For over 90 years Kohara Gear Industry (KHK) has engaged in the production of replacement pinions. The dedication to this product has resulted in sourcing world-class equipment and training of personnel in world-class production methods.
Replacement gears are dimensionally identical substitutes for worn or damaged gears in existing machinery. KHK’s vast inventory of 27,000+ configurations means most metric gear replacements are available for immediate shipment.
Kohara Gear Industry is both ISO 9001:2015 and ISO 14001:2015 certified. Every replacement pinion 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 replacement pinions 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 replacement pinions for any application.
In addition to replacement pinions, 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 replacement pinions, we provide free resources including How To Select Gears, free gear calculation software, and free gear drafting software.
KHK’s replacement pinions are available in a wide range of modules from 0.5 to 10, covering fine pitch, medium pitch, and coarse pitch applications.
