About the Airtac BSED Clamping Double Acting Cylinder BSED50X1000
The AirTAC BSED50X1000 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 at 825 N each way at 0.5 MPa. The rear rod is ideal for mounting flags or cams and naturally resists rotation.
This fail-safe collet lock provides a 1400 N static holding force without requiring live air. If pressure drops or an E-stop trips, the rod clamps securely. It engages only after the rod stops and releases via the dedicated G1/8 port when piston sides are pressure-balanced, requiring at least 0.5 seconds.
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 BSED50X1000 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 BSED50X1000 Is Used
Elevator Stage Holding
Lifts a 90 kg vertical platen with 825 N both-way force and holds it securely mid-air with the 1400 N fail-safe collet during an air loss event.
Symmetric Transfer Unit
Drives a dual-sided pick-and-place carriage at equal speeds and forces in both directions, using the rear exiting rod for a cam follower.
Z-Axis Machining Stop
Positions a tooling head precisely along a 1000 mm travel and locks the 1400 N load immediately upon cylinder stop to prevent drift during operation.
Is the Airtac BSED Clamping Double Acting Cylinder BSED50X1000 the Right Cylinder?
Select this 50 mm bore when you need 825 N of symmetric thrust at 0.5 MPa alongside a 1400 N static hold. If your load requires less force, the 40 mm bore offers 528 N drive and 900 N holding; if you need more, step up to the 63 mm bore for 1402 N drive and 2200 N holding. Always verify your load is under 1400 N for safe locking.
At 1000 mm stroke, use external guide rails to prevent side-load binding on the seals. This SKU lacks the -S magnet, so CMSE or DMSE position sensors cannot be used. To replace, match the 50 mm bore, 1000 mm stroke, PT1/4 cylinder port, and your mounting choice (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 BSED50X1000 FAQ
The drive force is equal both ways at 825 N at 0.5 MPa and 1154 N at 0.7 MPa, with a maximum drive of 118 kgf. The separate static fail-safe holding force of the spring-applied rod lock is 1400 N.
The spring-applied collet clamps the rod immediately, providing up to 1400 N of static holding force without live air. It is not a dynamic brake, so engage it only after the rod stops. To release, apply pressure to the G1/8 port after balancing both piston sides, allowing at least 0.5 seconds.
