Airtac BSE Clamp Standard Cylinder BSE80X80
The AirTAC Airtac BSE Clamp Standard Cylinder BSE80X80 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, 80mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE80X80
The AirTAC BSE80X80 is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A collet clamps the Ø25 mm rod automatically, delivering a 3600 N bidirectional static holding force with zero live air. If pressure drops or an E-stop trips, the load stays exactly where it stopped.
Operating pressure is capped at 0.15-0.7 MPa, and unlocking requires 0.15-0.7 MPa supplied to a separate G1/8 release port. 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 before moving.
Rod Lock — 3600 N Static Holding (Ø80mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE80X80 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 BSE80X80 Is Used
Vertical Machining Center Loader
Holds a 300 kg vertical axis payload steady during loading. The 3600 N fail-safe collet locks instantly if air pressure drops, preventing the spindle loader from crashing down.
Injection Mold Clamp
Secures an injection mold tooling plate against 2268 N pull forces. The spring-applied lock maintains the grip even when the main 0.7 MPa air supply is exhausted for a tool change.
Pallet Line Diverter
Positions a heavy pallet diverter arm. The collet locks the 25 mm rod firmly in place during an emergency stop, ensuring the diverter does not drift into the main conveyor flow.
Is the Airtac BSE Clamp Standard Cylinder BSE80X80 the Right Cylinder?
Verify your load requires less than the 3600 N static holding force. If you need less holding and faster cycle speeds, the 63 mm bore offers 1559 N push at 0.5 MPa and a 2200 N hold. If you need more force, stepping up to the 100 mm bore provides 3927 N push at 0.5 MPa and a 5500 N hold. Always match replacement units by 80 mm bore, 80 mm stroke, PT3/8 port, and mounting style.
This SKU lacks a magnet, so it has no position sensing; add an -S suffix if you need CMSE or DMSE sensors. SE mounting accessories fit this body perfectly except FTC. Engage the lock only when the rod is fully stopped to prevent collet damage.
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 BSE80X80 FAQ
On air loss, the spring-applied collet clamps the rod for a 3600 N fail-safe hold. The drive forces are 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 lock holds; the air drives.
Apply 0.15-0.7 MPa to the separate G1/8 release port, but only after the pressures on both sides of the piston are balanced. Allow at least 0.5 seconds for the collet to fully retract before sending motion commands to prevent dynamic braking damage.
