Bearing heating and abnormal noise are common abnormalities in equipment operation. If not promptly investigated and dealt with, it may cause bearing locking, shaft wear and other faults, resulting in production interruption. Combining practical cases, Linqing NKFB Bearing summarizes the common causes and targeted solutions for bearing heating and abnormal noise, helping enterprises quickly solve problems.

First, preliminarily determine the degree of abnormality through temperature and sound: it is recommended to control the normal operating temperature of rolling bearings below 90 ℃, and sliding bearings below 80 ℃. If the temperature continues to rise or is accompanied by irregular noises, it is necessary to stop the machine for inspection in a timely manner. The common reasons are mainly divided into four categories: in terms of lubrication, improper use of grease, deterioration of oil or mismatched models, the need to clean the bearings and replace the appropriate grease, and control the filling amount to 1/3-1/2 of the bearing space; In terms of installation, if the clearance is too small, the coaxiality deviation or the seal friction occurs, it is necessary to readjust the installation position, correct the coaxiality, and replace the damaged seal; If impurities invade or parts are damaged, they need to be disassembled and inspected to remove impurities. If the rolling elements or retaining frames are damaged, the bearings should be replaced in a timely manner; Overloading of working conditions requires adjusting operating parameters or replacing bearing models that are suitable for heavy loads based on equipment load conditions.

In daily operation and maintenance, regular inspections and monitoring of temperature and noise changes can detect potential faults in advance. NKFB provides fault diagnosis technology services, relying on professional equipment and experience to quickly locate the root cause of problems, provide solutions, and reduce downtime losses.
