.GEAR TECHNICAL DATA

We gathered various knowledge about gears into our Technical Data for our customers to properly design, select and use gears.

It contains comprehensive knowledge of gear terminology, how to use and measure gears, accuracy grade of gears, calculation formula of dimensions and strength of gears.

We hope it will be a textbook of gears for those who would like to desigh, use or study gears.
You can download both complete and separate version of each chapter from the following table.
