Airtac BSED Clamping Double Acting Cylinder BSED63X50
The AirTAC BSED Clamping Double Acting Cylinder BSED63X50 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, 50mm stroke, PT3/8 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED63X50
The AirTAC BSED63X50 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, it delivers equal drive force in both directions—1402 N each way at 0.5 MPa and 1962 N at 0.7 MPa. The rear rod is ideal for mounting flags or cams and naturally resists rotation.
A separate G1/8 release port controls the collet mechanism, which provides a 2200 N static holding force without consuming live air. If air pressure drops or an E-stop trips, the lock engages automatically to hold the load in place. This unit has no magnet (-S omitted), so it does not support CMSE or DMSE position 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 BSED63X50 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 BSED63X50 Is Used
Overhead Lift Stations
Holds a 2200 N vertical load safely in place during air loss, while the 1962 N both-way drive raises and lowers the platform with balanced speed.
Multi-Tool Machining
Uses the rear exiting rod to mount a cam for sequence timing, providing 1402 N of equal thrust at 0.5 MPa to actuate a machining gate.
Pallet Diverters
Clamps the diverter arm mid-stroke to prevent drift from heavy side loads, engaging the collet only after the 63 mm bore stops moving.
Is the Airtac BSED Clamping Double Acting Cylinder BSED63X50 the Right Cylinder?
Select this 63 mm bore when an application demands symmetric thrust and fail-safe holding. Verify your load requires no more than 2200 N of static holding force and 1962 N of drive thrust at 0.7 MPa. If you need less force, the 50 mm bore provides 825 N at 0.5 MPa and 1154 N of holding force; if you need more, stepping up to the 80 mm bore yields 2268 N at 0.5 MPa and 3600 N of holding force.
Always 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 s for the transition. When replacing a unit, match the 50 mm stroke, PT3/8 cylinder port, and your chosen mounting style (Basic, LB, FA, or TC).
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 BSED63X50 FAQ
The integrated spring-applied collet engages automatically, providing a 2200 N static holding force to keep the rod at position. 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 at 1402 N at 0.5 MPa and 1962 N at 0.7 MPa, with a maximum drive of 200 kgf. The static fail-safe holding force of the rod lock is 2200 N.
