Deceleration of heavy loads and progressive adjustment

Energy capacity 210,000 in-lbs/cycle
Stroke 10.000 inch

Strong and adjustable: Also in ACE's product range of units are adjustable heavy duty industrial shock absorbers. The models from the A1½ to 3 range, which weigh between 16.6 lbs and 78.3 lbs (7.55 and 35.5 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.
