The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED100X300S 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 5500 N in either direction if air is lost. Ø100mm bore, 300mm stroke, PT1/2 ports, G1/8 lock-release.
The AirTAC BSED100X300S 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 3681 N each way at 0.5 MPa and 5153 N at 0.7 MPa. The fail-safe collet clamps the 25 mm rod with 5500 N of static holding force, securing loads instantly when air is lost or an E-stop is tripped.
This 100 mm bore actuator uses a dedicated G1/8 release port and operates at 0.15-0.7 MPa. The rear rod is ideal for mounting external flags or tooling while resisting rotation. Equipped with a magnet (-S), it supports CMSE reed and DMSE electronic sensors for mid-stroke positioning.
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 BSED100X300S 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 | 3682 N |
| 0.7 MPa (max) | 5154 N |
| Max drive (@0.7 MPa) | 526 kgf |
A rod exits both ends, so force is equal on extend and retract. Drive force is separate from the 5500 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 550 kg vertical load mid-stroke with 5500 N of fail-safe force, preventing drops during pressure loss while delivering 5153 N of equal lifting and lowering drive.
The double-rod design resists rotation for precision tooling on the rear rod, while the collet lock secures the 25 mm rod instantly when the spindle stops.
Provides 3681 N of both-way thrust at 0.5 MPa to push and retract diverter arms, locking the 300 mm stroke in place to hold heavy pallets during indexing.
Select this 100 mm bore model when your application requires both-way symmetric thrust and a robust fail-safe hold. Verify your load does not exceed the 5500 N static holding capacity. If you need less force, the 80 mm bore provides 2268 N at 0.5 MPa and 3600 N of hold; if you need more, the 125 mm bore offers 5734 N at 0.5 MPa and 8600 N of hold.
Always engage the lock only after the rod completely stops, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds. For this 300 mm stroke, use a guide to prevent side loads and ensure smooth rod travel. Replacement requires matching the 100 mm bore, 300 mm stroke, PT1/2 port, and mounting style.
Quick checklist
The integrated spring-applied collet immediately clamps the 25 mm rod, providing 5500 N of bidirectional static holding force to keep the load in position with no live air. It is a fail-safe hold, not a dynamic brake, so it must only engage after the rod stops.
The double-rod design delivers equal both-way drive force of 3681 N at 0.5 MPa and 5153 N at 0.7 MPa (max 525 kgf). It operates at speeds of 30-800 mm/s, uses a PT1/2 cylinder port, and has a separate G1/8 lock-release port.
