The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED80X175S 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, 175mm stroke, PT3/8 ports, G1/8 lock-release.
The AirTAC BSED80X175S 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 force and speed in both directions—delivering 2268 N each way at 0.5 MPa and 3175 N at 0.7 MPa. The rear rod is ideal for mounting flags, cams, or tooling while resisting rotation.
This fail-safe collet lock provides a bidirectional static holding force of 3600 N without requiring live air. If air pressure drops or an E-stop trips, the rod is securely clamped at position. It engages only after the rod stops and releases via a dedicated G1/8 port once piston sides are pressure-balanced. The -S magnet enables position sensing with CMSE reed or DMSE electronic switches.
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 BSED80X175S 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 elevated gates securely in place with 3600 N of static force during air loss, while the double-rod design drives 3175 N consistently in both up and down directions.
Provides hard stopping for heavy pallets using equal both-way force, with the fail-safe collet preventing any drift when the conveyor line is depressurized for maintenance.
Mounts a work clamp on the front rod and a sensor flag on the rear rod, utilizing anti-rotation properties and 2268 N of symmetric force for precise machining cycles.
Select this 80 mm bore when an application requires both-way symmetric drive (324 kgf max at 0.7 MPa) combined with fail-safe holding up to 3600 N. If your load requires less force, the 63 mm bore offers 1402 N drive and 2200 N holding; for heavier loads, the 100 mm bore provides 3681 N drive and 5500 N holding. Always verify your load is under 3600 N, and allow at least 0.5 seconds for the lock to engage or release after pressure balancing. When replacing a unit, match the 175 mm stroke, PT3/8 cylinder port, M20x1.5 rod thread, and mounting style (Basic, LB, FA, or TC).
Quick checklist
The integrated spring-applied collet instantly clamps the rod, providing a 3600 N bidirectional static holding force to keep the load in position. It is a fail-safe hold, not a dynamic brake, so it must only be engaged after the rod has completely stopped moving.
The double-rod design delivers equal drive force in both directions: 2268 N at 0.5 MPa and 3175 N at 0.7 MPa, with a maximum drive force of 324 kgf. This drive force is separate from the 3600 N static holding force of the rod lock.
