History of Gears

Gears have been used since around 350 B.C. (2,300 years ago). Gears still retain their original form to this day. One of the reasons may be that they are rather simple in construction. Many technicians today still make an effort to improve and perfect the science of gears.

"KHK Gear World" is the site to provide the gear learners with information on gears. In addition to the introductory course for beginners, it contains some reference materials for advanced learners. It also contains a "virtual factory tour", and you can see and learn how gears are made by KHK. We encourage you to visit these pages on our corporate site and hope that you will find them useful and intriguing.
