About the Airtac BSED Clamping Double Acting Cylinder BSED50X100
The AirTAC BSED50X100 is a double-acting, double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A rod exits both ends, delivering equal force and speed in both directions—about 825 N each way at 0.5 MPa. The rear rod is ideal for mounting external tooling, flags, or cams while resisting rotation.
If air pressure drops or an E-stop trips, the internal collet clamps the rod instantly, providing a 1400 N bidirectional static holding force with no live air. This fail-safe 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. This SKU has no magnet (-S omitted), so it does not support CMSE or DMSE position 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 BSED50X100 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 BSED50X100 Is Used
Vertical Lift Stations
Holds a 1400 N vertical load securely during air loss. The double-rod design ensures 825 N of equal lifting and lowering force at 0.5 MPa for smooth vertical cycling.
Multi-Tool Machining
Uses the rear exiting rod to mount a secondary flag or cam. The collet locks the 100 mm stroke position instantly when the machining cycle halts.
Pallet Transfer Stops
Provides a rigid, anti-rotation stop for pallets. The fail-safe lock maintains position even if the 0.7 MPa air supply drops, preventing drift.
Is the Airtac BSED Clamping Double Acting Cylinder BSED50X100 the Right Cylinder?
Select this 50 mm bore model when you need both symmetric drive force and fail-safe positioning. Verify your load requires holding at or below 1400 N. If your application needs less force, the 40 mm bore provides 528 N at 0.5 MPa and 900 N of hold; if you need more, step up to the 63 mm bore, which yields 1402 N at 0.5 MPa and 2200 N of hold. Operating pressure is capped at 0.7 MPa, distinct from the 1.5 MPa proof rating. The cylinder uses a PT1/4 port, while the lock-release port is always G1/8. For safety-rated or man-rated overhead loads, do not rely on the lock alone—use external safety controls. At 100 mm stroke, side-load is minimal, but always guide the load to prevent rod 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 BSED50X100 FAQ
The drive force is equal both directions: 825 N at 0.5 MPa and 1154 N at 0.7 MPa (max 118 kgf). The integrated spring-applied rod lock provides a static holding force of 1400 N with no live air.
The lock is spring-applied and air-released. To release it safely, first pressure-balance both piston sides of the cylinder, then apply air to the separate G1/8 release port. Allow at least 0.5 seconds for the collet to disengage before moving the rod.
