Telescopic Cylinders

Telescopic cylinders, also known as multi-stage or telescoping cylinders, are innovative hydraulic actuators designed to offer exceptional reach and stroke length while maintaining a compact and space-saving profile. Telescopic Cylinders manufactured by HydroDyne Industries are versatile cylinders and consist of multiple nested stages that retract and extend in sequence, allowing for extended strokes and a wide range of applications in various industries. Telescopic cylinders are commonly used in scenarios where a long stroke is required, but space constraints prevent the use of traditional linear actuators.
