Festo ADVU-100-20-P-A Compact Pneumatic Cylinder

Technical Overview

The Festo ADVU-100-20-P-A (Part No. 156579) is a high-performance, double-acting compact pneumatic cylinder engineered for heavy-duty linear actuation in space-constrained environments. Featuring a substantial 100 mm piston diameter and a precise 20 mm stroke, it delivers exceptional mechanical force—up to 4712 N on advance at 6 bar. Constructed with a robust wrought aluminum alloy barrel and a high-alloy steel piston rod, it ensures long-term industrial reliability. The unit integrates elastic cushioning pads at both ends to absorb impact shock and operates efficiently across a pressure range of 0.6 to 10 bar, making it the premier choice for tight-footprint machinery requiring substantial clamping, pressing, or lifting power.

Key Features

Ultra-compact footprint optimized for linear motion in strictly limited installation spaces [1.1].
Double-acting pneumatic operation generating a massive 4712 N theoretical advancing force at 6 bar.
Integrated elastic cushioning rings/pads at both stroke ends to minimize impact shock and extend machine lifespan.
Durable wrought aluminum alloy housing paired with a high-alloy steel piston rod and NBR/TPE-U(PU) dynamic seals.
Internal M12 piston rod thread and G1/4 pneumatic connections for versatile integration.

Industrial Applications

1. Automated Bearing Press-Fitting

In automated powertrain assembly lines, bearings, bushings, and pins must be pressed into precision housings requiring intense local force. The cylinder's short 20 mm stroke paired with a massive 4712 N advancing capability enables rigid, high-tonnage pressing within a highly restricted tooling envelope.

Problem Solved

Provides extreme linear pressing force in confined machine spaces where traditional tie-rod or profile cylinders are simply too long to fit.

2. Heavy-Duty CNC Fixture Clamping

Integrated into CNC machining centers and robotic welding cells to securely immobilize large, heavy metallic workpieces. The 100 mm bore easily delivers over 4400 N of holding/retracting force, ensuring strict component immobility during high-torque multi-axis milling operations.

Problem Solved

Eliminates part slippage and chatter during aggressive machining operations by applying immense holding force with minimal interference to the cutting tool path.

3. Sheet Metal Punching & Staking

Utilized in localized sheet metal fabrication machinery where localized deformations, embossing, or shallow punching is required. The rapid double-acting pneumatic acceleration combined with elastic end cushioning facilitates high-cycle, high-impact force over short 20 mm distances.

Problem Solved

Delivers rapid, repetitive high-impact force for mechanical deformation while actively mitigating destructive mechanical shock via built-in elastic end-position cushioning.
