RAS Series 10-100 Ton Lightweight Aluminum Single-Acting Hydraulic Cylinder Jack

Key Features & Advantages
Ultra-Lightweight Aluminum Body — Aircraft-grade aluminum construction provides maximum portability for easy transport and positioning on job sites, reducing operator fatigue while maintaining structural integrity under full load.
Advanced Hard-Coat Protection — Specialized hard-coat finish on all surfaces resists damage, prevents corrosion, and significantly extends cylinder life even in harsh marine and outdoor environments.
Extended Stroke Options — Available in 100mm and 150mm stroke lengths to handle diverse lifting requirements without frequent repositioning, improving operational efficiency on complex projects.
Superior Side-Load Resistance — Composite support ring and floating center tube design improve seal life and provide exceptional side-load resistance up to 10%, preventing metal-to-metal contact and premature wear.
Safety-First Engineering — Integral stop ring prevents plunger over-travel and is capable of withstanding the full cylinder capacity, protecting both equipment and operators during critical lifting operations.
Rapid Retraction System — High-strength return spring ensures quick cylinder retraction, minimizing cycle time and maximizing productivity on demanding job schedules.
Heavy-Duty Base Protection — Steel base plate and saddle construction prevent load-induced damage, ensuring stable support and even weight distribution across all capacity ranges.
Quick-Connect Convenience — Standardized ZG 3/8 or NPT 3/8 male coupler with dust cap included on all models for fast, secure hydraulic connections and contamination prevention.
