Airtac BSE Clamp Standard Cylinder BSE80X900S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE80X900S 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 BSE80X900S
The AirTAC BSE80X900S is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It delivers a 3600 N bidirectional static holding force, ensuring suspended loads stay fixed the moment air pressure drops or an E-stop trips. Operating pressure is capped at 0.7 MPa, and the lock uses a dedicated G1/8 release port.
This 80 mm bore, 900 mm stroke unit features a magnetic piston (-S) for use with CMSE reed or DMSE electronic sensors. The drive force is entirely separate from the lock, providing 2513 N push at 0.5 MPa. The collet lock engages only after the piston stops, requiring balanced pressure and a 0.5 s delay before motion resumes.
Rod Lock — 3600 N Static Holding (Ø80mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE80X900S 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 BSE80X900S Is Used
Vertical Lift Hold
Secures a 350 kg vertical machining axis in place during a sudden air loss, relying on the 3600 N fail-safe collet lock to prevent a crash.
Overhead Tool Clamp
Maintains grip on suspended injection molding tooling. The spring-applied lock keeps the 2513 N drive load fixed if the main supply exhausts.
Pallet Stop Gate
Holds a heavy pallet stop firmly during an E-stop event. The lock holds the load with no live air, while the DMSE sensor tracks position.
Is the Airtac BSE Clamp Standard Cylinder BSE80X900S the Right Cylinder?
Verify your load requires 3600 N or less of holding force. If you need less, step down to the 63 mm bore (1559 N push @0.5 MPa, 2200 N hold). If your load exceeds 3600 N, step up to the 100 mm bore (3927 N push @0.5 MPa, 5500 N hold). Always engage the lock only after the rod fully stops, and release it only when piston pressures are balanced.
With a 900 mm stroke, use external guide rails to prevent side-loading damage to the seal and rod. To match this cylinder for replacement, confirm the PT3/8 port, M20x1.5 rod thread, and SE-compatible mounting (excluding 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 BSE80X900S FAQ
The integrated rod lock is spring-applied and fail-safe. If air is lost or exhausted, the collet clamps the rod and provides a 3600 N bidirectional static holding force, keeping the load fixed in place.
The drive forces are 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 lock is 3600 N.
