ACE Controls, Inc. HB 15-25-CC-P Hydraulic Damper

ACE HB-15-25 hydraulic damper delivers compact, maintenance‑free damping with a 0.59 inch (15 mm) outer body and a 0.98 inch (25 mm) stroke, providing up to 179.85 lbs of damping force in both compression and extension, and an extended length of 3.54 inches. The unit uses a 0.24 inch (6 mm) piston rod, a black anodized aluminum body, a steel wear‑resistant rod, and zinc‑plated steel end fittings, weighing about 0.151 lb, with damping adjustable by turning the rod (clockwise increases, anticlockwise decreases) and a free travel of roughly 20% of stroke. Operating from -4 °F to 176 °F and using hydraulic oil or ATF as the damping medium, this sealed, maintenance‑free damper mounts in any position and is designed for damping swinging masses, such as in conveyors and door/flap mechanisms, with a broad range of end fittings available to tailor its fit to your application. Lifetime is approximately 250,000 cycles, and a separator piston option is available to achieve zero free travel by using a separator piston and nitrogen accumulator.
