The Influence Of Temperature On FAG Bearings

Source:  skf bearing  Time:  2020-09-10

     The high temperature often indicates that the FAG bearing is in an abnormal condition. High temperature is also harmful to the lubricant of the bearing. Sometimes FAG bearing overheating can be attributed to the lubricant of the bearing. For example, FAG Bearing 16028-C3. Long-term continuous rotation of FAG bearings at temperatures exceeding 125°C will reduce bearing life. Causes of high temperature FAG bearings include: insufficient or excessive lubrication, lubricants. Containing impurities, excessive load, FAG bearing ring damage, insufficient clearance, and high friction caused by oil seals.

 

     In the process of using FAG imported bearings, it is prone to temperature rise. When the bearing temperature rises, first judge whether it is misoperation. If it does rise, the following treatments should be done:

 

1. Check whether the cooling water pressure, water flow and piping system are normal. If the water pressure is low, it may be that the filter is clogged. When it cannot be processed in time, it can be shut down for processing. When it is confirmed that it can work, it can be put into use.

2. Check the oil pressure of the governor. If the oil pressure is low, the cooling water hydraulic valve may close.

3. Check whether the FAG bearing has abnormal noise, and check whether the FAG bearing swing is abnormal.

4. Take an oil sample to observe whether the oil color has changed, and conduct a laboratory test to see if it has deteriorated. If the deterioration is confirmed, stop the machine and replace with new oil.

5. Check whether the oil level of the oil level is normal. If it is abnormal, check whether the oil tank drain valve is closed tightly. If it has been closed tightly, oil should be refilled, if the sealing rubber gasket is leaking oil, it should be shut down for processing.Need FAG Bearing 16028-C3, click here to buy it.

 

     Vibration can be said to be quite sensitive to the damage of FAG bearings, peeling, indentation, corrosion, cracks, wear, etc. will be reflected in the FAG bearing vibration measurement. Therefore, by using a special FAG bearing vibration measuring device (frequency analyzer, etc.), the magnitude of the vibration can be measured, and the specific abnormal situation cannot be inferred through the frequency division. The measured value is different due to the use conditions of the FAG bearing or the installation position of the sensor, so it is necessary to analyze and compare the measured value of each machine in advance to determine the judgment standard.

    Let's take a look at the effect of temperature on the bearing. High temperature often indicates that FAG bearings are in abnormal conditions. High temperature is also harmful to the lubricant of the bearing. Sometimes FAG bearing overheating can be attributed to the lubricant of the bearing. Long-term continuous rotation at temperatures exceeding 125°C will reduce bearing life. Causes of high temperature FAG bearings include: insufficient or excessive lubrication, lubricants. Containing impurities, excessive load, FAG bearing ring damage, insufficient clearance, and high friction caused by oil seals.

    Therefore, it is necessary to continuously monitor the temperature of FAG bearings, whether it is to measure the FAG bearing itself or other important parts. If the operating conditions remain unchanged, any temperature change can indicate that a malfunction has occurred.

    FAG imported bearing temperature can be measured regularly with the help of a thermometer, such as a digital thermometer, which can accurately measure the bearing temperature and display it in units of ℃ or Fahrenheit. The important FAG bearing means that when it is damaged, it will cause the equipment to stop. Therefore, it is better to install a temperature detector for this type of FAG bearing.

 

 

     FAG bearing temperature rise phenomenon:

 

(1). There is an alarm bell.

(2). The mechanical failure of the water wheel on the side plate of the machine lights up, the temperature of the meter indicating the bearing temperature rises, and the signal relay operates.

(3). Thermometer plate (expansion thermometer) The black needle overlaps with the yellow needle or exceeds the yellow needle.

(4). Issue a fault signal that the bearing temperature has increased.

Reasons for the temperature rise of FAG bearings

(1). Bearing cooling water is interrupted.

(2). The oil quality is degraded, the oil itself is not clean or the oil is degraded during operation, such as the increase of the water in the oil will cause the acidity of the oil to increase, which will reduce the lubrication effect of the oil, cause the bearing bush to be corroded, and cause the bearing temperature to rise.Eric Bearing Limited provides high-quality and competitive price of FAG Bearing 6317-M-C3.

 

     Treatment of FAG bearing temperature rise:

 

When the bearing temperature rises, first judge whether it is malfunctioning. If it does rise, do the following:

(1). Check whether the cooling water pressure, water flow and piping system are normal. If the water pressure is low, it may be that the filter is clogged. If it cannot be processed in time, it can be stopped for processing. When it is confirmed that it can work, it can be put into use.

(2). Check the oil pressure of the governor. If the oil pressure is low, it may cause the cooling water hydraulic valve to close.

(3). Check whether the bearing has abnormal noise, and check whether the bearing swing is abnormal.

(4). Take an oil sample to observe whether there is any change in the oil color, and conduct a laboratory test to see whether it has deteriorated. If the deterioration is confirmed, stop the machine and replace with new oil.

(5). Check whether the oil level of the oil level is normal. If it is abnormal, check whether the oil tank drain valve is closed tightly. If it is closed tightly, oil should be refilled; if the sealing rubber gasket is leaking oil, it should be shut down for processing.

When we are using FAG bearings, if we find that the temperature is very high, we should stop the operation of the equipment quickly, find out the reason, and deal with it in accordance with the solutions provided above, but it may be due to different causes of bearing heat. Therefore, the solution is also different, so it is still necessary to deal with specific situations and complete with the help of technicians.
