5 Major Causes Of Excessive Bearing Temperature And Treatment Measures

3 Roller Bending Machine

Plate bending machine is a general equipment for bending metal sheets into cylindrical, arc-shaped or other shaped workpieces. According to the principle of three points forming a circle, the relative position changes and rotational motion of the workpiece are used to cause continuous plastic deformation of the plate to obtain a workpiece of a predetermined shape. This product is widely used in boilers, shipbuilding, petroleum, woodworking, metal structures and other machinery manufacturing industries.

Plate rolling machines are essential tools in various industries, enabling the shaping of metal sheets and plates. However, one common issue operators encounter during their operation is excessively high bearing temperatures.

Top 5 Common Causes of Excessively High Bearing Temperature

  1. Insufficient Lubrication: Inadequate lubrication is a primary factor leading to high bearing temperatures. Without proper lubrication, friction between bearing components increases, causing heat buildup.
  2. Overloading: Excessive workloads can strain the bearings, leading to higher temperatures. Overloading the machine with materials beyond its capacity is a common cause of bearing overheating.
  3. Misalignment: Misalignment of the plate rolling machine’s components can put uneven pressure on the bearings, leading to abnormal heat generation.
  4. Contaminants and Debris: The presence of contaminants like dirt, metal shavings, or moisture in the bearing can disrupt proper functioning, resulting in elevated temperatures.
  5. Poor Maintenance: Neglecting routine maintenance and inspection can allow problems to go unnoticed, contributing to increased bearing temperatures over time.

Solutions to Overcome High Bearing Temperature

  1. Lubrication Maintenance : Regularly check and maintain the lubrication system to ensure it is functioning correctly. Use high-quality lubricants suitable for the machine’s specifications and follow recommended lubrication intervals.
  2. Load Monitoring : Implement load monitoring systems to prevent overloading. Set machine limits within the manufacturer’s recommendations and provide clear guidelines to operators.
  3. Alignment Checks : Conduct alignment checks to ensure all machine components are properly aligned. Address any misalignment issues promptly to prevent excess heat generation.
  4. Contaminant Prevention : Institute strict cleanliness protocols in the machine’s vicinity. Install effective dust and debris collection systems to minimize contaminants entering the bearing area.
  5. Scheduled Maintenance : Create a comprehensive maintenance schedule that includes regular inspections, cleaning, and replacement of worn components. A well-maintained machine is less likely to experience overheating issues.

Comprehensive Approach to Preventing High Bearing Temperature

To ensure the effectiveness of these solutions, it’s essential to take a comprehensive approach to address high bearing temperatures. This involves integrating these solutions into a well-structured maintenance and operational plan that considers various aspects.

Implementing these strategies as part of a holistic approach ensures that bearing temperature issues are proactively addressed and minimized, promoting longer machine life and enhanced operational efficiency.


Excessively high bearing temperatures in plate rolling machines can lead to costly downtime and equipment damage. By understanding the root causes and implementing a comprehensive approach that includes regular maintenance, load monitoring, and alignment checks, operators can mitigate this problem and ensure the smooth operation of their machines.

Properly maintained machines with optimized bearing temperature levels not only enhance productivity but also extend the equipment’s lifespan, ultimately benefiting the bottom line of businesses in various industries.
