Airtac BSED Clamping Double Acting Cylinder BSED63X150S
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED63X150S 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.

About the Airtac BSED Clamping Double Acting Cylinder BSED63X150S
The AirTAC BSED63X150S 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 rear rod provides anti-rotation stability and allows mounting a flag or cam for position feedback.
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. Equipped with a magnetic piston (-S), it supports CMSE reed and DMSE electronic sensors for precise tracking.
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 BSED63X150S 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 BSED63X150S Is Used
Overhead Lift Dwell
Holds a 2200 N vertical lift load securely mid-stroke during E-stops, using the equal 1962 N both-way force to raise and lower the tooling without drift.
Symmetric Machining Clamp
Uses the dual rods to clamp a workpiece from both sides with 1402 N, engaging the fail-safe collet to maintain position if shop air pressure drops.
Pallet Stop Gate
Acts as a bidirectional stop gate where the rear rod mounts an external cam, locking the 2200 N load instantly when the conveyor air supply is cut.
Is the Airtac BSED Clamping Double Acting Cylinder BSED63X150S the Right Cylinder?
Select this 63 mm bore when an application requires symmetric both-way force alongside a 2200 N static hold. If your load demands less force, the 50 mm bore offers 825 N at 0.5 MPa and a 1400 N hold. If you need more capacity, step up to the 80 mm bore, providing 2268 N at 0.5 MPa and a 3600 N hold. Always verify your load is under 2200 N before relying on the lock.
Operating pressure is capped at 0.7 MPa. Engage the lock only when motion stops, and allow at least 0.5 seconds for release once pressure is balanced. For exact replacements, match the 150 mm stroke, PT3/8 cylinder port, M16x1.5 rod thread, and your chosen mounting style (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 BSED63X150S FAQ
If air is lost, the integrated spring-applied collet immediately clamps the rod, providing a 2200 N static holding force to keep the load in place. It is a fail-safe lock, not a dynamic brake, so it only engages after the rod stops moving.
The double-rod design provides equal force both ways: 1402 N at 0.5 MPa and 1962 N at 0.7 MPa, with a maximum drive of 200 kgf. The static holding force of the rod lock is 2200 N.
