What if the crane bearing overheats?

As an important part of crane, the use and maintenance of bearing are also concerned by everyone. If the crane bearing is often overheated during use, how should we solve the overheated condition of the crane?

First of all, let's talk about the causes of heavy bearing overheating.

Crane bearings need constant rotation and friction under working conditions, and the principle of friction heat generation has long been a well-known physical knowledge. Therefore, the overheating of lifting bearing is mostly caused by the heat accumulation caused by its rapid rotation.

Therefore, we need to take appropriate measures to solve or improve the problem of overheating of lifting bearings.

A common method is to conduct heat dissipation design or cooling treatment for the lifting bearing, so that when the lifting bearing is heated up, it can be cooled or cooled simultaneously, so as to avoid overheating of the lifting bearing.

In view of the fine and small size of the lifting bearing parts themselves, the cooling method is easier to realize than the heat dissipation design method. The cooling results of the lifting bearing can be achieved by introducing cooling water into the bearing bush or directly supplemented by cooling water circulation.
