Heavy Industrial Shock Absorbers
A11/2X31/2

Deceleration of heavy loads and progressive adjustment

Adjustable
Energy capacity 36,750 in-lbs/cycle
Stroke 3.50 inch

Strong and adjustable: Also in ACE's product range of units are adjustable heavy duty industrial shock absorbers. The models from the A1 1/2 to A3 range, which weigh between 16.6 lbs and 105.8 lbs (7.55 and 48 kg), are extremely robust, ready-to-install hydraulic machine components with impressively high energy absorption levels and a wide range of damping rates.

Their special aspect is the flexibility, as all the absorbers can be adjusted using a socket on the absorber base and be perfectly adapted to the application. The A models cover a range of effective weights from 0.66 lbs to 449,743 lbs. (0.3 to 204,000 kg) and can absorb up to 389,433 in-lbs. (44,000 Nm) energy.

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.
