Effect of vibration and temperature on inlet bearing

In the process of using the imported bearing, it can be said that the impact of vibration and temperature on the bearing is very big, let's first look at the impact of bearing vibration on the imported bearing.

Vibration can be said to be quite sensitive to bearing damage, peeling, indentation, rust, crack, wear and so on will be reflected in the bearing vibration measurement.Therefore, the size of vibration can be measured by using a special bearing vibration measuring device (frequency analyzer, etc.), and the specific case of abnormality cannot be inferred by frequency division.The measured values are different due to the use conditions of the bearings or the installation positions of the sensors, so it is necessary to analyze and compare the measured values of each machine before determining the judgment criteria.

We will then look at the effect of temperature on the bearing.

High temperature usually indicates that the bearing is in abnormal condition.High temperature is also harmful to bearing lubricants.Sometimes bearing overheating can be attributed to bearing lubricants.If the bearing in excess of 125℃ temperature for a long period of continuous transfer to reduce the bearing life.Causes of high temperature bearings include: insufficient or excessive lubrication, lubricants.It contains impurities, excessive load, bearing ring damage, insufficient clearance, and high friction caused by oil seal.

Therefore, continuous monitoring of bearing temperature is necessary, whether measuring the bearing itself or other important parts.If the operating conditions are unchanged, any temperature change may indicate that a fault has occurred.

The periodic measurement of bearing temperature can be made by means of a thermometer, such as the SKF digital thermometer, which can accurately measure the bearing temperature and display it in units according to the temperature of ℃ or Fahrenheit.The importance of bearings means that when they are damaged, the equipment will be stopped, so it is best for such bearings to be equipped with temperature detectors.
