Airtac BSE Clamp Standard Cylinder BSE80X450S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE80X450S 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 BSE80X450S
The AirTAC BSE80X450S is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It delivers a 3600 N bidirectional static holding force, ensuring suspended loads remain safely frozen in place if air pressure drops or an E-stop is hit. Operating pressure is capped at 0.7 MPa, and the lock utilizes a separate G1/8 release port.
This 80 mm bore, 450 mm stroke unit features a 25 mm rod and adjustable air cushions at both ends. The integrated collet lock is a holding device, not a dynamic brake; it must only engage after the rod fully stops. The -S magnet option supports CMSE reed and DMSE electronic sensors for precise position tracking.
Rod Lock — 3600 N Static Holding (Ø80mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE80X450S 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 (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 BSE80X450S Is Used
Injection Mold Platens
Holds heavy mold platens mid-stroke. The 3600 N collet lock prevents sudden drops if factory air supply drops, while the 2513 N drive force moves the tooling.
Palletizer Lift Arms
Secures vertical lift arms carrying pallets. The fail-safe spring-applied lock engages instantly on E-stop, preventing gravity-driven falls without live air.
Heavy Duty Diverter Gates
Locks large package diverter gates in the extended position. The bidirectional hold ensures the gate stays put against impacting cartons during line jams.
Is the Airtac BSE Clamp Standard Cylinder BSE80X450S the Right Cylinder?
Verify your load requires a holding force at or below 3600 N. If you need less holding or drive force, the adjacent 63 mm bore offers 1559 N push at 0.5 MPa and a 2200 N hold. If your load is higher, stepping up to the 100 mm bore provides 3927 N push at 0.5 MPa and a 5500 N hold. The drive force for this 80 mm bore is 2513 N push and 2268 N pull at 0.5 MPa.
At 450 mm stroke, use guide rails to prevent side-load wear on the seals. To replace this unit, match the 80 mm bore, 450 mm stroke, PT3/8 port, and -S magnet. SE mounting accessories fit this body directly, except FTC brackets. Always balance pressures on both sides of the piston and allow at least 0.5 s for full lock release before moving.
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 BSE80X450S FAQ
The drive force is 2513 N push and 2268 N pull at 0.5 MPa, and 3518 N push at 0.7 MPa (max 359 kgf). The separate static holding force of the rod lock is 3600 N, which holds the load with no live air.
A spring applies a clamping collet to the rod, so air loss instantly engages the 3600 N bidirectional hold. To release, supply 0.15-0.7 MPa to the G1/8 release port, ensure both piston sides are pressure-balanced, and wait at least 0.5 s before moving.
