Airtac BSE Clamp Standard Cylinder BSE100X450S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE100X450S 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, 450mm stroke, PT1/2 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE100X450S
The AirTAC BSE100X450S is a double-acting single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A collet clamps the 25 mm rod to deliver a 5500 N bidirectional static holding force with zero live air required. Operating pressure is capped at 0.7 MPa, and a separate G1/8 release port unlocks the mechanism.
This 100 mm bore, 450 mm stroke unit includes a -S magnet for CMSE reed or DMSE electronic sensors. The lock is a fail-safe holding device, not a dynamic brake; engage it only after the piston stops and release it only when pressures are balanced, allowing at least 0.5 s before moving.
Rod Lock — 5500 N Static Holding (Ø100mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE100X450S 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 BSE100X450S Is Used
Injection Mold Platens
Holds a 5000 N vertical mold platen securely in place during an E-stop or air loss, preventing uncontrolled descent while utilizing the 5497 N push drive force for normal movements.
Pallet Stacker Arrestor
Locks a heavy goods pallet at a 450 mm raised transfer height. The 5500 N collet clamp engages only after the conveyor stops, ensuring the load stays put without needing continuous air pressure.
Machine Tool Guard
Maintains a heavy safety guard open during maintenance. If the 0.7 MPa air supply drops, the fail-safe collet immediately clamps the rod, keeping the 450 mm opening secure against gravity.
Is the Airtac BSE Clamp Standard Cylinder BSE100X450S the Right Cylinder?
Verify your suspended load is safely below the 5500 N holding force. If you need less holding capacity, the 80 mm bore offers 2513 N push at 0.5 MPa and 3600 N hold; for heavier rigs, the 125 mm bore provides 6136 N push at 0.5 MPa and 8600 N hold. At 450 mm stroke, use a guide rail to prevent side-load damage to the extruded aluminum barrel.
This configuration uses a PT1/2 cylinder port, M20x1.5 rod thread, and 36 mm adjustable air cushions at both ends. Standard SE mounting accessories fit this body except FTC. The lock releases via 0.15-0.7 MPa air at the G1/8 port.
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 BSE100X450S FAQ
The drive force is 3927 N push and 3681 N pull at 0.5 MPa, or 5497 N push at 0.7 MPa (max 561 kgf). The separate static holding force of the spring-applied rod lock is 5500 N.
The lock is spring-applied and air-released via a G1/8 port at 0.15-0.7 MPa. You must balance pressures on both sides of the piston before releasing, and allow at least 0.5 seconds for full release before moving the cylinder.
