Airtac BSED Clamping Double Acting Cylinder BSED63X450S
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED63X450S 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, 450mm stroke, PT3/8 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED63X450S
The AirTAC BSED63X450S 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—about 1402 N each way at 0.5 MPa. The rear rod is ideal for mounting external flags or resisting rotation.
This fail-safe collet lock provides a 2200 N static holding force with no live air required. It engages only after the rod stops and releases via a dedicated G1/8 port when piston sides are pressure-balanced. Operating pressure is capped at 0.7 MPa, and the included -S magnet supports CMSE reed and DMSE electronic 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 BSED63X450S 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 BSED63X450S Is Used
Z-Axis Servo Elevators
Holds a vertical machining head mid-travel with 2200 N of fail-safe force, while the 1962 N both-way drive ensures rapid and equal up/down positioning.
Dual-Tool Indexing Carriage
Uses the double-rod design to mount a secondary tool or cam on the rear rod, locking the 450 mm stroke securely during tool changes.
Pallet Diverters
Provides equal push and pull force to index pallets, engaging the collet lock to hold the diverter blade rigidly against shock loads.
Is the Airtac BSED Clamping Double Acting Cylinder BSED63X450S the Right Cylinder?
Select this 63 mm bore when your application requires both-way symmetric drive (1962 N at 0.7 MPa) and intermediate stopping. Verify your load requires holding at or below 2200 N. If you need less force, the 50 mm bore offers 825 N at 0.5 MPa and 1400 N holding; for heavier loads, step up to the 80 mm bore providing 2268 N at 0.5 MPa and 3600 N holding.
Always engage the lock only after the rod stops, and allow at least 0.5 seconds for release once pressure is balanced. Because the stroke is 450 mm, ensure adequate external guide support to prevent excessive side-loading on the rod. Replacement matches require the 63 mm bore, 450 mm stroke, PT3/8 port, and -S magnet.
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 BSED63X450S FAQ
The integrated rod lock is spring-applied, so it automatically clamps the rod and holds the load with a 2200 N static force. It is a fail-safe holding device, not a dynamic brake, and requires no live air to maintain position.
The drive force is equal both ways: 1402 N at 0.5 MPa and 1962 N at 0.7 MPa (max 200 kgf). The static holding force of the lock is 2200 N. Operating speed ranges from 30-800 mm/s, with operating pressure capped at 0.7 MPa.
