Airtac BSED Clamping Double Acting Cylinder BSED63X350
The AirTAC BSED Clamping Double Acting Cylinder BSED63X350 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, 350mm stroke, PT3/8 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED63X350
The AirTAC BSED63X350 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 thrust in both directions—about 1402 N each way at 0.5 MPa. The rear rod is ideal for mounting a flag or cam and naturally resists rotation.
The fail-safe collet lock provides a 2200 N static holding force without requiring live air, clamping the Ø20 mm rod bidirectionally if pressure drops. Operating pressure is capped at 0.7 MPa, and the lock releases via a separate G1/8 port. This SKU has no magnet, so position sensing is not available.
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 BSED63X350 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.

Specifications follow the official AirTAC BSED datasheet. Rod thread M16×1.5 both ends. Mounting (BSED): Basic, LB, FA, TC. Port options: PT (standard) / G (BSPP); lock-release port is G1/8.
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 BSED63X350 Is Used
Machining Fixture Clamping
Holds a workpiece fixture with 1962 N of both-way force, engaging the 2200 N rod lock to prevent drift during cutting operations.
Pallet Diverting Gate
Uses the double-rod for equal push and pull speed on a diverting arm, locking securely mid-stroke to halt a 2200 N load.
Indexing Lift Platform
Raises and lowers a platform with symmetric force, relying on the fail-safe collet to hold the 350 mm stroke position securely.
Is the Airtac BSED Clamping Double Acting Cylinder BSED63X350 the Right Cylinder?
Select this 63 mm bore when an application needs symmetric 1962 N drive force at 0.7 MPa alongside a 2200 N fail-safe hold. If your load requires less force, the 50 mm bore offers 1154 N and 1400 N holding; if you need more, step up to the 80 mm bore providing 3175 N drive and 3600 N holding. Always confirm your load is under 2200 N before relying on the lock.
Engage the lock only after the rod completely stops, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds. For this 350 mm stroke, use a guide rail to prevent side-load damage to the extruded aluminum barrel. Replacement requires matching the 63 mm bore, 350 mm stroke, PT3/8 port, and mounting choice (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 BSED63X350 FAQ
The spring-applied collet clamps the rod instantly, providing a 2200 N static holding force without live air. It is a fail-safe hold, not a dynamic brake, so engage it only after the rod stops.
The drive force is equal both ways: 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, with a max drive of 200 kgf. The separate static holding force of the lock is 2200 N.
