What are the reasons for excessive temperature during bearing operation? What are the preventive measures?
Excessive temperatures during bearing operation can be caused by a variety of factors, the most common of which is insufficient lubrication, which causes increased friction and heat generation between the bearing surfaces; high operating speeds or heavy loads increase friction and also cause temperature increases; poor alignment or incorrect installation can also cause overheating; high ambient temperatures, poor ventilation or excessive dust and debris contamination can affect the cooling efficiency and performance of the bearing, making the problem worse. Preventive measures are proper lubrication, ensuring adequate and correct lubrication to reduce friction and heat build-up; checking and correcting bearing alignment to avoid uneven load distribution, which causes excessive friction and heat; selecting bearings designed to handle the expected load and speed conditions without generating excessive heat; and ensuring good airflow or cooling systems around the bearings to effectively dissipate heat.
