Airtac BSED Clamping Double Acting Cylinder BSED100X250
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED100X250 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 5500 N in either direction if air is lost. Ø100mm bore, 250mm stroke, PT1/2 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED100X250
The AirTAC BSED100X250 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 3681 N each way at 0.5 MPa. The rear rod provides anti-rotation stability and allows mounting a flag or cam for external tracking.
This fail-safe collet lock clamps bidirectionally with a static holding force of 5500 N, maintaining position with zero live air. Operating pressure is capped at 0.7 MPa, and the lock uses a separate G1/8 release port. This SKU lacks 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 BSED100X250 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 BSED100X250 Is Used
Overhead Z-Axis Lifts
Holds vertical lifting platforms securely mid-stroke with 5500 N of fail-safe force, preventing drops if air pressure is lost.
Multi-Station Machining
Uses the equal 5153 N both-way thrust to index heavy fixtures, while the rear rod mounts a cam to confirm position.
Heavy Pallet Stopping
Arrests loaded pallets using the symmetric drive, then locks the 25mm rod instantly during emergency stops.
Is the Airtac BSED Clamping Double Acting Cylinder BSED100X250 the Right Cylinder?
Select this 100mm bore when your application requires both symmetric thrust and fail-safe holding. Verify your static load is 5500 N or less. If you need less force, the 80mm bore offers 2268 N at 0.5 MPa with a 3600 N hold; if you need more, the 125mm bore provides 5734 N at 0.5 MPa and an 8600 N hold.
Always engage the lock only after the rod stops moving, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds for the transition. For this 250mm stroke, ensure external guides support side loads to prevent binding. Replacement matches require the exact 100mm bore, 250mm stroke, PT1/2 port, and Basic, LB, FA, or TC mounting.
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 BSED100X250 FAQ
The spring-applied collet engages instantly, providing a bidirectional static holding force of 5500 N to maintain the rod position without live air. It is a static lock, not a dynamic brake, so it must engage only after the rod stops.
The equal both-way drive force is 3681 N at 0.5 MPa and 5153 N at 0.7 MPa, with a max drive of 525 kgf. The separate fail-safe rod lock provides a 5500 N static holding force, released via the G1/8 port.
