Airtac BSED Clamping Double Acting Cylinder BSED40X150
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED40X150 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, 150mm stroke, PT1/4 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED40X150
The AirTAC BSED40X150 is a double-acting, double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. Because the annulus area is identical on both sides, it generates an equal drive force of 528 N each way at 0.5 MPa. A rod exits both ends, allowing the rear extension to mount a flag or cam while resisting rotational torque.
If air pressure drops or an E-stop trips, the internal collet clamps the 16 mm rod to provide a 900 N static fail-safe hold with zero live air. This unit uses a separate G1/8 release port and caps operating pressure at 0.7 MPa. It features adjustable air cushions at both ends and, lacking the -S magnet option, does not support position sensing on this SKU.
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 BSED40X150 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.

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 BSED40X150 Is Used
Transfer Line Stops
Uses the equal 528 N both-way force to index pallets, engaging its 900 N fail-safe collet to hold the workpiece securely during machining.
Symmetric Gripper Actuation
The double-rod design drives a centering gripper with identical push and pull forces, while the lock prevents drift when the system is idle.
Mid-Stroke Machining
Provides rigid anti-rotation via the rear rod for a tooling flag, locking the 16 mm rod with 900 N of static hold during clamping operations.
Is the Airtac BSED Clamping Double Acting Cylinder BSED40X150 the Right Cylinder?
Select this 40 mm bore when an application requires symmetric 528 N bi-directional force at 0.5 MPa alongside a 900 N fail-safe holding capacity. If your load requires less force, the 32 mm bore offers 345 N drive and 600 N holding; if you need more, step up to the 50 mm bore for 825 N drive and 1400 N holding. Always verify your static load is 900 N or below.
Engage the lock only after the rod completely stops, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds for the collet to retract. For exact replacement matching, confirm the 150 mm stroke, PT1/4 cylinder port, M12x1.25 rod thread, and your 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 BSED40X150 FAQ
The integrated spring-applied collet immediately clamps the rod, providing a 900 N static holding force to keep the load in place without live air. It is a fail-safe holding lock, not a dynamic brake, so it must only be engaged after the rod has stopped moving.
The BSED40X150 generates an equal drive force of 528 N at 0.5 MPa and 739 N at 0.7 MPa (max 75 kgf) in both directions. The static holding force of the lock is 900 N, and the operating speed range is 30-800 mm/s.
