Lower temperature shock on the NTN bearing life car affect the effective measures

NTN bearing make precision parts, thus a prudent attitude when use requirements accordingly, both using the high-performance bearing, if use undeserved, also cannot achieve the expected performance effect, therefore, should be paid attention to when using the auto bearing the following items: keep the imported bearing and the surrounding environment clean. Dust into the bearing even invisible to the naked eye smile, also can increase the wear of imported bearings, vibration and noise. Use should be careful when installed, do not allow the powerful punch, are not allowed to use hammer percussion bearing directly, don't allow through the transfer roller pressure. Using appropriate and accurate installation tools, use special tools as far as possible, avoid using cloth class and short fiber, things like that. To prevent rusting of imported bearings, bearing directly with the hand take cars, to fully wash hands sweat, and again after coated with high quality mineral oils, especially in the rainy season and summer to pay attention to rust. One, the influence of the vibration of bearing. In the usual use of vibration is quite sensitive to auto bearing damage, peeling, indentation, rust, crack and wear will be reflected in the NTN bearing vibration measuring. So, through the use of special bearing vibration tester ( Frequency analyzer, etc. ) Can measure the size of the vibration, through frequency points cannot deduce the abnormal situation. Measured values of bearing or sensor installation position and different using conditions, thus requiring prior to each machine is analyzed by the measured value of the determined after judgment standard. Second, the influence of temperature on the bearing. With high temperature often said bearing is in abnormal situation. High temperature is harmful to auto bearing lubricant. Sometimes overheated bearings can be classified to the bearing lubricant. If the NTN bearing in more than 125 ℃ temperature for a long time even move to reduce the bearing life. The causes of high temperature bearing 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 car bearing temperature is necessary, 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. NTN bearing temperature measured on a regular basis can use thermometer, digital thermometer, for example, can accurate measuring car bearing temperature and the constant unit in accordance with ℃ or Fahrenheit temperature display. The importance of bearing, means that when the damage cause of equipment downtime, so this type of NTN bearing should be equipped with best temperature probe.
