For over 90 years Kohara Gear Industry (KHK) has engaged in the production of corrosion-resistant gearboxes. The dedication to this product has resulted in sourcing world-class equipment and training of personnel in world-class production methods.
Corrosion-resistant gears are manufactured from stainless steel, bronze, brass, aluminum bronze, and engineering plastics that withstand chemical exposure, saltwater environments, and washdown conditions without degradation.
Kohara Gear Industry is both ISO 9001:2015 and ISO 14001:2015 certified. Every corrosion-resistant gearboxe produced by KHK undergoes rigorous quality control including material analysis, dimensional verification, and performance testing.
With the largest selection of standardized metric gears in North America — over 27,000 configurations — KHK USA’s team of professionals look forward to assisting you with all your corrosion-resistant gearboxes needs.
Metric gears use the module system (designated by “m”) to define tooth size, as opposed to the diametral pitch (DP) system common in inch-based gearing. Module equals the pitch diameter divided by the number of teeth, expressed in millimeters. KHK USA provides the most comprehensive selection of stock metric gears in North America, making it easy to source corrosion-resistant gearboxes for any application.
In addition to corrosion-resistant gearboxes, KHK USA offers the full range of metric gear products: spur gears, helical gears, internal gears, miter gears, bevel gears, screw gears, inch gears, worm gears, gearboxes, CP racks & pinions, racks, and other products.
Because we are the largest and best source for corrosion-resistant gearboxes, we provide free resources including How To Select Gears, free gear calculation software, and free gear drafting software.
KHK’s corrosion-resistant gearboxes are available in a wide range of modules from 0.5 to 10, covering fine pitch, medium pitch, and coarse pitch applications.
