Airtac BSE Clamp Standard Cylinder BSE125X600S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE125X600S 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, 600mm stroke, PT1/2 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE125X600S
The AirTAC BSE125X600S is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It delivers a massive 8600 N bidirectional static holding force with no live air, preventing heavy suspended loads from drifting or dropping if pressure drops. Operating pressure is capped at 0.7 MPa.
This 125 mm bore, 600 mm stroke unit uses a separate G1/8 release port to unlock the collet. The lock is a holding device, not a dynamic brake; it must engage only after the rod stops and release only when pressures balance. The included -S magnet enables position sensing with CMSE reed or DMSE electronic sensors.
Rod Lock — 8600 N Static Holding (Ø125mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE125X600S 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 BSE125X600S Is Used
Heavy Press Tooling Clamp
Secures 8590 N of press drive force and locks the tooling in place with 8600 N of fail-safe holding power, ensuring the clamp does not drop during an E-stop.
Palletizer Vertical Lift
Holds a lifted pallet assembly mid-stroke with 8600 N of static force, preventing sudden falls if the main air supply is exhausted or a hose bursts.
Automated Foundry Gate
Drives a heavy foundry safety gate with 876 kgf max drive force and locks it open against vibration, keeping the path clear during maintenance.
Is the Airtac BSE Clamp Standard Cylinder BSE125X600S the Right Cylinder?
Verify your load requires less than the 8600 N holding force. If you need less holding and drive power, step down to the 100 mm bore, which provides 3927 N push at 0.5 MPa and 5500 N holding force. If you need more drive force, this 125 mm bore is the largest standard size offering 6136 N push at 0.5 MPa. Always engage the lock only after the rod stops, and allow at least 0.5 s for full release before moving.
For a 600 mm stroke, use a guide to prevent side-load damage to the seals. When replacing a unit, match the 125 mm bore, 600 mm stroke, PT1/2 cylinder port, and mounting style. SE mounting accessories fit this cylinder 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 BSE125X600S FAQ
The lock is spring-applied and air-released, meaning a loss of air causes the collet to clamp the rod instantly. It provides a bidirectional fail-safe hold with 8600 N of static holding force, keeping the load exactly where it stopped.
The drive force is 6136 N push and 5734 N pull at 0.5 MPa, and 8590 N push at 0.7 MPa (max 876 kgf drive). The separate static holding force of the rod lock is 8600 N.
