The AirTAC Airtac BSE Clamp Standard Cylinder BSE100X250 is a genuine double-acting ISO 15552 cylinder with an integrated spring-applied, air-released ROD LOCK. If air is cut or an E-stop is hit, the collet clamps the Ø25mm rod and holds up to 5500 N in either direction — no drift. Ø100mm bore, 250mm stroke, PT1/2 cylinder ports, G1/8 lock-release port.
The AirTAC BSE100X250 is a double-acting single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A collet clamps the Ø25 mm rod to provide a bidirectional static holding force of 5500 N. This fail-safe mechanism ensures suspended loads remain fixed instantly if air pressure drops or an emergency stop is triggered.
Operating pressure is capped at 0.7 MPa, and the lock unlocks via a separate G1/8 port. The cylinder itself uses a PT1/2 port, runs at 30-800 mm/s, and features 36 mm adjustable air cushions at both ends. This standard SKU lacks a magnet, so position sensing via CMSE or DMSE sensors is not supported without a different order code.
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE100X250 holds its position in both directions when air is lost, exhausted or an E-stop trips. Apply 0.15–0.7 MPa to the G1/8 release port to unlock. Engage the lock only after the rod has stopped (it is not a dynamic brake), and release only when the pressures on both sides of the piston are balanced. Allow at least 0.5 s for full release before moving.

Thread: PT (blank) / G. Mounting (BSE): Basic, LB, FA, FB, CA, CB, CR, TC (FTC is not available on BSE). Related: SE (no lock), BSED (double-rod rod lock). Sensors CMSE/DMSE fit magnetic BSE.
Secures 100-ton press dies in place during air loss. The 5500 N collet lock prevents the heavy tooling from slipping or dropping when the main air supply is exhausted.
Holds a fully loaded 500 kg pallet assembly mid-air. The fail-safe lock engages instantly if the compressor fails, preventing a catastrophic free-fall.
Acts as a hard stop for large automotive castings on a transfer line. The lock holds the 5497 N drive force load firmly during machining cycles without drifting.
Verify your load stays under the 5500 N static holding capacity. If your load is lighter, the 80 mm bore offers 2513 N push at 0.5 MPa and a 3600 N hold. If you need more brute force, the 125 mm bore provides 6136 N push at 0.5 MPa and an 8600 N hold. Always engage the lock only after the rod fully stops, and release it only when piston pressures are balanced, allowing at least 0.5 seconds before moving. At 250 mm stroke, side-load risks are low, but ensure standard guide alignment. SE mounting accessories fit this body perfectly, except for FTC brackets.
Quick checklist
The drive forces at 0.5 MPa are 3927 N push and 3681 N pull. At the 0.7 MPa ceiling, push is 5497 N (max drive 561 kgf). The integrated rod lock provides a separate 5500 N static holding force with no live air required.
The lock is spring-applied and air-released. If air pressure drops below 0.15 MPa, a collet immediately clamps the rod in both directions with 5500 N of force. You must balance piston pressures and supply 0.15-0.7 MPa to the G1/8 release port for at least 0.5 seconds to free it.
