Clamp Arms
Clamp arms supplied with cylinders can be
used to full operating pressure of cylinders,
and will produce maximum clamping force.
Longer or modified clamp arms require low-
ering the maximum operation pressure so
that less clamping force is produced.
Tightening Clamp Arm to Cylinder
1. Back out the ball bearing plug located on
the side of the cylinder opposite of the
advance port. This will help to prevent possi-
ble internal damage to the cylinder while
tightening the clamp arm to the plunger.
2. Place clamp arm in vise. DO NOT place
the body of the cylinder in the holding
device.
3. Tighten the bolt holding the arm to the
cylinder.
4. Retighten the ball bearing plug.
Setting Plunger Rotation
Swing cylinders are supplied with rotation
set to clockwise. Follow steps below to
change rotation.
1. Remove plug located opposite advance
port to access plunger guide ball. Remove
ball.
2. Turn plunger until selected groove is visi-
ble. See Figure 4.
3. Replace ball, making sure it is seated in
the groove and reinstall plug.
WARNING
DO NOT exceed the values shown in Figure 2
or equipment damage and/or personal injury

Figure 2: Clamp Arm Specifications
NOTE: Maximum recommended flow
rate with standard arm is 200 cubic inch-
es per minute. When using longer clamp
arms, the flow rate should be reduced
and a V66-F flow control valve should be
used.
Figure 3: Clamp Arm Dimensions
★ For double arm clamping (DCA-2),
use half of straight pull capacity for each
side.
★★ Standard clamping arms supplied.
Longer arms indicated in chart can be
fabricated by the user. See Figure 3 for
dimensions.
