Electromagnetic clutches were developed in the late 1950s. In the early 1960s, air-conditioning clutches were developed and in the late 1960s, micro clutches were developed for office automation equipment. In the 1970s, 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 1980s, the spring applied brake line was developed along with the permanent magnet slip clutches. In the 1990s Ogura continued to automate their manufacturing facilities to lower their production costs. New models of clutches were also developed for industrial customers. These included the OPL, PHT, and MIC microclutches for use in paper transport drives and office automation equipment. New models of mobile and lawn and garden clutches were also developed to handle the ever increasing horsepower ranges in those markets. In the first half of the 2000 decade new manufacturing plants have been opened in the US and China to supply the demand of these markets.
