Airtac BSE Clamp Standard Cylinder BSE125X175
The AirTAC Airtac BSE Clamp Standard Cylinder BSE125X175 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, 175mm stroke, PT1/2 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE125X175
The AirTAC BSE125X175 is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A collet clamps the Ø32 mm rod automatically, delivering 8600 N of bidirectional static holding force with zero live air. This fail-safe architecture ensures heavy suspended loads remain exactly where they stopped if air pressure drops or an E-stop trips.
The cylinder drive operates at 0.15-0.7 MPa, generating a max push of 8590 N (876 kgf), while a separate G1/8 release port unlocks the collet. Because this is a holding lock rather than a dynamic brake, you must engage it only after the rod fully stops and release it only when piston pressures balance, allowing at least 0.5 s before moving. This SKU has no -S magnet, so it does not support CMSE or DMSE position sensors.
Rod Lock — 8600 N Static Holding (Ø125mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE125X175 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.

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 BSE125X175 Is Used
Heavy Press Tooling Hold
Secures 8600 N of vertical press tooling. The spring collet engages instantly on air loss, preventing the heavy ram from dropping unexpectedly mid-cycle.
Palletizer Arm Safety
Stops a 125 mm bore palletizer arm carrying heavy goods. If the E-stop is hit, the fail-safe lock clamps the rod, holding the 876 kgf drive load firmly in place.
Casting Mold Positioner
Maintains a suspended casting mold position during air exhaustion. The collet lock takes over holding duty, ensuring the mold does not drift downward.
Is the Airtac BSE Clamp Standard Cylinder BSE125X175 the Right Cylinder?
Verify your load requires 8600 N or less of holding force and under 8590 N of push at 0.7 MPa. If you need less drive and hold, the neighboring bore 100 provides 3927 N push at 0.5 MPa and 5500 N holding force. As the largest standard bore, 125 mm is the maximum capacity available. When replacing a unit, match the 125 mm bore, 175 mm stroke, PT1/2 port, and mounting choice (SE accessories fit except FTC). Since the 175 mm stroke is under 300 mm, side-load guide requirements are minimal compared to longer strokes.
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 BSE125X175 FAQ
The lock is spring-applied and air-released, providing 8600 N of static holding force with no live air. The drive forces are 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push at 0.7 MPa, and a max drive of 876 kgf. The holding force and drive force are separate.
The lock is not a dynamic brake. Engage it only after the rod has completely stopped. To release, balance the air pressure on both sides of the piston, supply 0.15-0.7 MPa to the G1/8 release port, and wait at least 0.5 seconds before commanding movement.
