RACL Series Single Acting Aluminum Lock Nut Hydraulic Cylinders

El LONGLOOD RACL Series Single Acting Aluminum Lock Nut Hydraulic Cylinders combine the lightweight advantages of aluminum construction with the safety of a mechanical lock nut for secure, long-term load holding. Designed for demanding lifting applications, these cylinders provide outstanding portability, high lifting capacity, and enhanced operator safety.

With lifting capacities from 20 a 150 montones, strokes from 50 a 250 milímetros, y un maximum operating pressure of 700 bar (10,000 PSI), the RACL Series is ideal for bridge construction, heavy equipment maintenance, structural lifting, synchronized lifting systems, offshore engineering, minería, and industrial plant maintenance.

The integrated lock nut mechanically supports the load after lifting, eliminating reliance on hydraulic pressure alone and providing a safer solution for applications requiring extended load holding.

RACL Series Features

Lightweight Aluminum Alloy Construction

Manufactured from high-strength aerospace-grade aluminum alloy, the RACL Series is significantly lighter than comparable steel cylinders, making transportation, instalación, and positioning easier.

Mechanical Lock Nut for Safe Load Holding

Each cylinder features a precision-machined lock nut that provides positive mechanical load support after lifting. This ensures safe long-term load holding without depending solely on hydraulic pressure.

Single-Acting Spring Return

Hydraulic pressure extends the piston, while a heavy-duty internal spring automatically retracts the piston when pressure is released, improving operating efficiency.

High Strength-to-Weight Ratio

The aluminum cylinder body provides exceptional strength while reducing overall equipment weight, making it ideal for mobile lifting applications.

Hard Chrome-Plated Steel Plunger

The piston rod is manufactured from high-strength steel with a hard chrome-plated finish for superior wear resistance, corrosion protection, and long service life.

Composite Bearing System

Heavy-duty composite bearings reduce friction, improve load stability, and extend cylinder service life under demanding operating conditions.

Corrosion-Resistant Surface

The hard-coated aluminum body provides excellent protection against corrosion, making the cylinder suitable for outdoor, marina, and humid environments.

Anillo de tope integral

An internal stop ring prevents piston over-extension and enhances operational safety.

Easy Handling

The lightweight aluminum design allows operators to transport and position the cylinder quickly, reducing labor requirements and improving productivity.

700 Bar Maximum Operating Pressure

Designed for continuous operation at 700 bar (10,000 PSI), ensuring reliable performance for heavy-duty lifting applications.
