NSK Europe, the European arm of Japanese bearing producer NSK, has developed deep groove ball bearings that do not require external lubrication for use in submersible pumps handling cryogenic gases such as hydrogen and LNG.
NSK has developed special shaft bearings with a cage made from self-lubricating fluoroplastic for submersible pumps that handle cryogenic gases and liquids.
The stainless-steel bearings with a cage made of self-lubricating fluoroplastic are seeing rising adoption in submersible pumps as a rising variety of initiatives promote using hydrogen as an power source. These tasks often use particular submersible pumps that can reliably pump gaseous and liquid media in steady or intermittent operation at low temperatures all the means down to round -200°C.
In such pumps, the double bearing of the pump shaft is a crucial design element. pressure gauge หน้าปัด 4 นิ้ว is essential, and no lubricant can be utilized aside from the media washing across the bearing. However, this locations powerful calls for on the fabric pairing.
So NSK has developed a collection of deep groove ball bearings specifically for these distinctive operating situations, and a variety of other key design options present differentiation from typical pump bearings. For instance, the inside and outer rings are made from a stainless-steel tailored to the particular requirements of rolling bearings.
A secure cage that occupies the whole internal quantity of the bearing offers steerage for the rolling elements (also made from stainless steel), while the cage materials, a self-lubricating fluoroplastic, ensures low friction operating of the bearing with out exterior lubrication. In addition, the high-performance fluoroplastic is extraordinarily wear-resistant and offers good low-temperature properties at speeds up to 3600 rpm. The cage has a two-piece design, with the two halves joined by stainless-steel rivets.
The NSK bearings can be found in numerous sizes (shaft diameter 30–100 mm) and are designed to be used in both bigger hydrogen pumping services and decentralised applications, such as hydrogen filling stations.
