About the Airtac BSED Clamping Double Acting Cylinder BSED32X450
The AirTAC BSED32X450 is a double-acting, double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A rod exits both ends, providing equal drive force of 345 N each way at 0.5 MPa, while the rear rod resists rotation and can carry a flag or cam. The collet lock delivers a bidirectional static holding force of 600 N with no live air required.
This unit features a 32 mm bore, 450 mm stroke, and a PT1/8 cylinder port, with a separate G1/8 release port. The lock engages only after the rod stops and releases when piston sides are pressure-balanced (allow at least 0.5 s). This SKU is supplied without 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 BSED32X450 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 BSED32X450 Is Used
Mid-Stroke Z-Axis Hold
Holds a 450 mm vertical lift stage firmly in place with 600 N of fail-safe force during air loss, while the double-rod design ensures equal 345 N lifting and lowering drive at 0.5 MPa.
Symmetric Transfer Gate
Operates a horizontal gating mechanism where the double rod provides identical 345 N force in both directions, and the collet lock prevents drift when the 0.15-0.7 MPa air supply is removed.
Anti-Rotation Tooling Slide
Uses the rear rod to mount a secondary cam and resist rotation on a 450 mm stroke, clamping securely with 600 N of static hold when E-stop is activated.
Is the Airtac BSED Clamping Double Acting Cylinder BSED32X450 the Right Cylinder?
Select this 32 mm bore model when your application demands both symmetric force and fail-safe hold; verify your load does not exceed the 600 N static holding force. If you need less drive force, there is no smaller BSED bore. If you need more, step up to the 40 mm bore, which provides 528 N at 0.5 MPa and a 900 N holding force. Operating pressure is capped at 0.7 MPa.
Because the 450 mm stroke is relatively long, use a guide to prevent side-load damage to the seals. To match this cylinder for a replacement, confirm the 32 mm bore, 450 mm stroke, PT thread, and Basic/LB/FA/TC mounting choice. Remember to engage the lock only when the rod is stationary and release it only when both sides are pressure-balanced.
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 BSED32X450 FAQ
The drive force is equal in both directions: 345 N at 0.5 MPa and 483 N at 0.7 MPa, with a maximum drive of 49 kgf at 0.7 MPa. The separate spring-applied rod lock provides a static holding force of 600 N.
The spring-applied collet clamps the rod automatically if air is lost, holding the load up to 600 N. It is not a dynamic brake. To release, apply air to the G1/8 port only after both piston sides are pressure-balanced, allowing at least 0.5 seconds for the collet to disengage.
