Overview of RC-Series DUO Single-Acting Cylinders

The RC-Series DUO cylinders are industry-standard, general-purpose hydraulic cylinders designed for lifting and other applications. They range in capacity from 5 to 95 tons with strokes from 16 to 362 mm and operate at a maximum pressure of 700 bar.

Key Features

• Unique GR2 bearing design reduces wear and protects against eccentric loads, abrasion, and plunger damage.
• Collar threads, plunger threads, and base mounting holes facilitate easy fixturing on most models.
• High-strength alloy steel construction ensures durability.
• Redesigned cylinder thread protector enhances usability.
• Heavy-duty, pretensioned spring improves retraction speed.
• Baked enamel finish increases corrosion resistance.
• CR-400 coupler and dust cap included on all models.
• Plunger wiper reduces contamination, extending cylinder life.

Accessories and Attachments

• Saddles: Hardened removable grooved saddles are standard on all models except RC-50 and RC-101. Tilt and flat saddles are available as accessories.
• Base Plates: Available for 10, 25, and 50 ton cylinders to ensure stability during lifting applications.
• Specialty Attachments: Designed to solve various application challenges, available for 5, 10, and 25 ton cylinders.

Applications

• Synchronous lifting setups, such as lifting a 200-ton petrochemical process module using multiple RC-2510 cylinders with base plates for stability.
• Foundation repair, demonstrated by lifting and leveling a 308-ton silo using 25-ton RC-Series hydraulic jacks powered by a Z-Class pump.

Technical Specifications

The document provides detailed technical data including:

• Cylinder effective area, capacity (tons and kN), stroke length, collapsed and extended heights.
• Oil capacity per cylinder model.
• Dimensions such as bore diameter, plunger diameter, saddle diameter, and mounting thread sizes.
• Weight of each cylinder model.
• Thread specifications for collar and plunger threads.

All cylinders include CR-400 couplers compatible with HC-Series hoses. Some models are available as complete cylinder-pump sets for convenience.

Safety and Best Practices

• Manufacturer’s load and stroke ratings represent maximum safe limits; recommended usage is up to 80% of these ratings for safety and longevity.
• Use of gauges is advised to minimize overloading risks and ensure reliable operation.

Additional Product Lines and Components

• Lightweight Aluminium Cylinders (RAC-Series): Offer higher capacity-to-weight ratios for applications requiring portability.
• Multifluid Hand Pumps (MP-Series): Corrosion-resistant pumps suitable for low-pressure filling and high-pressure testing with a wide range of fluids.
• Extreme Environment Products: Cylinders and pumps designed for wet, high-temperature, or chemically aggressive environments, featuring corrosion-resistant materials and Viton® seals.
• Valves: Manual check valves and pressure relief valves with precise pressure control and repeatability.

Selection and Dimension Charts

The document includes comprehensive selection charts listing model numbers, capacities, strokes, dimensions, oil capacities, and weights. Dimension charts provide detailed measurements for saddles, base plates, mounting blocks, and clevis eyes to assist in proper equipment selection and installation.

Summary

The RC-Series DUO cylinders are robust, versatile hydraulic cylinders suitable for a wide range of industrial lifting and pressing applications. Their design emphasizes durability, ease of use, and safety. The availability of various accessories and specialty attachments enhances their adaptability.
