Airtac BSE Clamp Standard Cylinder BSE80X450
The AirTAC Airtac BSE Clamp Standard Cylinder BSE80X450 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, 450mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE80X450
The AirTAC BSE80X450 is a double-acting, single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A collet clamps the Ø25 mm piston rod automatically, delivering a 3600 N bidirectional static holding force with zero live air. This fail-safe mechanism prevents drift or drops if supply pressure is exhausted or an E-stop trips.
Operating pressure is capped at 0.15-0.7 MPa, and the lock unlocks via a separate G1/8 port. The lock is a holding device, not a dynamic brake: engage it only after the rod fully stops, and allow at least 0.5 s for release after balancing piston pressures. This 80 mm bore, 450 mm stroke variant lacks a magnet (-S) for position sensing.
Rod Lock — 3600 N Static Holding (Ø80mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE80X450 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.

Where the Airtac BSE Clamp Standard Cylinder BSE80X450 Is Used
Vertical Pneumatic Lift
Holds a 360 kg vertical lift load firmly in place during an E-stop or pressure loss, preventing sudden drops using the 3600 N static collet hold.
Pallet Stopper Gate
Acts as a mid-stroke stop on a conveyor line. The fail-safe lock keeps the gate extended securely even if the main air supply is exhausted.
Machine Tool Clamp
Maintains workpiece clamping force on a machining center during air pressure dips, ensuring the part stays fixed without relying on live air.
Is the Airtac BSE Clamp Standard Cylinder BSE80X450 the Right Cylinder?
Verify your load to hold does not exceed the 3600 N static figure. For sizing context, the adjacent BSE63 bore offers 1559 N push at 0.5 MPa and 2200 N hold, while the larger BSE100 provides 3927 N push at 0.5 MPa and 5500 N hold. Step up if your suspended mass or dynamic forces exceed the 80 mm limits.
Because the stroke is 450 mm, use a guide to prevent side-load wear on the seals and barrel. To release safely, balance pressures across the piston before supplying air to the G1/8 release port. When replacing, match the 80 mm bore, 450 mm stroke, PT3/8 cylinder port, and mounting. SE mounting accessories fit this body 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 BSE80X450 FAQ
The spring-applied collet instantly clamps the rod, providing a 3600 N bidirectional static holding force to prevent movement. It is a fail-safe hold, not a dynamic brake; the rod must be stopped before engagement. Supply 0.15-0.7 MPa to the G1/8 release port to unlock it.
At 0.5 MPa, the drive force is 2513 N push and 2268 N pull. At the 0.7 MPa maximum, push is 3518 N, yielding a max drive of 359 kgf. This drive force is separate from the 3600 N static holding force of the lock.
