About the Airtac BSED Clamping Double Acting Cylinder BSED80X225
The AirTAC BSED80X225 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 force and speed in both directions—about 2268 N each way at 0.5 MPa. The rear rod can carry tooling or a flag while resisting rotation.
The fail-safe collet lock provides a 3600 N static holding force with no live air. If pressure drops or an E-stop trips, the rod is held at position. Note this is a static lock, not a dynamic brake; engage it only after the rod stops. This SKU has no magnet, so position sensing is unavailable.
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 BSED80X225 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 BSED80X225 Is Used
Vertical Lift Hold
Lifts a 300 kg vertical stage with 3175 N both-way drive and locks it safely mid-stroke with 3600 N of static holding force during an E-stop.
Pallet Stopper
Halts heavy pallets using the front rod while the rear rod trips a flag; the 3600 N fail-safe collet prevents any drift on air loss.
Dual-Tool Machining
Machines parts from both ends using equal 2268 N force at 0.5 MPa, relying on the anti-rotation double-rod body for stable tooling alignment.
Is the Airtac BSED Clamping Double Acting Cylinder BSED80X225 the Right Cylinder?
Choose this 80 mm bore when you need symmetric both-way drive (3175 N at 0.7 MPa) and a 3600 N fail-safe hold. If your load is lighter, the 63 mm bore offers 1402 N drive force and 2200 N holding force. For heavier loads, the 100 mm bore provides 3681 N drive force and 5500 N holding force. Always verify your load is within the 3600 N holding limit. Engage the lock only after the rod stops, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds. When replacing, match the 80 mm bore, 225 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 BSED80X225 FAQ
The spring-applied collet immediately clamps the rod, providing a 3600 N bidirectional static holding force to keep the load in place. It is a fail-safe holding lock, not a dynamic brake, so it must only engage after the rod has stopped moving.
The BSED80X225 delivers equal both-way drive force of 2268 N at 0.5 MPa and 3175 N at 0.7 MPa (max 324 kgf). The static holding force of the lock is 3600 N. It operates at speeds of 30-800 mm/s with a PT3/8 cylinder port and a G1/8 lock-release port.
