Airtac BSED Clamping Double Acting Cylinder BSED63X500S
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED63X500S 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, 500mm stroke, PT3/8 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED63X500S
The AirTAC BSED63X500S 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 and 1962 N at 0.7 MPa. The 500 mm stroke is standard, and the -S suffix indicates a built-in magnet for position sensing.
The fail-safe collet lock provides a bidirectional static holding force of 2200 N with no live air required. If pressure drops or an E-stop trips, the rod is clamped securely at its position. The lock engages via a dedicated G1/8 release port and is a static holding device, not a dynamic brake. Operating pressure is capped at 0.7 MPa, and the extruded aluminum barrel has no external tie rods.
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 BSED63X500S 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 BSED63X500S Is Used
Vertical Lift Gates
Holds a 2200 N vertical load securely in place during air loss, while the 1962 N equal both-way drive force ensures smooth, symmetric lifting and lowering of heavy gates.
Mid-Stroke Machining Clamps
Provides rigid bidirectional workholding for a machining head. The double-rod design resists rotation, and the lock maintains position without needing continuous air supply.
Pallet Diverters
Drives a diverter arm with equal speed and force in both directions. The fail-safe lock stops the arm instantly if the air supply drops, protecting the conveyor line.
Is the Airtac BSED Clamping Double Acting Cylinder BSED63X500S the Right Cylinder?
Select this 63 mm bore model when your application demands symmetric both-way drive force and mid-stroke fail-safe holding up to 2200 N. If your load requires less force, the 50 mm bore offers 825 N at 0.5 MPa and a 1400 N hold; for heavier loads, the 80 mm bore provides 2268 N at 0.5 MPa and a 3600 N hold. Always verify your load stays under the 2200 N static limit.
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 the transition. At 500 mm stroke, use a guide to prevent side loads from damaging the seals. This replacement requires matching the 63 mm bore, 500 mm stroke, PT3/8 cylinder port, and -S magnet option.
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 BSED63X500S FAQ
The drive force is equal both ways: 1402 N at 0.5 MPa and 1962 N at 0.7 MPa (max 200 kgf). The integrated rod lock provides a separate bidirectional static holding force of 2200 N with no live air.
The spring-applied collet clamps the rod automatically when air is lost or an E-stop trips, holding up to 2200 N. It is a static lock, not a dynamic brake—engage it only after the rod stops, and release it only when both piston sides are pressure-balanced via the G1/8 port, allowing at least 0.5 seconds.
