Airtac BSED Clamping Double Acting Cylinder BSED63X50S
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED63X50S 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 BSED63X50S
The AirTAC BSED63X50S is a double-acting, double-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A rod exits both ends, providing equal force and speed in both directions—delivering about 1402 N each way at 0.5 MPa. The rear rod can mount a flag or cam and naturally resists unilateral rotation.
This unit provides a bidirectional fail-safe holding force of 2200 N with no live air required. The collet lock engages when the rod stops and releases via a separate G1/8 port once piston sides are pressure-balanced. It features a 20 mm rod, M16x1.5 thread, PT3/8 cylinder ports, and a 36 mm adjustable cushion at both ends.
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 BSED63X50S 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 BSED63X50S Is Used
Vertical Lift Stations
Secures a 2200 N vertical load mid-stroke during air loss or E-stop, while the dual rods provide 1962 N of stable lifting and lowering force.
Multi-Stop Machining
Holds a workpiece firmly at 50 mm intervals for machining operations, using the rear rod for cam-actuated position signaling.
Pallet Diverter
Drives a lane diverter symmetrically in both directions with 1402 N at 0.5 MPa, locking instantly to prevent drift during transfer.
Is the Airtac BSED Clamping Double Acting Cylinder BSED63X50S the Right Cylinder?
Select this 63 mm bore model when your application requires symmetric drive force and immediate static holding up to 2200 N. At 0.5 MPa, it generates 1402 N of drive force both ways. If your load demands less holding or drive power, the adjacent 50 mm bore provides 825 N of drive force and a 1400 N hold; stepping up to the 80 mm bore yields 2268 N of drive force and a 3600 N hold.
Always engage the lock only after the rod completely stops, and allow at least 0.5 seconds for the release cycle after pressure-balancing both sides. For exact replacements, verify the 50 mm stroke, PT3/8 port, and the -S magnet option for CMSE reed or DMSE electronic sensors.
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 BSED63X50S FAQ
The double-rod drive force is equal both ways: 1402 N at 0.5 MPa and 1962 N at 0.7 MPa (max 200 kgf). The fail-safe rod lock provides a separate bidirectional static holding force of 2200 N.
The spring-applied collet engages automatically upon air loss or E-stop, holding the load up to 2200 N. To release safely, pressure-balance both piston sides, apply air to the G1/8 release port, and allow at least 0.5 seconds before moving.
