Airtac BSE Clamp Standard Cylinder BSE100X300S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE100X300S 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, 300mm stroke, PT1/2 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE100X300S
The AirTAC BSE100X300S 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 zero live air required to maintain the hold. Operating pressure is capped at 0.7 MPa, and unlocking requires 0.15-0.7 MPa supplied to the separate G1/8 release port.
This fail-safe mechanism ensures that if air is exhausted or an E-stop trips, the rod is held securely in both directions at its stopped position. The lock is a static holding device, not a dynamic brake; it must only be engaged after the rod stops moving, and released only when piston pressures are balanced. The -S magnet option allows for precise position sensing with CMSE reed or 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 BSE100X300S 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 (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 BSE100X300S Is Used
Heavy Vertical Lift Holding
Secures a 500 kg vertical machining axis instantly on air loss, preventing a crash while staying well under the 5500 N holding limit.
Multi-Spindle Drill Head
Locks a heavy drill head in its retracted position during E-stop, using the 5500 N collet to hold against the 5497 N drive force.
Pallet Stopper Gate
Holds a raised pallet stop gate fixed mid-stroke during maintenance; the spring-applied collet prevents any drift without live air.
Is the Airtac BSE Clamp Standard Cylinder BSE100X300S the Right Cylinder?
Verify your load does not exceed the 5500 N static holding force. If you need less force, stepping down to the 80 mm bore gives a 0.5 MPa push of 2513 N and a 3600 N hold. If you need more, the 125 mm bore yields a 6136 N push at 0.5 MPa and an 8600 N hold. For this 300 mm stroke, add external guide rails to prevent side-load wear on the seals and lock collet.
When replacing, match the 100 mm bore, 300 mm stroke, PT1/2 cylinder port, and the -S magnet. The lock-release port is always G1/8. SE mounting accessories fit this ISO 15552 body perfectly except for FTC. Always allow at least 0.5 s after balancing pressures before releasing the lock to move.
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 BSE100X300S FAQ
The drive force is 3927 N push and 3681 N pull at 0.5 MPa, or 5497 N push at 0.7 MPa (max 561 kgf). The static holding force of the spring-applied rod lock is 5500 N, which is entirely separate from the drive force.
The lock is fail-safe: a spring applies the clamping collet automatically, holding the load bidirectionally at whatever position it stopped. To release it, you must supply 0.15-0.7 MPa to the G1/8 release port after balancing piston pressures, allowing at least 0.5 s before moving.
