The bearing solutions provided by NSK for use in petrochemical applications are designed to address the demanding and hostile environments where pumps and compressors are used, and are routinely exposed to heat, chemicals, oils and gases, including refrigerants and ammonia gas.
The ranges available include the EM/EW cylindrical roller and HPS series of angular contact bearings. The bearings are designed to provide support for the helical rotors used in gas and air compressors, offering higher levels of heat tolerance, chemical stability and increased load carrying capacity.
In both types of bearings, substantial improvements in load capacity have been achieved. Basic dynamic load rating has been improved on the cylindrical roller bearings by as much as 30%, and on the HPS angular contact bearings by a maximum of 20% - when compared to conventional bearing types. The result is said to be an improvement in fatigue life for both types of bearings, enabling users to benefit from longer trouble-free operation and extended intervals between overhauls.
Substantial performance improvements are also provided on centrifugal pumps with the company
