Analysis of Causes and Solutions for Temperature Rise in Spherical Roller Bearings

Source: China Bearing Network | Date: September 2, 2013

When a spherical roller bearing experiences a temperature rise, it is essential for personnel to determine whether the bearing can continue operating or if an immediate intervention is required. High temperatures can lead to serious damage, so identifying the root cause and taking appropriate action is crucial. Here are some common causes and solutions for bearing temperature rise: 1. **Poor Device Quality**: If the equipment itself is of low quality, it may lead to excessive heat generation. The solution is to improve the overall quality of the device and ensure proper maintenance. 2. **Too Tight Belt**: A belt that is too tight can increase friction and generate heat. Adjusting the belt tension to the correct level can help reduce this issue. 3. **Use of Standard Accuracy Bearings**: It is recommended to use high-quality bearings such as TIMKEN bearings that meet standard accuracy specifications to avoid unnecessary heat buildup. 4. **Improper Surface Treatment**: Poor surface finish or inadequate lubrication can also contribute to overheating. Using high-quality materials and ensuring proper cleanliness can prevent this problem. 5. **Damaged Rolling Bearings**: If the bearing is damaged, it must be replaced immediately to avoid further damage to the system. 6. **Misalignment of Spindle or Housing**: If the spindle is bent or the housing hole is not aligned with the bearing, it can cause uneven loading and overheating. Correcting the alignment is necessary. 7. **Incorrect Installation Orientation**: Incorrect installation can cause axial forces that lead to overheating. Ensure the bearing is installed properly, with the inner and outer rings correctly aligned. 8. **Excessive Axial Force**: If the axial force is too high, it can cause the bearing to overheat. Adjusting the sealing ring gap and clearing any obstructions can help reduce this. 9. **Inner Ring Damage**: If the inner ring is damaged, it should be replaced along with any worn components. Checking the balance hole diameter and impeller static balance value is also important. If you notice that your spherical roller bearing is running excessively hot, stop the equipment immediately and investigate the cause. Follow the above steps to address the issue, but keep in mind that each cause requires a specific solution. It's always best to consult a technician to ensure the problem is fully resolved. **Related Bearing Knowledge** - SKF Bearing: Analysis of Clearance Impact on Bearing Life in Full-Bearing Pumps - Common Issues and Solutions in FAG Bearing Applications - Understanding High Temperatures in SKF Bearings This article was originally published on China Bearing Network.
