Airtac BSE Clamp Standard Cylinder BSE80X80S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE80X80S 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 BSE80X80S
The AirTAC BSE80X80S is a double-acting, single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A collet clamps the Ø25 mm rod automatically, providing a bidirectional static holding force of 3600 N with zero live air required. Operating pressure for both the drive and the lock is capped at 0.7 MPa, and the lock unlocks via a dedicated G1/8 port.
This 80 mm bore unit includes a magnet for position sensing with CMSE reed or DMSE electronic sensors. The lock is a holding device, not a dynamic brake; it must be engaged only after the piston stops, and released only when cylinder pressures are balanced, allowing at least 0.5 s before motion. Standard 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 BSE80X80S 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 BSE80X80S Is Used
Vertical Machining Center Lift
Secures a 350 kg Z-axis machining head during an E-stop. The 3600 N collet lock holds the load bidirectionally without live air, preventing a crash, while the 2513 N drive handles the axis positioning.
Pneumatic Press Tooling
Maintains a clamping fixture safely in place on a forming press if air pressure drops. The fail-safe collet locks the 80 mm rod instantly, while the DMSE electronic sensor tracks exact clamping position.
Pallet Stacker Diverter
Holds a heavy diverter arm rigidly in place on a packaging conveyor during air loss. The 3600 N holding force prevents the arm from slipping, while the 3518 N push force at 0.7 MPa drives the stroke.
Is the Airtac BSE Clamp Standard Cylinder BSE80X80S the Right Cylinder?
Select this 80 mm bore model if your suspended load requires up to 3600 N of fail-safe holding force. If your load is lighter, the 63 mm bore offers a 0.5 MPa push of 1559 N and a 2200 N hold; if heavier, the 100 mm bore provides a 0.5 MPa push of 3927 N and a 5500 N hold. The 80 mm drive yields 2513 N push at 0.5 MPa and 359 kgf max drive at 0.7 MPa.
When ordering a replacement, verify the 80 mm stroke, PT3/8 cylinder port, and the -S magnet option. Always engage the lock only after the rod fully stops, and release it only when pressures are balanced. For this 80 mm stroke, side-load is minimal, but ensure standard guide rails support external loads.
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 BSE80X80S FAQ
The drive force is 2513 N push and 2268 N pull at 0.5 MPa, and 3518 N push at 0.7 MPa, equating to 359 kgf max drive. The separate spring-applied rod lock provides a 3600 N bidirectional static holding force with no live air.
The lock is spring-applied and air-released via a dedicated G1/8 port. You must engage it only after the rod stops moving, and release it only when pressures on both sides of the piston are balanced. Always allow at least 0.5 seconds for full release before commanding motion.
