MOUNTING SPECIFICATIONS
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.
