The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED80X600 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, 600mm stroke, PT3/8 ports, G1/8 lock-release.
The AirTAC BSED80X600 is a double-acting, double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A rod exits both ends, yielding equal force in both directions—2268 N each way at 0.5 MPa. The rear rod is ideal for mounting flags or anti-rotation tooling.
This unit delivers a 3600 N static fail-safe holding force via a bidirectional collet that clamps the rod with no live air. It uses a PT3/8 cylinder port and a separate G1/8 release port. Note this SKU lacks a magnet, so CMSE or DMSE position sensors cannot be used.
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 BSED80X600 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.

| 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.

Thread: PT (blank) / G. Mounting (BSED): Basic, LB, FA, TC. Related: SED (double rod, no lock), BSE (single-rod rod lock). Sensors CMSE/DMSE fit magnetic BSED.
Holds a 300 kg elevated gate securely in place during an air loss event using the 3600 N fail-safe collet, while the 3175 N both-way drive raises and lowers it smoothly.
Uses the rear exiting rod for mounting a return-side cam, leveraging the equal 2268 N force at 0.5 MPa to actuate a secondary clamping mechanism.
Locks the extended 25 mm rod instantly upon E-stop to halt a pallet assembly line, relying on the spring-applied lock rather than live air pressure.
Select this 80 mm bore when an application requires 3175 N of equal both-way drive force at 0.7 MPa and a 3600 N static hold. If your load needs less force, the 63 mm bore provides 1402 N drive and 2200 N holding force. For heavier loads, the 100 mm bore offers 3681 N drive and 5500 N holding force. Always verify your load is under 3600 N.
Engage the lock only after the rod stops, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 s. Because the 600 mm stroke increases side-load risks, use external guide rails to prevent rod binding. Replacement matches require an 80 mm bore, 600 mm stroke, PT3/8 port, and your chosen mounting (Basic, LB, FA, or TC).
Quick checklist
The integrated spring-applied collet engages automatically, providing a 3600 N static holding force to keep the rod in position. It is a fail-safe lock, not a dynamic brake, so it must only engage after the rod has stopped moving.
The drive force is equal both ways: 2268 N at 0.5 MPa and 3175 N at 0.7 MPa (max 324 kgf). The static fail-safe holding force of the rod lock is 3600 N. Release the lock via the G1/8 port only when both piston sides are pressure-balanced.
