JAPAN NTN Bearing

At the end of the decade, Toyo created a marketing division called NTN Sales, at the same time, becoming one of the five most prominent bearing manufacturers in Japan, alongside Koyo Seiko, Nippon Seiko, Asahi Seiko and Fujikoshi Kozai. They, along with the other four aforementioned companies held over 75% of that country's bearing market the following year. Three years later, in 1954, NTN Sales received the Deming Prize for statistical quality control while continuing to diversify its product offering. In 1956, the company started to manufacture expansion compensating bearings.

Due to the incredible growth that Toyo underwent, the organization decentralized by creating subsidiaries to oversee new products. In 1961, Toyo set up a joint venture with INA Wälzlager Schaeffler called NTN Wälzlager Europa in order to manufacture needle bearings. Toyo utilized design data from INA Wälzlager Schaeffler to make these products. They also established Kongo Bearing Company to manage the creation of pillow block bearings. One year later, Toyo founded Senyo Kosakuki Kenkyujo, a maker of ball bearing equipment. In 1963, Toyo entered into business with Hardy Spicer to produce Birfield-type constant-velocity universal joints. They also pursued business overseas by establishing NTN Bearing Corporation of America. The following year, working with GKN Transmission, the company fabricated constant-velocity joints in their home country and formed NTN Bearing-GKN while also opening a facility in Europe called NTN France. The year after that, Toyo started manufacturing oil-impregnated sintered bearings and pipe fittings.
