Information on product safety

The solid cheek shaft is particularly suitable when a cylinder with direct intake is driven. Here, increasing the pre-compression with the correct exhaust selection leads to a significantly better filling of the cylinder over the entire speed range.

Milling artists can also drive the shaft on the housing inlet.
