Bearing running temperature monitoring and abnormal processing skills sharing


Monitoring the running temperature of bearings is crucial for ensuring the efficient operation of machinery and preventing potential damage. In this article, we will discuss the importance of bearing temperature monitoring and share some skills for handling abnormal temperature conditions.

1. Significance of Bearing Temperature Monitoring

Monitoring the temperature of bearings provides valuable insights into the operating conditions of machinery. An abnormal increase in temperature can indicate various issues, such as insufficient lubrication, excessive friction, misalignment, or contamination. By continuously monitoring the bearing temperature, machine operators can detect potential problems before they escalate into costly failures.

2. Temperature Measurement Methods

There are several methods to measure the temperature of bearings. One commonly used method is to employ temperature sensors installed directly on the bearing housing. These sensors transmit the temperature data to a monitoring system, allowing real-time tracking and analysis. In addition, infrared thermography is another effective technique for measuring bearing temperatures without direct contact.

3. Causes and Solutions for Abnormal Bearing Temperatures

Abnormal bearing temperatures can occur due to various reasons, and it is essential to identify the cause promptly and take appropriate action. Some common causes of abnormal temperatures include:

  • Inadequate lubrication: Insufficient lubrication can lead to increased friction and heat generation. Regular lubrication maintenance should be performed to ensure proper lubrication levels.
  • Contamination: The presence of dirt, debris, or foreign particles can hinder the smooth operation of bearings and cause temperature spikes. Implementing proper sealing mechanisms and regular cleaning can prevent contamination-related temperature issues.
  • Mechanical misalignment: Misalignment between bearings and shafts can result in uneven loading and heat buildup. It is crucial to check and correct any misalignment issues periodically.

Addressing abnormal bearing temperatures requires a systematic approach. Once the cause has been identified, appropriate solutions should be implemented. These may include replenishing lubrication, cleaning or replacing contaminated bearings, or adjusting alignment settings.

4. Importance of Regular Maintenance

Regular maintenance plays a vital role in maintaining optimal bearing temperature and prolonging the lifespan of machinery. Routine inspections, lubrication checks, and cleaning procedures should be carried out according to manufacturer guidelines. Additionally, monitoring systems should be regularly calibrated and updated to ensure accurate temperature readings.


Monitoring the running temperature of bearings is essential for preventing machinery failures and improving operational efficiency. By employing various temperature measurement methods and promptly addressing abnormal temperature conditions, operators can mitigate potential risks and optimize the performance of their machinery. Regular maintenance and adherence to best practices are crucial for ensuring the long-term reliability of bearings and the overall productivity of the equipment.
