Overview
The Festo DZF-25-80-A-PA (part number 161254) is a flat-design double-acting pneumatic cylinder engineered for space-constrained industrial applications. This cylinder is ideal for assembly, automation, and positioning tasks where a compact footprint and reliable linear motion are essential. The DZF series features an extremely flat profile that fits seamlessly into block assemblies.
Key Features
- Compact Flat Design: Exceptionally thin profile maximizes mounting options in tight spaces.
- Anti-Rotation Piston Shape: Special piston geometry prevents unwanted rotation during operation.
- Dual-Side Cushioning: Elastic cushioning rings on both advance and return ends reduce shock and extend service life.
- Male Thread Rod: M10 × 1.25 piston rod with male thread for flexible attachment solutions.
- Aluminum Housing: Lightweight corrosion-resistant aluminum body paired with high-alloy steel piston rod.
- Wide Operating Range: Functions reliably across industrial temperature variations and pressure conditions.
