Airtac BSE Clamp Standard Cylinder BSE40X700S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE40X700S 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, 700mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE40X700S
The AirTAC BSE40X700S is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A collet clamps the 16mm rod to deliver a 900 N bidirectional fail-safe holding force with zero live air. Operating pressure is capped at 0.7 MPa, and the lock uses a separate G1/8 release port.
This 40mm bore unit provides 628 N push and 528 N pull at 0.5 MPa, reaching 879 N push at 0.7 MPa. The lock is not a dynamic brake: engage it only after the 700mm stroke stops, and allow at least 0.5s for release once pressures balance. 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 BSE40X700S 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 BSE40X700S Is Used
Vertical Pallet Lift
Holds a raised pallet mid-stroke at 900 N if shop air drops, preventing sudden crashes on packaging lines.
Tooling Clamp
Locks a 700mm extended machining fixture in place during E-stops, keeping the 879 N drive from drifting.
Pallet Stopper Gate
Acts as a fail-safe gate on conveyors, holding the rod rigid against impacting loads when air is exhausted.
Is the Airtac BSE Clamp Standard Cylinder BSE40X700S the Right Cylinder?
Verify your suspended load needs 900 N or less of static hold, while the 879 N push at 0.7 MPa drives it. If you need less drive force, the 32mm bore offers 402 N push at 0.5 MPa and 600 N hold; if you need more, the 50mm bore gives 982 N push at 0.5 MPa and 1400 N hold. Always balance piston pressures before unlocking, allowing >=0.5s for release.
For this 700mm stroke, use a linear guide to prevent side-load wear on the seals and barrel. When replacing, match the 40mm bore, 700mm stroke, PT1/4 cylinder port, and -S magnet. SE mounting accessories fit this body perfectly, 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 BSE40X700S FAQ
The spring-applied collet clamps the rod instantly, providing a 900 N bidirectional static hold with no live air. It is a fail-safe hold, not a dynamic brake; the rod must be stopped before engagement.
Drive force at 0.5 MPa is 628 N push and 528 N pull. At 0.7 MPa, push is 879 N (90 kgf max drive). The separate static holding force of the lock is 900 N.
