What is a metric gear?

Traditionally metric means a measurement method based on meter, but when used to describe metric gears, it means the sizes of gears are based on the pitch size being detail in units called module (m). When the unit of Module is used, the pitch can be computed as the multiple of π. For example, if the module is 2, the pitch is 6.2832mm, and if the module is 3, the pitch is 9.4248mm.

The module is the unit to indicate the pitch of the gear teeth as designated by ISO standards, but there are other units such as diametral pitch (DP). However, while Module is internationally widely used, DP is still heavily used in the US. DP can be approximated to Module by the formula, Module = 25.4/DP.

As previously mentioned, gears using Module as the unit of Pitchare called Metric Gears, conversely, gears using DP as the unit of Pitch are called Imperial Gears. The major difference between metric and imperial gearing is in length units, however, while tools such as hobs and shafts, etc. differ in sizes, production processes such as teeth cutting and grinding, manufacturing equipment such as hobbing machines and AISI and SAE specified materials do not fundamentally differ between the two. While the majority of gear manufacturers in the US make Imperial Gears, KHK’s focus is on producing world-classquality metric gearing as its main product offering.
