Airtac BSE Clamp Standard Cylinder BSE40X80
The AirTAC Airtac BSE Clamp Standard Cylinder BSE40X80 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 BSE40X80
The AirTAC BSE40X80 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, ensuring your load stays exactly where it stopped if air pressure drops. Operating pressure is capped at 0.7 MPa, and the lock uses a dedicated G1/8 release port.
This unit features a 40 mm bore, 80 mm stroke, and a 30 mm adjustable air cushion at both ends. The rod lock is a collet mechanism, not a dynamic brake. You must engage it only after the piston stops, and release it only when pressures are balanced, allowing at least 0.5 s before moving. This SKU has no magnet, so it does not support position sensors.
Rod Lock — 900 N Static Holding (Ø40mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE40X80 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.

Specifications follow the official AirTAC BSE datasheet. The lock uses the SE standard body; SE mounting accessories fit BSE except FTC. Port options: PT (standard) / G (BSPP); lock-release port is G1/8.
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 BSE40X80 Is Used
Vertical Pneumatic Lift
Holds a 900 N vertical lift gate in place instantly if shop air is exhausted, preventing gravity-driven drift.
Tooling Clamp
Secures a machining fixture with 628 N of push force at 0.5 MPa, then locks the 16 mm rod to prevent droop during E-stop.
Pallet Stopper
Acts as a hard stop on a packaging conveyor, using the spring-applied collet to maintain its position securely against bumps.
Is the Airtac BSE Clamp Standard Cylinder BSE40X80 the Right Cylinder?
Verify your suspended load requires 900 N or less of holding force. If you need less holding capacity, the 32 mm bore offers a 600 N hold and 402 N push at 0.5 MPa. If your load exceeds 900 N, step up to the 50 mm bore, which provides a 1400 N hold and 982 N push at 0.5 MPa. The cylinder port is PT1/4, while the lock-release port is G1/8. When replacing, match the 40 mm bore, 80 mm stroke, and mounting style. SE mounting accessories fit this body perfectly except for FTC.
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 BSE40X80 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 drive of 90 kgf. The separate static holding force of the rod lock is 900 N.
The lock is spring-applied and fails safe, immediately clamping the rod with 900 N of bidirectional force. To release it, supply 0.15-0.7 MPa to the G1/8 port only after balancing piston pressures, waiting 0.5 s.
