Airtac BSE Clamp Standard Cylinder BSE100X150S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE100X150S 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, 150mm stroke, PT1/2 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE100X150S
The AirTAC BSE100X150S is a double-acting, single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A collet clamps the Ø25 mm piston rod automatically, delivering a 5500 N bidirectional static holding force. If air pressure drops or an E-stop trips, the lock engages instantly to hold the load safely in place.
Operating pressure is capped at 0.15-0.7 MPa, and the lock is released via a separate G1/8 port. This model includes a magnet (-S) for use with CMSE reed and DMSE electronic sensors. The lock is a holding device, not a dynamic brake, and must only engage after the rod has fully stopped.
Rod Lock — 5500 N Static Holding (Ø100mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE100X150S 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 BSE100X150S Is Used
Heavy Pallet Lifters
Holds a 500 kg vertical elevator carriage securely mid-stroke with 5500 N of fail-safe force if plant air is suddenly exhausted, preventing a catastrophic free-fall.
Injection Molding Extraction
Suspends heavy molded parts over the press bed during retraction; the spring collet locks the rod instantly on E-stop, ensuring parts do not drop onto the mold.
Pallet Stop Gates
Maintains a raised stop block position on heavy-duty packaging conveyors, using the 5500 N hold to resist dynamic impact forces from incoming pallets during downtime.
Is the Airtac BSE Clamp Standard Cylinder BSE100X150S the Right Cylinder?
Verify your suspended load does not exceed the 5500 N holding force. If your load is lighter, the adjacent BSE80 bore offers 2513 N push at 0.5 MPa and a 3600 N hold. For heavier loads, the BSE125 provides 6136 N push at 0.5 MPa and an 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 before moving.
This 150 mm stroke configuration uses a PT1/2 cylinder port and an M20x1.5 rod thread. SE mounting accessories fit this body perfectly except for FTC. Because this is a 100 mm bore, you can replace it by matching the 100 mm bore, 150 mm stroke, PT thread, and magnet option.
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 BSE100X150S FAQ
The lock is spring-applied and air-released, meaning it clamps the rod automatically if air is lost, providing a 5500 N static hold. The drive force is separate: 3927 N push at 0.5 MPa, 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a maximum drive of 561 kgf at 0.7 MPa.
You must first bring the cylinder to a complete stop, as the lock is not a dynamic brake. Next, balance the air pressures on both sides of the piston. Finally, supply 0.15-0.7 MPa to the separate G1/8 release port and wait at least 0.5 seconds before commanding movement.
