Airtac BSE Clamp Standard Cylinder BSE80X350
The AirTAC Airtac BSE Clamp Standard Cylinder BSE80X350 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, 350mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE80X350
The AirTAC BSE80X350 is a double-acting, single-rod 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, ensuring suspended loads stay exactly where they stopped if air pressure drops. Operating pressure is capped at 0.7 MPa, and the cylinder runs at 30-800 mm/s.
This 80 mm bore unit uses a Ø25 mm piston rod with an M20x1.5 thread, a PT3/8 cylinder port, and a separate G1/8 release port. The lock engages a clamping collet mechanically, meaning the air cushion never acts as the holding device. This specific SKU lacks a magnet, so it does not support CMSE or DMSE position sensors.
Rod Lock — 3600 N Static Holding (Ø80mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE80X350 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 BSE80X350 Is Used
Vertical Pallet Lifts
Holds a 360 kg vertical pallet lift in place during E-stop or pressure loss, preventing drift while the drive supplies 3518 N push at 0.7 MPa.
Overhead Tooling Clamp
Keeps heavy machining tooling locked mid-cycle with 3600 N of fail-safe force, ensuring the 2513 N drive force does not drop unexpectedly on air exhaustion.
Pallet Stop Gate
Secures a raised pallet stop gate on an assembly conveyor, holding firm against impact with no live air while the cylinder cycles at 30-800 mm/s.
Is the Airtac BSE Clamp Standard Cylinder BSE80X350 the Right Cylinder?
Verify your load requires 3600 N or less of holding force. If you need less, the 63 mm bore offers 1402 N push at 0.5 MPa and 2200 N holding force. If you need more, the 100 mm bore provides 3927 N push at 0.5 MPa and 5500 N holding force. Always engage the lock only after the rod fully stops, and release it only when piston pressures are balanced, allowing at least 0.5 s before moving.
At 350 mm stroke, use guide rails to prevent side-load damage to the seals and collet. When replacing a unit, match the 80 mm bore, 350 mm stroke, PT3/8 port, and mounting style. SE-compatible mounting accessories fit this body perfectly, except FTC. The lock-release port remains G1/8 regardless of cylinder thread.
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 BSE80X350 FAQ
The spring-applied collet engages automatically, providing a 3600 N bidirectional static holding force to keep the rod fixed in both directions. It is a fail-safe lock, not a dynamic brake, so it must only engage after the rod has stopped moving.
The drive force is separate from the holding force. At 0.5 MPa, push is 2513 N and pull is 2268 N. At the 0.7 MPa ceiling, push is 3518 N, yielding a max drive of 359 kgf. The static holding force of the lock is 3600 N.
