RAC Series Features

Lightweight Aluminum Construction

Manufactured from high-strength aerospace-grade aluminum alloy, the RAC Series offers exceptional strength while significantly reducing weight compared to traditional steel hydraulic cylinders.

High Strength-to-Weight Ratio

The advanced aluminum body provides excellent durability and load-bearing capability while remaining easy to transport and position.

Single-Acting Spring Return

Hydraulic pressure extends the piston, while an internal spring automatically retracts the plunger when pressure is released, enabling faster operation and improved productivity.

Hard-Coated Surface Protection

The cylinder body is treated with a wear-resistant coating that improves corrosion resistance and protects against harsh industrial environments.

Hard Chrome-Plated Steel Plunger

Precision-machined steel plungers with hard chrome plating ensure superior wear resistance, عملية سلسة, and extended service life.

Composite Bearings

High-performance composite bearings reduce friction, minimize wear, and improve cylinder longevity under heavy loads.

High-Strength Return Spring

A heavy-duty spring ensures rapid and reliable piston retraction for efficient operation.

حلقة توقف متكاملة

An internal stop ring prevents over-stroking and provides additional protection against accidental plunger over-extension.

Easy Handling

The lightweight design reduces operator fatigue and improves portability, making the RAC Series ideal for field maintenance and mobile lifting applications.

700 Bar Maximum Working Pressure

Engineered for safe operation at 700 حاجِز (10,000 رطل لكل بوصة مربعة) to deliver maximum lifting performance.
