Airtac BSED Clamping Double Acting Cylinder BSED40X75S
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED40X75S 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, 75mm stroke, PT1/4 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED40X75S
The AirTAC BSED40X75S is a double-acting, double-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A rod exits both ends, delivering equal force in both directions—about 528 N each way at 0.5 MPa. The rear rod can mount a flag or cam and naturally resists rotation.
If air pressure drops or an E-stop trips, the collet mechanism clamps the 16 mm rod to provide a 900 N static fail-safe hold without live air. The lock operates via a separate G1/8 release port, and the cylinder uses a PT1/4 port with 30 mm adjustable air cushions at both ends. The -S magnet option supports CMSE and DMSE 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 BSED40X75S 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 BSED40X75S Is Used
Vertical Lift Stations
Lifts light vertical loads with 528 N of equal both-way force and holds them safely mid-air with a 900 N fail-safe collet lock during air loss.
Pick-and-Place Gantries
Uses the double-rod design to mount a rear cam while providing symmetric 739 N drive force at 0.7 MPa for precise horizontal transfers.
Pallet Stops
Deploys a stopper blade on the front rod and a position flag on the rear rod, locking instantly with 900 N of static hold when E-stops activate.
Is the Airtac BSED Clamping Double Acting Cylinder BSED40X75S the Right Cylinder?
Select this 40 mm bore when an application needs both symmetric drive force and reliable mid-stroke holding. Verify your load requires 900 N or less of static holding force and 528 N of drive force at 0.5 MPa. If you need less force, the 32 mm bore offers 345 N of drive force and 600 N of holding force; if you need more, the 50 mm bore provides 825 N of drive force and 1400 N of holding force.
Always engage the lock only after the rod stops moving, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds for the transition. To replace this unit, match the 40 mm bore, 75 mm stroke, PT1/4 port, and -S magnet. Mounting options include Basic, LB, FA, and 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 BSED40X75S FAQ
The integrated rod lock is spring-applied and air-released. If air pressure drops below 0.15 MPa or the system trips an E-stop, the collet clamps the 16 mm rod, providing a 900 N static holding force to keep the load in place without live air.
The double-rod design provides equal force in both directions: 528 N at 0.5 MPa and 739 N at 0.7 MPa, with a maximum drive force of 75 kgf. This drive force is separate from the 900 N static holding force of the fail-safe rod lock.
