Airtac BSE Clamp Standard Cylinder BSE100X125
The AirTAC Airtac BSE Clamp Standard Cylinder BSE100X125 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, 125mm stroke, PT1/2 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE100X125
The AirTAC BSE100X125 is a double-acting ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. It delivers a massive 5500 N bidirectional static holding force, ensuring suspended loads remain safely fixed the instant air pressure is lost or an E-stop is triggered. Operating pressure is capped at 0.7 MPa, and the lock mechanism relies on a separate G1/8 release port rather than the main cylinder ports.
This 100 mm bore unit provides 3927 N of push force at 0.5 MPa and uses a 36 mm adjustable air cushion at both ends to absorb impact. Because this specific SKU lacks a magnet, it does not support position sensing without modification. The ISO 15552 mounting interface ensures standard SE accessories fit perfectly, except for FTC variants which are incompatible with the lock housing.
Rod Lock — 5500 N Static Holding (Ø100mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE100X125 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.

Where the Airtac BSE Clamp Standard Cylinder BSE100X125 Is Used
Palletizer Lift Arm
Holds a heavy palletizer lift arm mid-stroke with 5500 N of fail-safe force, preventing catastrophic drops if the main air supply drops below 0.15 MPa.
Injection Mold Clamp
Secures a suspended injection mold tool with the spring-applied collet, ensuring the 5497 N drive force does not drift downward during an emergency stop.
Heavy Pallet Stop Gate
Blocks a heavy goods conveyor lane with a 3927 N push force at 0.5 MPa, then relies on the lock to keep the gate raised without consuming live air.
Is the Airtac BSE Clamp Standard Cylinder BSE100X125 the Right Cylinder?
Verify your load does not exceed the 5500 N static holding force, and ensure the required thrust is met by the 5497 N push force at 0.7 MPa. If you need less force, the 80 mm bore neighbor offers 2513 N push at 0.5 MPa with a 3600 N holding force. If you need more, the 125 mm bore provides 6136 N push at 0.5 MPa and 8600 N holding force.
Always engage the lock only after the piston rod has completely stopped moving, and release it only when pressures on both sides of the piston are balanced, allowing at least 0.5 seconds for full release. When replacing a unit, match the 100 mm bore, 125 mm stroke, PT1/2 port thread, and mounting style. For any stroke over 300 mm, add external guide rails to prevent side-load wear on the seals.
Quick checklist
- ✓ Load to hold ≤ 5500 N?
- ✓ Fail-safe hold on air loss / E-stop needed
- ✓ Lock engaged only when stopped
- ✓ G1/8 release-air line available
- ✓ Magnet (-S) for CMSE/DMSE sensors?
Installation & Safety Notes
- check Engage the lock only after the rod has stopped — not as a dynamic brake.
- check Release only when both piston sides are pressure-balanced.
- check Allow ≥0.5 s for full release before commanding motion.
- check Feed the G1/8 release port with 0.15–0.7 MPa clean air.
- check Add safety-rated controls for man-rated / overhead loads.
- check Use SE mounting accessories (FTC excepted).
Airtac BSE Clamp Standard Cylinder BSE100X125 FAQ
The drive force at 0.5 MPa is 3927 N push and 3681 N pull. At 0.7 MPa, the push force is 5497 N, equating to a maximum drive of 561 kgf. The integrated rod lock provides a separate 5500 N bidirectional static holding force with no live air required.
The lock is spring-applied and fail-safe, meaning a collet clamps the 25 mm rod instantly upon air loss or E-stop, holding the load in both directions. To release it safely, balance pressures on both sides of the piston, supply 0.15-0.7 MPa to the separate G1/8 release port, and wait at least 0.5 seconds before moving.
