Airtac BSE Clamp Standard Cylinder BSE125X160
The AirTAC Airtac BSE Clamp Standard Cylinder BSE125X160 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 Ø32mm rod and holds up to 8600 N in either direction — no drift. Ø125mm bore, 160mm stroke, PT1/2 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE125X160
The AirTAC BSE125X160 is a double-acting ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A collet clamps the Ø32 mm piston rod instantly if air is exhausted or an E-stop trips, delivering a bidirectional static holding force of 8600 N with zero live air. The operating pressure ceiling is capped at 0.15-0.7 MPa.
This fail-safe mechanism is a holding lock, not a dynamic brake. You must engage the lock only after the rod stops, and release it only when pressures on both sides of the piston are balanced, allowing at least 0.5 s for full release before moving. The lock unlocks via a separate G1/8 port, while the main cylinder uses a PT1/2 port. This SKU has no -S magnet, so position sensing is not available.
Rod Lock — 8600 N Static Holding (Ø125mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE125X160 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 (Ø125mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 6136 N | 5734 N |
| 0.7 MPa (max) | 8590 N | — |
| Max drive (@0.7 MPa) | 876 kgf | |
Drive force is separate from the 8600 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 BSE125X160 Is Used
Heavy Vertical Press
Secures an 880 kg vertical press slide mid-stroke, providing 8600 N of fail-safe holding force the instant shop air drops.
Large Injection Mold Clamp
Locks a heavy mold halting jig securely in place during an emergency stop, preventing uncontrolled drops with its 8600 N collet grip.
Pallet Stopper Gate
Holds a loaded pallet conveyor gate rigid in both directions during an E-stop, relying on the spring-applied lock rather than live air pressure.
Is the Airtac BSE Clamp Standard Cylinder BSE125X160 the Right Cylinder?
Verify your suspended load does not exceed the 8600 N holding force. If stepping down, the bore 100 provides 3927 N push at 0.5 MPa and a 5500 N hold. If stepping up, 125 mm is the largest standard bore offering 6136 N push at 0.5 MPa and 876 kgf max drive at 0.7 MPa. SE mounting accessories fit this body except FTC. For exact replacement, match the 160 mm stroke, PT thread, and basic mounting.
Quick checklist
- ✓ Load to hold ≤ 8600 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 BSE125X160 FAQ
The spring-applied collet instantly clamps the rod, providing a bidirectional static holding force of 8600 N with no live air. It is a fail-safe hold, not a dynamic brake, so it must only be engaged after the rod has completely stopped.
The drive force is separate from the holding force. At 0.5 MPa, push is 6136 N and pull is 5734 N. At the 0.7 MPa ceiling, push is 8590 N (max 876 kgf drive). The static lock holding force is 8600 N.
