Airtac BSED Clamping Double Acting Cylinder BSED63X500
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED63X500 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 BSED63X500
The AirTAC BSED63X500 is a double-acting, double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A rod exits both ends, providing equal drive force of 1402 N each way at 0.5 MPa and 1962 N at 0.7 MPa. The bidirectional collet lock delivers a 2200 N static holding force to secure the load with no live air required.
This 63 mm bore unit has a 500 mm stroke, a PT3/8 cylinder port, and a separate G1/8 lock-release port. The extruded aluminum barrel has no external tie rods, and the rear rod can mount a flag or tooling while resisting rotation. This SKU has no magnet, so it does not support position 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 BSED63X500 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 BSED63X500 Is Used
Vertical Lift Jigs
Holds a 2200 N vertical workpiece securely mid-stroke during air loss, while the 1962 N both-way force drives the lift cycle.
Multi-Stop Machining
Provides anti-rotation for rear-rod tooling and locks the 500 mm stroke instantly when the E-stop is tripped.
Pallet Indexing
Shifts heavy pallets with equal push and pull force, engaging the collet lock to hold the assembly during station pauses.
Is the Airtac BSED Clamping Double Acting Cylinder BSED63X500 the Right Cylinder?
Select this model when an application demands symmetric both-way force and fail-safe holding up to 2200 N. If your load exceeds 2200 N, step up to the 80 mm bore (3175 N drive, 3600 N hold); if you need less force, step down to the 50 mm bore (1154 N drive, 1400 N hold). The lock is a static holding device, not a dynamic brake—engage it only after the rod stops, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds. For a 500 mm stroke, use external guides to prevent side-load wear on the seals. To replace this unit, match the 63 mm bore, 500 mm stroke, PT3/8 port, and your 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 BSED63X500 FAQ
The spring-applied collet engages automatically, providing a 2200 N static holding force to keep the rod at position. It is a fail-safe lock, not a dynamic brake, so it only engages after the rod stops. For overhead or man-rated loads, use safety-rated controls.
The drive force is equal both ways: 1402 N at 0.5 MPa and 1962 N at 0.7 MPa (max 200 kgf). To release the 2200 N lock, apply pressure to the G1/8 release port only after both cylinder sides are pressure-balanced, allowing at least 0.5 seconds for the collet to disengage.
