Airtac BSE Clamp Standard Cylinder BSE40X150
The AirTAC Airtac BSE Clamp Standard Cylinder BSE40X150 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 BSE40X150
The AirTAC BSE40X150 is a double-acting single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A collet clamps the 16mm piston rod automatically, delivering a 900N bidirectional static holding force with zero live air required. Operating pressure is capped at 0.7 MPa, and the cylinder port is PT1/4.
This fail-safe mechanism engages instantly if air is exhausted or an E-stop trips, holding the load firmly at its stopped position. The lock is not a dynamic brake; it must engage only after the rod stops. Unlocking requires 0.15-0.7 MPa supplied to the separate G1/8 release port, with at least 0.5s allowed for full release before motion. SE mounting accessories fit this body perfectly, except FTC.
Rod Lock — 900 N Static Holding (Ø40mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE40X150 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 (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 BSE40X150 Is Used
Vertical Pneumatic Lifts
Holds a 900N vertical load securely on an overhead gantry if air pressure drops, preventing sudden crashes during an E-stop event.
Tooling Clamp Station
Maintains 628N of clamping drive force on a machining fixture, locking the 16mm rod instantly to keep the part fixed if supply air is lost.
Pallet Stop Gate
Acts as a mid-conveyor stop barrier; the spring collet locks the rod in place to resist pallet impacts without needing continuous air pressure.
Is the Airtac BSE Clamp Standard Cylinder BSE40X150 the Right Cylinder?
Verify your load stays under the 900N static holding force. If you need less drive, the 32mm bore offers 402N push at 0.5MPa and 600N hold. If you need more, the 50mm bore gives 982N push at 0.5MPa and 1400N hold. This 40mm bore provides 628N push at 0.5MPa, 528N pull, and 879N push at 0.7MPa (90kgf max drive).
Always balance pressures on both sides of the piston before releasing the lock, allowing >=0.5s for the collet to disengage. This specific SKU lacks a magnet (-S), so CMSE or DMSE position sensors cannot be used. When ordering a replacement, match the 150mm stroke, PT1/4 port, and standard mounting. For this 150mm stroke, standard guide rails should be used to prevent side-load wear on the collet.
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 BSE40X150 FAQ
The spring-applied collet clamps the rod immediately, providing a 900N bidirectional static hold. It is a fail-safe holding lock, not a dynamic brake, so it only engages after the rod has stopped moving.
Drive force is 628N push at 0.5MPa, 528N pull at 0.5MPa, and 879N push at 0.7MPa (90kgf max drive). The separate static holding force of the rod lock is 900N.
