About the Airtac BSED Clamping Double Acting Cylinder BSED32X25
The AirTAC BSED32X25 is a double-acting, double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A rod exits both ends, delivering equal drive force of 345 N each way at 0.5 MPa, making it ideal for symmetrical pushing and pulling. The rear rod can mount a flag or cam while resisting rotation.
This unit provides a bidirectional fail-safe static holding force of 600 N with no live air required. If pressure drops or an E-stop trips, the collet clamps the 12 mm rod to hold position. It features a 27 mm adjustable air cushion at both ends and a dedicated G1/8 release port. Note: this specific SKU lacks a magnet, so it does not support CMSE or DMSE position sensors.
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 BSED32X25 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 BSED32X25 Is Used
Short-Stroke Diverter
Uses the equal 345 N both-way force to divert light packages on a belt, while the 600 N rod lock holds the gate rigidly in place during air loss to prevent jams.
Pick-and-Place Clamp
Leverages the anti-rotation double-rod design for a stable 25 mm grip, engaging the fail-safe collet to secure the workpiece if shop air pressure suddenly drops.
Symmetric Stopper Gate
Employs the twin rods to push and pull a stopper blade with identical 483 N peak force, locking the 12 mm rod via the G1/8 release port to freeze the gate during E-stops.
Is the Airtac BSED Clamping Double Acting Cylinder BSED32X25 the Right Cylinder?
Select this 32 mm bore when an application requires both symmetrical motion and fail-safe holding up to 600 N. Verify your load does not exceed the 600 N static holding capacity. If you need less drive force, no smaller BSED bore exists; if you need more, step up to the 40 mm bore, which provides 528 N at 0.5 MPa and a 900 N hold.
Engage the lock only after the 25 mm stroke completes, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds. For replacements, match the 32 mm bore, 25 mm stroke, PT1/8 cylinder port, and basic mounting style. Since the stroke is under 300 mm, side-load stress is minimal, but standard guide rules still apply.
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 BSED32X25 FAQ
The double-rod design provides equal drive force in both directions: 345 N at 0.5 MPa and 483 N at 0.7 MPa, with a maximum drive force of 49 kgf. Separately, the spring-applied rod lock provides a static holding force of 600 N with no live air.
The lock is a spring-applied, air-released collet, not a dynamic brake. You must engage it only after the rod stops moving. To release safely, ensure both piston sides are pressure-balanced, apply air to the G1/8 release port, and wait at least 0.5 seconds before commanding motion.
