About the Airtac BSED Clamping Double Acting Cylinder BSED50X150S
The AirTAC BSED50X150S 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 825 N each way at 0.5 MPa. The fail-safe collet mechanism delivers a 1400 N static holding force to secure loads instantly when air is removed.
This unit utilizes a separate G1/8 release port and operates reliably at 30-800 mm/s. Because it is an extruded aluminum profile cylinder, it offers clean ISO 15552 mounting interchangeability without external tie rods. The included -S magnet enables precise position sensing with CMSE reed or DMSE electronic sensors.
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 BSED50X150S 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 BSED50X150S Is Used
Symmetric Tool Transfer
Drives 825 N both ways to shuttle a machining fixture, using the rear rod for an anti-rotation flag while the 1400 N lock holds position during cutting.
Mid-Stroke Pallet Stop
Halts a conveyor indexing pallet at 150 mm stroke; the spring-applied collet clamps with 1400 N to prevent drift if compressed air drops.
Overhead Lift Hold
Raises a 50 kg jig with equal both-way force, engaging the fail-safe lock to maintain the load statically while ensuring balanced pressure for release.
Is the Airtac BSED Clamping Double Acting Cylinder BSED50X150S the Right Cylinder?
Select this 50 mm bore model when your application demands both symmetric thrust and reliable mid-stroke holding. Verify your load requires less than the 1400 N static holding capacity. If you need less force, the 40 mm bore offers 528 N at 0.5 MPa and 900 N holding; if you need more, the 63 mm bore provides 1402 N at 0.5 MPa and 2200 N holding.
Always 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 50 mm bore, 150 mm stroke, PT1/4 cylinder port, and your specific mounting option (Basic, LB, FA, or TC).
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 BSED50X150S FAQ
The double-rod drive force is 825 N at 0.5 MPa and 1154 N at 0.7 MPa (max 118 kgf), equal in both directions. The integrated spring-applied rod lock provides a 1400 N static holding force with no live air.
Release the lock only after both piston sides are pressure-balanced, ensuring the rod is not under load. Allow at least 0.5 seconds for the air to release the collet before moving the cylinder.
