APP ROAC H AN G LE UP T O 40 °
The robust actuator guide allows actua-
tion by slide or camshaft from all direc-
tions with an approach angle !40°.
The mechanical life depends on the
material and surface properties of the
slide and the insatallation situation in the
device. The diagram opposite is also
applicable to the 1056 and 1058 series.
