The AirTAC Airtac BSE Clamp Standard Cylinder BSE50X175 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 Ø20mm rod and holds up to 1400 N in either direction — no drift. Ø50mm bore, 175mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.
The AirTAC BSE50X175 is a double-acting ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A collet clamps the Ø20 mm rod, delivering a 1400 N bidirectional static holding force. This fail-safe mechanism holds your load securely in both directions with zero live air required.
Operating pressure is capped at 0.7 MPa, and the lock unlocks via a separate G1/8 port. The cylinder port is PT1/4, and it uses adjustable air cushions at both ends. Note that this specific SKU lacks a magnet, so CMSE or DMSE position sensors cannot be used.
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE50X175 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.

| Max drive (@0.7 MPa) | 140 kgf | |
Drive force is separate from the 1400 N static holding force of the lock. BSE operates up to 0.7 MPa. Size with a safety margin.

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 a 1400 N vertical machining head on a CNC grinder, preventing a crash or drop if the 0.7 MPa air supply suddenly exhausts.
Maintains clamping pressure on a workpiece fixture during an emergency stop, keeping the 982 N drive force from drifting.
Holds a heavy pallet transfer gate fixed in place during an E-stop, utilizing the spring-applied collet to resist dynamic shifting.
Verify your suspended load is safely under the 1400 N holding force limit. If you need less force, the 40 mm bore offers 628 N push at 0.5 MPa and 900 N hold. If you need more, the 63 mm bore provides 1559 N push at 0.5 MPa and 2200 N hold. Always engage the lock only after the rod completely stops, and release it only when piston pressures are balanced, allowing at least 0.5 seconds before moving. When replacing, match the 50 mm bore, 175 mm stroke, PT port, and mounting. SE mounting accessories fit this cylinder except FTC.
Quick checklist
The lock is spring-applied and fail-safe. If air is lost or exhausted, the collet instantly clamps the rod, providing a 1400 N bidirectional static hold. It is not a dynamic brake, so engage it only after the rod stops.
The drive force is 982 N push at 0.5 MPa, 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a max drive of 140 kgf. The separate static holding force of the rod lock is 1400 N.
