Hirth Serrations – a machine component that has both tradition and a future. Invented decades ago, yet still up-to-date, Hirth serrations from ITI Tooling Co. incorporate the demands of modern mechanical engineering.

This self-centering, radial face tooth connection enables you to connect shafts, discs, wheels and cranks with highest accuracy. The machine tool industry, for example, would be hard to imagine without Hirth serrations as indexing and positioning elements with highest precision.

The advantages of Hirth serrations are quite convincing:

· Light-weight design

· High-strength connections

· Wear-free transmission of high torques at small dimensions

· Dynamic forces are retained even after repeated assembly

· Less rotating mass compared to flange connections

· High concentricity precision and very low radial run-out

· High operating safety
