Airtac BSE Clamp Standard Cylinder BSE100X450
The AirTAC Airtac BSE Clamp Standard Cylinder BSE100X450 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 BSE100X450
The AirTAC BSE100X450 is a double-acting ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. It provides a robust 5500 N static holding force, clamping the piston rod bidirectionally to prevent drift whenever air is exhausted or an E-stop trips.
Operating pressure is capped at 0.7 MPa, and the lock unlocks via a separate G1/8 port. This 100 mm bore unit uses a PT1/2 cylinder port, a 25 mm rod with an M20x1.5 thread, and adjustable cushions at both ends. This SKU lacks a magnet, so it does not support position sensing.
Rod Lock — 5500 N Static Holding (Ø100mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE100X450 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 BSE100X450 Is Used
Injection Mold Platens
Secures heavy mold platens mid-stroke. The 5500 N holding force locks instantly on air loss, while 5497 N push at 0.7 MPa drives the heavy tooling.
Palletizer Lift Carriage
Holds a vertical lift carriage in place during E-stop. The fail-safe collet prevents the loaded carriage from crashing down when shop air drops.
Heavy Press Tooling
Maintains exact position for large press tooling. The spring-applied collet locks the 25 mm rod securely, ensuring the tool stays put even with zero live air.
Is the Airtac BSE Clamp Standard Cylinder BSE100X450 the Right Cylinder?
Verify your suspended load requires less than the 5500 N static holding force. If you need less drive power, 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.
At 450 mm stroke, use a guide to prevent side-load damage to the seal and rod. Engage the lock only after the rod fully stops, and release it only when piston pressures are balanced, allowing at least 0.5 s before moving. When replacing, match the 100 mm bore, 450 mm stroke, PT1/2 port, and mounting type. SE accessories fit except FTC.
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 BSE100X450 FAQ
The spring-applied collet engages automatically on air loss, providing 5500 N of bidirectional static holding force. The drive forces are 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a maximum drive of 561 kgf.
The lock is not a dynamic brake. You must engage it only after the rod stops. To release, balance pressures on both sides of the piston, supply 0.15-0.7 MPa to the G1/8 release port, and wait at least 0.5 s before commanding motion.
