About the Airtac BSED Clamping Double Acting Cylinder BSED50X600
The AirTAC BSED50X600 is a double-acting, double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. Because a rod exits both ends, it provides equal drive force in both directions—delivering 825 N each way at 0.5 MPa and 1154 N at 0.7 MPa. The symmetrical annulus area ensures consistent speeds and allows rear-rod tooling or cam mounting while resisting rotation.
A separate G1/8 release port controls the fail-safe collet, which provides a 1400 N static holding force with zero live air. If air pressure drops or an E-stop trips, the lock clamps the Ø20 mm rod instantly to hold the load in place. This unit 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 BSED50X600 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.

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 BSED50X600 Is Used
Vertical Lift Gates
Raises and lowers heavy access gates using 1154 N of equal both-way force, engaging the 1400 N fail-safe collet to prevent gravity drops during an air loss event.
Symmetric Transfer Arms
Drives long transfer arms back and forth at consistent speeds, utilizing the double-rod design for rear-mounted flags while locking securely mid-cycle for part inspection.
Z-Axis Tooling Slides
Positions machining heads with equal extension and retraction thrust, relying on the spring-applied lock to hold the 600 mm stroke rigidly during workpiece changes.
Is the Airtac BSED Clamping Double Acting Cylinder BSED50X600 the Right Cylinder?
Choose this 50 mm bore when an application requires symmetric thrust up to 1154 N alongside a 1400 N fail-safe hold. If your load requires less force, the 40 mm bore offers 528 N at 0.5 MPa and a 900 N holding force. If you need more power, stepping up to the 63 mm bore yields 1402 N at 0.5 MPa and a 2200 N holding capacity. Always verify your load stays under the 1400 N static limit.
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. Because the 600 mm stroke is long, ensure external guide rails are used to prevent excessive side-loading on the rod. When replacing, match the 50 mm bore, 600 mm stroke, PT1/4 cylinder port, and mounting style (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 BSED50X600 FAQ
The double-rod design provides equal drive force in both directions: 825 N at 0.5 MPa and 1154 N at 0.7 MPa (max 118 kgf). The integrated fail-safe rod lock provides a separate 1400 N static holding force with no live air required.
The collet is spring-applied, so if air pressure is lost or an E-stop is engaged, the lock immediately clamps the rod with 1400 N of holding force. To release it safely, ensure both piston sides are pressure-balanced and apply air to the G1/8 release port for at least 0.5 seconds.
