Airtac BSE Clamp Standard Cylinder BSE32X450S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE32X450S 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, 450mm stroke, PT1/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE32X450S
The AirTAC BSE32X450S is a double-acting ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A collet clamps the 12mm rod to deliver a 600N bidirectional fail-safe hold, securing your load instantly if air pressure drops. Operating pressure is capped at 0.7 MPa, and the lock is released via a dedicated G1/8 port.
This 32mm bore, 450mm stroke model includes a magnet for position sensing. The lock is a static holding device, not a dynamic brake; it must be engaged only after the piston stops, with a minimum 0.5s release delay. The extruded aluminum barrel provides a clean ISO 15552 mounting interface without external tie rods.
Rod Lock — 600 N Static Holding (Ø32mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE32X450S 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 BSE32X450S Is Used
Vertical Pneumatic Lifts
Holds suspended jigs weighing up to 600N securely in place during air loss, preventing sudden drops on vertical lifting stations.
Pallet Stops
Maintains a rigid stop position for pallets on a 32mm conveyor line, keeping the rod locked firmly even during an E-stop event.
Tool Clamping
Keeps machining tooling locked at the 450mm extended position, ensuring the collet holds the load with zero live air.
Is the Airtac BSE Clamp Standard Cylinder BSE32X450S the Right Cylinder?
Verify your load requires a holding force of 600N or less. If you need less drive, a smaller bore is unavailable, but if you need more, step up to the 40mm bore, which provides 628N push at 0.5MPa and 900N holding force. Always engage the lock only after the rod fully stops, and release it only when piston pressures are balanced.
At 450mm stroke, prevent side-loading by guiding the load externally to avoid binding. For exact replacement, match the 32mm bore, 450mm stroke, PT1/8 cylinder port, and -S magnet option. SE mounting accessories fit this body entirely except for FTC brackets.
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 BSE32X450S FAQ
The spring-applied collet instantly clamps the rod, delivering a 600N bidirectional static hold. The lock engages automatically without live air, securing the load in its stopped position.
Drive forces at 0.5MPa are 402N push and 345N pull, with a 563N push at 0.7MPa (max 57kgf). The separate static holding force of the rod lock is 600N.
