How Nabtesco and NSK differ
Both companies are headquartered in Tokyo — Nabtesco in Chiyoda-ku, NSK in Shinagawa-ku — yet they equip different parts of a machine: Nabtesco makes RV precision reduction gears and compact reducers, while NSK supplies ball screws and NSK Linear Guides plus Megatorque Motor direct-drive motors. Their corporate shapes differ just as sharply. Nabtesco was formed on September 29, 2003, by the integration of Teijin Seiki and NABCO and counts 51 overseas consolidated subsidiaries, whereas NSK dates to 1916 and employs 26,278 people. Scale adds another contrast: Nabtesco counts 8,472 employees, lists on the Tokyo Stock Exchange under ticker 6268 and keeps 15 consolidated subsidiaries in Japan alongside the overseas network, while NSK, established on November 8, 1916, is the older and larger house. Their product gravity differs too: Nabtesco stays inside drivetrain and motors with its reduction gears, whereas NSK's range also spans bearings alongside the screws, guides and direct-drive motors, so a buyer meets Nabtesco at one stage of a machine and NSK at several. The choice is therefore between a focused reduction-gear maker formed by merger in 2003 and a century-old generalist whose catalogue reaches well beyond gearing.
