Festo ADVU-16-20-P-A Compact Pneumatic Cylinder

Technical Overview

The Festo ADVU-16-20-P-A (Part No. 156510) is a high-performance, double-acting compact pneumatic cylinder engineered for space-constrained industrial environments. Featuring a 16 mm piston bore and a 20 mm stroke length, this actuator delivers a robust theoretical advance force of 121 N and a return force of 90 N at an operating pressure of 6 bar. Constructed with a wrought aluminum alloy barrel and a high-alloy stainless steel piston rod (with an M4 female thread), it ensures excellent durability and moderate corrosion resistance (CRC 2). The cylinder integrates flexible elastic cushioning rings at both ends to mitigate impact energy (up to 0.1 J) and features an integrated magnetic piston for precise position sensing via proximity sensors. Operating efficiently between 1.2 and 10 bar using M5 pneumatic connections, the ADVU series is optimized to require up to 50% less installation space than standard ISO 15552 cylinders.

Industrial Applications

1. Confined-Space Automated Clamping

Utilizing its ultra-compact footprint—requiring 50% less space than standard ISO cylinders—and a solid 121 N advance force at 6 bar, this cylinder effectively actuates clamps for miniature workpieces in dense automation cells or custom machining fixtures.

Problem Solved

Resolves the engineering challenge of integrating reliable holding force into tightly confined machine cavities where traditional actuators are too bulky.

2. High-Cycle Sorting and Ejection Arrays

In high-speed packaging and quality control lines, the ADVU-16-20-P-A is used to trigger diverter gates or eject rejected items. Its elastic cushioning on both ends successfully absorbs up to 0.1 J of impact energy, preventing mechanical wear.

Problem Solved

Prevents premature failure of lightweight pneumatic components during continuous, high-speed automated sorting operations by utilizing dual-end elastic cushioning to mitigate repeated impact stress.
