6311-H-T35D Ultra-Low Temperature Bearing for Liquid Oxygen Pump

LNG (Liquefied Natural Gas) pumps are used for receiving and discharging LNG to road tankers and storage tanks. For these applications the bearing operating conditions are very tough, as the temperature can reach -162°C, and the bearing must run without external lubrication. MONTON has designed a new bearing, LNG Pump Bearings, to cope with these demanding performance requirements.

LNG pump bearings including:

1.Angular contact ball bearings

2.Deep groove ball bearings

3.Cylindrical roller bearings

Operating Conditions:
› Speed: 1160 rpm – 3600 rpm
› Gas temperature: –196° C up to 0° C
› Mainly axial load
› Very poor lubrication
