LNG Pump low temperature Bearings

Mian Bearing Codes

Feature:

Stainless steel rings

Ceramic balls

Ptfe cage

Long life

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. NSK has designed a new bearing,LNG Pump Bearings, to cope with these demanding performance requirements.

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