About the Airtac BSED Clamping Double Acting Cylinder BSED32X400S
The AirTAC BSED32X400S 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 in both directions at about 345 N each way at 0.5 MPa. The collet lock delivers a 600 N static holding force to secure the load safely.
This 32 mm bore unit includes a magnetic piston for CMSE or DMSE sensors. It features a 27 mm adjustable air cushion at both ends and a separate G1/8 lock-release port. The lock engages only after the rod stops and requires both piston sides to be pressure-balanced for release, needing at least 0.5 s.
With a 400 mm stroke, this model is highly susceptible to side loads. You must guide the external mechanism to prevent rod binding and premature seal wear. The extruded aluminum barrel provides a clean ISO 15552 mounting interface without external tie rods.
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 BSED32X400S 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.

|---|---|
| 0.5 MPa | 346 N |
| 0.7 MPa (max) | 484 N |

Where the Airtac BSED Clamping Double Acting Cylinder BSED32X400S Is Used
Vertical Lift Gates
Holds an overhead 400 mm stroke gate securely in place with 600 N of fail-safe clamping force during an air loss event, while the double rod provides equal 345 N lifting and lowering force at 0.5 MPa.
Pick-and-Place Z-Axis
Prevents a vertical pick-and-place Z-axis from crashing down when air is dropped, utilizing the bidirectional collet lock. The rear rod supports a flag for position sensing.
Pallet Stopper Arm
Actuates a 400 mm stroke stopper arm on a conveyor line with equal push and pull force, locking rigidly at 600 N to withstand pallet impacts without relying on live air pressure.
Is the Airtac BSED Clamping Double Acting Cylinder BSED32X400S the Right Cylinder?
Select this 32 mm bore model when an application demands both symmetric force and fail-safe holding. Verify your static load does not exceed the 600 N holding capacity. If you need less holding force, no smaller bore exists in this series. If you need to step up, the 40 mm bore provides 528 N of both-way drive force at 0.5 MPa and a 900 N holding force.
The 400 mm stroke requires a guided external carriage to manage side-loading and prevent cylinder damage. Operating pressure is capped at 0.7 MPa. To replace this unit, match the 32 mm bore, 400 mm stroke, PT1/8 cylinder port, and the -S magnet option. Mounting options include Basic, LB, FA, and TC.
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 BSED32X400S FAQ
The integrated spring-applied collet immediately clamps the rod, providing a 600 N static holding force to prevent movement. It is a fail-safe lock, not a dynamic brake, so it must engage only after the rod stops. To release it, both piston sides must be pressure-balanced, allowing at least 0.5 seconds for the lock to release.
The BSED32X400S provides equal both-way drive force of 345 N at 0.5 MPa and 483 N at 0.7 MPa (a maximum of 49 kgf). The separate static holding force of the spring-applied rod lock is 600 N. The cylinder port is PT1/8, and the lock-release port is G1/8.
