Airtac BSED Clamping Double Acting Cylinder BSED100X400S
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED100X400S 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, 400mm stroke, PT1/2 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED100X400S
The AirTAC BSED100X400S 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 force in both directions—delivering 3681 N each way at 0.5 MPa and 5153 N at 0.7 MPa. The rear rod is ideal for mounting external tooling, flags, or anti-rotation guides.
This 100 mm bore unit provides a bidirectional static holding force of 5500 N with no live air required. If pressure drops or an E-stop engages, the collet clamps the 25 mm rod to hold position safely. The lock uses a separate G1/8 release port, and the operating pressure is capped at 0.7 MPa. The -S option includes a magnet for CMSE reed and DMSE electronic 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 BSED100X400S 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 BSED100X400S Is Used
Overhead Lift Stations
Holds 5500 N against gravity drops during air loss, while the 5153 N both-way force drives heavy 100 mm tooling up and down.
Pallet Stopper Arms
Uses the rear rod for a cam flag; the collet locks the 25 mm rod securely to halt 400 mm pallet transfers without live air.
Multi-Position Machining
Equal both-way thrust positions heavy fixtures precisely, engaging the fail-safe lock during cutting cycles to resist 5500 N of force.
Is the Airtac BSED Clamping Double Acting Cylinder BSED100X400S the Right Cylinder?
Select this model when your application requires symmetric drive force and fail-safe mid-stroke holding. Ensure your load does not exceed the 5500 N static holding force. If you need less force, step down to the 80 mm bore (2268 N at 0.5 MPa, 3600 N hold); if you need more, step up to the 125 mm bore (5734 N at 0.5 MPa, 8600 N hold).
Engage the lock only after the rod stops, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 s. For this 400 mm stroke, use external guide rails to prevent side-load wear. Replacement requires matching the 100 mm bore, 400 mm stroke, PT1/2 port, and mounting style (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 BSED100X400S FAQ
It delivers 3681 N of drive force at 0.5 MPa and 5153 N at 0.7 MPa (max 525 kgf), equal in both directions. The integrated spring-applied rod lock provides a 5500 N static holding force with no live air.
The lock is a holding device, not a dynamic brake. Engage it only after the rod stops. To release, pressure-balance both piston sides via the PT1/2 cylinder ports, apply air to the G1/8 release port, and wait at least 0.5 s.
