In real life many factors bearing, for example, temperature, vibration, etc. These are factors that affect the needle bearing, and how to prevent these factors to the impact of NTN Bearing, here to tell you about vibrationand temperature of the bearing:
One, bearing vibration
NTN Bearing vibration is sensitive to damage, such as peeling, creasing, corrosion, cracks, wear will be in bearing vibration measurement embodiment, through a special needle bearing vibration measurement instrument used (frequency analyzer) measurement of the size of the vibration frequency can not be inferred by the unusual circumstances. The measured value sensor bearings?? Conditions of the installation location is different, so prior analysis of each machine and the measured values ??to determine the standard to compare.
Second, the bearing temperature
NTN Bearing temperature, outside of the bearing chamber temperature can be inferred, can be measured directly using the bearing outer ring temperature is more appropriate.
Under normal circumstances, the needle bearing temperature began to rise slowly to run 1-2 hours to reach steady state. The heat capacity of the machine at room temperature bearings, cooling capacity, speed and load changes. Lubrication, install the appropriate department, NTN Bearing is a sudden rise in temperature, there will be unusually high temperatures, when to stop running, take the necessary precautionary measures.
