Airtac BSE Clamp Standard Cylinder BSE125X1000S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE125X1000S 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, 1000mm stroke, PT1/2 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE125X1000S
The AirTAC BSE125X1000S is a double-acting, single-rod ISO 15552 profile cylinder equipped with an integrated spring-applied, air-released rod lock. It delivers a massive 8600 N bidirectional static holding force with zero live air, ensuring suspended loads remain exactly where they stopped during an E-stop or pressure loss. Operating pressure is capped at 0.7 MPa, and the cylinder port is PT1/2.
This 125 mm bore, 1000 mm stroke unit features a Ø32 mm rod and adjustable air cushions at both ends. The fail-safe collet mechanism engages only after the piston stops, while a separate G1/8 release port unlocks the rod when piston pressures are balanced. The integrated -S magnet supports CMSE reed and DMSE electronic sensors for precise position feedback.
Rod Lock — 8600 N Static Holding (Ø125mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE125X1000S 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 BSE125X1000S Is Used
Heavy Vertical Lifts
Secures 8600 N vertical press platens and heavy lifting stages, preventing catastrophic drops if the main air supply fails.
Overhead Tooling Clamp
Holds large machining heads firmly in place during an emergency stop, ensuring heavy spindles do not drift down onto the workpiece.
Pallet Stop Gate
Maintains a rigid 1000 mm stroke barrier for heavy pallet flows, locking solid instantly when the pneumatic system exhausts.
Is the Airtac BSE Clamp Standard Cylinder BSE125X1000S the Right Cylinder?
Verify your load requires a holding force under the 8600 N limit and a drive force below the 876 kgf maximum at 0.7 MPa. If you need less force, stepping down to the 100 mm bore yields a 3927 N push at 0.5 MPa and a 5500 N hold. As the largest standard bore, there is no larger option available. Always engage the lock only after the rod stops, and allow at least 0.5 s for full release before resuming motion. At 1000 mm stroke, use external guide rails to prevent excessive side-loading on the piston rod. This unit replaces any BSE125X1000S matching the PT thread, basic mounting, and magnet options; SE mounting accessories fit except FTC.
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 BSE125X1000S FAQ
The spring-applied collet clamp engages automatically, delivering an 8600 N bidirectional static holding force to freeze the rod in place without any live air. It is a fail-safe lock, not a dynamic brake, so it must only engage after the rod has stopped moving.
The drive force at 0.5 MPa is 6136 N push and 5734 N pull, while at 0.7 MPa the push is 8590 N (max 876 kgf). The separate static holding force of the rod lock is 8600 N. Release the lock via the G1/8 port only after balancing piston pressures.
