Airtac BSE Clamp Standard Cylinder BSE80X500S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE80X500S 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, 500mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE80X500S
The AirTAC BSE80X500S is a double-acting ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A collet clamps the Ø25 mm rod automatically, providing a bidirectional fail-safe holding force of 3600 N without requiring live air. Operating pressure is capped at 0.7 MPa.
This model includes a -S magnet for CMSE reed and DMSE electronic position sensing. The lock uses a separate G1/8 release port and must only engage after the piston stops. The adjustable air cushions on both ends smooth out strokes, but the collet lock is the sole device responsible for static holding.
Rod Lock — 3600 N Static Holding (Ø80mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE80X500S 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 | — |

Where the Airtac BSE Clamp Standard Cylinder BSE80X500S Is Used
Automated Storage Lifts
Holds a 350 kg vertical carriage load firmly in place during E-stop or pressure loss, relying on the 3600 N collet clamp to prevent gravity-driven drops.
Press Tool Clamping
Secures heavy stamping dies on overhead cranes; the fail-safe lock engages the moment air is exhausted, keeping the 3518 N drive load locked mid-cycle.
Pallet Stop Gates
Maintains a rigid stop position on high-speed packaging lines, using the spring-applied collet to stay locked even if the plant air supply fails completely.
Is the Airtac BSE Clamp Standard Cylinder BSE80X500S the Right Cylinder?
Verify your suspended load stays below the 3600 N static holding limit. If your drive requirement is lower, the 63 mm bore provides 1559 N push at 0.5 MPa and 2200 N holding force. For heavier setups, the 100 mm bore offers 3927 N push at 0.5 MPa and 5500 N holding force. At 500 mm stroke, use guide rails to prevent side-load wear on the seals.
To release the lock safely, balance air pressure on both sides of the piston first, then supply air to the G1/8 release port. Always allow at least 0.5 seconds for full release before commanding movement. This cylinder uses a PT3/8 port, M20x1.5 rod thread, and accepts all SE mounting accessories except FTC.
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 BSE80X500S FAQ
The spring-applied collet instantly clamps the rod, delivering a 3600 N bidirectional static holding force to prevent drift. It is a fail-safe hold, not a dynamic brake; the rod must be completely stopped before engagement. For man-rated or overhead loads, use separate safety-rated controls.
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At the 0.7 MPa operating ceiling, push is 3518 N (max drive 359 kgf). The separate static holding force of the rod lock is 3600 N.
