Airtac BSED Clamping Double Acting Cylinder BSED63X300
The AirTAC BSED Clamping Double Acting Cylinder BSED63X300 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, 300mm stroke, PT3/8 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED63X300
The AirTAC BSED63X300 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 drive force of 1402 N each way at 0.5 MPa and 1962 N at 0.7 MPa. The extruded aluminum barrel has no external tie rods, and the rear rod is ideal for mounting tooling or flags while resisting rotation.
The fail-safe collet lock provides a 2200 N static holding force with no live air required. It engages bidirectionally to secure the 300 mm stroke position if air pressure drops. A separate G1/8 release port controls the lock, and the cylinder port is PT3/8. This non-magnet SKU lacks position sensors, relying purely on mechanical clamping for secure stops.
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 BSED63X300 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 BSED63X300 Is Used
Vertical Lift Stations
Provides 1962 N of equal both-way drive for vertical lifting and secures the load with 2200 N of static holding force during E-stops or air loss.
Pallet Transfer Stops
Uses the double-rod for equal push and pull on conveyor indexing, while the fail-safe collet locks the 300 mm stroke mid-travel to halt pallets securely.
Multi-Position Machining
The rear rod resists rotation for accurate tooling placement, and the spring-applied lock holds the workpiece with zero live air during machining pauses.
Is the Airtac BSED Clamping Double Acting Cylinder BSED63X300 the Right Cylinder?
Choose this 63 mm bore when your application requires symmetric both-way force and a robust 2200 N static hold. If your load exceeds 2200 N or you need higher drive force, step up to the 80 mm bore (3175 N drive at 0.7 MPa, 3600 N holding force). If you need less force, step down to the 50 mm bore (1154 N drive at 0.7 MPa, 1400 N holding force). Always ensure the load is stopped before engaging the lock and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds.
Because the 300 mm stroke is relatively long, use a guide to prevent side loads from damaging the rod and seals. The lock is a static holding device, not a dynamic brake. For overhead or man-rated loads, always use safety-rated controls. Replacement parts must match the 63 mm bore, 300 mm stroke, PT3/8 port, and Basic, LB, FA, or TC mounting.
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 BSED63X300 FAQ
The integrated spring-applied collet engages automatically, providing a 2200 N static holding force to secure the rod in place. It is a fail-safe lock, not a dynamic brake, so it only engages after the rod has stopped moving.
The double-rod design delivers equal force both directions: 1402 N at 0.5 MPa and 1962 N at 0.7 MPa, with a maximum drive of 200 kgf. To release the 2200 N lock safely, apply air to the G1/8 release port only after both piston sides are pressure-balanced, allowing at least 0.5 seconds for the collet to disengage.
