Airtac BSED Clamping Double Acting Cylinder BSED80X450
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED80X450 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, 450mm stroke, PT3/8 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED80X450
The AirTAC BSED80X450 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 thrust in both directions at 2268 N each way at 0.5 MPa. The rear rod is ideal for mounting external tooling, flags, or anti-rotation guides.
This fail-safe unit provides a 3600 N static holding force via a bidirectional collet, securing the load instantly if air pressure drops. Operating pressure is capped at 0.7 MPa, and the lock uses a separate G1/8 release port. This SKU has no magnet, meaning position sensors are not supported.
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 BSED80X450 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 BSED80X450 Is Used
Overhead Z-Axis Lifts
Holds vertical loads securely with 3600 N of fail-safe force on air loss, while the 3175 N both-way drive ensures stable up and down positioning.
Multi-Station Machining
The double-rod design resists torsion during clamping, and the collet lock freezes the 450 mm stroke position during emergency stops.
Pallet Stop Gates
Uses the rear rod for cam activation while the front rod provides 2268 N of equal force to push and retract heavy pallet stops.
Is the Airtac BSED Clamping Double Acting Cylinder BSED80X450 the Right Cylinder?
Select this 80 mm bore model when an application demands symmetric drive force alongside a robust 3600 N fail-safe hold. If your load requires less force, the 63 mm bore offers 1402 N at 0.5 MPa with a 2200 N holding capacity. For heavier demands, the 100 mm bore provides 3681 N at 0.5 MPa and 5500 N of hold. Always verify your static load is under 3600 N.
Engage the lock only after the rod completely stops, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds. At 450 mm stroke, use a guide to manage side loads and prevent binding. Replacement parts must match the 80 mm bore, 450 mm stroke, PT3/8 port, and mounting style.
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 BSED80X450 FAQ
The integrated spring-applied collet clamps the rod instantly, providing a 3600 N static holding force without live air. It is a static lock, not a dynamic brake, so it must engage only after the rod stops.
The double-rod design provides equal drive force both ways: 2268 N at 0.5 MPa and 3175 N at 0.7 MPa, with a max drive of 324 kgf. The fail-safe rod lock provides a separate 3600 N static holding force.
