Airtac BSED Clamping Double Acting Cylinder BSED40X160
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED40X160 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, 160mm stroke, PT1/4 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED40X160
The AirTAC BSED40X160 is a double-acting, double-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A rod exits both ends, providing equal drive force in both directions—about 528 N each way at 0.5 MPa. The rear rod can carry a flag or cam and resists rotation. The fail-safe collet clamps bidirectionally, delivering a 900 N static holding force with no live air required.
This unit features a 40 mm bore, 160 mm stroke, a 16 mm rod, and an M12x1.25 rod-end thread. The cylinder port is PT1/4, while the lock-release uses a separate G1/8 port. Operating pressure is capped at 0.7 MPa, and adjustable air cushions at both ends absorb impact. This SKU has no magnet, so CMSE or DMSE position sensors cannot be used.
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 BSED40X160 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 BSED40X160 Is Used
Vertical Lift Jig
Holds a 900 N vertical load safely in place during an air loss or E-stop, while the 528 N both-way drive raises and lowers the jig smoothly.
Shuttle Transfer
Equal push and pull force of 528 N at 0.5 MPa moves a shuttle both directions, with the fail-safe collet locking the rod when the cycle pauses.
Indexing Clamp
The rear rod carries a cam for timing, and the spring-applied lock secures the 40 mm bore position securely against vibration.
Is the Airtac BSED Clamping Double Acting Cylinder BSED40X160 the Right Cylinder?
Select this 40 mm bore model when your application demands both symmetric force and fail-safe holding. Verify your load does not exceed the 900 N static holding force. If you need less drive force, the 32 mm bore offers 345 N at 0.5 MPa and a 600 N hold; if you need more, step up to the 50 mm bore, which provides 825 N at 0.5 MPa and a 1400 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. For a direct replacement, match the 160 mm stroke, PT1/4 port, and 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 BSED40X160 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.
The equal both-way drive force is 528 N at 0.5 MPa and 739 N at 0.7 MPa (max 75 kgf). The static holding force of the rod lock is 900 N. Always release the lock when both sides are pressure-balanced, allowing at least 0.5 seconds.
