Airtac BSED Clamping Double Acting Cylinder BSED80X80S
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED80X80S 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, 80mm stroke, PT3/8 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED80X80S
The AirTAC BSED80X80S is a double-acting, double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A rod exits both ends, delivering equal drive force of 2268 N each way at 0.5 MPa and 3175 N at 0.7 MPa. The rear rod is ideal for mounting flags or cams while resisting rotation.
This fail-safe collet lock provides a bidirectional static holding force of 3600 N with no live air required. It engages only after the rod stops and releases via a separate G1/8 port when piston sides are pressure-balanced. The -S magnet supports CMSE reed and DMSE electronic sensors for precise position tracking.
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 BSED80X80S 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 BSED80X80S Is Used
Vertical Lift Stations
Lifts payloads using the equal 3175 N both-way force, engaging the 3600 N fail-safe collet lock to secure the load vertically if air pressure drops.
Dual-Tool Machining
Uses the rear exiting rod for a cam flag while providing symmetric 2268 N thrust at 0.5 MPa to machine parts from both directions accurately.
Pallet Indexing
Indexes heavy pallets with 324 kgf max drive force, locking the 25 mm rod instantly during E-stops to prevent conveyor drift.
Is the Airtac BSED Clamping Double Acting Cylinder BSED80X80S the Right Cylinder?
Choose the BSED80X80S when your application requires both symmetric thrust and reliable mid-stop holding. Verify your load does not exceed the 3600 N static holding force. If you need less force, the 63 mm bore offers 1402 N drive at 0.5 MPa and a 2200 N hold; stepping up to the 100 mm bore provides 3681 N drive at 0.5 MPa and a 5500 N hold.
Always engage the lock only after the rod stops, and allow at least 0.5 seconds for release once pressure is balanced. For exact replacements, match the 80 mm bore, 80 mm stroke, PT3/8 port, and your specific mounting choice (Basic, LB, FA, or TC).
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 BSED80X80S FAQ
The integrated spring-applied collet immediately clamps the rod, providing a 3600 N static holding force in both directions without live air. It is a fail-safe hold, not a dynamic brake, and should only engage after the rod stops.
The drive force is equal both ways at 2268 N at 0.5 MPa and 3175 N at 0.7 MPa, with a maximum drive of 324 kgf. The static holding force of the lock is 3600 N, which is separate from the drive force.
