TIMKEN bearing vibration led to common causes of abnormal temperature

TIMKEN bearing often have customers reflect the process of bearing vibration temperature is abnormal. According to bearing technical explanation of the group led to the factor has the following several points: General bearing temperature rise as the TIMKEN bearing speed increases. And hours after temperatures reach a steady and stable operation of 1-2. Bearing temperature main determining factors are many, such as speed, lubricants, loads intrusion of foreign bodies and other reasons. If you find the above situation must be stopped, to take the necessary checks. (Note: under normal circumstances, after in the lubrication of the bearing or lubrication will have natural temperatures rise and last for one or two days.　　）
Customers are advised to monitor bearing temperatures at any time using the thermal. TIMKEN bearings in more than 125 ℃ temperature long-term continuous transfers reduce bearing life. Cause of the TIMKEN bearing high temperature including: lubrication is insufficient or excessive lubrication, lubricant. Contains impurities, excessive load, k ring bearing loss, insufficient clearances, and so on. If not found and disposed of in a timely manner can cause bearing scrap. Therefore the continuity of the TIMKEN bearing temperature monitoring is necessary, whether measured TIMKEN bearing itself or other important parts. If operating conditions do not change case, any temperature changes may have occurred at fault.
TIMKEN bearings if abnormal vibrations in the running and is easy to produce damage. Specifically fretting damage, cracks, indentation damage phenomena such as damage, abnormal wear. So by bearing vibration Measurer to measure the size of the vibration, the measured value for TIMKEN bearings use conditions or different sensors such as installation location, we recommend that customers with the prior record numerical machine functioning to facilitate comparative analysis.
