Peninsular’s unique and improved
cushioning system contains
advanced engineering features that ensure effective cushioning
of our high pressure metric hydraulic cylinders. Our
industry proven and tested cushioning system will usually
provide about four times the cylinder life as compared to a
cylinder that is not cushioned, in those applications
that contain stroke lengths in excess of 75 millimeters to 100
millimeters.
Because of our cushion system design,
thicker tie rod and tube diameters, a teflon backup ring
around the OD of our rod cartridge and
other important internal engineering features, our cylinders
have significantly outlasted the competition in destructive type applications.
High
pressure hydraulic cylinder adjustable cushions are internally designed
features, by each cylinder manufacturer, that prevent the
cylinder piston from slamming into the inside surface of the
end cap at the end of the extended and retracted cylinder
stroke. Our unique cushion design significantly enhances the
cushioning system, and thereby increases the efficiency of the
cushion effectiveness. By reducing the force of the impact of
the piston slamming into the cylinder end cap, cylinder tie rod and piston rod failure
due to fatigue is all but eliminated. Our adjustable cushion
design also contains a captive cushion
adjustment screw, a safety feature that prevents injury
to anyone who may be loosening the cushion adjustment screw to
control the end-of- stroke travel speed of the piston rod. The
drawing below further illustrates how the Peninsular Model IHP
high pressure metric hydraulic cylinder cushion system works.
