Airtac BSE Clamp Standard Cylinder BSE80X900
The AirTAC Airtac BSE Clamp Standard Cylinder BSE80X900 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, 900mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE80X900
The AirTAC BSE80X900 is a double-acting ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A collet clamps the 25 mm rod to deliver a 3600 N bidirectional static holding force. This fail-safe mechanism holds the load securely in both directions whenever air is lost or exhausted. Operating pressure is capped at 0.7 MPa.
The lock uses a separate G1/8 release port to overcome the spring and free the rod. Because this unit lacks the -S magnet option, it does not support CMSE or DMSE position sensors. You can reuse standard SE mounting accessories for this 80 mm bore, except for FTC brackets. The 900 mm stroke operates at speeds of 30-800 mm/s with 36 mm adjustable air cushions at both ends.
Rod Lock — 3600 N Static Holding (Ø80mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE80X900 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 BSE80X900 Is Used
Vertical Lift Hold
Maintains a 3600 N static hold on vertical lifting stages if air pressure drops, preventing gravity-driven falls without needing live air.
Overhead Tool Clamp
Secures suspended machining heads in place during an E-stop event, locking the 25 mm rod instantly to protect operators and parts.
Pallet Stop Gate
Holds a raised pneumatic stop gate firmly on a packaging conveyor line, ensuring the collet lock keeps the barrier rigid even under impact.
Is the Airtac BSE Clamp Standard Cylinder BSE80X900 the Right Cylinder?
Verify your suspended load does not exceed the 3600 N 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. At 0.7 MPa, this 80 mm bore generates 3518 N push (359 kgf max drive).
Engage the lock only after the rod completely stops, and release it only when piston pressures are balanced, allowing at least 0.5 s for full release before moving. For the 900 mm stroke, use a guide to prevent side-loading damage to the seals. When replacing, match the 80 mm bore, 900 mm stroke, PT3/8 port, and basic mounting.
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 BSE80X900 FAQ
The drive force at 0.5 MPa is 2513 N push and 2268 N pull. At 0.7 MPa, push is 3518 N (max 359 kgf). The static holding force of the rod lock is 3600 N. Drive force moves the load; the holding force keeps it stationary.
The collet lock is spring-applied and air-released. If air is lost or exhausted, the lock engages automatically to provide a 3600 N bidirectional hold. To release safely, balance piston pressures and apply air to the G1/8 release port for at least 0.5 s before moving.
