Enerpac ST-52 - Manual (Page 4)

5.0 MOUNTING SPECIFICATIONS
5.1 Mounting Threaded Body Cylinders
Threaded body cylinders can be threaded into a tapped hole, secured to the fixture using a mounting flange,
threaded into the fixture and secured with a jam nut, or mounted through a clearance hole and secured with
jam nuts. See illustrations below.
When a threaded body style swing cylinder is being installed in a fixture, the thread engagement should be no
less than the thread engagement for the standard Enerpac mounting flange. If a cylinder is being mounted
using just the lower portion of the threads, the engagement should be increased for additional support. See
table below for minimum thread engagement.
5.2 Mounting Upper and Lower Flange Cylinders
WARNING: The fixture must be capable of withstanding 350 bar (5000 psi) hydraulic working
pressure when the cylinders are manifold mounted.
