HDN 3.0 X 2 BA Enidine Heavy Duty Hydraulic Shock Absorber, 3.0 in Bore, 2.00 in Stroke, Bladder Accumulator

The Enidine HDN 3.0 X 2 BA is a heavy duty hydraulic shock absorber with a 3.0 in bore and 2.00 in (50.0 mm) stroke, with bladder accumulator (BA).

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.
