Airtac BSE Clamp Standard Cylinder BSE40X100S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE40X100S 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, 100mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE40X100S
The AirTAC BSE40X100S is a double-acting, single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. It delivers a bidirectional static holding force of 900 N to prevent drift on air loss. Operating pressure is capped at 0.7 MPa, and the lock uses a separate G1/8 release port.
The collet lock engages automatically to hold the load in both directions without live air. You must engage the lock only after the rod stops completely and release it only when pressures are balanced, allowing at least 0.5 s for full release. The extruded aluminum barrel has no external tie rods, and the -S magnet supports CMSE reed and DMSE electronic sensors.
Rod Lock — 900 N Static Holding (Ø40mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE40X100S 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 BSE40X100S Is Used
Vertical Lift Hold
Holds a 900 N vertical elevator carriage firmly in place during an E-stop or pressure drop, preventing uncontrolled descent.
Tool Clamp Lock
Maintains 628 N of push clamping force on a machining fixture by locking the 40 mm rod instantly if the main air supply is exhausted.
Gate Stop Position
Keeps a pneumatic pallet conveyor gate securely closed with a fail-safe collet grip, ensuring it stays put during full air loss.
Is the Airtac BSE Clamp Standard Cylinder BSE40X100S the Right Cylinder?
Verify your load does not exceed the 900 N holding force. If you need less holding power, the 32 mm bore offers 402 N push at 0.5 MPa and a 600 N hold. If you need more, the 50 mm bore provides 982 N push at 0.5 MPa and a 1400 N hold. Always engage the lock only after the rod stops, and allow at least 0.5 s for release when pressures are balanced.
For this 100 mm stroke, side-load risks are minimal but ensure adequate guide support for heavier radial loads. This configuration includes a PT1/4 cylinder port, an M12x1.25 rod thread, and a -S magnet. Standard SE mounting accessories fit this cylinder perfectly, except for the FTC foot mount.
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 BSE40X100S FAQ
The spring-applied collet clamps the rod instantly on 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, with a max drive of 90 kgf.
You must supply 0.15-0.7 MPa to the separate G1/8 release port only after the pressures on both sides of the piston are balanced. Allow at least 0.5 s for the collet to fully release before commanding any movement.
