Airtac BSE Clamp Standard Cylinder BSE80X250
The AirTAC Airtac BSE Clamp Standard Cylinder BSE80X250 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 BSE80X250
The AirTAC BSE80X250 is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It provides a 3600 N bidirectional static holding force with no live air, ensuring suspended loads stay put during an E-stop or pressure drop. Operating pressure is capped at 0.7 MPa.
This 80 mm bore unit features a 25 mm rod, an M20x1.5 rod-end thread, and PT3/8 cylinder ports. The lock uses a separate G1/8 release port and must engage only after the rod stops. This SKU has no magnet, so it does not support position sensing.
Rod Lock — 3600 N Static Holding (Ø80mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE80X250 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 (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 BSE80X250 Is Used
Vertical Lift Hold
Secures a 300 kg vertical machining center elevator in place during air loss, relying on the 3600 N static hold to prevent drift.
Pallet Stop Gate
Acts as a fail-safe stop for a heavy pallet conveyor, clamping the rod instantly if E-stop is hit and system pressure drops.
Tool Clamp Hold
Maintains a heavy stamping tool clamp locked in position, ensuring the 3518 N drive force is only applied when balanced and released.
Is the Airtac BSE Clamp Standard Cylinder BSE80X250 the Right Cylinder?
Verify your load requires 3600 N or less of holding force. If you need less, the 63 mm bore offers 1402 N pull at 0.5 MPa and a 2200 N hold. If you need more, the 100 mm bore provides 3927 N push at 0.5 MPa and a 5500 N hold. The lock engages only after the rod stops; release it only when piston pressures are balanced, allowing at least 0.5 s before moving. For this 250 mm stroke, guide the load to prevent excessive side-loading on the rod. SE mounting accessories fit this ISO 15552 body except FTC.
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 BSE80X250 FAQ
The drive force is 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, with a max drive of 359 kgf. The separate static holding force of the rod lock is 3600 N with no live air.
The spring-applied collet clamps the rod instantly, providing a 3600 N bidirectional fail-safe hold. To release it, supply air to the G1/8 port, ensure piston pressures are balanced, and wait at least 0.5 s before moving.
