Airtac BSED Clamping Double Acting Cylinder BSED32X25S
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED32X25S combines a double-rod ISO 15552 cylinder — a Ø12mm rod out BOTH ends for equal force both directions — with an integrated spring-applied, air-released ROD LOCK that holds up to 600 N in either direction if air is lost. Ø32mm bore, 25mm stroke, PT1/8 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED32X25S
The AirTAC BSED32X25S is a double-acting, double-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A rod exits both ends, yielding equal drive force of 345 N each way at 0.5 MPa. The rear rod is ideal for mounting flags or anti-rotation tooling.
This compact 32 mm bore unit features a bidirectional collet that clamps the rod to provide a 600 N static holding force with no live air. It includes a separate G1/8 release port, adjustable air cushions at both ends, and a magnetic piston for position sensing.
Double Rod + 600 N Rod Lock (Ø32mm)
A rod exits both ends for symmetric force and back-rod tooling, and a spring clamps the collet so the Airtac BSED Clamping Double Acting Cylinder BSED32X25S holds its position in both directions on air loss or E-stop. Apply 0.15–0.7 MPa to the G1/8 release port to unlock. Engage only after the rod has stopped (not a dynamic brake), and release only when both piston sides are pressure-balanced; allow ≥0.5 s for full release.

Specifications follow the official AirTAC BSED datasheet. Rod thread M10×1.25 both ends. Mounting (BSED): Basic, LB, FA, TC. Port options: PT (standard) / G (BSPP); lock-release port is G1/8.
Theoretical Output Force (Ø32mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 346 N |
| 0.7 MPa (max) | 484 N |
| Max drive (@0.7 MPa) | 49 kgf |
A rod exits both ends, so force is equal on extend and retract. Drive force is separate from the 600 N static lock holding force. Size with a safety margin.

Where the Airtac BSED Clamping Double Acting Cylinder BSED32X25S Is Used
Gripper Fixture Hold
Secures a pick-and-place gripper mid-cycle with 600 N of fail-safe holding force while delivering 345 N of equal both-way drive for stable part transfer.
Symmetric Stopper Gate
Uses the double-rod anti-rotation特性 to push and pull a conveyor diverter gate with identical 483 N force, locking securely during air loss.
E-Stop Position Retention
Maintains a light pneumatic actuator position safely during an E-stop event via the spring-applied collet, preventing drift without live air.
Is the Airtac BSED Clamping Double Acting Cylinder BSED32X25S the Right Cylinder?
Select this model when your application demands both symmetric thrust and fail-safe holding. Verify your load requires 600 N or less of static hold. If you need less force, a smaller bore is unavailable, but stepping up to bore 40 provides 528 N at 0.5 MPa and a 900 N holding force. Operating pressure is capped at 0.7 MPa.
Engage the lock only after the rod completely stops, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 s. For replacements, match the 25 mm stroke, PT1/8 port, M10x1.25 rod thread, and the -S magnet option for CMSE or DMSE sensors.
Quick checklist
- ✓ Need both symmetric force AND fail-safe hold?
- ✓ Load to hold ≤ 600 N?
- ✓ Back-rod space for tooling/flag
- ✓ Lock engaged only when stopped
- ✓ G1/8 release-air line available
Installation & Safety Notes
- check Engage the lock only after the rod has stopped — not a dynamic brake.
- check Release only when both piston sides are pressure-balanced.
- check Allow ≥0.5 s for full release before commanding motion.
- check Feed the G1/8 release port with 0.15–0.7 MPa clean air.
- check Support both rod ends; avoid side load.
- check Use BSED mounting (Basic/LB/FA/TC).
Airtac BSED Clamping Double Acting Cylinder BSED32X25S FAQ
The drive force is equal in both directions, providing 345 N at 0.5 MPa and 483 N at 0.7 MPa, with a maximum drive of 49 kgf. The fail-safe rod lock provides a separate 600 N static holding force.
The spring-applied collet automatically clamps the rod, delivering up to 600 N of static holding force without live air. To release it safely, pressure must be balanced on both piston sides for at least 0.5 s.
