Airtac BSED Clamping Double Acting Cylinder BSED80X150S
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED80X150S combines a double-rod ISO 15552 cylinder — a Ø25mm rod out BOTH ends for equal force both directions — with an integrated spring-applied, air-released ROD LOCK that holds up to 3600 N in either direction if air is lost. Ø80mm bore, 150mm stroke, PT3/8 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED80X150S
The AirTAC BSED80X150S is a double-acting, double-rod ISO 15552 cylinder featuring an integrated spring-applied, air-released rod lock. A rod exits both ends to deliver equal force in both directions, generating 2268 N each way at 0.5 MPa and 3175 N at 0.7 MPa. The rear rod provides stable mounting for tooling or position flags while resisting rotation. The collet lock delivers a 3600 N static holding force, clamping the rod securely during pressure loss or E-stop events.
This profile-type extruded-aluminum cylinder uses a separate G1/8 port for lock release, keeping the fail-safe mechanism entirely distinct from the adjustable air cushions at both ends. Operating pressure is capped at 0.7 MPa, and the integrated -S magnet enables position detection with CMSE reed or DMSE electronic sensors. The lock is a static holding device, not a dynamic brake, engaging only after the rod stops.
Double Rod + 3600 N Rod Lock (Ø80mm)
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 BSED80X150S 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 (Ø80mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 2268 N |
| 0.7 MPa (max) | 3175 N |
| Max drive (@0.7 MPa) | 324 kgf |
A rod exits both ends, so force is equal on extend and retract. Drive force is separate from the 3600 N static lock holding force. Size with a safety margin.

Where the Airtac BSED Clamping Double Acting Cylinder BSED80X150S Is Used
Mid-Stroke Machining Jig
Holds a 3600 N machining fixture firmly on both strokes while the double-rod delivers 3175 N of equal clamping force for balanced material processing.
Overhead Lift Stop
Secures a vertical lift load instantly upon air loss using the 3600 N collet, while the dual rods prevent platform twisting during transit.
Reciprocating Shuttle
Provides 2268 N of equal push/pull force at 0.5 MPa for a reversing conveyor shuttle, locking the 80 mm rod safely during changeovers.
Is the Airtac BSED Clamping Double Acting Cylinder BSED80X150S the Right Cylinder?
Select this 80 mm bore model when your application demands symmetric both-way force and failsafe mid-stroke holding. Verify your load requires holding at or below 3600 N. If you need less drive force, the 63 mm bore offers 1402 N at 0.5 MPa and a 2200 N hold; if you need more power, the 100 mm bore provides 3681 N at 0.5 MPa and a 5500 N hold. Engage the lock only after the rod stops, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds for the transition. Replacement matches require bore 80 mm, 150 mm stroke, PT3/8 cylinder porting, and the -S magnet. For any stroke of 300 mm or longer, add external guide rails to prevent side-load wear.
Quick checklist
- ✓ Need both symmetric force AND fail-safe hold?
- ✓ Load to hold ≤ 3600 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 BSED80X150S FAQ
The spring-applied collet immediately clamps the rod, delivering a 3600 N static holding force to prevent movement. It is a fail-safe static lock, not a dynamic brake, so it must only be engaged after the rod stops. To release the lock safely, both piston sides must be pressure-balanced, allowing at least 0.5 seconds for the transition.
The double-rod design delivers equal force both ways: 2268 N at 0.5 MPa and 3175 N at 0.7 MPa, with a maximum drive force of 324 kgf. The fail-safe rod lock provides a separate 3600 N static holding force with no live air required. Operating pressure is capped at 0.7 MPa.
