HSI has excelled in building custom high quality hydraulic cylinders since 1976. Our cylinders fill America's equipment manufacturers' needs for those projects where run-of-the-mill won't cut it. Our experienced engineering team can take a proven design and build straight from it, or take your limited details and turn it into a cylinder drawing ready for approval to build from. High strength material is used to be sure the cylinder has quality in its bones. Our skilled team of machinists and welders then take the project through the build, with attention to precise tolerances and quality procedures. The final product is assembled and tested in a way that ensures that it is 100% ready for the application it was designed for. Final painting and preparation for shipping are done with care so it arrives at the job ready for work.
