Maintenance Manual Series PT - Cytec Zylindertechnik Gmbh

Pneumatic cylinder with tolerance locking
Function
The piston rod of the CyLock PT
is extended in the same manner
as a conventional double-action
cylinder by applying pressure to
the piston side (connection A)
and retracts by applying pressure
to the rod side of the piston face
(connection B). When the final
position is reached, the locking
system comes into action by additional
pressurising of connection
C. That means the locking slide
moves in opposite direction to
the rod ans presses the locking
segments into an annular groove
in the piston rod.
This creates a positive-locking
joint.
By means of the special conical
shape of the slide it is possible
that the piston rod can lock within
a defined tolerance range and
compensate elasticities and tolerances
in production process.

As an option, a hand held proximity switch tester is available for testing and
adjusting the 3-wire PNP switches (order-no. ST 20-122). It can be helpful
especially for the mounting of the sensors.n.

Control advice
For extending the piton rod first the connection
A and then for actuating the locking the connection
C is pressurised with Pmax 4bar.
Generation of preload
• Extend cylinder pneumatically (conn. A)
• Lock (connection C)
• Ensure strainless installation in your
application
• Turn back the piston rod by one turn out of
the core or swing bearing.
