Description
<p><strong>Overview</strong></p>
<p>The Enidine HDA Series adjustable shock absorber is a heavy‑duty, large‑bore hydraulic damper designed to protect equipment against high‑energy impacts. This 200 mm stroke model with front‑flange mounting and a built‑in safety cable provides flexible energy absorption for industrial applications where the impact energy and velocity may vary. By simply turning the adjustment knob, the damping force can be changed, allowing the same unit to accommodate a wide range of conditions【121622805966175†L532-L538】.</p>
<p><strong>Construction and Performance</strong></p>
<p>The HDA range uses environmentally friendly materials and fluids and incorporates an internal air/oil accumulator instead of a return spring to reduce length and weight【802382697475917†L34-L58】. Its adjustable design lets the operator fine‑tune the deceleration and lock the numbered setting for repeatable performance【121622805966175†L560-L563】. An internal orifice design delivers smooth deceleration with efficient damping characteristics and the lowest reaction forces【121622805966175†L560-L565】. Threaded cylinders increase surface area for heat dissipation and provide versatile mounting options【121622805966175†L567-L568】. Optional fluids and seal packages expand the operating temperature range from 15 °F to 180 °F to –30 °F to 210 °F【121622805966175†L570-L571】. Because the unit is fully field‑repairable and meets OSHA, AISE, CMAA, DIN and FEM safety specifications【802382697475917†L34-L58】, it offers long service life and easy maintenance.</p>
