Airtac BSE Clamp Standard Cylinder BSE40X1000
The AirTAC Airtac BSE Clamp Standard Cylinder BSE40X1000 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, 1000mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE40X1000
The AirTAC BSE40X1000 is a double-acting, single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. Because the clamping collet engages automatically upon air loss, it delivers a bidirectional static holding force of 900 N with zero live air required. Operating pressure is capped at 0.7 MPa.
This specific 1000 mm stroke unit exceeds the 800 mm standard maximum, making it a made-to-order item. It features a Ø16 mm rod, an M12x1.25 rod-end thread, PT1/4 cylinder ports, and a separate G1/8 lock-release port. This SKU does not include a 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 BSE40X1000 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.

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 BSE40X1000 Is Used
Vertical Pneumatic Lift
Holds a 900 N vertical lift carriage firmly in place during an E-stop or pressure drop, preventing gravity-driven drift on long 1000 mm travel axes.
Overhead Tool Clamp
Keeps a machining tool clamped mid-stroke if air supply fails, ensuring the 879 N drive force does not cause uncontrolled tool drops.
Pallet Stop Gate
Maintains a conveyor pallet stop gate in its exact extended position without consuming air, resisting dynamic impacts up to the 900 N limit.
Is the Airtac BSE Clamp Standard Cylinder BSE40X1000 the Right Cylinder?
Verify your suspended load requires 900 N or less of holding force. If you need less drive power, stepping down to a bore 32 yields a 402 N push at 0.5 MPa and 600 N hold; stepping up to a bore 50 provides a 982 N push at 0.5 MPa and 1400 N hold. Always engage the lock only after the piston rod completely stops, and release it only when pressures are balanced, allowing at least 0.5 s before moving. When replacing, match the 40 mm bore, 1000 mm stroke, PT thread, and mounting choice. Because this stroke is 1000 mm, you must use external guide rails to prevent excessive side-loading on the rod. Note that SE mounting accessories fit BSE bodies except 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 BSE40X1000 FAQ
The lock is spring-applied and air-released. If air is lost or exhausted, a collet clamps the rod, providing a 900 N bidirectional static holding force. It is not a dynamic brake; engage it only after the rod stops.
Drive forces are 628 N push and 528 N pull at 0.5 MPa, and 879 N push at 0.7 MPa (max 90 kgf). The static holding force of the lock is 900 N, which is separate from the drive force.
