As one of Japan's leading stock gear manufacturers, Kohara Gear Industry Co. Ltd. (KHK) offers a wide range of stock gear product lines, and with custom gear manufacturing technology backed by our extensive know-how, we have the flexibility to meed the varying demands of our customers. As a gear manufacturer, our greatest strength is our product lineup of both stock gears and custom gears. Today a majority of gear manufacturers and trading companies limit themselves to just one of these product types, but we have been able to establish a leading presence in the gear industry through our ability to supply both types. In general, our main product lines consist of spur gears, bevel gears, helical gears, worm gear, and rack and pinion.

The KHK gears are subdivided into 80 categories which contain more than 9000 items. They are made of 11 different types of materials, from chrome molybdenum steel, for high strength and wear applications, to carbon steel for normal use, through corrosion-resistant stainless steel and chemical-resistant and free-standing industrial plastic. KHK has expanded its existing range of modules 2, 3 and 4 to modules 5 and 6. These zippers are rectified on their faces and has several models: milled, hardened by 55 HRC induction, rectified, and cemented at 60 HRC. They are manufactured in straight and helical execution. Every day more and more companies rely on KHK for its high quality and precision gears and rack.
