Airtac BSE Clamp Standard Cylinder BSE40X175S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE40X175S 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 BSE40X175S
The AirTAC BSE40X175S is a double-acting, single-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It delivers a 900 N bidirectional static holding force with zero live air, ensuring suspended loads stay exactly where they stopped if pressure drops. Operating pressure is capped at 0.7 MPa, and the 175 mm stroke operates at 30-800 mm/s.
This 40 mm bore unit features a PT1/4 cylinder port and a separate G1/8 lock-release port. The included magnet (-S) supports CMSE reed and DMSE electronic sensors. The lock is a static collet clamp, not a dynamic brake; it must engage only after the rod fully stops, with a minimum 0.5 s release delay once piston 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 BSE40X175S 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 BSE40X175S Is Used
Z-Axis Pick & Place
Holds a 900 N vertical Z-axis load on an electronics pick and place head instantly if shop air exhausts, preventing crashes while the 879 N drive force handles rapid 175 mm strokes.
Tooling Clamp Hold
Secures a machining fixture position during an E-stop. The spring-applied collet locks the 16 mm rod, maintaining the exact 175 mm extension without relying on live air.
Pallet Stop Gate
Acts as a fail-safe stop gate on a packaging conveyor. The 900 N holding force keeps the 40 mm rod rigidly extended against accumulating pallets even during a complete pneumatic failure.
Is the Airtac BSE Clamp Standard Cylinder BSE40X175S the Right Cylinder?
Verify your suspended load requires 900 N or less of holding force. If you need less drive power, the 32 mm bore offers a 402 N push at 0.5 MPa and a 600 N hold; if you need more, step up to the 50 mm bore for a 982 N push at 0.5 MPa and a 1400 N hold. For this 175 mm stroke, guide any side loads to prevent binding.
To replace safely, match the 40 mm bore, 175 mm stroke, PT1/4 porting, and -S magnet. SE mounting accessories fit this ISO 15552 body perfectly, except FTC. Always balance piston pressures before unlocking, allowing at least 0.5 s for the collet to release.
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 BSE40X175S FAQ
The spring-applied collet clamps the rod instantly upon air loss, delivering a 900 N static holding force. The drive forces are 628 N push and 528 N pull at 0.5 MPa, 879 N push at 0.7 MPa, and a maximum drive of 90 kgf. Holding force is completely separate from drive force.
The lock is not a dynamic brake. You must engage it only after the rod stops moving. To release, balance the air pressures on both sides of the piston, then supply 0.15-0.7 MPa to the separate G1/8 release port, allowing at least 0.5 seconds for the collet to fully clear before commanding motion.
