About the Airtac BSED Clamping Double Acting Cylinder BSED40X150S
The AirTAC BSED40X150S 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 thrust in both directions—about 528 N each way at 0.5 MPa and 739 N at 0.7 MPa. The rear rod provides a convenient mounting point for tooling, flags, or anti-rotation guides.
This fail-safe collet lock delivers a 900 N static holding force without requiring live air, securely clamping the 16 mm rod if pressure drops. It uses a dedicated G1/8 release port and operates safely within a 0.15-0.7 MPa pressure ceiling. Equipped with a magnet (-S), it supports CMSE reed and DMSE electronic sensors for precise position feedback.
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 BSED40X150S 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 BSED40X150S Is Used
Vertical Lift Stations
Uses the 900 N fail-safe collet lock to hold a 75 kgf vertical load securely in place during an E-stop or air loss, while the 739 N both-way drive ensures smooth up and down motion.
Dual-Tool Machining Jigs
Exploits the double-rod design to mount a secondary cam on the rear rod for timing, while the 528 N symmetric force drives the clamping action at 0.5 MPa.
Pallet Transfer Stops
Relies on the spring-applied lock to hold the 16 mm rod rigid against conveyor vibration, preventing drift when the 0.15-0.7 MPa operating air is shut off.
Is the Airtac BSED Clamping Double Acting Cylinder BSED40X150S the Right Cylinder?
Select this 40 mm bore model when an application demands both symmetric drive force and fail-safe holding up to 900 N. If your load requires less force, the 32 mm bore offers 345 N at 0.5 MPa with a 600 N holding capacity; if you need more, the 50 mm bore provides 825 N at 0.5 MPa and a 1400 N hold. Always verify your load does not exceed the 900 N static limit.
Remember that the lock is a static holding device, not a dynamic brake: engage it only after the rod fully stops, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds. For exact replacements, match the 150 mm stroke, PT1/4 cylinder port, and your preferred mounting (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 BSED40X150S FAQ
The integrated spring-applied collet immediately engages and clamps the rod, providing a 900 N static holding force to prevent movement. It is a fail-safe static lock, not a dynamic brake, so it should only engage after the rod has stopped.
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 static holding force of the lock is 900 N. Release requires pressure-balanced sides and at least 0.5 seconds via the G1/8 port.
