Airtac BSED Clamping Double Acting Cylinder BSED63X700
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED63X700 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, 700mm stroke, PT3/8 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED63X700
The AirTAC BSED63X700 is a double-acting, double-rod ISO 15552 profile cylinder with 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 1962 N at 0.7 MPa. The extruded aluminum barrel contains no external tie rods, ensuring a clean ISO 15552 mounting interface.
The fail-safe collet lock provides a 2200 N static holding force in both directions without requiring live air. It uses a separate G1/8 release port, and the cylinder port is PT3/8. This unit has no position magnet, so it operates without CMSE or DMSE 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 BSED63X700 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 BSED63X700 Is Used
Servo Welding Axlse
Uses the equal 1962 N both-way force to position a weld head, while the 2200 N lock holds the head precisely in place during the weld cycle to prevent deflection.
Overhead Lift Stations
The rear rod supports a cam for external tracking, and the spring-applied collet clamps the load safely if air pressure drops below the 0.15 MPa threshold.
Pallet Transfer Stops
A rod extends through both ends to mount dual stop flags, using the 1402 N drive at 0.5 MPa to index and the fail-safe lock to hold heavy pallets.
Is the Airtac BSED Clamping Double Acting Cylinder BSED63X700 the Right Cylinder?
Select this 63 mm bore model when your application needs symmetric push and pull forces alongside a 2200 N fail-safe hold. If your load exceeds 2200 N, step up to the 80 mm bore, which offers 3175 N drive force at 0.7 MPa and a 3600 N hold. If you need less force, the 50 mm bore provides 1154 N drive and a 1400 N hold. Always verify your actual load is under the 2200 N limit.
Because the 700 mm stroke is long, use a guide to prevent side loads from damaging the seals. The lock is a static holding device, not a dynamic brake; engage it only after the rod stops moving. Release the lock only when both piston sides are pressure-balanced, allowing at least 0.5 seconds for the transition.
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 BSED63X700 FAQ
The spring-applied collet clamps the rod immediately, providing a 2200 N static holding force in both directions without any live air. It is a static lock, not a dynamic brake, so it must only be engaged after the rod stops moving.
The BSED63X700 delivers equal drive force of 1402 N at 0.5 MPa and 1962 N at 0.7 MPa (max 200 kgf) both ways. The static holding force of the lock is 2200 N. Operating speed is 30-800 mm/s, operating pressure is 0.15-0.7 MPa, and the lock-release port is G1/8.
