Airtac BSE Clamp Standard Cylinder BSE100X300
The AirTAC Airtac BSE Clamp Standard Cylinder BSE100X300 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, 300mm stroke, PT1/2 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE100X300
The AirTAC BSE100X300 is a double-acting, single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. It provides a robust 5500 N static holding force, securing suspended loads in both directions the moment air pressure is lost or an E-stop is triggered. Operating pressure is capped at 0.7 MPa, and the lock unlocks via a dedicated G1/8 port.
This 100mm bore actuator generates 5497 N of drive force at 0.7 MPa while extending up to a 300mm stroke. The lock is a static collet clamp, not a dynamic brake; it must only engage after the rod fully stops. Because this specific SKU lacks a magnet (-S), it cannot host CMSE or DMSE position sensors.
Rod Lock — 5500 N Static Holding (Ø100mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE100X300 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.

Specifications follow the official AirTAC BSE datasheet. The lock uses the SE standard body; SE mounting accessories fit BSE except FTC. Port options: PT (standard) / G (BSPP); lock-release port is G1/8.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa (max) | 5498 N | — |
| Max drive (@0.7 MPa) | 561 kgf | |
Drive force is separate from the 5500 N static holding force of the lock. BSE operates up to 0.7 MPa. Size with a safety margin.

Where the Airtac BSE Clamp Standard Cylinder BSE100X300 Is Used
Press Tooling Clamp
Holds heavy stamping tooling at 300mm extension. The 5500 N collet lock prevents the 100mm rod from drifting downward if shop air suddenly exhausts.
Vertical Lift Platform
Secures a vertical lift stage mid-travel. The spring-applied lock engages instantly on air loss, safely suspending the load without needing live pressure.
Pallet Stop Gate
Acts as a hard stop for heavy pallets on a conveyor. The fail-safe collet ensures the 300mm extended gate remains rigidly locked during emergency power-offs.
Is the Airtac BSE Clamp Standard Cylinder BSE100X300 the Right Cylinder?
Verify your load stays within the 5500 N holding capacity and the 5497 N push force at 0.7 MPa. If your load is lighter, the 80mm bore offers 3518 N push and 3600 N hold; for heavier demands, the 125mm bore provides 8590 N push and 8600 N hold. Always balance pressures on both sides of the piston before releasing the lock, allowing at least 0.5 seconds for full release.
At 300mm stroke, prevent rod side-loading by guiding the load externally. This unit uses a PT1/2 cylinder port and a PT thread form. You can reuse SE-compatible mounting accessories (except FTC) to fit your ISO 15552 interface.
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 BSE100X300 FAQ
The drive force at 0.5 MPa is 3927 N push and 3681 N pull; at 0.7 MPa, push is 5497 N (max drive 561 kgf). The separate static rod-lock provides a 5500 N bidirectional holding force with no live air.
The lock is spring-applied and air-released via a G1/8 port. You must first balance pressures on both sides of the piston, then supply 0.15-0.7 MPa to the release port, allowing at least 0.5 seconds before moving the rod.
