HDN 1.5 X 12 Enidine Heavy Duty Hydraulic Shock Absorber, 1.5 in Bore, 12 in Stroke

The Enidine HDN 1.5 X 12 is a heavy duty hydraulic shock absorber with a 1.5 in bore and 12 in (300 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.
