IKO bearing vibration of the bearing damage is very sensitive, such as spalling, indentation, rust, cracks, wear and tear and will be reflected in the bearing vibration measurement, therefore, measurable by special IKO bearing vibration measurements (frequency analyzer) the size of the vibration frequency can not infer the exception of the specific situation. The measured values ??due to different conditions of use of the bearing or sensor installation location, determine the criteria for judging prior to the measured value of each machine.
   
IKO bearing temperature, generally outside of the bearing chamber temperature can be inferred, if the hole can be measured directly imported bearing outer ring temperature, it is even more appropriate.
   
Typically, the temperature of IKO bearings with the bearing running slowly began to rise after 1-2 hours to reach steady state. IKO bearings the normal temperature of the machine's heat capacity, heat dissipation, speed and load. If the lubrication, the Ministry of the appropriate installation, IKO bearing temperature are abrupt rise, there will be unusually high temperatures, then have to stop running, take the necessary precautions.
   
IKO bearings operating temperature can be monitored, and automatic alarm or stop to prevent the burning shaft accident occurred when the temperature exceeds the specified value using the thermal sensor.
   
High temperature is often said that IKO bearings in unusual circumstances. The high temperature is also harmful to the bearing lubricant. Sometimes IKO bearings overheating can be attributed to the lubricant in the bearing. If the bearings IKO bearings life long-term transfer even lower temperature than 125 ℃. Caused by high temperature bearing the reasons include: lack of lubrication or excessive lubrication, lubricants. Containing impurities, the load is too large, bearing loss of the ring, lack of space, and oil seals produce high friction.

IKO bearings temperature continuous monitoring is necessary, whether it is measuring, IKO bearings, or other important parts. If you are under the same operating conditions, any temperature change has failed.

IKO Bearings end of the installation, in order to check the installation is correct, the operation check. Small mechanical hand rotation, to determine whether the rotation smooth. Inspection items nick, indentation caused by dysfunctional torque instability, arising due to poor installation, mount processing bad due to the clearance is too small, installation errors, and seal friction torque and so on. If there is no exception, you can start the power operation.

Large machinery can not be manually rotated so cut off the power immediately after the no-load start, idle machinery, check for vibration, noise, rotating parts in contact to confirm that no abnormality, the power operation.

Power operation, start from no-load low-speed, slowly increased to the conditions stipulated in the rated operation. Test run to check the matters, whether there is abnormal sound, IKO bearing temperature changes, lubricant leakage or discoloration. If abnormal, should be immediately discontinued operation, check the mechanical, if necessary, to remove the bearing check.

IKO bearing temperature, and can be speculated that under the external temperature of the bearing. However, the use of hole directly measuring the temperature of the bearing outer ring is more accurate. IKO bearing temperature, from the operation began gradually increased, usually 1 to 2 hours after temperature stabilization.
 
If the bearing is bad installation, the temperature will soar, and abnormal high temperature. The reason lubricant such as excessive bearing clearance is too small, poor installation, and sealing devices friction is too large. The occasion of the high-speed rotation, IKO bearings, lubrication mode select error is also the reason.

IKO bearings to turn the sound with a stethoscope and other tests have strong metal noise, abnormal sound, irregular sound description of exception. The reason for poor lubrication, poor axis or IKO bearing accuracy, bearing damage, dust and debris.

In the periodic maintenance, replacement, need to disassemble the bearings. Demolished to continue to use or need to check for investigation, demolition and installation care. Note that does not damage the bearings and parts, especially the demolition of the interference fit bearing operation is difficult at the design stage should be considered in advance to facilitate the demolition.
 
Required design demolition tool is also very important. Demolished, in accordance with the conditions of drawing research and demolition methods, the order of investigation IKO bearing, so that the demolition job carried out smoothly.
