Airtac BSE Clamp Standard Cylinder BSE80X125
The AirTAC Airtac BSE Clamp Standard Cylinder BSE80X125 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, 125mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE80X125
The AirTAC BSE80X125 is a double-acting, single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A collet mechanism provides a 3600 N bidirectional fail-safe hold, securing the load in both directions if air is lost or an E-stop trips. Operating pressure is capped at 0.7 MPa, and the lock is controlled via a separate G1/8 release port.
This unit uses an extruded aluminum barrel without external tie rods and includes adjustable air cushions at both ends. The lock is a holding device, not a dynamic brake; it must be engaged only after the piston rod stops, and released only when pressures are balanced, allowing at least 0.5 seconds for full release before motion. This SKU ships without a magnet, so position sensing is not supported.
Rod Lock — 3600 N Static Holding (Ø80mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE80X125 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 BSE80X125 Is Used
Vertical Pallet Lift
Holds a raised pallet stack securely mid-stroke with 3600 N of fail-safe force, preventing a sudden crash if the supply air drops during conveyor transfer.
Machine Tool Clamp
Maintains vise pressure on an aluminum casting during an air outage, using the collet lock rather than the air cushion to prevent the part from shifting.
Safety Gate Stop
Keeps a heavy robotic cell guard fully extended during an E-stop event, locking the 25 mm rod instantly until pressure is restored and balanced.
Is the Airtac BSE Clamp Standard Cylinder BSE80X125 the Right Cylinder?
Verify your load requires a holding force of 3600 N or less. If your drive and hold requirements are lower, the adjacent 63 mm bore offers a 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 a 3927 N push at 0.5 MPa and a 5500 N hold. The lock engages via spring force and requires 0.15-0.7 MPa to unlock.
When ordering a replacement, match the 80 mm bore, 125 mm stroke, PT3/8 cylinder port, and desired mounting option. SE-compatible mounting accessories fit this cylinder except FTC. Because the stroke is 125 mm, ensure adequate guide support to prevent side-load wear on the rod and collet.
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 BSE80X125 FAQ
The lock is spring-applied and air-released, making it fail-safe. If air is lost, exhausted, or an E-stop trips, the collet clamps the rod and holds the load in both directions with a static holding force of 3600 N.
The drive force is 2513 N push and 2268 N pull at 0.5 MPa, and 3518 N push at 0.7 MPa (max 359 kgf drive). This is separate from the 3600 N static holding force. To release, apply 0.15-0.7 MPa to the G1/8 port only after the piston is stopped and pressures are balanced, allowing at least 0.5 seconds before moving.
