Airtac BSED Clamping Double Acting Cylinder BSED40X600
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED40X600 combines a double-rod ISO 15552 cylinder — a Ø16mm rod out BOTH ends for equal force both directions — with an integrated spring-applied, air-released ROD LOCK that holds up to 900 N in either direction if air is lost. Ø40mm bore, 600mm stroke, PT1/4 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED40X600
The AirTAC BSED40X600 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 force and speed in both directions—528 N each way at 0.5 MPa and 739 N at 0.7 MPa. The rear rod can carry tooling or a flag cam and resists rotation.
This unit provides a bidirectional fail-safe holding force of 900 N with no live air required. If pressure drops or an E-stop trips, the collet clamps the rod to maintain position. The lock uses a separate G1/8 release port, and operating pressure is capped at 0.7 MPa. This SKU has no magnet, so position sensing is 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 BSED40X600 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 BSED40X600 Is Used
Overhead Lift Stations
Holds a 900 N vertical load mid-stroke if air is lost, while the 739 N both-way drive raises and lowers the assembly.
Pallet Indexing Stops
The double-rod extends and retracts a stopper blade at equal speed, locking the 16mm rod instantly on E-stop.
Symmetric Tooling Transfer
Rear-rod end mounts a flag cam for synchronized timing, while the front rod shifts 600mm strokes with matched force.
Is the Airtac BSED Clamping Double Acting Cylinder BSED40X600 the Right Cylinder?
Select this 40mm bore when an application requires symmetric 739 N drive force alongside fail-safe holding up to 900 N. If your load exceeds 900 N, step up to the 50mm bore (1154 N drive, 1400 N hold). If you need less force, step down to the 32mm bore (483 N drive, 600 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 seconds. With a 600mm stroke, ensure external guides support side loads to prevent binding. Replacement matches require PT1/4 ports, 16mm rod, M12x1.25 thread, and 30mm cushions.
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 BSED40X600 FAQ
The integrated spring-applied collet clamps engages immediately, providing a 900 N static holding force to keep the rod at position. It is a fail-safe lock, not a dynamic brake, so it must engage only after the rod stops moving.
The double-rod design delivers equal force both ways: 528 N at 0.5 MPa and 739 N at 0.7 MPa, with a maximum drive of 75 kgf. The separate fail-safe rod lock provides a 900 N static holding force.
