SPC Gas Springs,
cushioned 2486.12.
FIBRO SPC Gas Springs »Speed Control
TM
« are designed to
reduce or eliminate the sheet metal retainer bounce back
which is often caused by the increased return travel speed
in high speed presses (link drive presses).
SPC Gas Springs feature an integral return travel delay which
reduces the speed of the gas spring to 0.4 m/s over the last
30 mm of travel, allowing a soft arrival for the sheet metal
retainer.
