Airtac BSE Clamp Standard Cylinder BSE80X300S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE80X300S 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, 300mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE80X300S
The AirTAC BSE80X300S 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 with no live air required, ensuring suspended loads stay fixed during pressure loss or E-stops. Operating pressure is capped at 0.7 MPa.
This model features a 25 mm rod, M20x1.5 thread, and PT3/8 cylinder ports, alongside a dedicated G1/8 lock-release port. The -S magnet supports CMSE reed and DMSE electronic sensors for exact position tracking. Engage the collet only after the rod fully stops, and allow at least 0.5 s for release after balancing piston pressures.
Rod Lock — 3600 N Static Holding (Ø80mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE80X300S 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 BSE80X300S Is Used
Overhead Crane Stops
Holds a 360 kg suspended crane hook assembly safely in both directions during air loss, preventing drift while moving heavy structural steel.
CNC Tool Change
Locks a machining center tool carousel at the exact change position with 3600 N of force, ensuring no drop or misalignment if air supply fails.
Pallet Diverter
Secures a vertical diverter gate mid-stroke during E-stop events, using the 3518 N drive force to move the 25 mm rod and 3600 N to hold it rigid.
Is the Airtac BSE Clamp Standard Cylinder BSE80X300S the Right Cylinder?
Verify your load stays under the 3600 N static holding capacity. If your application needs less drive force, the 63 mm bore offers 1559 N push at 0.5 MPa and a 2200 N hold. For heavier demands, the 100 mm bore provides 3927 N push at 0.5 MPa and a 5500 N hold. SE mounting accessories fit this body perfectly except FTC.
With a 300 mm stroke, use guide rails to prevent side-load damage to the 25 mm rod. Remember the lock is a holding device, not a dynamic brake; engage it only after motion stops, and release it only when pressures are balanced.
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 BSE80X300S FAQ
At 0.5 MPa, push force is 2513 N and pull is 2268 N. At 0.7 MPa, push is 3518 N (max 359 kgf drive). The separate static holding force of the rod lock is 3600 N.
The lock is spring-applied and fail-safe. If air is lost, the collet immediately clamps the rod, providing 3600 N of bidirectional holding force. To release, apply 0.15-0.7 MPa to the G1/8 port after balancing piston pressures, waiting at least 0.5 s.
