Airtac BSE Clamp Standard Cylinder BSE80X75S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE80X75S 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, 75mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE80X75S
The AirTAC BSE80X75S is a double-acting, single-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A collet clamps the Ø25 mm rod, delivering a 3600 N bidirectional static holding force with zero live air required. If pressure drops or an E-stop trips, the lock engages instantly to prevent drift. Operating pressure is capped at 0.7 MPa.
This 80 mm bore model features a PT3/8 cylinder port and a separate G1/8 release port. The lock is a holding device, not a dynamic brake; engage it only after the rod fully stops. The included -S magnet enables position sensing via CMSE reed or DMSE electronic sensors. SE mounting accessories fit this body, except for FTC.
Rod Lock — 3600 N Static Holding (Ø80mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE80X75S 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 BSE80X75S Is Used
Vertical Pallet Lift
Holds a 360 kg lifted pallet securely in place during air loss or E-stop, utilizing the full 3600 N fail-safe holding force to prevent uncontrolled drops.
Machine Tool Clamp
Maintains vise clamping pressure on a heavy workpiece when shop air is exhausted, ensuring the part stays fixed for safe operator loading.
Heavy Pallet Stopper
Acts as a rigid stop gate on a packaging line. The collet lock ensures the stopper remains extended against 3518 N of drive force even if the air supply is interrupted.
Is the Airtac BSE Clamp Standard Cylinder BSE80X75S the Right Cylinder?
Verify your load stays under the 3600 N static holding limit. If you need less force, step down to the 63 mm bore (1559 N push @0.5 MPa, 2200 N hold). If you need more, the 100 mm bore offers 3927 N push @0.5 MPa and 5500 N hold. Always balance pressures on both piston sides before unlocking, allowing at least 0.5 seconds for full release before commanding motion. When replacing, match the 80 mm bore, 75 mm stroke, PT thread, and magnet option. For this 75 mm stroke, side-load is minimal, but always use standard ISO 15552 guides for lateral forces.
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 BSE80X75S FAQ
The spring-applied collet immediately clamps the rod, delivering a 3600 N bidirectional static hold with no live air. This fail-safe mechanism prevents vertical load drift. It is a static hold, not a dynamic brake, so engage it only after the rod stops.
Drive forces are 2513 N push and 2268 N pull at 0.5 MPa, and 3518 N push at 0.7 MPa (max 359 kgf drive). The separate spring-applied rod lock provides a 3600 N static holding force. Never confuse the drive force with the holding force.
