Airtac BSE Clamp Standard Cylinder BSE80X50S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE80X50S 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, 50mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE80X50S
The AirTAC BSE80X50S is a double-acting single-rod ISO 15552 profile cylinder featuring a spring-applied, air-released rod lock. It delivers a 3600 N bidirectional static holding force with no live air, clamping the Ø25 mm piston rod via collet whenever pressure drops or an E-stop trips. Operating pressure is capped at 0.7 MPa.
This 80 mm bore unit runs at 30-800 mm/s with adjustable air cushions at both ends. The -S option includes a magnet for CMSE reed and DMSE electronic sensors. A separate G1/8 release port unlocks the collet, requiring at least 0.5 s and balanced piston pressures before movement.
Rod Lock — 3600 N Static Holding (Ø80mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE80X50S 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 BSE80X50S Is Used
Vertical Pallet Lift
Secures a 300 kg vertical pallet lift in place during air loss, utilizing the 3600 N fail-safe holding force to prevent uncontrolled drops.
Pallet Transfer Stop
Acts as a rigid stop gate on a conveyor. The spring-applied collet holds firmly against 2513 N of push force at 0.5 MPa if shop air is exhausted.
Vertical Drill Head
Locks a heavy vertical drill head in its retracted position during an E-stop, keeping the 3518 N drive force safely suspended without live air.
Is the Airtac BSE Clamp Standard Cylinder BSE80X50S the Right Cylinder?
Verify your suspended load stays under the 3600 N holding force. If your load is lighter, the 63 mm bore offers 1559 N push at 0.5 MPa and 2200 N hold. If you need more stopping power, the 100 mm bore provides 3927 N push at 0.5 MPa and 5500 N hold. To replace this unit, match the 80 mm bore, 50 mm stroke, PT3/8 port, and -S magnet.
Because the stroke is 50 mm, side-load risks are minimal, but always guide the load. Engage the lock only after the rod fully stops, and release it only when pressures are balanced. SE mounting accessories fit this body except 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 BSE80X50S FAQ
The drive force is 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, with a max drive of 359 kgf. The separate static holding force of the rod lock is 3600 N.
A spring applies a clamping collet to the rod, providing a 3600 N bidirectional fail-safe hold. To release it, supply air to the G1/8 port, ensure both piston sides are balanced, and wait at least 0.5 s before moving.
