Airtac BSED Clamping Double Acting Cylinder BSED50X160S
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED50X160S 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, 160mm stroke, PT1/4 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED50X160S
The AirTAC BSED50X160S is a double-acting, double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A rod exits both ends, yielding equal drive force in both directions—about 825 N each way at 0.5 MPa. The extruded aluminum barrel has no external tie rods, ensuring clean, ISO 15552 dimensionally interchangeable mounting.
The integrated collet lock delivers a 1400 N static fail-safe holding force, gripping the Ø20 mm rod bidirectionally with zero live air. This makes it a true power-off holding device, completely distinct from the adjustable 30 mm air cushions at both ends. The -S magnet option supports CMSE reed and DMSE electronic sensors for precise position feedback.
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 BSED50X160S 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 BSED50X160S Is Used
Overhead Lift Stations
Holds a 1400 N vertical load securely in place during air loss or E-stops, while the 825 N both-way drive raises and lowers the tooling smoothly.
Indexing Assembly Platforms
Uses the rear exiting rod for anti-rotation stability and cam tracking, locking the 50 mm stage rigidly for precise component machining.
Pallet Transfer Stops
Provides 1154 N of equal push/pull force to position pallets, engaging the 1400 N collet lock to hold the assembly firmly during work.
Is the Airtac BSED Clamping Double Acting Cylinder BSED50X160S the Right Cylinder?
Select this 50 mm bore model when your application requires symmetric push/pull force alongside mid-stroke fail-safe holding. Verify your load requires holding at or below 1400 N. If you need less force, the 40 mm bore provides 528 N at 0.5 MPa and 900 N holding; if you need more, step up to the 63 mm bore for 1402 N at 0.5 MPa and 2200 N holding. Operating pressure is capped at 0.7 MPa.
The lock is a static holding device, not a dynamic brake. Engage it only after the rod stops, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds for the transition. When replacing, match the 160 mm stroke, PT1/4 cylinder port, and mounting style (Basic, LB, FA, or TC). For the 160 mm stroke, ensure adequate side-load support using external guides to prevent binding.
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 BSED50X160S FAQ
The spring-applied collet immediately clamps the rod, providing a 1400 N static bidirectional holding force without any live air. It is a fail-safe lock, not a dynamic brake, so it must be engaged only after the rod stops moving.
The double-rod design provides equal force both ways: 825 N at 0.5 MPa and 1154 N at 0.7 MPa (max 118 kgf). The static holding force of the lock is 1400 N. Operating speed is 30-800 mm/s, and the lock-release port is G1/8.
