Airtac BSED Clamping Double Acting Cylinder BSED40X200S
The AirTAC BSED Clamping Double Acting Cylinder BSED40X200S 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, 200mm stroke, PT1/4 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED40X200S
The AirTAC BSED40X200S 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 thrust and pull forces of 528 N each way at 0.5 MPa. The rear rod is ideal for mounting flags or cam actuators while resisting rotational torque.
Its bidirectional fail-safe collet delivers a 900 N static holding force with zero live air required. Operating pressure is capped at 0.7 MPa, and the lock releases via a dedicated G1/8 port. The -S magnet option enables position sensing with CMSE reed or DMSE electronic 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 BSED40X200S 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 BSED40X200S Is Used
Vertical Lift Jigs
Secures elevated tooling plates with 900 N of fail-safe holding force during air loss, while the double-rod design provides 528 N of balanced up and down drive force.
Reciprocating Shutters
Drives horizontal gates equally in both directions with 528 N force, using the rear rod for external flag mounting and locking the assembly mid-stroke.
Pick-and-Place Arms
Resists payload rotation via the dual-rod structure and halts the arm safely with a spring-applied collet that holds 900 N without continuous air.
Is the Airtac BSED Clamping Double Acting Cylinder BSED40X200S the Right Cylinder?
Select this 40mm bore model when your application requires symmetric 528 N force both ways alongside a 900 N fail-safe holding capacity. If your load requires less force, the 32mm bore offers 345 N drive force and 600 N holding. If you need more, the 50mm bore provides 825 N drive and 1400 N holding. Always verify your static load is 900 N or less.
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. When replacing, match the 40mm bore, 200mm stroke, PT1/4 cylinder port, and -S magnet. For strokes of 300mm or longer, add an external guide to prevent side-load binding.
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 BSED40X200S FAQ
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 fail-safe holding force of the integrated rod lock is 900 N.
The spring-applied collet clamps the rod automatically, providing a 900 N bidirectional static hold with no live air. It is not a dynamic brake; engage it only after the rod stops, and release it only when both sides are pressure-balanced.
