Our company started manufacturing and selling mechanical seals for rotating machinery such as pumps and agitators in 1955, and in May 2020, we celebrated our 65th anniversary.

For the past 65 years, we have kept in mind our company motto, "Support service for safe and continuous operation of our customers," and currently have 10 directly managed service stations in Japan, and overseas in Shanghai and Singapore, where we provide services closely connected to our customers on a daily basis.

Our company was founded in 1955 when we succeeded in producing carbon rings, the main component of mechanical seals, domestically, and were given a certificate saying that our products were incomparable to foreign products, which were the mainstream at that time. Since then, we have acquired not only carbon technology, but also mechanical seal technology and its handling methods by accumulating training with the guidance of our customers. Today, as the only seal manufacturer in the world that develops and produces carbon in-house, we are striving to improve the performance and quality of our products, and have earned a high reputation and trust from our customers for our contribution to the optimization of their seal maintenance.

In addition to our mainstay mechanical seals for petroleum, chemical, and food plants, our products include ABC seals for powders, which are widely used to prevent contamination and as an environmental measure, cartridge masters, which are popular for building maintenance, and vacuum movable frame body frames, which are based on vacuum sealing technology. In addition, we also provide vacuum movable frame body frames that apply vacuum sealing technology. In addition, we have developed and supply porous carbon as a non-contact conveyance and adsorption pad for semiconductor wafers and liquid crystals, which require extremely delicate handling, by sharpening our carbon technology since our establishment. In this way, we are proud that our technology and products are contributing to society in a variety of unseen situations, mainly in social infrastructure.

If you explore, you will succeed.
Without forgetting this founding spirit, we will continue to hone our unique technological capabilities to meet the needs of our customers and society, and make a contribution.
