Will reflect the point of view the combination of bearing vibration measurement, NSK bearing vibration of the bearing damage is very sensitive, so, through the use of special bearing vibration measurement (frequency analyzer from flaking, creasing, corrosion, cracks, wear, etc. etc.) to measure the size of the vibration, the frequency can not infer the exception of the specific situation. The measured values due to the different conditions of use of the bearing or sensor installation location prior to each machine's measured values for analysis to determine criteria.
NSK Bearings minor stripping and other damage will be issued abnormal tone and irregular sound, measuring speaker can be distinguished, using the measured sound device, running a combination of size and sound quality of the bearing rolling sound check , played the role of prevention in advance.
If you use a hole can be measured directly the NSK bearing outer ring temperature, suitable even more bits. Under normal circumstances, bearing temperature, generally in accordance with the temperature of the bearings outside the room can be inferred from the Lubrication, suitable mounting part, abrupt bearing temperature will rise, there will be unusually high temperatures, then have to stop running, take the necessary precautions. Typically, the combination of bearing temperature increased with the operation began slowly to reach a steady state after 1-2 hours. The normal temperature of the bearing due to the heat capacity of the machine, heat dissipation, speed and load. When necessary, the use of thermal sensors can always monitor the bearing operating temperature and alarm automatically when the temperature exceeds the specified value of household or stop to prevent fuel-axis of the accident.
The rotating NSK Bearings, it should be very smooth and no abnormal sound, nor should be impurities. The combination of bearings to allow the work running for a slight sound, if sound or unusual noise or crash, showed that the bearing failure. Bearing rust treatment with anti-rust oil with a slight scent, but not the amount. The bearings clean and aromatic. Bearing fine chamfer at the junction of the horizontal surface and vertical surface, and has a black border. NSK Bearings in the normal use of the process, install the bearing parts are allowed a certain temperature, when the hand stroked institutions shell should not feel hot as normal. If the process of rolling bearings using the temperature is too high, you might consider the quality of lubricating oil to meet the requirements or deterioration, the oil viscosity is too high and other factors; or installation mechanism assembly tight, tight bearing assembly; the fragmentation of the bearing cage or rolling element.
NSK Bearings noise of many reasons, one of the bearing inner and outer rings with surface wear. Again, the lack of bearing lubrication, the formation of dry friction, and bearing broken and will produce an unusual sound. Clean to maintain the combination of bearings and lubrication is very important. Check is required prior to cleaning the surface of the machine, then remove the bearing surrounding parts. Oil seal is very fragile parts, and therefore required careful disassembly, do not use excessive force, and then carefully check the oil seal and the surrounding parts, have shown adverse symptoms, be sure to change the bad oil seal will lead to NSK Bearings damage and Yan of equipment downtime.
