SDP63 to SDP160 Safety Shock Absorbers: Powerful Protection for Heavy-Duty Applications

The SDP63 to SDP160 safety shock absorbers from ACE are purpose-built for the toughest industrial conditions, offering reliable emergency stop functionality with high return forces thanks to integrated gas pressure accumulators. Engineered to meet the demands of crane installations, heavy machinery, and extreme load applications, this series delivers an unmatched combination of robust construction, customized damping, and low-maintenance operation.

These shock absorbers boast internal system seals that maintain full functionality even when the piston rod is exposed to dirt or minor damage. The return forces of up to 100 kN contribute to safer and more controlled performance in applications such as multiple bridge crane systems, while the large-sized piston rod bearing ensures long-term durability under heavy stress.
