SKF Launches Latest Condition Monitoring, Bearing and Seal Technologies at Offshore Europe 2011
SKF Microlog Analyzer AX
Also on show will be SKF's advanced hybrid cryogenic pump bearings, which offer exceptional levels of reliability and performance where moving parts are exposed to abrasive particles, corrosive gases and liquid contaminants, vibration and electric currents. SKF hybrid bearings combine specially developed ultraclean, high-nitrogen steel, which gives excellent impact toughness, high fatigue resistance and corrosion resistance, with tough rolling elements constructed from silicon nitride. By comparison with conventional bearings, the latest hybrid devices have the ability to extend bearing life by at least 600%.
Deep groove ball bearing featuring VC4444, a special variant of SKF stainless steel, as well as low-friction ceramic rolling elements.
Other bearing units on show will include mud motor bearings, designed to resist severe axial and shock loads, with a unique multi-row construction that ensures long trouble-free operating life; and magnetic bearings for electrically driven compressors, delivering a compact, almost friction-less solution that reduces maintenance, noise and the risk of gas leaks.

Similarly, the latest SKF sealing solutions have been developed to offer long and maintenance-free operating life under harsh conditions. The company can supply a wide range of seals manufactured from advanced materials, including ED-resistant thermoplastic polyurethane elastomers with a high resistance to hydrolysis at temperatures up to +90°C. Also available are seals in fluoro-rubber (FKM) and hydrogenated acrylonitrile butadiene rubber (HNBR), which resist heat, ageing, ozone and chemicals, making them ideal for use in applications where sulphur, HFD pressure fluids, sulfonated crude oil, aliphatic hydrocarbons and sour gas are encountered.
