Mounting Swing Clamp
Secure swing clamp to fixture using one of
the following methods:
■ Screw threaded housing into tapped hole
(1 7/8”-16 UN).
■ Bolt cylinder down using the 4 mounting
holes in the flange. Mounting holes are 0.40”
diameter.
■ Mount in a through-hole and secure with a
locknut (P/N SC1CN).
Operation
Connection for Single Acting
Connect pressure line to 1/4”-18 NPT port in
flange.
Connections for Double Acting
1. Remove plunger return spring.
2. Connect advance line to 1/4”-18NPT lower
side port or the 1/8-27NPT bottom port. If
using the bottom port, plug the lower side
port with a 1/4”-18NPT pipe plug.
Air Removal
1. Apply low hydraulic pressure (approxi-
mately 10-20 PSI) to the system.
2. Loosen plug opposite advance port slight-
ly to allow air to escape until hydraulic fluid
appears.
3. Tighten the plug to prevent further leak-
age.
WARNING
WARNING
Figure 4: Plunger Rotation (Top View)
NEVER exceed maximum pressure rating of lowest rated component in your system. Maximum
pressure for SC-1 swing cylinder with standard clamp arm is 3000 PSI. When using custom
clamp arms over 4 inches long, the maximum pressure rating is LOWER. See Figure 2 for clamp
arm specifications. Exceeding rated pressure will result in component failure and may cause
equipment damage and/or personal injury.
If your swing cylinder requires repair work, contact a local ENERPAC authorized
service center.
NEVER operate a double-acting swing clamp unless BOTH ports are connected to the hydraulic
circuit. If one of the ports is left uncoupled, pressure will build up behind it when the swing
clamp is operated. This may lead to equipment damage and/or personal injury.
