API Pneumatic s.r.l. DR

Series of adjustable hydraulic shock absorbers. They absorb the impact energy on the rod by the displacement of oil from one chamber to another inside the body of the cushioning. This displacement is controlled by a valve and a throttling mechanism according to the adjustment brought in. The adjustment is carried out by a nut set in the rear end. The adjusting field is from 0 to 9 and the nut is provided with a stopper grub screw. The optimal cushion is obtained: 1. If the cushion is too high at the beginning of the stroke, move the nut towards 9. 2. If the cushion is too high near the end of the stroke, move the nut towards 0. In the version without mechanical stopper the cushioning must be provided with an external one (mechanical stopper) set at 0,5 - 1 mm before the end of the stroke.
