Expanding our distribution bases to the United States and Germany

THK America, Inc.(USA)

Believing that "good technologies can be transferred across borders, and so can the satisfaction of the efficient manufacturing these technologies bring," we decided to expand our overseas business. The 1981 founding of THK America Inc. in the United States and the founding of THK Europe in Germany the following year formed the basis of our international sales network's expansion.
