Airtac BSE Clamp Standard Cylinder BSE40X225S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE40X225S 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, 225mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE40X225S
The AirTAC BSE40X225S is a double-acting single-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A collet clamps the 16 mm rod to deliver a 900 N bidirectional static holding force with zero live air. This fail-safe mechanism prevents drift in vertical or suspended loads the moment pressure drops or an E-stop trips.
Operating pressure is capped at 0.15-0.7 MPa, lower than a standard SE cylinder, and a separate G1/8 release port unlocks the mechanism. The lock is a holding device, not a dynamic brake; engage it only after the rod stops, balance pressures across the piston, and allow at least 0.5 s for full release before resuming motion. The -S option provides a magnet for 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 BSE40X225S 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 BSE40X225S Is Used
Vertical Pneumatic Lifts
Holds a 900 N vertical load in place instantly if air pressure drops, preventing sudden crashes in packaging pick-and-place units.
Tooling Clamp Hold
Maintains 900 N of clamping force on a machining fixture during air loss, keeping the workpiece secured while the spindle spins down.
Pallet Stop Gate
Locks a 16 mm rod to halt pallet traffic securely during an E-stop, ensuring the gate stays rigidly extended until pressure is restored.
Is the Airtac BSE Clamp Standard Cylinder BSE40X225S the Right Cylinder?
Verify your suspended load does not exceed the 900 N holding force, and that your drive requirement fits within the 628 N push at 0.5 MPa or 879 N at 0.7 MPa. If you need less force, the adjacent 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 balance pressures before releasing the lock to prevent sudden rod jumps. When matching this unit, confirm the 225 mm stroke, PT1/4 cylinder port, M12x1.25 rod thread, and your required SE-compatible mounting (except FTC). At 225 mm stroke, use external guides to prevent side loads from wearing the 30 mm cushion seals.
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 BSE40X225S FAQ
The lock is spring-applied and fail-safe. If air is lost or exhausted, the collet immediately clamps the rod, providing a 900 N bidirectional static hold at whatever position it stopped. It is not a dynamic brake; the rod must be stopped before engaging the lock.
The drive force is 628 N push and 528 N pull at 0.5 MPa, or 879 N push at 0.7 MPa, yielding a maximum drive of 90 kgf. The integrated rod lock provides a separate 900 N static holding force with no live air required.
