HDC Series D/A General Purpose Cylinders
Engineering Overview & Structural Features
The HDC Series Double-Acting General Purpose Hydraulic Cylinders are precision-engineered for intensive industrial cycling, structural bridge lifting, hydraulic press operations, and heavy plant maintenance. Operating at 700 Bar (10,000 PSI) working pressure with capacities spanning from 10 to 300 Metric Tons, double-acting hydraulic return provides rapid, high-power retraction across extended strokes. Precision collar threads and base mounting holes deliver versatile fixture mounting, while internal safety relief valves safeguard against retract-circuit over-pressurization.
Structural Features & Engineering Advantages
Retract-Side Safety Relief Valve
An internal safety relief valve built into the retract circuit automatically vents unexpected backpressure if return lines are accidentally disconnected or obstructed, preventing hazardous cylinder burst.
Hardened Alloy Steel Guide Ring
Full-thrust alloy steel stop and guide ring positively halts the piston at maximum stroke while resisting severe lateral side-load forces to prevent bore galling and piston cocking.
Industrial U-Cup Sealing System
Heavy-duty polyurethane U-cup dynamic seals with specialized anti-extrusion backup rings withstand continuous 700 Bar pressure cycling, guaranteeing zero hydraulic leakage and extended service longevity.
Hardened & Hard-Chromed Piston Rod
Precision-ground high-strength alloy steel piston rod receives hard industrial chrome plating, delivering ultimate defense against mechanical scratching, corrosion pitting, and seal abrasion.
Forged Steel Body & Baked Enamel
Solid forged alloy steel cylinder barrel is CNC precision-bored and finished with a durable baked enamel coating, delivering superior corrosion protection across outdoor, bridge, and industrial job sites.
Composite Bearing & High-Flow Couplers
High-strength composite bearing bands absorb severe side loads without damaging internal cylinder walls. Outfitted with heavy-duty high-flow 3/8" NPT quick couplers and protective dust caps.
Dimensional Engineering Blueprint
Dimension designations (A: Collapsed Height, B: Extended Height, C: Collar Thread, D: Outside Diameter, F: Plunger Diameter, U/V/Z: Base Mounting Holes) correspond precisely to the Technical Specifications matrix below.
OEM Cross-Reference & Dimensional Interchangeability
The HDC-Series is a heavy-duty, double-acting general-purpose hydraulic cylinder engineered for high-cycle industrial operations, bridge lifting, hydraulic presses, and structural construction maintenance. Powered by 700 Bar (10,000 PSI) working pressure across 10 to 300 Metric Ton capacities, double-acting hydraulic return delivers rapid, controlled retraction under full tonnage, while an integrated retract-side safety relief valve prevents accidental circuit over-pressurization. 10 - 300 Ton / 57 - 511 mm Stroke.
