Large Stage Cylinders

When your job demands a particularly long stroke from a shorter retracted length, HSI Corporation can design and manufacture a high quality, custom telescopic cylinder to precisely fit your need. Telescopes take expert engineering to ensure an exact fit into your job. They require expert material machining to make certain each part works precisely as designed without failure. Multi-stage cylinders need comprehensive testing to ensure many reliable cycles in the field. HSI's 40 years of experience ensures our customers get exactly what they need in a high quality telescopic hydraulic cylinder.
