Heavy Industrial Shock Absorbers
A11/2X61/2F

Deceleration of heavy loads and progressive adjustment

Adjustable

Strong and adjustable: Also in ACE's range of units ares heavy duty industrial shock absorbers, which can be adjusted. The models from the A1 1/2 to A3 range, which weigh between 7.55 kg and 48 kg (16.6 lbs and 105.8 lbs), are extremely robust, ready-to-install hydraulic machine elements 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 required data. The A models cover a range of effective loads from 0.3 kg to 204,000 kg (0.66 lbs to 449,743 lbs) and can absorb up to 44,000 Nm (389,433 in-lbs) energy.
