Bearing of low temperature pump bearing

Bearing and bearing under low temperature pump. Bearing in the atmosphere, the general thrust ball bearings; lower bearing for guide sliding bearing, immersed in the medium of work, and lubrication by the media.  

In order to prevent the friction heating caused by liquefied gas gasification, resulting in destruction of lubrication, must use a good self lubrication materials, such as PTFE, graphite, corrosion resistant nickel alloy, etc.. At the same time, the surface of journal axis should be treated by nitriding or surfacing
