About the Airtac BSED Clamping Double Acting Cylinder BSED100X225
The AirTAC BSED100X225 is a double-acting, double-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. Because the rod exits both ends, it delivers equal drive force in both directions—3681 N each way at 0.5 MPa and 5153 N at 0.7 MPa. The rear rod is ideal for mounting external flags or tooling while resisting rotational torque.
The fail-safe collet lock provides a 5500 N static holding force with no live air required. If air pressure drops or an E-stop trips, the rod is securely clamped at position. This unit features a PT1/2 cylinder port, a separate G1/8 lock-release port, and a 36 mm adjustable air cushion at both ends. This SKU ships without a magnet, so it does not support CMSE or DMSE position sensors.
Double Rod + 5500 N Rod Lock (Ø100mm)
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 BSED100X225 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 (Ø100mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 3682 N |
| 0.7 MPa (max) | 5154 N |
| Max drive (@0.7 MPa) | 526 kgf |
A rod exits both ends, so force is equal on extend and retract. Drive force is separate from the 5500 N static lock holding force. Size with a safety margin.

Where the Airtac BSED Clamping Double Acting Cylinder BSED100X225 Is Used
Heavy Machining Fixture
Clamps large castings with 5153 N of equal both-way force, while the 5500 N fail-safe lock holds the workpiece securely if shop air drops during a cut.
Pallet Lift Station
Raises and lowers heavy pallets using symmetric double-rod thrust, engaging the collet lock to hold the load mid-stroke without consuming continuous air.
Overhead Hoist Counterweight
Moves counterweights with equal extension and retraction speeds, relying on the 5500 N spring-applied hold to prevent drift during an E-stop event.
Is the Airtac BSED Clamping Double Acting Cylinder BSED100X225 the Right Cylinder?
Select this 100 mm bore when your application demands both symmetric thrust and fail-safe holding. Verify your load requires less than the 5500 N static holding force and less than the 5153 N drive force at 0.7 MPa. If you need less force, the 80 mm bore offers 2268 N drive force at 0.5 MPa and a 3600 N hold. If you need more, the 125 mm bore provides 5734 N drive at 0.5 MPa and an 8600 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 s for the transition. This is a static holding device, not a dynamic brake; use safety-rated controls for man-rated or overhead loads. When replacing a unit, match the 100 mm bore, 225 mm stroke, PT1/2 thread, and mounting choice (Basic, LB, FA, or TC).
Quick checklist
- ✓ Need both symmetric force AND fail-safe hold?
- ✓ Load to hold ≤ 5500 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 BSED100X225 FAQ
The drive force is equal both ways at 3681 N at 0.5 MPa and 5153 N at 0.7 MPa (max 525 kgf). The static fail-safe holding force of the integrated rod lock is 5500 N. Operating pressure is capped at 0.7 MPa.
The lock is spring-applied and air-released. If air pressure is lost, a collet clamps the rod immediately, providing up to 5500 N of static holding force. It is not a dynamic brake; you must engage it only after the rod stops and release it only when cylinder pressure is balanced.
