HSCA Series Lightweight Aluminum S/A Cylinders
Engineering Overview & Structural Features
The HSCA Series Lightweight Aluminum Single-Acting Hydraulic Cylinders are precision-engineered from ultra-high-yield 7075-T6 aircraft aluminum alloy, delivering up to 60% weight reduction compared to conventional steel cylinders without compromising structural safety. Rated for 700 Bar (10,000 PSI) working pressure across 20 to 150 Metric Ton capacities, every model features deep hard-coat surface finishing, composite non-metallic guide bearings, and heavy-duty steel protection plates at critical wear interfaces for demanding field service.
COMPOSITE BEARINGS & SIDELOAD PROTECTION
High-strength composite bearings eliminate metal-to-metal contact between plunger and barrel, dramatically increasing cylinder service life and providing exceptional resistance against off-center side-loads up to 10% of rated capacity.
HARD-COAT ANODIZING & CORROSION SHIELD
Precision Hard-Coat deep anodized finish on all interior bore and exterior body surfaces resists galling, mechanical surface damage, and severe marine or offshore atmospheric corrosion to extend operating life.
STEEL BASE PLATE & SADDLE DEFENSE
Factory-fitted with a removable hardened steel base protection plate and bolt-on steel saddle to shield lightweight aluminum alloy components from point-load abrasive indentation and substrate deformation.
INTEGRAL STOP RING & FAST RETRACTION
Robust integral stop ring prevents plunger over-travel and withstands 100% rated cylinder tonnage, paired with heavy-duty pretensioned springs for rapid piston retraction, ergonomic carry handles, and ASME B30.1 compliance.
Optional Tilting Saddle Matrix (STG Series, 0° - 5°)
