Industrial Shock Absorbers

High energy absorption and robust design

Energy capacity 170 Nm/cycle
Stroke 23.2 mm

The latest damper technology: The combination of the latest sealing technology, annealed guide bearing and integrated positiv stop make these self-compensating shock absorbers from ACE'S MAGNUM range so successful. After all, users benefit from the longer service life of the products, even in the most difficult environments. A continuous outer thread and extensive accessories make their contribution to the success story of the MC33 to MC64.

High energy absorption in a compact design and a wide damping range lead to huge advantages in practice. Alongside generally more compact designs, these small yet very powerful absorbers enable full use of the machine's performance.

Damping medium Automatic Transmission Fluid (ATF)


A noise reduction of 3 dB to 7 dB is possible when using the special impact button (PP). For emergency use only applications and for continous use (with additional cooling) it is sometimes possible to exceed the published max. capacity ratings. In this case, please consult ACE.

Safety information

External materials in the surrounding area can attack the seal components and lead to a shorter service life. Please contact ACE for appropriate solution suggestions. Do not paint the shock absorbers due to heat emission.

On request

Special oils, nickel-plated, increased corrosion protection, mounting inside air cylinders or other special options are available on request.

Application Examples

MC33-64 - Emergency exit with MAGNUM dampers
MC33-64 - Emergency exit with MAGNUM dampers
MAGNUM 64150EUM industrial shock absorbers are integrated into the overall safety design for the Amsterdam metro system. In contrast to previous solutions, ACE shocks ensure rapid opening and stopping for a five-ton barrier located at the end of an emergency escape route. In this application, over 5,100 Nm of energy are able to be absorbed per stroke. Through installing shock absorbers in end ...
MC33-64 - Jada the badminton robot
MC33-64 - Jada the badminton robot
Serving a similar purpose, several ACE dampers are installed in Jada, the triple-axis, free-moving badminton robot. In order for the badminton robot to be capable of playing, it must be able to change direction in the shortest time possible. Jada is designed therefore to brake at a maximum of 30 m/s². For this task, linear modules are limited by the use of industrial shock absorbers of the ...
MC33-64 - Pipeline safety under water
MC33-64 - Pipeline safety under water
A pipeline from the rig to the well head that is as flexible as possible is considered to be a quick-disconnect connection in an emergency. Nevertheless, this connection made at the oil source on the sea floor is an Achilles heel. If the connection snaps or if it cannot be separated quickly enough during hazards such as storms, unpredictable, often serious consequences can hardly be prevented. ...
MC33-64 - Portal for machine loading and increase productivity
MC33-64 - Portal for machine loading and increase productivity
ACE industrial shock absorbers optimize portal for machine loading and increase productivity. This device driven by piston rodless pneumatic cylinders, in which two gripper slides are moving independently of each other at speeds of 2 to 2.5 m/sec., is equipped with industrial shock absorbers as brake systems. Their function is to stop a mass of 25 kg up to 540 times per hour. The model ...

Application Areas

  • linear slides
  • swivel units
  • turntables
  • portal systems
  • machines and plants
  • tool machines
  • machining centres
  • Z-axes
  • impact panels
  • handling modules
These self-compensating industrial shock absorbers are used in all areas of mechanical engineering – especially in automation and for gantries.
