Airtac BSE Clamp Standard Cylinder BSE80X300
The AirTAC Airtac BSE Clamp Standard Cylinder BSE80X300 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, 300mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE80X300
The AirTAC BSE80X300 is a double-acting, single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. The lock delivers a 3600 N bidirectional static holding force to secure loads with zero live air. Operating pressure is capped at 0.7 MPa, and a separate G1/8 release port governs the collet mechanism.
This 80 mm bore unit runs at 30-800 mm/s and uses adjustable air cushions at both ends. The lock is strictly a static holding device, not a dynamic brake. It must engage only after the rod stops, and release requires balanced piston pressures with at least 0.5 s delay before motion.
Rod Lock — 3600 N Static Holding (Ø80mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE80X300 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.

Specifications follow the official AirTAC BSE datasheet. The lock uses the SE standard body; SE mounting accessories fit BSE except FTC. Port options: PT (standard) / G (BSPP); lock-release port is G1/8.
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 BSE80X300 Is Used
Vertical Pallet Lifts
Secures elevated pallets in packaging lines, preventing 3600 N loads from crashing down during sudden air loss or E-stop events.
Injection Molding Doors
Holds heavy safety guards open against gravity. The fail-safe collet locks instantly if plant air drops, protecting operators.
Pallet Stopper Arms
Maintains rigid stop positions on accumulating conveyors. The lock sustains 3600 N of impact pressure without drifting backward.
Is the Airtac BSE Clamp Standard Cylinder BSE80X300 the Right Cylinder?
Verify your suspended load is safely under the 3600 N holding force. If you need less holding power, step down to the 63 mm bore (1559 N push @0.5 MPa, 2200 N hold). For heavier demands, step up to the 100 mm bore (3927 N push @0.5 MPa, 5500 N hold). Always engage the lock only after the rod fully stops, and release it only when piston pressures are balanced.
This 300 mm stroke configuration requires attention to side loads. Use guide rails to prevent rod binding over extended travel. Match your exact replacement by confirming the PT3/8 cylinder port, M20x1.5 rod thread, and standard SE mounting accessories (excluding FTC). This specific SKU lacks a magnet, so position sensing is not available.
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 BSE80X300 FAQ
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). The separate static holding force of the rod lock is 3600 N.
The lock is spring-applied and fails safe, clamping the rod bidirectionally up to 3600 N. To release it, supply 0.15-0.7 MPa to the G1/8 port after balancing piston pressures, allowing at least 0.5 s before moving.
