5. Design of the PowerMax cams
STRACK NORMA Power Max cams are produced in a high-precision manner.
The guidances which are grinded to a tight guide clearance allow highest loads. The cam units can be
equipped with the tool on the working surface. In doing so you have to consider that the force affects
in the centre of the working surface.
If you have an off-center load irregular
forces arise on the guidances and produce
an increased wear.
(See 3.1. description of the construction types)
Herefrom you can clearly read the maximal force outside the centre of activity for the x respectively the y
axis. Modifications of position which will be possible in future should be considered previously to choose a
cam size which corresponds to the force.
To be able to guarantee an equal running life, the load forces reduce, according to the position, on the
working face.
You will find detailed information in the catalogue indications concerning to your cam in the internet
