Airtac BSE Clamp Standard Cylinder BSE80X150S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE80X150S 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, 150mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE80X150S
The AirTAC BSE80X150S is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It delivers a 3600 N bidirectional static holding force with zero live air, ensuring suspended loads remain exactly where they stopped if pressure drops or an E-stop trips. Operating pressure is capped at 0.7 MPa.
This 80 mm bore, 150 mm stroke unit features a -S magnet for CMSE reed or DMSE electronic sensors. The lock uses a separate G1/8 release port and a clamping collet mechanism, completely distinct from the 36 mm adjustable air cushions at both ends. SE-compatible mounting accessories fit this body, excluding FTC.
Rod Lock — 3600 N Static Holding (Ø80mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE80X150S 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 BSE80X150S Is Used
Vertical Machining Center
Holds a 300 kg Z-axis spindle carriage mid-stroke. The 3600 N fail-safe collet prevents a crash drop during a sudden air loss, while the 3518 N drive force handles the machining feed.
Pallet Divider Gate
Acts as a powered stop on a heavy packaging line. If E-stop is hit, the spring-applied lock keeps the 150 mm extended rod rigid against 2500 N of pallet impact force without drifting.
Injection Mold Tooling
Clamps a heavy mold half in position. The collet lock maintains the exact 150 mm extension against gravity when the main 0.7 MPa air supply is exhausted for tool changes.
Is the Airtac BSE Clamp Standard Cylinder BSE80X150S 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 push 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. Always engage the lock only after the rod fully stops, and release it only when piston pressures are balanced, allowing at least 0.5 s before moving. To replace, match the 80 mm bore, 150 mm stroke, PT3/8 porting, and -S magnet option.
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 BSE80X150S FAQ
The integrated rod lock is spring-applied and fails safe. On air loss, the clamping collet engages the 25 mm rod instantly, providing a 3600 N bidirectional static hold. It is not a dynamic brake, so engage it only after the rod stops.
The drive forces are 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, with a maximum drive of 359 kgf. The separate static holding force from the rod lock is 3600 N. Release the lock via the G1/8 port only when pressures are balanced.
