Airtac BSE Clamp Standard Cylinder BSE32X250
The AirTAC Airtac BSE Clamp Standard Cylinder BSE32X250 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, 250mm stroke, PT1/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE32X250
The AirTAC BSE32X250 is a double-acting single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. It delivers a 600 N bidirectional fail-safe holding force that keeps the piston rod fixed in both directions if air pressure is lost or an E-stop is tripped.
Operating pressure is capped at 0.7 MPa, and the lock unlocks via a separate G1/8 port. Because it uses the standard SE body, all SE mounting accessories fit this model perfectly except for the FTC variant.
Rod Lock — 600 N Static Holding (Ø32mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE32X250 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 BSE32X250 Is Used
Vertical Lift Hold
Secures a 250mm vertical lifting stage on a packaging machine, holding the load safely with 600 N of force if compressed air is exhausted mid-cycle.
Tool Clamp
Maintains a clamping fixture position on an assembly press, ensuring the tool does not drop or release during an emergency stop or sudden pressure loss.
Pneumatic Gate Stop
Holds a conveyor lane diverter gate firmly in place during an E-stop event, preventing unwanted product flow until the system is safely restarted.
Is the Airtac BSE Clamp Standard Cylinder BSE32X250 the Right Cylinder?
Verify your suspended load requires less than the 600 N static holding force. If you need less drive force, the next bore down does not exist in this series, so this 32mm bore is your starting point. If you need more holding or drive capacity, stepping up to the 40mm bore provides 628 N push at 0.5 MPa and a 900 N holding force.
Always engage the collet lock only after the rod has completely stopped, and release it only when piston pressures are balanced, allowing at least 0.5 seconds before moving. At 250mm stroke, use a guide to prevent side-load wear. This SKU lacks a magnet, so position sensing is not available without changing the option code.
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 BSE32X250 FAQ
The integrated rod lock is spring-applied, meaning a loss of air pressure automatically engages the clamping collet. This provides a 600 N bidirectional static holding force that keeps the rod stopped in whatever position it was in, preventing uncommanded drift.
The drive force at 0.5 MPa is 402 N push and 345 N pull, with a maximum push of 563 N at 0.7 MPa (57 kgf). This drive force is separate from the 600 N static holding force provided by the spring-applied rod lock.
