- Serrations

There are two major types of Serrations used in industry, Straight Sided Serrations and Involute Serrations.

Straight Sided Serrations

These Serrations are of 90 degree form and are produced on English shaft sizes ranging from 1/4" to 6" diameter. These are used for closer fits than involute splines.


Involute Serrations

Involute Serrations are involute splines with a higher pressure angle. Again these are used for close fits and have an economic advantage in that for the same pitch the tooling can cut any number of teeth.
