Airtac BSE Clamp Standard Cylinder BSE40X450S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE40X450S 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, 450mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE40X450S
The AirTAC BSE40X450S 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, delivering a bidirectional 900 N static holding force with no live air. Operating pressure is capped at 0.15-0.7 MPa.
The lock engages only after the rod stops, requiring balanced piston pressures and at least 0.5 s for release. A separate G1/8 port unlocks the unit, while the main cylinder uses a PT1/4 port. 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 BSE40X450S 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 BSE40X450S Is Used
Vertical Lift Doors
Holds a 900 N suspended industrial door instantly in place during an E-stop or pressure loss, preventing gravity drift.
Tooling Clamp
Secures a 628 N clamping fixture on a machining center; the fail-safe collet prevents the tool from dropping when air is exhausted.
Pallet Stopper Gate
Locks a 16 mm rod in an assembly line conveyor stop. The 900 N hold keeps the gate rigid even if the main air supply is cut.
Is the Airtac BSE Clamp Standard Cylinder BSE40X450S the Right Cylinder?
Verify your load does not exceed the 900 N holding force. If you need less drive, the 32 mm bore offers 402 N push at 0.5 MPa and a 600 N hold. For heavier loads, the 50 mm bore provides 982 N push at 0.5 MPa and a 1400 N hold. Ensure pressures are balanced before unlocking.
At 450 mm stroke, use a guide to prevent side-loading damage. SE mounting accessories fit this body except FTC. When replacing, match the 40 mm bore, 450 mm stroke, PT thread, basic mounting, and -S magnet.
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 BSE40X450S 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 lock, not a dynamic brake, so engage it only after the rod has completely stopped.
Drive force is 628 N push at 0.5 MPa, 528 N pull at 0.5 MPa, 879 N push at 0.7 MPa, and max 90 kgf drive at 0.7 MPa. The separate static holding force of the lock is 900 N.
