Home | About KHK | History of KHK | Photo Album

Company History - from an old photographic album(No.7)

Our first catalog was issued in 1957. It was written on tracing paper. The items listed were mostly in inch sizes.

Our early Stock Gear print catalogs were issued from 1958 to 1960, wherein we can see our KHK logo was already in use. We still deal in some of the metric worm gears listed on the old catalog, which means that these worm gears have been used by our customers for nearly half a century.

The metric miter gears with 20 degree pressure angle (item S45C), appearing on the catalog as new product, are one of our main products today.

Catalogs were hand-written and printed in cyanotype.


Our first print catalog


The miter gears made of S45C then produced still hold the exactly same dimensions today.


KHK bevel gears were used as a machine element for open and shut device of floodgates, machine tools, and farm machines.


Some of the worm gears then produced still hold the same dimensions today.


Replacing the half-a-century old gear with a new gear is possible if the gear used is the stock


We tried at times to persuade our customers to act as our sales agent. Some of such customers grew into our current sales representatives.
