Airtac BSE Clamp Standard Cylinder BSE100X900S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE100X900S 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 5500 N in either direction — no drift. Ø100mm bore, 900mm stroke, PT1/2 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE100X900S
The AirTAC BSE100X900S is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A collet clamps the Ø25 mm piston rod, delivering a 5500 N bidirectional static holding force with no live air. Operating pressure is capped at 0.7 MPa, and the lock releases via a separate G1/8 port.
This fail-safe mechanism ensures the rod stays exactly where it stopped if air is exhausted or an E-stop trips. The lock is not a dynamic brake; engage it only after the rod stops, and release it only when piston pressures are balanced, allowing at least 0.5 s for full release. The -S magnet supports CMSE reed and DMSE electronic sensors.
Rod Lock — 5500 N Static Holding (Ø100mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE100X900S 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.

Specifications follow the official AirTAC BSE datasheet. The lock uses the SE standard body; SE mounting accessories fit BSE except FTC. Port options: PT (standard) / G (BSPP); lock-release port is G1/8.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa (max) | 5498 N | — |
| Max drive (@0.7 MPa) | 561 kgf | |
Drive force is separate from the 5500 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 BSE100X900S Is Used
Automated Press Tooling
Holds heavy press tooling in place mid-stroke. The 5500 N static hold prevents the 5497 N drive load from drifting down during air pressure loss.
Vertical Pallet Lift
Secures a raised pallet on a 900 mm vertical lift. The fail-safe collet locks instantly on E-stop, preventing suspended loads from crashing down.
Heavy Assembly Line Gate
Locks a large machine guard gate open during loading. The spring-applied collet holds the 100 mm bore rod firmly if plant air drops.
Is the Airtac BSE Clamp Standard Cylinder BSE100X900S the Right Cylinder?
Verify your suspended load is safely below the 5500 N holding force. If your drive requirement is lower, the 80 mm bore offers a 2513 N push at 0.5 MPa and a 3600 N hold. For heavier loads, the 125 mm bore provides 6136 N push at 0.5 MPa and an 8600 N hold. Always engage the lock only after the rod fully stops, and release it only when both sides are pressure-balanced.
This 900 mm stroke requires attention to side loads; use a guide rail to prevent piston binding. When replacing, match the 100 mm bore, 900 mm stroke, PT1/2 cylinder port, and -S magnet. SE mounting accessories fit this body perfectly, except FTC.
Quick checklist
- ✓ Load to hold ≤ 5500 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 BSE100X900S FAQ
It is spring-applied and fail-safe. If air is lost or exhausted, a collet clamps the rod, providing a 5500 N bidirectional static hold. It is not a dynamic brake; engage it only after the rod stops.
Drive force is 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa (max 561 kgf). This is separate from the 5500 N hold. To release, supply 0.15-0.7 MPa to the G1/8 port after balancing piston pressures, allowing 0.5 s.
