Custom Cylinders

The cylinder shown in the attached photos are three stage double-acting cylinder with a 20 inch bore main tube and a 6 inch diameter rod. It has a stroke of 19 feet and develops 108 tons of push force in the final stage at a system pressure of 2,500 psi.

This telescopic cylinder is double-acting, and both the extend and retract hydraulic ports are located on the fixed main tube. Most telescopic cylinders require a hydraulic port connection on the moving rod-end, or need double-walled tubing or complicated sliding “trombone” tube assemblies inside the cylinder for the retract function. The unique design of the Ventura Hydraulics & Machine Works telescopic cylinder eliminates all these complications, making the cylinder more robust through its simplified design with fewer moving parts.
