Airtac BSED Clamping Double Acting Cylinder BSED40X700
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED40X700 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, 700mm stroke, PT1/4 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED40X700
The AirTAC BSED40X700 is a double-acting, double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A rod exits both ends, providing equal drive force of 528 N each way at 0.5 MPa. The integrated collet lock delivers a 900 N static holding force to secure the load safely with zero live air.
This unit features a PT1/4 cylinder port and a separate G1/8 lock-release port. The lock is a static holding device, not a dynamic brake; it must engage only after the rod stops and release when piston sides are pressure-balanced. This SKU has no magnet, meaning position sensing is not supported.
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 BSED40X700 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 BSED40X700 Is Used
Vertical Lift Jaws
Holds a 900 N vertical load safely mid-stroke if air drops, while the 528 N both-way force drives the gripper up and down evenly.
Pallet Transfer Stop
Uses the rear rod for a cam flag to trigger sensors, locking the 700mm stroke firmly in place during pallet loading.
Shuttle Mechanism
Equal push and pull forces of 528 N prevent speed asymmetry across the long 700mm travel, locking securely at either end.
Is the Airtac BSED Clamping Double Acting Cylinder BSED40X700 the Right Cylinder?
Select this 40mm bore model when an application requires symmetric both-way force and fail-safe holding up to 900 N. If your load exceeds 900 N, step up to the 50mm bore, which provides 825 N drive force at 0.5 MPa and 1400 N holding force. If you need less holding capacity, the 32mm bore offers 345 N drive force and 600 N holding force.
With a 700mm stroke, use a guide rail to prevent side-load damage to the seals and rod lock. To replace a unit, match the 40mm bore, 700mm stroke, PT1/4 port, and basic mounting setup. Always allow at least 0.5 seconds for the lock to engage or release after the rod stops.
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 BSED40X700 FAQ
The drive force is equal in both directions, providing 528 N at 0.5 MPa and 739 N at 0.7 MPa (max 75 kgf). The integrated fail-safe rod lock provides a separate static holding force of 900 N with no live air.
The lock is spring-applied and air-released via the G1/8 port. To release safely, ensure the piston sides are pressure-balanced, apply release pressure, and wait at least 0.5 seconds before moving the rod.
