Japan NOK - a pioneer and devotee of the world's sealing industry. NOK Co., Ltd. was established in 1939. It is the earliest company in Japan to produce oil seals. It is one of the largest sealing product manufacturers in the world. It is a Japanese stock listed company with annual sales of RMB 25-30 billion. NOK products occupy more than 70% of the market in Japan and more than 50% of the market in other countries.
NOK's technology research in the world's sealing industry has always maintained an advanced level. Most of the research has not been conducted by previous generations, turning many "impossible" into "possible". In the late 1950s, the "lubrication theory of oil seals and seals" was first created to explain the sealing mechanism theoretically. The high-temperature and high-pressure polyurethane synthetic rubber developed in the 1960s was awarded the world patent.
NOK has developed a large number of high-quality sealing products (up to 130,000) with its unique rubber material formula, and can be equipped with different sealing products under different working conditions, pressure, temperature, speed and media levels.
