Airtac BSED Clamping Double Acting Cylinder BSED80X25
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED80X25 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, 25mm stroke, PT3/8 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED80X25
The AirTAC BSED80X25 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 3175 N at 0.7 MPa. The extruded aluminum barrel has no external tie rods, ensuring a clean profile that accepts Basic, LB, FA, and TC mounts.
The fail-safe collet lock delivers a 3600 N static holding force with no live air required. It engages bidirectionally to secure the 25 mm stroke position if air pressure drops. This unit uses a dedicated G1/8 release port, and since this SKU lacks the -S magnet option, 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 BSED80X25 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 BSED80X25 Is Used
Overhead Z-Axis Lifts
Holds a 3600 N vertical load safely when air is lost, while the double-rod provides 3175 N of equal lift and lower force.
Machining Clamps
Secures heavy workpieces mid-cycle; the rear rod resists rotation and carries tooling or a mechanical flag.
Pallet Stops
Absorbs 324 kgf of dynamic conveyor mass symmetrically, locking the 25 mm stroke instantly during an E-stop.
Is the Airtac BSED Clamping Double Acting Cylinder BSED80X25 the Right Cylinder?
Select this 80 mm bore model when your application requires symmetric both-way force and mid-stroke holding. The lock safely resists loads up to 3600 N; if your load exceeds this, step up to the 100 mm bore (5153 N drive @0.7 MPa, 5500 N hold). If your load is under 2200 N, step down to the 63 mm bore (1962 N drive @0.7 MPa, 2200 N hold). Always 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. As a direct replacement, match the 80 mm bore, 25 mm stroke, PT3/8 cylinder 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 BSED80X25 FAQ
The spring-applied collet immediately clamps the rod, providing a 3600 N static holding force to prevent uncommanded movement. It is a fail-safe hold, not a dynamic brake, so engage it only after the rod stops.
The drive force is equal both ways: 2268 N at 0.5 MPa and 3175 N at 0.7 MPa (max 324 kgf). To release the 3600 N lock safely, apply pressure to the G1/8 release port only after both cylinder piston sides are pressure-balanced, allowing at least 0.5 seconds.
