About the Airtac BSED Clamping Double Acting Cylinder BSED80X225S
The AirTAC BSED80X225S is a double-acting, double-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A Ø25 mm rod exits both ends, delivering equal push and pull force—about 2268 N each way at 0.5 MPa. The lock provides a 3600 N static fail-safe hold without requiring live air pressure.
This extruded aluminum body avoids external tie rods while offering bidirectional anti-rotation stability via the rear rod. The lock engages via a collet only after motion stops, using a dedicated G1/8 release port. Operating pressure is capped at 0.7 MPa, and the included -S magnet supports CMSE reed and DMSE electronic 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 BSED80X225S 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 BSED80X225S Is Used
Vertical Lift Station
Holds a 360 kg vertical load securely at 3600 N during air loss or E-stop, while the double-rod provides 2268 N of equal lifting and lowering force at 0.5 MPa.
Mid-Stroke Machining
Clamps a workpiece with the rear rod acting as an anti-rotation guide, using the collet lock to hold position against machining vibration without live air.
Pallet Stopper Arm
Extends a stopping flap with 3175 N of force and locks instantly upon E-stop to prevent pallet rollback, utilizing the double-rod design for both-way symmetry.
Is the Airtac BSED Clamping Double Acting Cylinder BSED80X225S the Right Cylinder?
Select this 80 mm bore when an application requires symmetric drive force and reliable fail-safe holding up to 3600 N. If your load demands less force, the 63 mm bore offers 1402 N at 0.5 MPa with a 2200 N hold; for heavier loads, the 100 mm bore provides 3681 N at 0.5 MPa and a 5500 N hold. Always verify the load stays below the 3600 N limit and engage the lock only after the rod stops. Release requires balancing pressure on both piston sides, allowing at least 0.5 seconds before moving. Since the 225 mm stroke is below 300 mm, side-load risks are moderate, but proper guiding is still recommended. Replacement matches must align with the PT3/8 port, 225 mm stroke, and -S magnet option.
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 BSED80X225S FAQ
The double-rod design provides equal drive force both ways: 2268 N at 0.5 MPa and 3175 N at 0.7 MPa (max 324 kgf). The integrated fail-safe rod lock provides a separate static holding force of 3600 N with no live air required.
The collet lock is spring-applied and air-released via a dedicated G1/8 port. Engage it only after the rod completely stops. To release safely, balance the pressure on both piston sides and apply unlock pressure, allowing at least 0.5 seconds before resuming motion.
