Airtac BSE Clamp Standard Cylinder BSE100X225
The AirTAC Airtac BSE Clamp Standard Cylinder BSE100X225 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, 225mm stroke, PT1/2 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE100X225
The AirTAC BSE100X225 is a double-acting, single-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It delivers a 5500 N bidirectional static holding force with no live air required, ensuring suspended loads stay exactly where they stopped if air pressure drops. Operating pressure is capped at 0.7 MPa, and the cylinder port is PT1/2.
This unit uses a separate G1/8 release port to unlock the internal collet. Because the lock is fail-safe, it engages automatically upon air loss or E-stop activation. This specific SKU lacks a magnet, meaning no CMSE or DMSE position sensors can be fitted. SE-compatible mounting accessories fit this body perfectly, except for the FTC variant.
Rod Lock — 5500 N Static Holding (Ø100mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE100X225 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.

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 BSE100X225 Is Used
Press Feeders
Holds a 500 kg steel blank suspended at 225 mm stroke during press indexing, using the 5500 N fail-safe collet to prevent a drop if shop air exhausts.
Pallet Stops
Secures a loaded pallet at a transfer station; the spring-applied lock clamps the 25 mm rod instantly during an E-stop, halting movement without live air.
Tooling Stands
Locks heavy machining tooling in a fixed extended position, relying on the 5500 N static hold rather than constant air pressure to maintain placement.
Is the Airtac BSE Clamp Standard Cylinder BSE100X225 the Right Cylinder?
Verify your load requires a holding force at or below 5500 N and a drive force up to 5497 N at 0.7 MPa. If you need less force, the 80 mm bore offers 2513 N push at 0.5 MPa and 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.
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 100 mm bore, 225 mm stroke, PT thread, and mounting choice. Because this stroke is under 300 mm, standard side-load risks are minimal, but always verify rod alignment.
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 BSE100X225 FAQ
The integrated rod lock is spring-applied and fail-safe. If air is lost or exhausted, the collet immediately clamps the piston rod, providing a 5500 N bidirectional static holding force to keep the load in place without any live air.
The BSE100X225 drive force is 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, with a max drive of 561 kgf. The separate static holding force of the rod lock is 5500 N.
