Airtac BSE Clamp Standard Cylinder BSE100X25
The AirTAC Airtac BSE Clamp Standard Cylinder BSE100X25 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, 25mm stroke, PT1/2 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE100X25
The AirTAC BSE100X25 is a double-acting single-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A collet clamps the 25 mm rod to provide a bidirectional fail-safe holding force of 5500 N. If air pressure drops or an E-stop trips, the lock engages automatically to hold the load in place without live air.
Operating pressure is capped at 0.7 MPa, and unlocking requires 0.15-0.7 MPa supplied to the separate G1/8 release port. The cylinder itself uses a PT1/2 port, features 36 mm adjustable air cushions at both ends, and runs at speeds of 30-800 mm/s. This specific SKU lacks a magnet, so position sensing is not supported.
Rod Lock — 5500 N Static Holding (Ø100mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE100X25 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 (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 BSE100X25 Is Used
Press Ram Hold
Keeps a 100 mm press ram locked mid-stroke during a pneumatic power loss, utilizing the 5500 N holding force to prevent uncontrolled descent.
Heavy Tool Clamp
Secures a large machining fixture in place when the machine's E-stop is hit, ensuring the clamped part does not shift or drop.
Pallet Stopper
Holds a loaded pallet stationary at an assembly station conveyor during an air pressure drop, maintaining position safely until pressure is restored.
Is the Airtac BSE Clamp Standard Cylinder BSE100X25 the Right Cylinder?
Verify your suspended load stays below the 5500 N static holding limit. If your load is lighter, stepping down to the 80 mm bore offers 2513 N push at 0.5 MPa with a 3600 N hold. If you need more drive power, the 125 mm bore provides 6136 N push at 0.5 MPa and an 8600 N hold.
Engage the lock only after the rod has completely stopped, and release it only when piston pressures are balanced, allowing at least 0.5 seconds before moving. This 25 mm stroke is short, so side-load risks are minimal, but always ensure axial load alignment. SE mounting accessories fit this body exactly, except FTC.
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 BSE100X25 FAQ
The spring-applied collet instantly clamps the rod, providing a 5500 N bidirectional static hold. The lock is fail-safe, meaning it requires air pressure on the G1/8 release port to unlock, ensuring the load stays put during power loss.
The drive force is separate from the holding force. At 0.5 MPa, push is 3927 N and pull is 3681 N. At the 0.7 MPa ceiling, push is 5497 N, yielding a max drive of 561 kgf. The static holding force remains 5500 N.
