Understanding Metric Gears

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 medical device pinions for any application.
