Airtac BSE Clamp Standard Cylinder BSE80X400S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE80X400S 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 Ø25mm rod and holds up to 3600 N in either direction — no drift. Ø80mm bore, 400mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE80X400S
The AirTAC BSE80X400S is a double-acting, single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. It delivers a 3518 N push force at 0.7 MPa while providing a robust 3600 N bidirectional static holding force that secures your load the moment air is exhausted or E-stop trips.
This fail-safe collet mechanism operates via a separate G1/8 release port, completely distinct from the adjustable air cushions at both ends. Equipped with an -S magnet, it supports CMSE reed and DMSE electronic sensors for precise position feedback across the 400 mm stroke.
Rod Lock — 3600 N Static Holding (Ø80mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE80X400S 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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa (max) | 3519 N | — |
| Max drive (@0.7 MPa) | 359 kgf | |
Drive force is separate from the 3600 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 BSE80X400S Is Used
Vertical Palletizer
Holds a lifted pallet handler securely mid-stroke with 3600 N of fail-safe force, preventing a catastrophic drop if the 0.7 MPa air supply is lost.
Injection Mold Tooling
Clamps heavy mold bases in place during air exhaustion, utilizing the 3518 N drive to shift tooling and the collet lock to maintain exact positioning.
Heavy Pallet Stop Gate
Acts as a rigid barrier on a packaging line, using its bidirectional hold to keep the gate locked firm against heavy payload impacts during E-stop events.
Is the Airtac BSE Clamp Standard Cylinder BSE80X400S the Right Cylinder?
Verify your suspended load requires less than the 3600 N static holding force. If your drive force needs are lower, the 63 mm bore offers a 1559 N push at 0.5 MPa and a 2200 N hold; if you need more stopping power, the 100 mm bore provides a 3927 N push at 0.5 MPa and a 5500 N hold.
Always engage the lock only after the 25 mm rod fully stops, and release it only when piston pressures are balanced, allowing at least 0.5 s before moving. For this 400 mm stroke, use a guide to prevent side-load wear. Replacement requires matching the 80 mm bore, 400 mm stroke, PT3/8 port, and -S magnet. SE mounting accessories fit perfectly except FTC.
Quick checklist
- ✓ Load to hold ≤ 3600 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 BSE80X400S FAQ
The spring-applied collet instantly clamps the rod, providing a 3600 N bidirectional static holding force with no live air. It is a fail-safe hold, not a dynamic brake; the rod must be stopped before engagement.
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At the 0.7 MPa ceiling, push is 3518 N (max 359 kgf). This drive force is separate from the 3600 N static holding force.
