According to the official history page, the origin of Oiles Industries is the encounter with an unidentified wooden bearing, described as the beginning of the history of Oiles Industries and, so to speak, the beginning of the history of oil-less bearings in Japan. In 1932, founder Kawasaki Sōzō obtained a patent for a "no-oil-supply wooden bearing manufacturing method"; in 1939 he founded the individually operated "Japan Oil-less Bearing Research Institute"; and in 1940 "Oiles" was registered as a trademark. In 1952, "Japan Oil-less Bearing Research Institute Co., Ltd." was established (capital 1 million yen), and in 1958 the company changed its trade name to "Nippon Oiles Kogyo Co., Ltd." In 1966 the trade name was changed to "Oiles Corporation"; in 1967 a head office and factory (current Fujisawa Works) was opened in Fujisawa City, Kanagawa Prefecture; in 1970 the Shiga Factory was opened in Kurito Town (now Ritto City), Shiga Prefecture; and in 1976 the first overseas local subsidiary, "Oiles America Corporation," was established in the United States. In 1989 the shares were registered with the Japan Securities Dealers Association as an over-the-counter registered stock, and in 1997 the shares were listed on the First Section of the Tokyo Stock Exchange. In 1998, "Shanghai Zirun Bearing Co., Ltd." was established as the first local subsidiary in China. In 2002 the company celebrated its 50th anniversary and established "Oiles (Thailand) co.ltd" in the Kingdom of Thailand; in 2003 it split off the building equipment business and merged it with a sales subsidiary, changing the company name to "Oiles ECO Corporation," and established "Oiles Czech Manufacturing s.r.o." in the Czech Republic; in 2005 it established "Zirun Bearing (Suzhou) Co., Ltd." in the People's Republic of China; and in 2011 it established "Oiles Self Lubricating Bearings Manufacturing Private Limited" in the Republic of India.
