FAQs

What is the module?

A module is expressed as d/N which is the pitch diameter divided by the number of teeth. This explains the size of the gear or qualifies the unit size of a gear based on the number of teeth. Use this parameter to conclude if the gear is compatible.

Note

SSN type gears come with M4 grub screws fitted.
SSN10/10B and SSN10/12B are hobbed type pinions with cutter runout after the 5 mm gear face width.
