About the Airtac BSED Clamping Double Acting Cylinder BSED63X250
The AirTAC BSED63X250 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. The collet lock provides a 2200 N static holding force with no live air required, ensuring immediate fail-safe positioning if air pressure drops.
This 63 mm bore unit uses a PT3/8 cylinder port and a separate G1/8 lock-release port. Unlike a dynamic brake, this collet engages only after the rod stops and releases when piston sides are pressure-balanced. The extruded aluminum barrel has no external tie rods, and this specific SKU lacks a magnet, meaning no CMSE or DMSE position sensors can be attached.
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 BSED63X250 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 BSED63X250 Is Used
Vertical Lift Jigs
Holds a 2200 N vertical jig in place instantly during an air loss event, while the 1402 N both-way drive smoothly raises and lowers the mass.
Pallet Stopper Arms
Uses the twin rods to mount a stopper blade on one end and a cam flag on the rear, resisting rotation while locking 1962 N of drive force.
Machining Clamps
Secures machined parts during cutting cycles; the fail-safe collet maintains the clamp without live air, preventing movement under vibration.
Is the Airtac BSED Clamping Double Acting Cylinder BSED63X250 the Right Cylinder?
Select this 250 mm stroke model when your application requires symmetric both-way force and a 2200 N fail-safe hold. If your load demands less force, the adjacent 50 mm bore provides 825 N at 0.5 MPa and 1400 N holding force. For heavier loads, step up to the 80 mm bore, which yields 2268 N at 0.5 MPa and 3600 N holding force. Always verify your load is within the 2200 N static limit.
Engage the lock only after the rod completely stops, and allow at least 0.5 seconds for release once both sides are pressure-balanced. Operating pressure is capped at 0.7 MPa. For this 250 mm stroke, ensure external guides support side loads to prevent binding. To match this SKU exactly when ordering replacements, confirm the 63 mm bore, 250 mm stroke, PT3/8 thread, Basic/LB/FA/TC mounting, and the absence of a 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 BSED63X250 FAQ
The spring-applied collet instantly clamps the rod, providing a 2200 N static holding force with no live air. It is a fail-safe lock, not a dynamic brake, so it only engages after the rod stops. For overhead or man-rated loads, use separate safety-rated controls.
The equal both-way drive force is 1402 N at 0.5 MPa and 1962 N at 0.7 MPa, with a maximum drive of 200 kgf. To release the 2200 N lock, apply pressure to the G1/8 release port only after both piston sides are pressure-balanced, allowing at least 0.5 seconds.
