For sale is a Double acting Hydraulic Cylinder 3.39 OD by 27 inches long. 1.5 inch diameter ram. Very long double acting cylinder. I took it off a special built hydraulic press, that I took apart to get the hydraulic power unit. I personally saw this cylinder in action, it worked great and did not leak. Huge stroke (not sure exactly how long, but cylinder is 27 inches). Double acting, so it powers on both directions. Great for log splitter.
