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 429 lbs to 449,743 lbs. (195 to 204,000 kg) and can absorb up to 389,433 in-lbs. (44,000 Nm) energy.

These heavy duty, adjustable ACE industrial shock absorbers are the first choice in heavy duty applications and generally in heavy industrial maching design when the usage data has not been exactly determined.
