About the Airtac BSED Clamping Double Acting Cylinder BSED40X1000
The AirTAC BSED40X1000 is a double-acting, double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. Because the rod exits both ends, it generates equal force and speed in both directions, delivering 528 N each way at 0.5 MPa. The fail-safe collet mechanism provides a 900 N static holding force, clamping the rod securely during pressure loss or E-stop events.
This 1000 mm stroke unit is a made-to-order configuration exceeding the 800 mm standard maximum. It features a 16 mm rod with an M12x1.25 thread, PT1/4 cylinder ports, and a dedicated G1/8 lock-release port. The extruded aluminum barrel avoids external tie rods, and this specific SKU is supplied without a magnet, meaning position sensors are not supported.
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 BSED40X1000 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 BSED40X1000 Is Used
Long-Stroke Vertical Lift
Raises and lowers heavy doors over 1000 mm using 528 N of both-way force, relying on the 900 N fail-safe collet to prevent gravity drops if air pressure is lost mid-cycle.
Pallet Stopper Gate
Actuates a 1-meter routing gate on a packaging line, utilizing the double-rod design for equal push/pull speed while the spring-applied lock holds the gate rigid during impact.
Extended Tool Transfer
Shifts a secondary machining tool along a 1000 mm axis, taking advantage of the rear rod exit for anti-rotation mounting flags and secure 900 N static positioning.
Is the Airtac BSED Clamping Double Acting Cylinder BSED40X1000 the Right Cylinder?
Select this model when your application requires symmetric drive force alongside fail-safe drop prevention. Verify your static load does not exceed the 900 N holding capacity. If you need less force, the adjacent 32 mm bore provides 345 N at 0.5 MPa with a 600 N hold; for heavier loads, the 63 mm bore offers 1402 N at 0.5 MPa and a 2200 N hold.
At 1000 mm, this long stroke demands external guide rails to prevent rod sagging and excessive side loads. Remember the lock is not a dynamic brake: engage it only after the rod stops moving, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds. Operating pressure is capped at 0.7 MPa.
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 BSED40X1000 FAQ
The double-rod design provides equal drive force in both directions: 528 N at 0.5 MPa and 739 N at 0.7 MPa, equating to a maximum drive force of 75 kgf. Separately, the integrated spring-applied rod lock provides a 900 N static holding force with no live air required.
You must apply air to the separate G1/8 release port only after the cylinder's piston sides are pressure-balanced. Because the lock is a static holding device rather than a dynamic brake, ensure the rod has completely stopped moving before engaging or releasing it, allowing at least 0.5 seconds for the collet to transition.
