Low temperature Bearings for LNG

LNG (Liquefied Natural Gas) pumps are used for receiving and discharging LNG to road tankers and storage tanks. In this application, the bearing operating conditions are very tough, as the temperature can reach -162°C, and the bearing must run without external lubrication. we have designed  LNG Pump Bearings to cope with these demanding requirements.
