| NTN deep groove ball bearing high temperature caused in using may be the following reasons:
1, high temperature phenomenon may be due to the bearing cooling water supply interruption. Therefore the bearing temperature rise
2, at the same time bearing related aspects will also cause temperature rise.There may be bearing lubrication oil deterioration, while the increase of moisture will cause oil acid increases, and decreases oil lubrication. Then caused bearing damage.
Handling method:
1, Check the cooling water supply situation. Make the bearing temperature drop
2, Check the bearing lubricating oil, and replace the bearing lubrication grease timely. |
