Airtac BSE Clamp Standard Cylinder BSE40X100
The AirTAC Airtac BSE Clamp Standard Cylinder BSE40X100 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 BSE40X100
The AirTAC BSE40X100 is a double-acting ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A collet clamps the 16mm piston rod automatically, providing a 900 N bidirectional static holding force with zero live air required. 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 0.15-0.7 MPa, and the lock is released via a separate G1/8 port. Remember this is a static hold, not a dynamic brake: engage the lock only after the rod stops, and allow at least 0.5 s for full release after balancing piston pressures. This specific SKU lacks a magnet, so position sensing is not available.
Rod Lock — 900 N Static Holding (Ø40mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE40X100 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 BSE40X100 Is Used
Vertical Lift Hold
Secures a 40mm rod vertical lift stage mid-travel. The 900 N collet lock prevents a suspended gripper from crashing down during an air loss event.
Pneumatic Tool Clamp
Holds a machined part firmly under the 879 N drive force, then locks the 100mm stroke position so the clamp never releases if shop air exhausts.
Sorter Gate Stop
Blocks items on a packaging line. The spring-applied collet keeps the gate extended during an E-stop, holding against impacts up to 900 N without drifting.
Is the Airtac BSE Clamp Standard Cylinder BSE40X100 the Right Cylinder?
Verify your load to hold does not exceed the 900 N static rating. If you need less drive and hold, the 32mm bore offers 402 N push at 0.5 MPa and 600 N holding force. If you need more, stepping up to the 50mm bore provides 982 N push at 0.5 MPa and 1400 N holding force. When replacing, match the 40mm bore, 100mm stroke, PT1/4 cylinder port, and your mounting choice. SE mounting accessories fit perfectly except FTC. Since the stroke is 100mm, side-load is minimal, but always guide the rod laterally for rigid loads.
This SKU has no -S magnet, meaning CMSE or DMSE position sensors cannot be used. To safely unlock the collet, balance pressures on both sides of the piston and supply 0.15-0.7 MPa to the G1/8 release port before moving.
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 BSE40X100 FAQ
The drive force at 0.5 MPa is 628 N push and 528 N pull. At the 0.7 MPa ceiling, push is 879 N (max 90 kgf). The integrated rod lock provides a separate 900 N bidirectional static holding force with no live air.
The lock is spring-applied and fail-safe. If air is lost or exhausted, a collet clamps the rod instantly, holding the load in both directions up to 900 N. It is not a dynamic brake; engage it only after the rod stops, and allow >=0.5 s for release.
