Heavy Industrial Shock Absorbers

Deceleration of heavy loads

Energy capacity 63,300 Nm/cycle
Stroke 203 mm

Powerful: The mass of these high volume absorbers are between 12.8 kg and 146 kg in weight. They complement ACE's product range of self-compensating shock absorbers. All models from this product family are designed for applications where robustness and a large energy absorption are important.

The absorbers are designed specifically for each customer application with the aid of the ACE calculation program. The risk of crashes and incorrect settings are therefore prevented The CA models can absorb up to 126,500 Nm of energy and can be used in the area of effective loads between 700 kg and 326,000 kg. The combination of being extremely solid, absorbing high levels of energy and having a large damping range makes them invaluable.

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 or other special options are available on request.
