About the Airtac BSED Clamping Double Acting Cylinder BSED63X800S
The AirTAC BSED63X800S is a double-acting, double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A rod exits both ends, providing equal drive force of 1402 N each way at 0.5 MPa and a maximum of 1962 N at 0.7 MPa. The collet lock delivers a bidirectional static holding force of 2200 N without requiring live air.
This 63 mm bore unit operates at 30-800 mm/s with a PT3/8 cylinder port and a dedicated G1/8 lock-release port. The integrated magnet (-S) supports CMSE reed and DMSE electronic sensors. Engage the lock only after the rod stops, and release it when both piston sides are pressure-balanced, allowing at least 0.5 seconds.
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 BSED63X800S 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 BSED63X800S Is Used
Vertical Lift Rigging
Raises and lowers 1402 N loads at 0.5 MPa with equal both-way force, while the 2200 N fail-safe collet secures the 800 mm stroke position instantly if air pressure drops.
Symmetric Machining Jig
Clamps parts from both ends using the dual rods; the spring-applied lock holds the 1962 N drive force steady during cycle interruptions, preventing drift.
Long-Travel Pallet Stop
Uses the 800 mm stroke to index heavy pallets; the rear rod carries a flag for DMSE sensors while the 2200 N lock halts the load safely during E-stops.
Is the Airtac BSED Clamping Double Acting Cylinder BSED63X800S the Right Cylinder?
Select this model when an application requires symmetric both-way force and a 2200 N fail-safe hold. If your load demands less holding or drive force, the 50 mm bore offers 825 N at 0.5 MPa and a 1400 N static hold. If you need more capacity, step up to the 80 mm bore, which provides 2268 N at 0.5 MPa and a 3600 N hold. Always verify your load is under 2200 N.
With an 800 mm stroke, use a linear guide to manage side loads and prevent rod binding. The lock is a static holding device, not a dynamic brake; engage it only after motion stops. For overhead or man-rated loads, use safety-rated controls. Replacement units must match the 63 mm bore, 800 mm stroke, PT3/8 thread, 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 BSED63X800S FAQ
The spring-applied collet engages automatically, providing a bidirectional static holding force of 2200 N to keep the rod at position. It is a fail-safe hold, not a dynamic brake, so it must engage only after the rod stops moving.
The drive force is equal both ways: 1402 N at 0.5 MPa and 1962 N at 0.7 MPa, equating to a max drive of 200 kgf. The fail-safe rod lock provides a separate 2200 N static holding force. Release the lock only when both piston sides are pressure-balanced.
