Airtac BSE Clamp Standard Cylinder BSE80X225S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE80X225S 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, 225mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE80X225S
The AirTAC BSE80X225S is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A collet clamps the 25 mm rod, delivering a 3600 N bidirectional static holding force with zero live air. Operating pressure is capped at 0.7 MPa, and the lock uses a separate G1/8 release port.
This fail-safe mechanism prevents drift on suspended loads during air loss or E-stops. The lock is a holding device, not a dynamic brake. You must engage it only after the rod stops, and release it only when piston pressures are balanced, allowing at least 0.5 s for full release. The -S option includes a magnet for CMSE and DMSE sensors.
Rod Lock — 3600 N Static Holding (Ø80mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE80X225S 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 BSE80X225S Is Used
Z-Axis Machining Head
Secures a 300 kg vertical spindle during an air pressure drop. The 3600 N collet lock holds the load safely, preventing a crash while the 3518 N drive handles the cutting feed.
Pneumatic Press Tool
Maintains clamping force on a stamping die if an E-stop trips. The fail-safe collet engages instantly, holding the tool steady without needing continuous 0.7 MPa air.
Pallet Diverter Gate
Locks a heavy routing gate in the extended position across a packaging line. The spring-applied lock resists conveyor vibration and holds the 25 mm rod firmly during line jams.
Is the Airtac BSE Clamp Standard Cylinder BSE80X225S the Right Cylinder?
Verify your load stays under the 3600 N holding force. If you need less holding or drive force, the 63 mm bore offers 1559 N push at 0.5 MPa and 2200 N hold. If you need more, the 100 mm bore gives 3927 N push at 0.5 MPa and 5500 N hold. Drive force here is 2513 N push and 2268 N pull at 0.5 MPa, peaking at 359 kgf at 0.7 MPa.
For this 225 mm stroke, side-load is moderate, but always guide the load to protect the rod seal. When replacing a unit, match the 80 mm bore, 225 mm stroke, PT3/8 cylinder port, and mounting. SE mounting accessories fit this body, except FTC brackets.
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 BSE80X225S FAQ
The lock is spring-applied and air-released. If air is lost or exhausted, a collet clamps the 25 mm rod, providing a 3600 N bidirectional static hold. It is a fail-safe holding device, 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, peaking at 359 kgf at 0.7 MPa. The static holding force is 3600 N. To release the lock, supply air to the G1/8 port, ensure piston pressures are balanced, and wait at least 0.5 s before moving.
