Airtac BSED Clamping Double Acting Cylinder BSED32X400
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED32X400 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, 400mm stroke, PT1/8 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED32X400
The AirTAC BSED32X400 is a double-acting double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released collet rod lock. A rod exits both ends, delivering equal drive force in both directions at about 345 N each way at 0.5 MPa. The extruded aluminum barrel provides ISO 15552 dimensional interchangeability without external tie rods.
This fail-safe lock provides a 600 N static holding force with no live air required. The lock engages bidirectionally to hold position if air is lost or an E-stop trips. It uses a dedicated G1/8 release port, distinct from the PT1/8 cylinder ports, and operates at a 0.15-0.7 MPa pressure ceiling.
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 BSED32X400 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 BSED32X400 Is Used
Vertical Lift Jig
Holds a 600 N vertical lift jig securely in place during an air loss, while the 345 N both-way force moves the load up and down.
Symmetric Assembly Press
Uses the equal both-way drive to push and retract a tooling head, locking the 12mm rod via collet when E-stop is activated.
Pallet Stop Gate
Extends a stop flag from either end to halt pallets, engaging the fail-safe lock to prevent movement when the system is idle.
Is the Airtac BSED Clamping Double Acting Cylinder BSED32X400 the Right Cylinder?
Select this 32mm bore, 400mm stroke model when an application demands both symmetric both-way force and a 600 N fail-safe hold. If your load to hold exceeds 600 N or you need more drive force, step up to the 40mm bore (528 N @0.5 MPa, 900 N hold). If you need less force, the 32mm is the smallest available bore. 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 s. This SKU has no magnet (-S), so CMSE/DMSE position sensors cannot be used. For a 400mm stroke, use a guide to prevent side-load damage.
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 BSED32X400 FAQ
The integrated spring-applied collet immediately clamps the rod, providing a 600 N static holding force to maintain position. It is a fail-safe lock, not a dynamic brake, so it must only engage after the rod stops.
The drive force is equal both ways: 345 N at 0.5 MPa and 483 N at 0.7 MPa (max 49 kgf). The separate static holding force of the lock is 600 N. Release the lock via the G1/8 port only when both sides are pressure-balanced.
