Airtac BSED Clamping Double Acting Cylinder BSED80X80
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED80X80 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 BSED80X80
The AirTAC BSED80X80 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 in both directions at 2268 N (0.5 MPa) and 3175 N (0.7 MPa). The rear rod is ideal for mounting secondary tooling, flags, or anti-rotation guides.
This fail-safe lock delivers a 3600 N bidirectional static holding force with no live air required. The lock uses a separate G1/8 release port and operates at 0.15-0.7 MPa. Note that this SKU is supplied without a magnet (-S omitted), meaning no CMSE or DMSE position sensors can be fitted.
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 BSED80X80 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.

Specifications follow the official AirTAC BSED datasheet. Rod thread M20×1.5 both ends. Mounting (BSED): Basic, LB, FA, TC. Port options: PT (standard) / G (BSPP); lock-release port is G1/8.
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 BSED80X80 Is Used
Z-Axis Lift Stops
Holds a 3600 N vertical load safely in place during air loss or E-stop, while the double-rod design provides equal 3175 N lifting and lowering force.
Symmetric Machining Jig
Clamps parts from both ends using the dual rods, delivering identical 2268 N force at 0.5 MPa for balanced machining operations.
Pallet Mid-Stream Arrest
Uses the 324 kgf max drive to position heavy conveyor pallets, engaging the 3600 N collet lock to hold them securely during processing.
Is the Airtac BSED Clamping Double Acting Cylinder BSED80X80 the Right Cylinder?
Select this 80mm bore when your application demands symmetric both-way force and a robust fail-safe hold up to 3600 N. If your load requires less force, step down to the 63mm bore (1402 N at 0.5 MPa, 2200 N holding force). For heavier loads, step up to the 100mm bore (3681 N at 0.5 MPa, 5500 N holding force). Always verify your static load is at or below 3600 N.
Engage the lock only after the rod completely stops moving, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds for the transition. When replacing a unit, match the 80mm bore, 80mm stroke, PT3/8 cylinder port, and mounting style (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 BSED80X80 FAQ
The integrated spring-applied collet immediately clamps the rod, providing a 3600 N bidirectional static holding force to prevent movement. It is a fail-safe lock, not a dynamic brake, so it must be engaged only after the rod stops.
The BSED80X80 provides equal both-way drive force of 2268 N at 0.5 MPa and 3175 N at 0.7 MPa (max 324 kgf). The fail-safe rod lock provides a separate 3600 N static holding force.
