Airtac BSED Clamping Double Acting Cylinder BSED63X400
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED63X400 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, 400mm stroke, PT3/8 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED63X400
The AirTAC BSED63X400 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 force in both directions—1402 N each way at 0.5 MPa. The fail-safe collet mechanism provides a 2200 N static holding force to secure the load without consuming live air.
This 63 mm bore, 400 mm stroke unit uses a PT3/8 cylinder port and a separate G1/8 lock-release port. Because this SKU lacks the -S magnet option, it does not support CMSE or DMSE position sensors. The extruded aluminum profile body incorporates adjustable air cushions at both ends, while the rod lock engages only after the piston stops, requiring >=0.5 s to release once pressure is balanced.
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 BSED63X400 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 BSED63X400 Is Used
Overhead Lift Stations
Holds a 2200 N vertical load in place during an E-stop or pressure loss, while the 1962 N both-way drive raises and lowers the carriage.
Dual-Tool Machining
Uses the rear rod for a flag or cam while the front rod drives a 1402 N tooling head, ensuring symmetric push and pull forces.
Pallet Stops
Secures a 400 mm stroke pallet stop in position with the fail-safe collet, preventing drift when the 0.7 MPa air supply is removed.
Is the Airtac BSED Clamping Double Acting Cylinder BSED63X400 the Right Cylinder?
Select this 63 mm bore model when an application requires both-way symmetric thrust (1962 N at 0.7 MPa) and 2200 N of static drop-prevention. If your load is lighter, the 50 mm bore offers 825 N drive force at 0.5 MPa and 1400 N holding force. If you need heavier lifting, step up to the 80 mm bore, which provides 2268 N drive force at 0.5 MPa and 3600 N holding force. Always verify your load is under 2200 N to prevent slipping.
At 400 mm of stroke, the extended rod is susceptible to bending under side loads; use external linear guides to prevent premature seal wear. To replace this unit, match the 63 mm bore, 400 mm stroke, PT3/8 port thread, and your mounting choice (Basic, LB, FA, or TC). Remember the lock is not a dynamic brake: engage it only after the rod stops, and release it only when both piston sides are pressure-balanced.
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 BSED63X400 FAQ
The integrated spring-applied collet immediately clamps the rod, providing a 2200 N static holding force to keep the load in place. It is a fail-safe lock, not a dynamic brake, so it must only be engaged after the rod has stopped moving.
The drive force is equal both ways: 1402 N at 0.5 MPa and 1962 N at 0.7 MPa (max 200 kgf). The separate static holding force of the rod lock is 2200 N. Operating pressure is capped at 0.7 MPa.
