About the Airtac BSED Clamping Double Acting Cylinder BSED63X225S
The AirTAC BSED63X225S 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 drive force of 1402 N each way at 0.5 MPa and a maximum of 1962 N at 0.7 MPa. The rear rod is ideal for mounting tooling, flags, or cams while resisting rotational torque.
This fail-safe collet lock provides a 2200 N bidirectional static holding force with zero live air required. It activates instantly upon air loss or E-stop to secure your load. The lock uses a dedicated G1/8 release port, and the -S option includes a magnet for CMSE reed and DMSE electronic sensors.
Double Rod + 2200 N Rod Lock (Ø63mm)
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 BSED63X225S 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 (Ø63mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 1402 N |
| 0.7 MPa (max) | 1962 N |
| Max drive (@0.7 MPa) | 200 kgf |
A rod exits both ends, so force is equal on extend and retract. Drive force is separate from the 2200 N static lock holding force. Size with a safety margin.

Where the Airtac BSED Clamping Double Acting Cylinder BSED63X225S Is Used
Machining Clamps
Secures workpieces using 1962 N of equal both-way force, while the 2200 N spring-applied lock holds the clamp firmly during an air pressure drop.
Vertical Lift Stations
Lifts and lowers jigs with symmetric push and pull. The fail-safe collet engages instantly on E-stop to prevent gravity-driven drops up to 2200 N.
Transfer Shuttltes
Uses the rear exiting rod for cam tracking while transferring 200 kgf loads, locking securely at the end of travel without needing continuous air.
Is the Airtac BSED Clamping Double Acting Cylinder BSED63X225S the Right Cylinder?
Select this 63 mm bore when your application demands symmetric both-way force and a 2200 N fail-safe hold. If your load requires less force, the 50 mm bore offers 825 N at 0.5 MPa and a 1400 N hold. If you need heavier securing, step up to the 80 mm bore, providing 2268 N at 0.5 MPa and a 3600 N hold. Always verify your static load is at or below 2200 N.
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. Since the 225 mm stroke provides extended reach, use guide rails to prevent side-load wear on the ISO 15552 extruded aluminum barrel. Direct replacements must match the 63 mm bore, 225 mm stroke, PT3/8 cylinder port, and -S magnet.
Quick checklist
- ✓ Need both symmetric force AND fail-safe hold?
- ✓ Load to hold ≤ 2200 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 BSED63X225S FAQ
The integrated spring-applied collet immediately clamps the rod, providing a 2200 N bidirectional static hold with no live air. It is a fail-safe holding device, not a dynamic brake, so it must only engage after the rod stops.
The double-rod drive force is equal both ways: 1402 N at 0.5 MPa and 1962 N at 0.7 MPa (max 200 kgf). The static holding force of the lock is 2200 N. Release the lock via the G1/8 port only when both sides are pressure-balanced, allowing at least 0.5 s.
