Airtac BSED Clamping Double Acting Cylinder BSED50X200
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED50X200 combines a double-rod ISO 15552 cylinder — a Ø20mm rod out BOTH ends for equal force both directions — with an integrated spring-applied, air-released ROD LOCK that holds up to 1400 N in either direction if air is lost. Ø50mm bore, 200mm stroke, PT1/4 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED50X200
The AirTAC BSED50X200 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 delivers an equal drive force of 825 N each way at 0.5 MPa. A rod exits both ends, allowing the rear rod to carry a flag or cam while resisting rotation.
The fail-safe collet lock provides a 1400 N static holding force without consuming live air. If pressure drops or an E-stop trips, the rod is clamped securely at its position. This unit uses a PT1/4 cylinder port alongside a dedicated G1/8 lock-release port, and this specific SKU ships without a magnet, meaning no CMSE or DMSE position sensors can be fitted.
Double Rod + 1400 N Rod Lock (Ø50mm)
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 BSED50X200 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 M16×1.5 both ends. Mounting (BSED): Basic, LB, FA, TC. Port options: PT (standard) / G (BSPP); lock-release port is G1/8.
Theoretical Output Force (Ø50mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 825 N |
| 0.7 MPa (max) | 1155 N |
| Max drive (@0.7 MPa) | 118 kgf |
A rod exits both ends, so force is equal on extend and retract. Drive force is separate from the 1400 N static lock holding force. Size with a safety margin.

Where the Airtac BSED Clamping Double Acting Cylinder BSED50X200 Is Used
Vertical Lift Stations
Uses the 825 N equal both-way drive to raise and lower a 50 mm platform, engaging the 1400 N fail-safe collet lock during dwell cycles to prevent drift without live air.
Symmetric Machining Jigs
Clamps a workpiece from both sides using the dual rods; the rear rod resists rotational torque while the lock holds the 1154 N drive force steady during the cutting cycle.
Pallet Diverters
Transfers pallets equally in two directions with balanced speed, relying on the spring-applied lock to freeze the diverter arm safely if the 0.7 MPa air supply is interrupted.
Is the Airtac BSED Clamping Double Acting Cylinder BSED50X200 the Right Cylinder?
Select this 50 mm bore when an application requires both-way symmetric force and intermediate fail-safe holding up to 1400 N. If your load requires less holding, the 40 mm bore offers 528 N of drive force at 0.5 MPa and a 900 N static hold. For heavier loads, stepping up to the 63 mm bore provides 1402 N at 0.5 MPa and a 2200 N hold. Always ensure the load is fully stopped before engaging the lock, and allow at least 0.5 seconds for pressure to balance across both piston sides before releasing.
To match this cylinder for a replacement, confirm the 200 mm stroke, PT1/4 port thread, M16x1.5 rod-end thread, and the selected mounting style (Basic, LB, FA, or TC). As a double-rod design, the rear extension requires physical clearance for tooling or cams.
Quick checklist
- ✓ Need both symmetric force AND fail-safe hold?
- ✓ Load to hold ≤ 1400 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 BSED50X200 FAQ
The double-rod design provides an equal drive force of 825 N at 0.5 MPa and 1154 N at 0.7 MPa (a maximum of 118 kgf) in both directions. The integrated fail-safe rod lock provides a separate static holding force of 1400 N with no live air required.
The lock is spring-applied and air-released via the dedicated G1/8 port. To release it safely, ensure the rod has completely stopped moving, verify that pressure is balanced on both piston sides, apply 0.15-0.7 MPa to the release port, and allow at least 0.5 seconds before cycling.
