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

Part of NSK's SPACEA" Series of bearings for special environments.NSK's bearings for vacuum environments utilize a special self-lubricating
MoS2-based material to extend operating life by as much as ten times overconventional bearings.
NSK's vacuum bearinas are best suited for semiconductor manufacturing
NSK vacuum bearing is a special working condition bearing produced by NSK company, which is mainly used for equipment working in vacuum environment. NSK vacuum bearings are mainly used in various vacuum devices such as space technology, X-ray tube, radar multi-control tube, high-power agility variable-frequency magnetron and so on. These bearings need to operate at ambient vacuum higher than 1.33Pa, so there are special requirements for materials and manufacturing processes .

Features and uses
NSK vacuum bearings usually have the following characteristics:

high vacuum : can work stably in high vacuum environment, vacuum higher than 1.33Pa.
corrosion resistance : suitable for corrosive environment, to ensure long-term stable operation in high vacuum and corrosive gases.
High temperature tolerance : Some models can withstand high temperature environment to ensure that they can still work normally at high temperatures.
non-magnetic : Suitable for occasions where non-magnetic materials are required to ensure that they will not interfere with the surrounding magnetic field.
Application field
NSK vacuum bearings are widely used in the following fields:

space technology : high vacuum environment for satellites, spacecraft and other equipment.
medical equipment : such as X-ray tube, radar multi-control, etc., to ensure the accuracy and stability of the equipment.
industrial application : industrial equipment such as high-power agility variable-frequency magnetron to improve work efficiency and reliability.
