Festo ADVU-32-50-A-P-A Compact Pneumatic Cylinder

Technical Overview

The Festo ADVU-32-50-A-P-A (part number 156623) is a double-acting compact pneumatic cylinder with a 32 mm bore and 50 mm stroke. Designed for space-efficient industrial applications, it requires 50% less installation space compared to standard ISO 15552 cylinders. The cylinder features an M10x1.25 male threaded piston rod, flexible elastic cushioning rings at both ends, and a magnetic piston that enables accurate proximity sensing. Constructed with a wrought aluminum alloy barrel and a high-alloy steel piston rod, it operates safely between 0.8 to 10 bar pressure. It connects via standard G1/8 pneumatic ports and is rated for ambient environments ranging from -20°C to 80°C.

2. Material Handling and Sorting Gates

In pneumatic sorting and packaging systems, the ADVU cylinder actuates diverter gates at high speeds. The flexible cushioning plates absorb the kinetic energy (0.4 J) of fast-moving strokes, minimizing mechanical wear.

Problem Solved

Prevents mechanical fatigue and damage in high-speed repetitive diverter operations by utilizing built-in flexible cushioning to absorb end-position impacts.

3. Workpiece Clamping Fixtures

This compact cylinder effectively holds workpieces in place during CNC machining or welding operations. Operating reliably up to 10 bar pressure, it exerts strong clamping force, while its CRC 2 rating ensures resistance to moderate factory coolants and ambient moisture.

Problem Solved

Addresses the need for reliable, high-pressure clamping in moisture-exposed machine tool environments where the physical space surrounding the tooling area is severely restricted.
