Airtac BSE Clamp Standard Cylinder BSE40X75
The AirTAC Airtac BSE Clamp Standard Cylinder BSE40X75 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, 75mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE40X75
The AirTAC BSE40X75 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 automatically, delivering a 900 N bidirectional static holding force. If air pressure drops or an E-stop trips, the rod stays securely locked at its stopped position.
This fail-safe mechanism relies on a separate G1/8 release port, keeping the lock function entirely distinct from the adjustable air cushions at both ends. Operating pressure is capped at 0.7 MPa, and the cylinder body accepts standard SE mounting accessories except for FTC. This specific SKU lacks a magnet, so it does not support position sensing.
Rod Lock — 900 N Static Holding (Ø40mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE40X75 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 BSE40X75 Is Used
Vertical Lift Platforms
Holds a 900 N raised vertical platform securely in place during air loss, preventing sudden descent while handling light materials.
Tooling Clamp Hold
Maintains 900 N of clamping force on a machined part if the main air supply is exhausted, ensuring the workpiece stays fixed for safe clearing.
Pallet Stop Gate
Provides a hard stop for incoming pallets and locks instantly via the collet if the E-stop is hit, holding the 900 N load without drifting backward.
Is the Airtac BSE Clamp Standard Cylinder BSE40X75 the Right Cylinder?
Verify your load does not exceed the 900 N holding force. If you need less drive force, stepping down to the 32 mm bore yields 402 N push at 0.5 MPa and 600 N holding. If you need more, the 50 mm bore provides 982 N push at 0.5 MPa and 1400 N holding. 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. To replace this unit, match the 40 mm bore, 75 mm stroke, PT1/4 port, and basic mounting.
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 BSE40X75 FAQ
The spring-applied collet clamps the rod instantly upon air loss, providing 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.
No, the 30 mm adjustable air cushions only decelerate the drive motion; the 900 N holding force comes solely from the spring collet. The holding force is fixed by the mechanical lock and cannot be regulated by pressure.
