Threaded body cylinders with piston rod thread
This cylinder construction with double acting function saves space
when built into fixture plates or into plates of plastic injection moulds.
The double-acting function makes cycledependant strokes possible when
retracting and extending the piston. The operation times can be calculated
from the possible flow rate of the power unit and the operated piston or ring
Unlike with single acting cylinders both stroke directions are power operated.
On the piston rod end the cylinders are equipped with a retractable wiper
made of NBR and an additional metal wiper.
The metal wiper prevents the penetration of chips into the soft wiper and in
this way the piston is prevented from jamming. This preventive measure
protects the seals and increases the service life of the cylinder.
