Airtac BSED Clamping Double Acting Cylinder BSED40X700S
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED40X700S 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 BSED40X700S
The AirTAC BSED40X700S 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 force of 528 N each way at 0.5 MPa, which is ideal for anti-rotation tooling or mounting rear flags.
The fail-safe collet delivers a 900 N static holding force without live air. It uses a separate G1/8 release port, and the operating pressure is capped at 0.7 MPa. The -S magnet supports CMSE reed and DMSE electronic sensors for mid-stroke positioning.
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 BSED40X700S 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 BSED40X700S Is Used
Vertical Lift Stations
Holds a 900 N vertical load safely during air loss, while the 528 N both-way drive ensures smooth ascent and descent.
Gripping Transfer Arms
Rear rod allows symmetrical tooling mounting, and the lock clamps the 700 mm stroke firmly during E-stops.
Pallet Stops
Provides equal push and pull force for indexing, engaging the 900 N collet to freeze the stopper when air drops.
Is the Airtac BSED Clamping Double Acting Cylinder BSED40X700S the Right Cylinder?
Select this 40 mm bore when you need 528 N of symmetric drive force and a 900 N fail-safe hold. If your load requires less force, step down to the 32 mm bore (345 N drive, 600 N hold). If you need more, step up to the 50 mm bore (825 N drive, 1400 N hold). Always verify your load is under 900 N when held.
Engage the lock only after the rod stops, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 s. For this 700 mm stroke, use a guide to prevent side-load wear. Replacement matches require the 40 mm bore, 700 mm stroke, PT1/4 port, and -S magnet.
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 BSED40X700S FAQ
The spring-applied collet engages instantly, providing a 900 N static holding force to keep the rod in position without live air. It is a fail-safe lock, not a dynamic brake.
The drive force is equal both ways: 528 N at 0.5 MPa and 739 N at 0.7 MPa (max 75 kgf). The static holding force is 900 N. Speed ranges from 30-800 mm/s.
