Srujan Group is a trusted Telescopic Hydraulic Cylinders manufacturer and exporter in India, delivering precision-engineered telescopic hydraulic cylinders designed to provide exceptionally long stroke output from a compact retracted length making them the ideal hydraulic actuation solution for applications where installation space is severely limited but maximum extension stroke is critical. With over 3.5 decades of hydraulic system manufacturing experience, backed by ISO 9001:2015 certification, Srujan Group builds telescopic hydraulic cylinders that deliver reliable extending force, smooth staged extension, and long-term leak-free performance across demanding industrial, construction, agricultural, and material handling applications.
Telescopic hydraulic cylinders also known as multi-stage cylinders - consist of a series of nested cylindrical sleeves that extend sequentially from the largest outer sleeve to the smallest inner plunger, achieving a total stroke length of two to three times the retracted cylinder length. This unique design solves one of the most challenging problems in hydraulic system engineering - delivering maximum stroke in minimum installation space- making telescopic cylinders indispensable in tipper trucks, dump bodies, lifting platforms, and agricultural equipment where retracted height is strictly limited by body design.
Our Telescopic Hydraulic Cylinders are precision-machined from high-strength steel with tight dimensional tolerances on all bearing surfaces, seal grooves, and sleeve interfaces-ensuring smooth, consistent stage extension, leak-free sealing, and reliable performance across thousands of extension and retraction cycles in the most demanding field conditions. Each cylinder is custom-engineered to application specifications covering number of stages, extended stroke, retracted length, bore diameter, operating pressure, mounting configuration, and seal material requirements.
