MAN B&W NR-Series
Produced from the 1980s to the 2010s for engines in the 300-2,500 kW range with pressure ratios up to 4.5:1, NR-Series is MAN's radial classic mainstay: a massively popular single-stage radial line for medium-speed 4-stroke auxiliary and propulsion engines, valued by crew for its simple, rugged design and ease of cleaning. The -R and -S suffixes denote inboard versus outboard bearing arrangements or customized compressor trim.
