The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED32X200S combines a double-rod ISO 15552 cylinder — a Ø12mm rod out BOTH ends for equal force both directions — with an integrated spring-applied, air-released ROD LOCK that holds up to 600 N in either direction if air is lost. Ø32mm bore, 200mm stroke, PT1/8 ports, G1/8 lock-release.
The AirTAC BSED32X200S 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 drive force of 345 N each way at 0.5 MPa. The internal collet delivers a bidirectional fail-safe holding force of 600 N.
Because the lock clamps the rod with no live air, the piston remains secured during an E-stop or pressure drop. The integrated -S magnet supports CMSE reed and DMSE electronic sensors for position feedback. A separate G1/8 release port controls the unlock function, operating independently from the PT1/8 cylinder ports.
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 BSED32X200S 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.

Specifications follow the official AirTAC BSED datasheet. Rod thread M10×1.25 both ends. Mounting (BSED): Basic, LB, FA, TC. Port options: PT (standard) / G (BSPP); lock-release port is G1/8.
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 346 N |
| 0.7 MPa (max) | 484 N |
| Max drive (@0.7 MPa) | 49 kgf |
A rod exits both ends, so force is equal on extend and retract. Drive force is separate from the 600 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 600 N vertical load in place instantly if air pressure drops, preventing sudden crashes while the double-rod provides equal lifting and lowering force.
Secures a 345 N workpiece at an exact intermediate position for a machining operation, using the rear rod for anti-rotation stability.
Locks a transfer arm safely mid-cycle during conveyor indexing, ensuring the load stays put without consuming compressed air.
Select this 32 mm bore when an application requires symmetric both-way motion and a 600 N static hold. If your load exceeds 600 N, step up to the 40 mm bore, which provides 528 N both-way drive force at 0.5 MPa and a 900 N holding force. If your load is lighter, there is no smaller BSED bore. Engage the lock only after the rod fully stops, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds. For a direct replacement, match the 200 mm stroke, PT porting, and -S magnet option.
Quick checklist
If air is lost or an E-stop trips, the spring-applied collet clamps the rod immediately, providing a bidirectional static holding force of 600 N with no live air. The lock is a holding device, not a dynamic brake, so it must only engage after the rod stops.
The double-rod design provides equal drive force in both directions: 345 N at 0.5 MPa and 483 N at 0.7 MPa, with a maximum drive of 49 kgf. The fail-safe rod lock provides a separate static holding force of 600 N.
