Airtac BSE Clamp Standard Cylinder BSE32X125
The AirTAC Airtac BSE Clamp Standard Cylinder BSE32X125 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, 125mm stroke, PT1/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE32X125
The AirTAC BSE32X125 is a double-acting ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. It delivers a bidirectional fail-safe holding force of 600 N, ensuring suspended loads remain fixed in place if air pressure is exhausted or an E-stop is triggered. The cylinder operates at 0.15-0.7 MPa and uses a separate G1/8 release port to unlock the collet.
This unit has a 32 mm bore and 125 mm stroke, providing a drive force of 402 N push and 345 N pull at 0.5 MPa. The lock is a static holding device, not a dynamic brake. You must engage the lock only after the rod fully stops, and release it only when piston pressures are balanced, allowing at least 0.5 seconds for full release before motion. This SKU has no magnet and supports no position sensors.
Rod Lock — 600 N Static Holding (Ø32mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE32X125 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 BSE32X125 Is Used
Pneumatic Vertical Lift
Holds a 60 kg vertical lift gate firmly in place with 600 N of holding force during a power loss, preventing gravity-driven descent.
Tooling Clamp Hold
Secures a light machining fixture clamp with 600 N of static force, ensuring the collet lock prevents drift if shop air is suddenly exhausted.
Package Diverter Stop
Maintains a conveyor sorting diverter arm exactly in position during an E-stop, relying on the spring-applied collet rather than live air.
Is the Airtac BSE Clamp Standard Cylinder BSE32X125 the Right Cylinder?
Verify your load requires a holding force of 600 N or less, distinct from the 402 N push drive force. If you need less holding power, the BSE series does not offer a smaller standard bore. If your load exceeds 600 N, step up to the 40 mm bore, which provides 628 N push at 0.5 MPa and 900 N of holding force. When replacing a unit, match the 32 mm bore, 125 mm stroke, PT1/8 cylinder port, and mounting style. SE mounting accessories fit this cylinder except for FTC. Since the 125 mm stroke is under 300 mm, side-load guide concerns are minimal, but always ensure linear motion.
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 BSE32X125 FAQ
The drive force is 402 N push and 345 N pull at 0.5 MPa, and 563 N push at 0.7 MPa (max 57 kgf drive). The static holding force of the integrated rod lock is 600 N. The lock holds the load with no live air, while the drive force moves it.
The lock is spring-applied and air-released via a separate G1/8 port. You must engage the lock only after the rod stops moving. To release it, balance pressures on both sides of the piston and supply 0.15-0.7 MPa to the release port, waiting at least 0.5 seconds before commanding motion.
