Airtac BSE Clamp Standard Cylinder BSE100X125S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE100X125S 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 Ø25mm rod and holds up to 5500 N in either direction — no drift. Ø100mm bore, 125mm stroke, PT1/2 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE100X125S
The AirTAC BSE100X125S is a double-acting, single-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A collet clamps the Ø25 mm rod to deliver a 5500 N bidirectional static holding force. The fail-safe design holds the load in both directions with no live air if pressure drops or an E-stop trips. Operating pressure is capped at 0.7 MPa.
The lock uses a separate G1/8 release port, meaning the standard air cushions are not the holding device. Because the body uses the SE ISO 15552 mounting interface, SE accessories fit this model except for FTC. The -S magnet option enables position sensing with CMSE reed or DMSE electronic sensors. The lock is a holding device, not a dynamic brake; engage it only after the rod stops and release it only when pressures are balanced.
Rod Lock — 5500 N Static Holding (Ø100mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE100X125S 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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa (max) | 5498 N | — |
| Max drive (@0.7 MPa) | 561 kgf | |
Drive force is separate from the 5500 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 BSE100X125S Is Used
Vertical Press Hold
Maintains 5500 N of fail-safe holding force on a vertical press ram during air loss or E-stop, preventing uncommanded descent.
Heavy Tool Clamp
Secures a machining fixture with 5497 N of drive force at 0.7 MPa, then locks the Ø25 mm rod to keep the clamp engaged if air exhausts.
Pallet Stop Gate
Acts as a heavy pallet stop gate that stays rigidly put via the collet lock when the line halts, surviving pressure drops without drifting.
Is the Airtac BSE Clamp Standard Cylinder BSE100X125S the Right Cylinder?
Verify your load does not exceed the 5500 N static holding force. If your load is lighter, the BSE80 steps down with a 2513 N push at 0.5 MPa and a 3600 N hold. If you need more drive force, the BSE125 steps up with a 6136 N push at 0.5 MPa and an 8600 N hold.
Follow the safety operating rule: engage the lock only after the rod stops, and release it only when both sides are pressure-balanced, allowing at least 0.5 s before moving. For a drop-in replacement, match the 100 mm bore, 125 mm stroke, PT1/2 port, and your specific mounting and magnet options. The 125 mm stroke is short enough to minimize typical side-load deflection, but always guide the load to prevent rod bending.
Quick checklist
- ✓ Load to hold ≤ 5500 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 BSE100X125S FAQ
The drive force is 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, with a max drive of 561 kgf. The separate static holding force of the spring-applied lock is 5500 N.
The lock is spring-applied and fail-safe, so if air is lost or exhausted, the collet immediately clamps the rod to hold the load in both directions up to 5500 N. You must supply 0.15-0.7 MPa to the G1/8 release port to free it.
