Airtac BSE Clamp Standard Cylinder BSE80X350S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE80X350S 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 BSE80X350S
The AirTAC BSE80X350S 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 required. This fail-safe mechanism ensures suspended or vertical loads remain exactly where they stopped if air pressure drops or an E-stop is triggered.
Operating pressure is capped at 0.15-0.7 MPa, and the lock unlocks via a separate G1/8 port. The drive force is entirely separate from the holding force; at 0.7 MPa, this 80 mm bore generates a 3518 N push. The -S magnet supports CMSE reed and DMSE electronic sensors for position feedback. SE mounting accessories fit this body perfectly, except for FTC.
Rod Lock — 3600 N Static Holding (Ø80mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE80X350S 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 BSE80X350S Is Used
Vertical Lift Hold
Holds a 350 kg vertical lift assembly mid-stroke. The 3600 N collet lock engages instantly on air loss, preventing a crash while the 3518 N drive handles the lifting cycle.
Tooling Clamp Drift
Secures heavy machining clamps during an E-stop. The spring-applied lock maintains position without live air, keeping the 359 kgf drive force ready when released.
Pallet Stop Gate
Blocks pallets on an overhead conveyor. The fail-safe collet holds the stop pin against impact with no air pressure, unlocking smoothly via the G1/8 port.
Is the Airtac BSE Clamp Standard Cylinder BSE80X350S the Right Cylinder?
Verify your load to hold is at or below the 3600 N static holding force. If you need less drive, step down to the 63 mm bore (1559 N push @0.5 MPa, 2200 N hold). If you need more holding capacity, step up to the 100 mm bore (3927 N push @0.5 MPa, 5500 N hold). Always engage the lock only after the rod has completely stopped, and release it only when pressures on both piston sides are balanced, allowing at least 0.5 s before moving.
At 350 mm stroke, the extended rod is susceptible to side-loads; use a guide to prevent binding. Confirm your replacement matches the 80 mm bore, 350 mm stroke, PT3/8 cylinder port, and the -S magnet option. The lock-release port is always G1/8.
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 BSE80X350S 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 static holding force of the rod lock is 3600 N, which is completely separate from the drive force.
The lock is spring-applied and fail-safe. If air is lost, exhausted, or an E-stop trips, the collet clamps the rod and holds the load bidirectionally up to 3600 N. To release, supply 0.15-0.7 MPa to the G1/8 port after balancing piston pressures, allowing 0.5 s.
