Airtac BSED Clamping Double Acting Cylinder BSED40X80
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED40X80 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, 80mm stroke, PT1/4 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED40X80
The AirTAC BSED40X80 is a double-acting, double-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. Because two rods exit the body, the drive force is perfectly symmetrical, delivering 528 N each way at 0.5 MPa. The fail-safe collet lock provides a 900 N static holding force with zero live air required.
This unit features a 16 mm rod with an M12x1.25 thread, PT1/4 cylinder ports, and a separate G1/8 lock-release port. The extruded aluminum barrel carries no external tie rods, yielding a clean ISO 15552 mounting interface. This specific SKU lacks a magnet, so it does not support CMSE or DMSE position sensing.
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 BSED40X80 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 BSED40X80 Is Used
Vertical Lift Gates
Holds an overhead 900 N load securely mid-stroke if air pressure drops, while the 528 N both-way force drives the gate up and down with equal speed.
Symmetric Transfer Chuck
Uses the equal push and pull force to clamp parts from either direction, relying on the rear rod for anti-rotation stability during machining.
Pallet Stop Arm
Stops moving pallets using the 739 N maximum drive force, then drops air to engage the 900 N collet lock and hold the arm rigid.
Is the Airtac BSED Clamping Double Acting Cylinder BSED40X80 the Right Cylinder?
Select this 40 mm bore model when your application requires symmetric push-pull force and mid-range fail-safe holding. Verify your static load is at or below the 900 N holding capacity. If you need less 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 for 825 N at 0.5 MPa and a 1400 N hold.
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 transition. When replacing a unit, match the 80 mm stroke, PT1/4 port, and your required mounting style (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 BSED40X80 FAQ
The integrated collet lock is spring-applied, so it instantly clamps the rod with a 900 N static holding force when air is lost or an E-stop trips. The lock is bidirectional and requires no live air to maintain the hold.
The BSED40X80 delivers 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 fail-safe holding force of the lock is 900 N.
