15.2 General description of gas springs

GAS SPRINGS
The gas springs are developed and produced based on the long experience in the
nitrogen gas spring research and development.
We understand that the final quality of our product is the individual quality of all
its parts, and we therefore painstakingly check each and every one of them.
All the components are subjected to visual and dimensional inspection
prior to assembly.
100 % of the gas springs are subjected to dynamic and static gas-proof testing.
All STRACK gas springs, thanks to their design, admit maintenance in a quick and
simple manner.
Most STRACK gas springs have a one-piece construction in all their components,
thus eliminating risks of breakage due to material fatigue and therefore also
eliminating possible leakage points.
All STRACK gas springs are supplied with a quality certificate.
COMPONENT CHARACTERISTICS
Body
Developed in one piece up to strokes of 125 mm. In higher strokes they have a
tubular construction with a welded lid. As a difference with other brands, STRACK
incorporates a threaded joint between the two elements that eliminates the
possible fatigue factor in the weld bead.
Stem
Fatigue-resistant steels are employed, which have specific treatments that ensure
a long useful life. STRACK offers the maximum quality MICROFINISH on the surface
of all its stems, thus ensuring a longer service life by reducing friction and wear
and tear in the seals..
Bushing
It incorporates a scraper, an element that avoids the entrance of filth. All bushings
are designeavoiding a metal-to-metal contact, recurring to self-lubricating guiding
elements. Reference to gastightness, specific seals are used, which have been
painstakingly tested and which offer a high working yield even near their
maximum limits of use.
