ACE Stoßdämpfer GmbH

Piston tube design for maximum energy absorption

Self-Compensating, Piston Tube Technology
Energy capacity 89 in-lbs/Cycle to 274 in-lbs/Cycle
Stroke 0.32 in to 0.47 in

Soft damping, but enormous capacity: The SC²25 to SC²190 series of soft contact absorbers ranges from an M10 to M14 thread size and covers effective weight ranges of 2.2 to 3,400 lbs (1 kg to 1,550 kg). All models are characterized by high energy absorption and unite piston tube technology with the diaphragm seal perfected by ACE. This enables direct installation for end position damping in pneumatic cylinders at 72 to 102 psi (5 to 7 bar) or applications where deceleration needs to take place close to the pivot point.

They are maintenance-free, have an integrated positive stop and are mountable in any position. The addition of a side load adapter allows for impact angles of up to 25°. These dampers offer soft contact deceleration where initial impact reaction forces are very low, with the advantages of self-compensation to react to changing energy conditions, without adjustment.

Thanks to their robust design and their durability, these miniature shock absorbers can be used for a wide range of applications. Designers mainly use them for pick and place systems, pneumatic rotary modules and in automation applications.
