Airtac BSE Clamp Standard Cylinder BSE40X80S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE40X80S 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, 80mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE40X80S
The AirTAC BSE40X80S is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It delivers a bidirectional static holding force of 900 N with no live air, preventing vertical loads from drifting if pressure drops or an E-stop trips. Operating pressure is capped at 0.7 MPa.
This 40 mm bore, 80 mm stroke unit uses a separate G1/8 release port to unlock the clamping collet. The -S magnet option supports CMSE reed and DMSE electronic sensors for precise position feedback. SE-compatible mounting accessories fit this body, except for FTC.
Rod Lock — 900 N Static Holding (Ø40mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE40X80S 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 BSE40X80S Is Used
Vertical Pneumatic Lift
Holds a 50 kg vertical lift gate firmly in place during an air loss event, relying on the 900 N fail-safe collet grip to prevent uncommanded descent.
Tooling Clamp
Secures a machining fixture under 879 N of push force at 0.7 MPa, while the spring-applied lock ensures the clamp stays engaged if the main air supply is exhausted.
Pallet Stopper
Acts as a mid-stroke stop on a conveyor line, using the 628 N drive force at 0.5 MPa to extend and the mechanical collet to lock position against vibration.
Is the Airtac BSE Clamp Standard Cylinder BSE40X80S the Right Cylinder?
Verify your suspended load requires less than the 900 N static holding force. If you need less drive power, the 32 mm bore offers 402 N push at 0.5 MPa and a 600 N hold. If you need more, step up to the 50 mm bore, providing 982 N push at 0.5 MPa and a 1400 N hold. Always engage the lock only after the rod fully stops, and release it only when piston pressures are balanced, allowing at least 0.5 s before moving. Replace using the exact 40 mm bore, 80 mm stroke, PT1/4 port, and magnet option.
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 BSE40X80S FAQ
It is spring-applied and air-released. If air is lost, a spring pushes a collet to clamp the 16 mm rod, delivering a 900 N bidirectional static holding force. It is not a dynamic brake; engage it only after the rod stops.
The drive force is 628 N push and 528 N pull at 0.5 MPa, or 879 N push at 0.7 MPa, equating to a max 90 kgf drive. The separate static holding force from the lock is 900 N.
