The air connection takes place via the M5 coupling holes at the
side as standard. Straight or angled pneumatic screw connections
can be fitted for the air supply.
There is an alternative connection option via two M3 connections
on the base side for unlocking and locking. In this case, the side
connections must be sealed off with the two M5 locking screws
(already fitted when delivered). If this connection version is
chosen, the hose-free direct connections on the base side must
each be sealed with an O-ring. In the customer-specific attachment
flange, recessed O-ring seats are required for this.
Machine the axial sealing O-ring seat according to the following
dimensions:
Ø 5.5
+ 0.1
x 0.7
+ 0.05
.
The accessory pack contains O-rings (see Assembly drawing, item
19) for sealing the bottom hose-free direct connections.
When the locked connection is used, the spring-actuated locking
procedure is actively supported with air pressure. If the locked
connection is not used, the relevant side of the piston must be
able to ventilate.
In the dynamic work process, SCHUNK always recommends
switching on the locked connection.
