Ogura was founded in 1938 as a manufacturer of mechanical clutches for the machine tool industry. Electromagnetic clutches were developed in the late 1950's. In the early 1960's, air-conditioning clutches were developed and in the late 1960's, micro clutches were developed for office automation equipment. In the 1970's, lawn and garden clutches were developed, as well as a variety of industrial clutches and brakes such as the hysteresis and multiple disk units. In the 1980's, the spring applied brake line was developed along with the permanent magnet slip clutches.
