Airtac BSED Clamping Double Acting Cylinder BSED32X250
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED32X250 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, 250mm stroke, PT1/8 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED32X250
The AirTAC BSED32X250 is a double-acting, double-rod ISO 15552 profile cylinder featuring a spring-applied, air-released rod lock. A rod exits both ends, delivering equal force and speed in both directions—about 345 N each way at 0.5 MPa. The integrated collet mechanism provides a bidirectional 600 N static holding force to secure the load safely.
Because it uses an extruded aluminum barrel, this cylinder offers a clean ISO 15552 mounting interface without external tie rods. The lock engages automatically if air pressure drops, requiring a separate G1/8 release port to pressure-balance and free the rod. 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 BSED32X250 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 BSED32X250 Is Used
Vertical Lift Jigs
Holds a 600N vertical jig in place instantly upon air loss, while the double-rod provides equal 345N lifting and lowering force at 0.5 MPa.
Mid-Stop Machining
Stops a tooling carriage securely mid-stroke for a machining op, using the rear rod for an external flag while the collet locks statically.
Transfer Diverter
Indexes a conveyor diverter arm with symmetric both-way speed, engaging the fail-safe lock to prevent drift during the product transfer cycle.
Is the Airtac BSED Clamping Double Acting Cylinder BSED32X250 the Right Cylinder?
Select this 32mm bore model when your application requires both symmetric drive force and fail-safe holding up to 600 N. If your load requires less holding or drive force, the next size down is unavailable, making 32mm the entry point. If you need more force, step up to the 40mm bore, which provides 528 N at 0.5 MPa drive force and 900 N of holding force. Always engage the lock only after the rod stops, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds for the transition. At 250mm stroke, ensure your mounting resists side-loads by using external guides. When replacing, match the 32mm bore, 250mm stroke, PT1/8 cylinder port, and basic mounting.
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 BSED32X250 FAQ
The spring-applied collet engages automatically, providing a 600N static holding force to keep the rod fixed in place. It is a fail-safe lock, not a dynamic brake, so it only engages after the rod stops moving. To release it, you must apply pressure to the G1/8 release port after balancing both piston sides.
The BSED32X250 delivers equal drive force in both directions: 345N at 0.5 MPa and 483N at 0.7 MPa, with a maximum drive of 49kgf. The static holding force of the integrated rod lock is 600N.
