Airtac BSE Clamp Standard Cylinder BSE40X175
The AirTAC Airtac BSE Clamp Standard Cylinder BSE40X175 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, 175mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE40X175
The AirTAC BSE40X175 is a double-acting, single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A collet mechanism delivers a bidirectional static holding force of 900 N with zero live air required. If pressure drops or an E-stop trips, the rod is securely clamped in place. Operating pressure is capped at 0.7 MPa.
The lock uses a separate G1/8 release port to overcome the spring and free the rod. Because this unit lacks the -S magnet option, it does not support position sensing. The lock is a holding device, not a dynamic brake; it must be engaged only after the piston stops and released only when pressures are balanced.
Rod Lock — 900 N Static Holding (Ø40mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE40X175 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 BSE40X175 Is Used
Vertical Lift Hold
Secures a 900 N vertical lifting stage on a packaging machine the instant air is exhausted, preventing uncontrolled drops.
Tool Clamp Lock
Holds a machining fixture in place during an emergency stop, maintaining the 900 N grip without relying on continuous air pressure.
Pallet Stop Gate
Keeps a pneumatic pallet stop gate firmly extended during a system fault, locking the 40 mm rod solid until pressure is restored.
Is the Airtac BSE Clamp Standard Cylinder BSE40X175 the Right Cylinder?
Verify your suspended load requires 900 N or less of holding force. If you need less drive and hold, the 32 mm bore offers 402 N push at 0.5 MPa and 600 N hold. If your load exceeds this capacity, step up to the 50 mm bore, providing 982 N push at 0.5 MPa and 1400 N hold. Always allow at least 0.5 s for full release before commanding motion. To match this SKU exactly on replacement, confirm the 40 mm bore, 175 mm stroke, PT1/4 port, and no magnet. At 175 mm stroke, side loads are minimal, but always ensure rigid guidance for optimal seal life.
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 BSE40X175 FAQ
The spring-applied collet immediately clamps the rod, providing a 900 N bidirectional static hold. The lock is fail-safe, meaning it secures the load without any live air. It is a holding lock, not a dynamic brake, so it must only engage after the rod has fully stopped.
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 integrated rod lock provides a separate 900 N static holding force with no live air required.
