Product Introduction for New Original Festo 193991 DSNU‑25‑225‑PPV Piston‑Rod Cylinder
1. Product Overview
DSNU‑25‑225‑PPV, part number 193991, belongs to Festo DSNU standard round‑body cylinder series complying with ISO 6432 international standard. It is a double‑acting pneumatic cylinder with a piston rod. The model definition: 25 mm piston bore, 225 mm working stroke, PPV means adjustable pneumatic cushioning on both ends. Compressed air drives the piston rod to extend and retract from two air ports separately. This original German‑made cylinder is widely used in automated assembly lines, material‑handling equipment, conveyor systems, sorting machines and fixture pushing‑and‑pulling applications. It can install proximity sensors to monitor piston‑position signals for automatic‑control systems and meets CE, RoHS and VDMA‑24364‑LABS industrial standards.
2. Main Functions
- Bidirectional linear motion: Produce pushing and pulling force by compressed‑air input from two ports to realize workpiece transferring, positioning and clamping‑release operations.
- Adjustable end‑of‑stroke cushioning: PPV cushioning structure can adjust air‑discharge speed to buffer piston impact at both extended and retracted ends, lower collision noise and reduce internal wear.
- Position‑detection support: Grooves on the cylinder outer surface allow mounting magnetic switches to feed back piston‑rod position to PLC controllers.
- Stable force output: Consistent thrust and pull‑force under rated working‑pressure for long‑cycle continuous‑operation conditions.
- Flexible installation options: Multiple mounting ways including foot mounting, flange mounting and trunnion mounting adapt different installation‑structure requirements.
