use hammer percussion bearing directly, not afraid of smashed, you give up deformation, how to do, take a loss yourself, ha ha, there is not allowed to pass through body pressure. The third point, using appropriate, accurate installation tools to use a special tool, to avoid use cloth class and short fiber, things like that. Fourth, to prevent rusting of the bearings, don't use bubble NTN bearing is made of stainless steel, but also afraid of water, if not letter, you put in the water bubble, ha ha, get your bearings with your hands, to wash hands fully the sweat, and again after coated with high quality mineral oils, especially in the rainy season and summer to pay attention to rust, don't tell me the rust of be afraid of what, well, you try it yourself, and see what the result is rust! Even if a few bearing fatigue spalling in a state of anomalies and irregular, if proficiency is also possible to listen to. Use of NTN bearing vibrator, and quantitatively analyze vibration amplitude, frequency, etc, thus infer the deep groove ball bearing damage condition. But due to different bearing conditions of use and the determination of location, it is necessary to use mechanical measurements, decided to determine the benchmark. Bearing temperature after operation began to slowly rise, usually after a period of time to reach saturation. Constant temperature of the bearing due to mechanical heat capacity, heat quantity, speed and load. Bearing temperature before the saturation state and abnormal rises, consider the following pages is shown in reason, stop and take the necessary measures. Investigation of grease and lubricating oil in use to understand the status of the NTN bearing operation is effective. Of course from the moisture content, sundry, iron powder and so on to judge the grease or oil leakage, discoloration, and degradation. Believe that there is a lubricant leakage and iron powder, metal powder mixed with situations such as a foreign body, regular of leakage, deep groove ball bearings, such as temperature and vibration of quantitative observation, if think there are abnormal, early maintenance.
