Industrial Shock Absorbers
SC4550EUM-5

Piston tube design for maximum energy absorption

Self-Compensating, Piston Tube Technology
Energy capacity 680 Nm/cycle
Stroke 48.5 mm

True performers: The combination of the proven sealing technology from the MAGNUM range including membrane accumulator with the well-known piston tube technology from the SC² family makes the SC33 to 45 absorber models so strong and durable. The increase of the oil volume ensures the maximum effective weights. Short stroke lengths of 25 mm to 50 mm lead to shorter braking times in combination with a high energy absorption.

These dampers safely and reliably decelerate rotary movements without unwanted recoil effects. Assembly close to the pivot point is possible. The low impact speeds with this are managed with ease by ACE's generation of piston tubes.
