Airtac BSE Clamp Standard Cylinder BSE80X160S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE80X160S 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, 160mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE80X160S
The AirTAC BSE80X160S is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A collet clamps the Ø25 mm rod, providing a 3600 N bidirectional static holding force with zero live air required to maintain the grip. Operating pressure is capped at 0.7 MPa, and the lock unlocks via a separate G1/8 port.
This fail-safe mechanism ensures the piston rod stays locked in both directions if air pressure drops or an E-stop is triggered. The lock is a holding device, not a dynamic brake; it must engage only after the rod stops and release only when piston pressures are balanced, allowing at least 0.5 s for full release. The -S magnet option enables position tracking with CMSE reed or DMSE electronic sensors.
Rod Lock — 3600 N Static Holding (Ø80mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE80X160S 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 BSE80X160S Is Used
Vertical Pallet Lifts
Holds a 360 kg vertical pallet hoist firmly in place during air loss, preventing uncontrolled drops while the 3518 N drive force handles the lifting cycle.
Overhead Machining Clamps
Secures heavy machining clamps on a multi-axis mill; the 3600 N collet lock prevents gravity back-driving if shop air is exhausted mid-cycle.
Pallet Stop Gates
Acts as a hard stop on an assembly conveyor; the fail-safe lock keeps the 25 mm rod extended against 80 mm bore drive force even during an emergency power cut.
Is the Airtac BSE Clamp Standard Cylinder BSE80X160S the Right Cylinder?
Verify your suspended load requires less than the 3600 N holding capacity. If you need less drive force, step down to the bore 63 model, which delivers 1559 N push at 0.5 MPa and a 2200 N hold. If you need more power, the bore 100 model provides 3927 N push at 0.5 MPa and a 5500 N hold. Always balance pressures before unlocking, and allow at least 0.5 s for release before commanding motion.
For exact replacements, match the 80 mm bore, 160 mm stroke, PT3/8 cylinder port, and the -S magnet. The extruded aluminum ISO 15552 body accepts SE mounting accessories except FTC. Because the stroke is under 300 mm, standard side-load risks are minimal, but always ensure rigid guidance for heavy tooling.
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 BSE80X160S FAQ
The spring-applied collet instantly clamps the rod, delivering a 3600 N bidirectional static hold. The cylinder will not drift, but the lock is not a dynamic brake; it must engage only after the rod has stopped.
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). This is separate from the 3600 N static holding force provided by the rod lock.
