About the Airtac BSED Clamping Double Acting Cylinder BSED40X1000S
The AirTAC BSED40X1000S 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 and speed in both directions—yielding about 528 N each way at 0.5 MPa. The rear rod can mount a flag or cam and helps resist rotation.
This fail-safe collet lock delivers a 900 N static holding force with no live air, clamping bidirectionally if pressure drops or an E-stop trips. The lock uses a separate G1/8 release port and is not a dynamic brake; engage it only after the rod stops, and release it only when piston sides are pressure-balanced, allowing at least 0.5 seconds. The -S magnet supports CMSE reed and DMSE electronic sensors.
Double Rod + 900 N Rod Lock (Ø40mm)
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 BSED40X1000S 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 M12×1.25 both ends. Mounting (BSED): Basic, LB, FA, TC. Port options: PT (standard) / G (BSPP); lock-release port is G1/8.
Theoretical Output Force (Ø40mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa (max) | 739 N |
| Max drive (@0.7 MPa) | 75 kgf |
A rod exits both ends, so force is equal on extend and retract. Drive force is separate from the 900 N static lock holding force. Size with a safety margin.

Where the Airtac BSED Clamping Double Acting Cylinder BSED40X1000S Is Used
Z-Axis Lift Stations
Holds a 900 N vertical load safely during air loss while the double-rod's 528 N equal both-way force drives precise up/down material handling.
Indexing Assembly Tables
The rear rod mounts a cam for position feedback, while the fail-safe collet locks the 1000mm stroke securely during E-stops.
Pallet Diverter Gates
Uses the equal both-way force to push and retract a diverter arm, engaging the 900 N static lock to hold the arm steady mid-stroke.
Is the Airtac BSED Clamping Double Acting Cylinder BSED40X1000S the Right Cylinder?
Select this 40mm bore double-rod cylinder when your application requires symmetric both-way drive and a fail-safe hold up to 900 N. If your load needs less force, the 32mm bore offers 345 N at 0.5 MPa and 600 N holding; if you need more, step up to the 50mm bore for 825 N at 0.5 MPa and 1400 N holding. Operating pressure is capped at 0.7 MPa.
Because this 1000mm stroke exceeds the 800mm standard, it is made-to-order and requires external guide rails to prevent side-load damage on the long rod. For a direct replacement, match the 40mm bore, 1000mm stroke, PT1/4 cylinder port, and your mounting choice (Basic, LB, FA, or TC).
Quick checklist
- ✓ Need both symmetric force AND fail-safe hold?
- ✓ Load to hold ≤ 900 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 BSED40X1000S FAQ
The integrated spring-applied collet engages automatically, providing a 900 N bidirectional static holding force to keep the rod at position. It is a fail-safe lock, not a dynamic brake, so engage it only after the rod stops moving.
The double-rod drive force is equal both ways: 528 N at 0.5 MPa and 739 N at 0.7 MPa (max 75 kgf). The fail-safe static holding force of the lock is 900 N. Release the lock via the G1/8 port only when both piston sides are pressure-balanced, allowing at least 0.5 seconds.
