64 64 Issue7.2014 Specifications subject to change SafetyShockAbsorbersSCS38 toSCS63 ​ Function: In thenormal “ready” condition thepiston rod is fully extended.When the impact load strikes the absorber thehydraulicoil behind thepiston is forcedout through a series ofmeteringorifices. Thenumber ofmeteringorifices in action reduces proportionally though the stroke and the load velocity is thereby smoothly reduced to zero. The internal pressure and thus the reaction force (Q) remains constant throughout theentire stroke length. Thedisplacedoil is stored in the bladder accumulator. The integratedgas chamber, containing low pressurenitrogen, provides the return force to reset the rod to its ex- tendedposition and functions as an accumulator for thehydraulicoil displacedduring theoperation. Material: Steel bodywithblack oxide finish. Piston rodhard chrome plated. EnergycapacityE 3 : Atmax. side load angledonot exceed80%of ratedmax. energy capacity below. Fillingpressure: Approx. 29psi Operating temperature range: 10 °F to150 °F On request: Integrated rod sensor for indicating the completeextension of thepiston rod. Typenormally closedor normally open, optionPNP or NPN switch. Increepspeed: It is possible to useup to approx. 60%of thebuffer stroke. In creep speed conditions the shock absorber providesminimal resistance and there is nobraking effect. ACEsafetyshockabsorbers are self- contained andmaintenance-free. They are designed for emergency deceleration and are aneconomic alternative to industrial shock absorbers. The SCSseries units are available withoperating strokes up to47.24" and are specially orificed toprovide a smooth constant deceleration throughout their entire stroke length. The internal hydraulicpressure and thus thebraking force, ismaintained at a con- stant safe level tobring the fastmoving load gently to rest in anemergency. Applications specially include conveyor systems, automated storage, cranes andheavymachines. Optional rodsensor available for indicating thecomplete extensionof thepiston rod.
