Overview
The Festo DGRF-C-GF-32-127-PA-R-A3 (model 563366) is a double-acting guided pneumatic cylinder engineered for reliable, repeatable motion in industrial automation. The DGRF-C series clean design minimizes particle accumulation and is optimized for applications in food, pharmaceutical, and semiconductor environments where contamination control is critical. This 32mm bore cylinder delivers precise linear actuation with integral guide rods that eliminate the need for external rails in many applications.
Key Features
- Clean Design (C) — Reduces contamination and particle build-up for hygienic applications
- Plain-Bearing Guide (GF) — Maintains straight-line motion and reduces deflection under side loads
- Adjustable Pneumatic Cushioning (PPV) — Cushioning is externally adjustable at both ends for customizable deceleration
- Proximity Sensor Port (A) — Pre-equipped mounting for external position feedback sensors
- External Mounting Rail (R) — Dedicated rail for secure sensor installation without additional brackets
- Unlubricated-Operation Seal (A3) — Wiper design suitable for oil-free environments; reduces maintenance intervals
