Airtac BSE Clamp Standard Cylinder BSE80X75
The AirTAC Airtac BSE Clamp Standard Cylinder BSE80X75 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, 75mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE80X75
The AirTAC BSE80X75 is a double-acting single-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. The collet mechanism provides a 3600 N bidirectional fail-safe hold with no live air, securely preventing vertical loads from drifting if pressure drops. Operating pressure is capped at 0.7 MPa.
This 80 mm bore unit delivers a 0.7 MPa drive force of 3518 N, which is entirely separate from the 3600 N static holding force of the lock. The lock uses a dedicated G1/8 release port and requires 0.5 s to fully disengage before motion. This SKU has no magnet, so position sensing is not available.
Rod Lock — 3600 N Static Holding (Ø80mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE80X75 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 BSE80X75 Is Used
Vertical Lift Hold
Secures a 3500 N elevated machining head on a vertical slide, preventing a crash drop during an E-stop event.
Tool Clamp Lock
Maintains 3600 N of clamping force on a heavy stamping die when shop air is exhausted, ensuring the tool stays shut.
Pallet Stop Gate
Holds a 3000 N loaded pallet stationary at a conveyor inspection station using the fail-safe collet instead of live air.
Is the Airtac BSE Clamp Standard Cylinder BSE80X75 the Right Cylinder?
Verify your suspended load stays below the 3600 N static holding force. If you need less drive force, the 63 mm bore offers 1559 N push at 0.5 MPa and a 2200 N hold; if you need more, the 100 mm bore provides 3927 N push at 0.5 MPa and a 5500 N hold. Always engage the collet only after the piston stops, and release it solely when pressures are balanced.
For a direct replacement, match the 80 mm bore, 75 mm stroke, PT3/8 cylinder port, and your specific mounting choice. SE-compatible mounting accessories fit this body perfectly except for 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 BSE80X75 FAQ
The spring-applied collet engages automatically, providing a 3600 N bidirectional static hold with no live air. The drive forces are 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a max drive of 359 kgf.
You must supply 0.15-0.7 MPa to the separate G1/8 release port. Release the lock only after the rod has completely stopped and the pressures on both sides of the piston are balanced, allowing at least 0.5 s before moving.
