Airtac BSED Clamping Double Acting Cylinder BSED80X160S
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED80X160S combines a double-rod ISO 15552 cylinder — a Ø25mm rod out BOTH ends for equal force both directions — with an integrated spring-applied, air-released ROD LOCK that holds up to 3600 N in either direction if air is lost. Ø80mm bore, 160mm stroke, PT3/8 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED80X160S
The AirTAC BSED80X160S is a double-acting, double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A rod exits both ends, providing equal drive force of 2268 N each way at 0.5 MPa and resisting rotation. The collet mechanism delivers a bidirectional static holding force of 3600 N with no live air required.
This fail-safe lock engages only after the rod stops and releases when piston sides are pressure-balanced via the separate G1/8 port. The extruded aluminum barrel has no external tie rods, and the included -S magnet supports CMSE reed and DMSE electronic sensors for precise position feedback.
Double Rod + 3600 N Rod Lock (Ø80mm)
A rod exits both ends for symmetric force and back-rod tooling, and a spring clamps the collet so the Airtac BSED Clamping Double Acting Cylinder BSED80X160S holds its position in both directions on air loss or E-stop. Apply 0.15–0.7 MPa to the G1/8 release port to unlock. Engage only after the rod has stopped (not a dynamic brake), and release only when both piston sides are pressure-balanced; allow ≥0.5 s for full release.

Theoretical Output Force (Ø80mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 2268 N |
| 0.7 MPa (max) | 3175 N |
| Max drive (@0.7 MPa) | 324 kgf |
A rod exits both ends, so force is equal on extend and retract. Drive force is separate from the 3600 N static lock holding force. Size with a safety margin.

Where the Airtac BSED Clamping Double Acting Cylinder BSED80X160S Is Used
Vertical Lift Stops
Holds vertical lifting platforms securely mid-stroke with 3600 N of fail-safe force, preventing drops during air loss while utilizing 3175 N of equal both-way drive.
Machining Fixtures
Clamps workpieces from both rod ends with 2268 N of symmetric force, using the rear rod for anti-rotation tooling while the lock holds position during cutting.
Pallet Transfer Gates
Indexes conveyor diverters with equal push and pull speeds, engaging the 3600 N collet lock to freeze the diverter arm precisely against passing loads.
Is the Airtac BSED Clamping Double Acting Cylinder BSED80X160S the Right Cylinder?
Select this 80mm bore model when your application requires symmetric both-way force and fail-safe holding up to 3600 N. If your load demands less hold, step down to the 63mm bore (1402 N drive at 0.5 MPa, 2200 N holding force). For heavier loads, step up to the 100mm bore (3681 N drive at 0.5 MPa, 5500 N holding force). Always verify your load is within the 3600 N limit.
Engage the lock only after the rod stops, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds for the transition. Operating pressure is capped at 0.7 MPa. For exact replacements, match the 160mm stroke, PT3/8 port, and Basic/LB/FA/TC mounting.
Quick checklist
- ✓ Need both symmetric force AND fail-safe hold?
- ✓ Load to hold ≤ 3600 N?
- ✓ Back-rod space for tooling/flag
- ✓ Lock engaged only when stopped
- ✓ G1/8 release-air line available
Installation & Safety Notes
- check Engage the lock only after the rod has stopped — not 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 Support both rod ends; avoid side load.
- check Use BSED mounting (Basic/LB/FA/TC).
Airtac BSED Clamping Double Acting Cylinder BSED80X160S FAQ
The integrated collet is spring-applied, so it clamps the rod automatically on air loss or E-stop, providing a bidirectional static holding force of 3600 N. It is a static lock, not a dynamic brake, and must engage only after the rod stops.
The double-rod drive force is equal both ways: 2268 N at 0.5 MPa and 3175 N at 0.7 MPa, with a maximum drive of 324 kgf. The separate fail-safe rod lock provides a static holding force of 3600 N.
