Heavy Industrial Shock Absorbers
CA3X12-4

Deceleration of heavy loads

Self-Compensating
Energy capacity 300,000 in-lbs/cycle
Stroke 12.00 inch

Powerful: The weight of these high capacity absorbers are between 28.2 lbs and 322 lbs. (12.8 and 146 kg). They complement ACE's product range of self-compensating shock absorbers. All models from this product family are designed for applications where robustness and large energy absorption are important.

ACE uses our proprietary custom calculation program to design each shock absorber for the specific customer application. Customization helps reduce the risk of crashes and incorrect product sizing. The CA models can absorb up to 1,119,620 in-lbs (126,500 Nm) of energy and can be used in the area of effective weights between 1,543 lbs and 718,707 lbs. (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. Self-compensating shock absorbers react to changing energy conditions, without adjustment.

ACE will be closed between December 24th and January 2nd. Orders placed during this period will be processed on January 2.

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.
