READ MOREThe RAS Series is a premium lightweight hydraulic cylinder jack engineered for professionals who demand maximum portability without compromising power. Featuring high-strength aluminum construction and advanced hard-coat surface technology, this single-acting cylinder delivers exceptional performance across 10 to 100 ton capacities. Designed for shipbuilding, construction, bridge engineering, and industrial maintenance where weight matters and reliability is critical.
Product Details
Every RAS Series cylinder includes an integrated dust ring for seal protection, a quick connector with a protective dust cap, a smooth surface finish for jam-free operation, a high-strength return spring for rapid retraction, and ergonomic design elements for easy handling. The composite bearing system prevents metal contact while improving side-load capacity, ensuring reliable performance throughout the cylinder's extended service life.

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.
