Airtac BSED Clamping Double Acting Cylinder BSED80X300S
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED80X300S 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, 300mm stroke, PT3/8 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED80X300S
The AirTAC BSED80X300S 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 2268 N each way at 0.5 MPa (3175 N at 0.7 MPa). The collet lock provides a 3600 N static holding force, securing the load safely with no live air required.
This 80mm bore unit includes a magnetic piston (-S) for CMSE or DMSE sensors and a separate G1/8 release port. The bidirectional lock engages only after the rod stops and releases when piston sides are pressure-balanced. It uses a PT3/8 cylinder port, an M20x1.5 rod thread, and adjustable air cushions at both ends.
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 BSED80X300S 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 BSED80X300S Is Used
Overhead Z-Axis Safety
Secures vertical lifting stages with a 3600 N static hold during air loss, while the double-rod provides 3175 N of equal lifting and lowering force.
Symmetric Machining Jig
Clamps workpieces from both ends using the dual rods, ensuring equal 2268 N force at 0.5 MPa and holding position firmly during cycle interruptions.
Pallet Stop & Hold
Halts and locks heavy conveyor pallets with a 3600 N fail-safe grip, utilizing the rear rod for cam flag tracking without affecting front tooling.
Is the Airtac BSED Clamping Double Acting Cylinder BSED80X300S the Right Cylinder?
Select this 80mm bore model when you need both symmetric both-way force (3175 N at 0.7 MPa) and a 3600 N fail-safe hold. If your load requires less force, the 63mm bore delivers 1402 N at 0.5 MPa with a 2200 N hold. For heavier demands, the 100mm bore provides 3681 N at 0.5 MPa and a 5500 N hold. Verify your load stays under 3600 N when locked.
At 300mm stroke, use a guide to prevent side-load damage. To release the lock safely, ensure both piston sides are pressure-balanced and allow at least 0.5 seconds before moving. For exact replacements, match the 80mm bore, 300mm stroke, PT3/8 port, and magnet option.
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 BSED80X300S FAQ
The spring-applied collet immediately engages, providing a 3600 N bidirectional static holding force to keep the rod at position. The lock is a fail-safe hold, not a dynamic brake, and must only engage after the rod stops.
The double-rod drive force is equal both ways: 2268 N at 0.5 MPa and 3175 N at 0.7 MPa (max 324 kgf). The integrated fail-safe rod lock provides a separate 3600 N static holding force.
