Oil pollution because of the INA bearing the cause of the high temperature and cleaning method - bearing knowledge

INA bearings because of frequent use, oil can reduce the service life of bearing, that how we can clear the oil on the INA bearing? Here to teach you a method to easily clear the oil on the INA bearings. Soft dry oil or rust cream hardening bearing, should dip in 100 ℃ ~ 200 ℃ hot oil, clamp bearing with forceps, brush with wool clean oil bearing. Soft dry oil or rust creams are heated to 100 ℃ ~ 200 ℃, melting, easily washed out of the bearing gap. Sometimes as long as bearing repeatedly shaking in the oil. The oil into crevices from. In cleaning the centripetal spherical bearing, INA bearing should be the ball, pearl frame transverse transfer from the outer ring, internal ring into hot oil, again after a short cylindrical roller bearing when cleaning roller, beads, also should be the inner ring and outer ring off. In the hot oil when cleaning, the oil temperature should not exceed 20 ℃. INA bearing temperature, generally have a bearing on the surface of the outdoor temperature can be predicted, if the use of oil hole can be directly measured INA imported bearing outer ring temperature, is more appropriate. Usually, INA bearing temperature as bearing operation began to rise slowly, 1 - After 2 hours to reach steady state. The normal temperature of bearing for machine heat capacity, heat dissipating capacity, rotational speed and load. If the appropriate lubrication, installation department, the bearing temperature will rise sharply, appear unusually high temperature, must stop at this moment, take the necessary precautions. Using thermal device can monitor the working temperature of INA bearings, and realizes temperature e. automatic alarm or stop to prevent the shaft when more than the accident. With high temperature often said INA bearings is in abnormal situation. High temperature also harmful to the bearing lubricant. Sometimes overheated bearings can be classified to the bearing lubricant. If INA bearings in more than 125 ℃ temperature for a long time even move to reduce the bearing life. The causes of high temperature INA bearings include: lubrication inadequate or excessive lubrication, the lubricant. Contains impurities, heavy load, bearing damage, clearance, high friction and oil seal and so on. So the continuous monitoring INA bearing temperature is necessary, INA bearing whether measured bearing itself or other important parts. If it is on the basis of the operating conditions, the temperature change of any fault has occurred. INA bearing temperature measurement can be regularly with the aid of thermometer, digital thermometer, for example, can accurate bearing temperature measurement and display by ℃ or Fahrenheit units. The importance of bearing, means that when the damage cause of equipment downtime, so this type of bearings shall be equipped with best temperature probe. In just under normal circumstances, INA bearing lubrication or lubrication after there will be a natural temperature rise and the last one to two days. Usually, the working temperature over 150 ° use bearing called high temperature bearing, due to chromium bearing steel in the use of temperature over 150 °, the hardness will fell sharply, size is not stable, the bearing can't work normally. So for the working temperature at 150 ° to 350 ° work under the conditions of INA bearings, if the ring and rolling body still choose ordinary high carbon chromium bearing steel manufacturing, it must be to special tempering treatment of INA bearings parts, shall generally be higher than working temperature tempering under 50 °. After tempering treatment according to the requirements of the bearing steel, can be used in normal working temperature. But after tempering hardness decreased, INA bearing life.
