Jiangsu Haifa Machinery Manufacturing Co., Ltd.

In the field of low-temperature transportation, cryogenic pumps are widely used in liquid nitrogen, liquid oxygen, liquefied natural gas, air separation units, low-temperature chemical systems. the equipment operates in extreme low-temperature environments for extended periods, the bearings must not only radial and axial loads during rotor operation but also address comprehensive challenges such as low-temperature contraction, reduced lubrication performance, material embrittlement, and frequent start-stop cycles. Therefore, cryogenic pumps higher requirements on bearing material purity, wear resistance, self-lubricating properties, and impact toughness.

SKF has developed specialized deep groove ball bearings for cryogenic pump applications, utilizing high-purity stainless steel materials and paired with fluorine-free high-performance polymer materials. These bearings maintain excellent self-lubric and wear resistance even in low-temperature environments. Compared to standard bearings, this type achieves a 27% improvement in impact toughness during low-temperature tests effectively reducing risks such as low-temperaturerittlement, increased wear, and operational sticking, thereby enhancing the continuous operation capability of cryogenic pumps under complex conditions.

For cryogenic pumps, bearings are critical components for ensuring rotor system stability. SKF's specialized bearings for cryogenic pumps optimize material systems and structural designs to improve dimensional stability and operational reliability at low temperatures, reduce vibration and noise, extend equipment maintenance intervals, lower the risk of unplanned downtime. This of great significance for air separation, LNG, low-temperature storage and transportation, and high-end manufacturing production lines.

During relevant technical exchanges, Dr. Qian Weihua, Vice President and Chief Technology Officer of SKF China, hosted a roundtable forum and engaged in discussions with Annika Ölme, Chief Technology and Senior Vice President of Development at SKF, and Li Haibao Procurement Director of SEW China Investment Co., Ltd., focusing on high-end equipment, supply chain resilience, and technological innovation. SKF and Northeast Asia continue to advance localized R&D and supply chain construction, achieving100% local supply delivery of specialized bearings for cryogenic pumps, providing more agile and reliable support for domestic equipment.

Overall, SKF'sogenic pump bearings not only reflect advancements in material technology and precision manufacturing but also provide crucial support for the development of cryogenic pumps toward greater environmental friendliness, reliability, and robustness. For low-temperature fluid equipment manufacturers, selecting high-reliability bearing systems is a key step in ensuring long-term stable equipment operation and enhancing overall product quality.
