About the Airtac BSED Clamping Double Acting Cylinder BSED50X100S
The AirTAC BSED50X100S 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 for symmetric pushing and pulling. It provides a drive force of 825 N each way at 0.5 MPa and 1154 N at 0.7 MPa.
The fail-safe collet lock delivers a 1400 N static holding force without requiring live air, securing the load instantly if pressure drops. The rear rod can mount a cam or flag for position feedback while resisting rotation. A separate G1/8 release port controls the lock, and the included magnetic piston supports CMSE reed and 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 BSED50X100S 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 BSED50X100S Is Used
Vertical Lift Stations
Holds a 1400 N vertical load safely during air loss while providing 1154 N of equal lifting and lowering force for balanced vertical positioning.
Symmetric Press Tooling
Double-rod design allows rear-rod mounting of a cam flag to trigger sensors, while the front rod delivers 825 N of bidirectional clamping pressure at 0.5 MPa.
Mid-Process Pausing
Spring-applied collet locks the conveyor stopper at 100mm stroke during E-stop events, preventing drift without relying on continuous air supply.
Is the Airtac BSED Clamping Double Acting Cylinder BSED50X100S the Right Cylinder?
Select this 50mm bore model when your application requires both symmetric drive force and intermediate fail-safe holding. Verify your load is strictly under the 1400 N static holding limit. If you need less force, the 40mm bore offers 528 N drive force at 0.5 MPa and a 900 N hold. For heavier loads, step up to the 63mm bore, providing 1402 N drive force at 0.5 MPa and a 2200 N hold.
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. This BSED50X100S includes the -S magnet option, uses a PT1/4 cylinder port, and features a 100mm stroke. Maintain proper guide support to prevent side loads.
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 BSED50X100S FAQ
If air is lost or an E-stop trips, the spring-applied collet immediately clamps the rod, providing a 1400 N bidirectional static holding force. The lock is a holding device, not a dynamic brake, so it must only engage after the rod stops moving.
The BSED50X100S delivers an equal drive force of 825 N both ways at 0.5 MPa and 1154 N at 0.7 MPa, with a maximum drive of 118 kgf. The fail-safe rod lock provides a separate 1400 N static holding force with no live air required.
