Airtac BSE Clamp Standard Cylinder BSE40X150S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE40X150S 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 Ø16mm rod and holds up to 900 N in either direction — no drift. Ø40mm bore, 150mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE40X150S
The AirTAC BSE40X150S is a double-acting ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A collet clamps the 16 mm rod automatically, delivering a 900 N bidirectional static holding force with zero live air required. This fail-safe mechanism ensures suspended loads remain exactly where they stopped if air pressure drops or an E-stop is triggered.
Operating pressure for the drive is capped at 0.7 MPa, and the lock is managed via a dedicated G1/8 release port. Because it uses the standard SE extruded aluminum body, all SE mounting accessories fit perfectly except FTC. The -S option includes a magnet for precise position sensing with CMSE reed or DMSE electronic sensors.
Rod Lock — 900 N Static Holding (Ø40mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE40X150S 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa (max) | 880 N | — |
| Max drive (@0.7 MPa) | 90 kgf | |
Drive force is separate from the 900 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 BSE40X150S Is Used
Vertical Lift Gates
Holds a 90 kg vertical lift gate securely in mid-air using the 900 N fail-safe collet, preventing a sudden crash if the compressed air supply is lost during a factory blackout.
Tooling Clamp Hold
Maintains 628 N of push force to position a machining fixture, then locks the 16 mm rod to keep the tooling clamp rigidly fixed against vibration when the drive air is exhausted.
Pallet Stopper Arm
Acts as a fail-safe stop arm on a packaging conveyor, locking into place via the collet to hold pallets stationary during an emergency stop without relying on continuous air pressure.
Is the Airtac BSE Clamp Standard Cylinder BSE40X150S the Right Cylinder?
Verify your load requires 900 N or less of holding force; if you need less, step down to the BSE32 bore (402 N push @0.5 MPa, 600 N hold). If your load demands more, step up to the BSE50 bore (982 N push @0.5 MPa, 1400 N hold). The lock must only engage after the rod fully stops, and release only when piston pressures are balanced—allow at least 0.5 s before moving. When ordering a replacement, match the 40 mm bore, 150 mm stroke, PT1/4 cylinder port, and the -S magnet option. For this 150 mm stroke, ensure adequate guiding to prevent side-load damage to the barrel.
Quick checklist
- ✓ Load to hold ≤ 900 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 BSE40X150S FAQ
The spring-applied collet immediately clamps the rod, delivering a 900 N bidirectional static hold with no live air. It is a fail-safe lock, not a dynamic brake, so it only engages after the rod stops.
The drive force is 628 N push and 528 N pull at 0.5 MPa, and 879 N push at 0.7 MPa (max 90 kgf). The static holding force of the rod lock is 900 N. Always allow at least 0.5 s for full release before moving.
