High Rack Damper, Optimized Characteristic
Energy capacity 372,000 in-lbs/cycle
Stroke 11.81 inch

Slim with a long stroke: safety shock absorbers from the SCS38 to SCS63 product family are designed for emergency-stop applications. Strokes of up to 47.24" (1,200 mm) are possible with these maintenance-free and ready-to-install dampers. Low reaction forces result due to the large strokes.

ACE uses our proprietary custom calculation program to design each shock absorber for the specific customer application. Customization helps reduce the risk of crashes and incorrect product sizing. The characteristic curve or damping characteristics of all safety shock absorbers from ACE are individually designed to the specific customer application. The metering orifices for the applications are specially calculated and produced. These tailor-made machine elements are the ideal protection because they are less expensive than industrial shock absorbers and are effective with up to 1,000 possible full load emergency stops.

Application Examples

SCS38-63 End-position damping in 2 axes
SCS38-63 End-position damping in 2 axes
The aim was to protect a driving simulation capsule on two of its eight axes. The demands placed on a potential emergency stopper were high because it was clear that its failure would lead to massive damage to the complete construction as well as to the capsule. Even the possibility of damage to the health of the test personnel could not be ruled out and was taken into consideration in a ...
