Airtac BSE Clamp Standard Cylinder BSE80X250S
The AirTAC BSE Clamp Standard Cylinder BSE80X250S 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 3600 N in either direction — no drift. Ø80mm bore, 250mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE80X250S
The AirTAC BSE80X250S is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A collet clamps the 25 mm rod to provide a 3600 N bidirectional static holding force. This fail-safe mechanism holds the load securely in both directions with no live air if pressure drops or an E-stop trips. Operating pressure is capped at 0.7 MPa, and a separate G1/8 port supplies 0.15-0.7 MPa to release the lock.
The lock is a holding device, not a dynamic brake. Engage it only after the rod fully stops, and release it only when pressures on both sides of the piston are balanced. Allow at least 0.5 s for full release before commanding motion. This 80 mm bore includes a magnet for CMSE and DMSE sensors, uses PT3/8 cylinder ports, and runs at 30-800 mm/s. SE mounting accessories fit this body, except FTC.
Rod Lock — 3600 N Static Holding (Ø80mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE80X250S 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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa (max) | 3519 N | — |
| Max drive (@0.7 MPa) | 359 kgf | |
Drive force is separate from the 3600 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 BSE80X250S Is Used
Vertical Lift Gates
Holds 3600 N vertical lift gates instantly in place during air loss, preventing gravity drops while the 2513 N push force drives the lift cycle.
Machine Tool Clamp
Keeps a heavy machining fixture clamped with 3600 N of fail-safe force if shop air exhausts, ensuring the 3518 N push cycle does not drift unexpectedly.
Pallet Stopper
Locks a 250 mm stroke pallet stop pin solid in place during E-stops, resisting dynamic impacts without relying on live air pressure.
Is the Airtac BSE Clamp Standard Cylinder BSE80X250S the Right Cylinder?
Verify your suspended load needs less than the 3600 N static holding force. If you need less drive force, step down to the 63 mm bore, which pushes 1559 N at 0.5 MPa and holds 2200 N. If you need more, step up to the 100 mm bore, which pushes 3927 N at 0.5 MPa and holds 5500 N. Match your replacement by bore, 250 mm stroke, PT3/8 port, and the -S magnet option. For this 250 mm stroke, standard guide rails should support the rod to prevent side-load wear.
Quick checklist
- ✓ Load to hold ≤ 3600 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 BSE80X250S FAQ
The spring-applied collet clamps the rod instantly, providing a 3600 N bidirectional static hold with no live air. It is a fail-safe lock, not a dynamic brake, so engage it only after the rod stops.
Drive force at 0.5 MPa is 2513 N push and 2268 N pull. At 0.7 MPa, push is 3518 N, yielding a max 359 kgf. The separate static holding force of the lock is 3600 N.
