About the Airtac BSED Clamping Double Acting Cylinder BSED80X800
The AirTAC BSED80X800 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 a maximum of 3175 N at 0.7 MPa. The collet lock delivers a 3600 N bidirectional static holding force to secure loads safely with no live air.
This 80 mm bore unit features a 25 mm rod, M20x1.5 rod-end thread, PT3/8 cylinder ports, and a separate G1/8 lock-release port. The extruded aluminum barrel conforms to ISO 15552 dimensional interchangeability without external tie rods. Note that this specific SKU lacks the -S magnet option, so it does not support CMSE or DMSE position sensors.
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 BSED80X800 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 BSED80X800 Is Used
Vertical Lift Gates
Raises and lowers heavy access gates with 3175 N both-way drive, relying on the 3600 N fail-safe collet to prevent gravity drops during an air loss event.
Pallet Transfer Stops
Uses the twin rods to present and retract a physical stop block with equal speed both ways, locking firmly at 3600 N to hold moving pallets.
Heavy Component Indexing
Shifts large assemblies along an 800 mm path, using the rear rod for a cam return and the collet lock to freeze the payload during machining.
Is the Airtac BSED Clamping Double Acting Cylinder BSED80X800 the Right Cylinder?
Select this model when an application requires symmetric both-way force and a 3600 N fail-safe hold over an 800 mm stroke. If your load demands less force, the 63 mm bore provides 1402 N at 0.5 MPa with a 2200 N hold. For heavier needs, the 100 mm bore offers 3681 N at 0.5 MPa and a 5500 N hold. Always verify the actual load to hold is at or below 3600 N.
For this 800 mm stroke, use external guide rails to prevent side-load wear on the seals and barrel. To operate safely, engage the lock only after the rod fully stops, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds for the transition. When replacing, match the 80 mm bore, 800 mm stroke, PT thread, and basic 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 BSED80X800 FAQ
The drive force is equal both ways: 2268 N at 0.5 MPa and 3175 N at 0.7 MPa (max 324 kgf). The static fail-safe holding force of the integrated rod lock is 3600 N.
The spring-applied collet clamps automatically on air loss or E-stop, holding up to 3600 N. To release safely, pressure-balance both piston sides and apply air to the G1/8 release port, waiting at least 0.5 seconds before moving.
