Airtac BSE Clamp Standard Cylinder BSE40X800
The AirTAC Airtac BSE Clamp Standard Cylinder BSE40X800 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, 800mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE40X800
The AirTAC BSE40X800 is a double-acting ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A collet clamps the Ø16 mm piston rod, delivering a bidirectional static holding force of 900 N with zero live air. This fail-safe mechanism ensures suspended loads remain exactly where they stopped if air pressure drops or an E-stop is hit.
Operating pressure is capped at 0.7 MPa, and the lock unlocks via a dedicated G1/8 release port. Because it uses the standard SE extruded aluminum body, all SE mounting accessories fit this model except FTC. This specific SKU lacks a magnet, so position sensing is not available without a different variant.
Rod Lock — 900 N Static Holding (Ø40mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE40X800 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 BSE40X800 Is Used
Vertical Lift Hold
Holds a 900 N vertical machining axis safely in place during air loss, preventing a 90 kgf payload from drifting downward.
Tool Clamp Retention
Keeps a clamped fixture locked on an automated lathe if shop air exhausts, ensuring the workpiece stays secured at 800 mm extension.
Pallet Gate Stop
Maintains a raised pneumatic pallet gate rigidly in position during an E-stop, resisting dynamic shifts up to 900 N without needing live air.
Is the Airtac BSE Clamp Standard Cylinder BSE40X800 the Right Cylinder?
Verify your suspended load does not exceed the 900 N holding force. If you need less drive force, step down to the BSE32 bore, which provides a 402 N push at 0.5 MPa and a 600 N hold. If your load exceeds the 40 mm bore's 90 kgf maximum drive, step up to the BSE50, offering a 982 N push at 0.5 MPa and a 1400 N hold. Always engage the collet only after the rod completely stops, and release it only when piston pressures are balanced, allowing at least 0.5 s before moving. For this 800 mm stroke, use a guide to prevent side-load damage to the barrel. Match the PT1/4 port, 800 mm stroke, and mounting choice when replacing.
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 BSE40X800 FAQ
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 90 kgf drive at 0.7 MPa. The separate static holding force of the spring collet lock is 900 N.
If air is lost, the spring collet immediately clamps the rod with 900 N of bidirectional force, holding the load without live air. To release, apply 0.15-0.7 MPa to the G1/8 release port, balance piston pressures, and wait at least 0.5 s before moving.
