Airtac BSED Clamping Double Acting Cylinder BSED63X225
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED63X225 combines a double-rod ISO 15552 cylinder — a Ø20mm rod out BOTH ends for equal force both directions — with an integrated spring-applied, air-released ROD LOCK that holds up to 2200 N in either direction if air is lost. Ø63mm bore, 225mm stroke, PT3/8 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED63X225
The AirTAC BSED63X225 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, the annulus area is identical on both sides, yielding equal drive force of 1402 N each way at 0.5 MPa. The rear rod is ideal for mounting a flag or cam and naturally resists rotation.
For fail-safe holding, the internal collet clamps the rod with a 2200 N static holding force, maintaining position without live air if pressure drops or an E-stop trips. This unit has no magnet (-S omitted), so it does not support CMSE or DMSE position sensors. The lock uses a separate G1/8 release port, while the main cylinder ports are PT3/8.
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 BSED63X225 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 BSED63X225 Is Used
Overhead Lift Stations
Holds a 2200 N vertical load safely in place during air loss, while the 1402 N both-way drive raises and lowers the platform with equal speed.
Multi-Station Machining
Uses the rear rod for an external cam while the main rod indexes parts, relying on the fail-safe collet to lock the 225 mm stroke securely between operations.
Pallet Diverters
Diverts heavy pallets with symmetric 1962 N push and pull forces at 0.7 MPa, engaging the lock to freeze the diverter arm when the line halts.
Is the Airtac BSED Clamping Double Acting Cylinder BSED63X225 the Right Cylinder?
Choose this 63 mm bore when an application requires both symmetric thrust and mid-stroke safety holding. Verify your load does not exceed the 2200 N static holding force, and note the drive force is 1962 N each way at 0.7 MPa (max 200 kgf). If you need less force, the 50 mm bore offers 825 N at 0.5 MPa and a 1400 N hold; if you need more, the 80 mm bore provides 2268 N at 0.5 MPa and a 3600 N hold.
Engage the lock only after the rod stops moving, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds for the collet to retract. When replacing a unit, match the 225 mm stroke, PT3/8 port, and mounting choice (Basic, LB, FA, or TC). At 225 mm stroke, guide the load to prevent side-loading and protect the 20 mm rod and 36 mm cushions.
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 BSED63X225 FAQ
The spring-applied collet immediately clamps the rod, providing a 2200 N static holding force to keep the load in place without live air. It is a fail-safe lock, not a dynamic brake, so it must only be engaged after the rod stops.
The 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. Operating pressure is 0.15-0.7 MPa, and speed ranges from 30-800 mm/s.
