HDA 3.0 X 8 Enidine Adjustable Heavy Duty Hydraulic Shock Absorber, 3.0 in Bore, 8.00 in Stroke

The Enidine HDA 3.0 X 8 is a adjustable heavy duty hydraulic shock absorber with a 3.0 in bore and 8.00 in (200 mm) stroke.

Enidine Heavy Duty Series large-bore hydraulic shock absorbers protect equipment from large impacts in applications such as automated storage and retrieval systems and overhead bridge and trolley cranes. An internal charged air/oil accumulator replaces mechanical return springs, giving a shorter overall length and reduced weight; the optional bladder accumulator (BA) allows higher cycle rates.
