Airtac BSE Clamp Standard Cylinder BSE32X400
The AirTAC Airtac BSE Clamp Standard Cylinder BSE32X400 is a genuine double-acting ISO 15552 cylinder with an integrated spring-applied, air-released ROD LOCK. If air is cut or an E-stop is hit, the collet clamps the Ø12mm rod and holds up to 600 N in either direction — no drift. Ø32mm bore, 400mm stroke, PT1/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE32X400
The AirTAC BSE32X400 is a double-acting ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. It delivers a 600 N bidirectional static holding force, ensuring the piston rod stays firmly clamped in both directions if air pressure drops or an E-stop is hit.
Operating pressure is capped at 0.7 MPa, and the lock uses a separate G1/8 release port to overcome the internal collet. Because this is a holding lock and not a dynamic brake, you must engage it only after the rod stops and allow at least 0.5 s for full release before moving the load.
Rod Lock — 600 N Static Holding (Ø32mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE32X400 holds its position in both directions when air is lost, exhausted or an E-stop trips. Apply 0.15–0.7 MPa to the G1/8 release port to unlock. Engage the lock only after the rod has stopped (it is not a dynamic brake), and release only when the pressures on both sides of the piston are balanced. Allow at least 0.5 s for full release before moving.

Specifications follow the official AirTAC BSE datasheet. The lock uses the SE standard body; SE mounting accessories fit BSE except FTC. Port options: PT (standard) / G (BSPP); lock-release port is G1/8.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa (max) | 563 N | — |
| Max drive (@0.7 MPa) | 57 kgf | |
Drive force is separate from the 600 N static holding force of the lock. BSE operates up to 0.7 MPa. Size with a safety margin.

Where the Airtac BSE Clamp Standard Cylinder BSE32X400 Is Used
Small Vertical Lifts
Holds a 600 N vertical jig securely in place on air loss, preventing drift during an emergency stop on compact assembly machines.
Tooling Clamp
Keeps a light machining fixture locked at 400 mm extension, ensuring the tool stays put without relying on live air pressure.
Pallet Stop Gate
Acts as a fail-safe stop gate that remains clamped mid-stroke if the main air supply drops, protecting downstream parts.
Is the Airtac BSE Clamp Standard Cylinder BSE32X400 the Right Cylinder?
Verify your suspended load requires less than the 600 N static holding force. If you need less drive, there is no smaller BSE bore. If you need more holding and push force, step up to bore 40, which provides 628 N push at 0.5 MPa and 900 N of holding force.
For this 400 mm stroke, add an external guide to prevent side-load wear on the seals. This SKU has no -S magnet, so CMSE or DMSE position sensors will not function without changing the model. SE mounting accessories fit perfectly, except FTC.
Quick checklist
- ✓ Load to hold ≤ 600 N?
- ✓ Fail-safe hold on air loss / E-stop needed
- ✓ Lock engaged only when stopped
- ✓ G1/8 release-air line available
- ✓ Magnet (-S) for CMSE/DMSE sensors?
Installation & Safety Notes
- check Engage the lock only after the rod has stopped — not as 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 Add safety-rated controls for man-rated / overhead loads.
- check Use SE mounting accessories (FTC excepted).
Airtac BSE Clamp Standard Cylinder BSE32X400 FAQ
On air loss, the spring-applied collet engages to provide a 600 N bidirectional static hold. The drive forces are 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a maximum drive of 57 kgf.
Balance pressure on both sides of the piston first, then supply air to the separate G1/8 release port. Wait at least 0.5 seconds for the collet to fully retract before commanding the cylinder to move.
