NSK (Nippon Seiko Kabushiki-gaisha) was founded in 1916 in Tokyo and is Japan's largest bearing manufacturer. NSK supplies bearings for automotive, industrial machinery, precision instruments, and steel production equipment. Their product range spans miniature bearings through large-bore spherical rollers. NSK part numbers generally follow ISO base designations but use distinctive suffixes — DDU for rubber contact seals, ZZ for metal shields, and CM for C3 clearance — creating a brand-specific nomenclature that requires cross-referencing to match equivalent SKF or FAG parts.
