About the Airtac BSAI Locking Clamp Cylinder BSAI100X175S
The AirTAC BSAI100X175-S is a double-acting ISO 15552 profile cylinder equipped with a spring-applied, air-released clamp-lock. It delivers a robust 5497N of thrust at 0.7 MPa and features a magnet for position sensing. Crucially, its integrated enclasp mechanism provides a static holding force of 5500 N. Buyers must distinguish this holding force from thrust: the 5500 N rating dictates the static load capacity when parked, whereas thrust governs movement. The clamp locks the 25mm rod at any point along the 175mm travel.
This bidirectional lock engages only after the piston stops, meaning it cannot brake a moving load. To release the grip, air must be supplied to the dedicated G1/8 enclasp port, but only after pressures on both sides of the piston are balanced to prevent the rod from jumping abruptly. Remember that the adjustable air cushions merely decelerate the piston near stroke ends; the clamp itself is what secures the load.

How the Clamp-Lock Holds
static holding force (Ø100 mm)
A spring-applied gripper clamps the rod and holds the load at any position in the stroke — not just at the stroke end (that is a SAIL) — and it is bidirectional: it holds whether the rod was extending or retracting.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa (max) | 5498 N | — |
Push/pull as tabulated. Rated to the 0.7 MPa operating maximum for this series. The clamp holding force (5500 N) is separate from cylinder thrust. Size with a margin.
Where the Airtac BSAI Locking Clamp Cylinder BSAI100X175S Is Used
Vertical Axis Holding
Secures heavy elevated loads at any height along the 175mm stroke, preventing gravity-driven drops during a sudden air pressure loss.
Machining Position Lock
Freezes the 25mm rod firmly in place mid-travel to absorb machining vibration, ensuring workpiece stability without relying on live air pressure.
Emergency Safety Stop
Provides a reliable 5500 N clamp to hold a stopped load safely anywhere in the cycle if the pneumatic supply unexpectedly fails.
Is the Airtac BSAI Locking Clamp Cylinder BSAI100X175S the Right Clamp-Lock?
Select this 100mm bore when an application demands 5500 N of static holding capacity mid-stroke, rather than just end-of-stroke retention. If your load is lighter, stepping down to the 80mm bore offers 3600 N holding force and 3518N thrust at 0.7 MPa. Choose this BSAI over a SAIL model when you need the rod gripped at arbitrary positions, not just at the ends. If no intermediate holding is required, a plain SAI cylinder suffices. For safety-critical loads, add an independent external safety measure.
As a direct replacement, match the single-rod configuration, 100mm bore, 175mm stroke, and PT port threads. The cylinder ports are 1/2, and the enclasp port is G1/8. It accepts Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, or TCM2 mounts. The M20x1.5 rod thread and 25mm diameter handle high side loads well. The -S magnet works with AirTAC CMSE reed and DMSE solid-state sensors.
Quick checklist
- ✓ Hold needed at any position?
- ✓ Or stroke-end only → use SAIL
- ✓ Holding force ≥ your load
- ✓ Balanced-pressure unlock circuit

Airtac BSAI Locking Clamp Cylinder BSAI100X175S FAQ
It uses a spring-applied, air-released mechanism to grip the piston rod, providing a static holding force of 5500 N at any position along the 175mm stroke. It only engages after the cylinder stops and cannot brake a moving rod.
Before applying unlock pressure to the G1/8 enclasp port, the air pressures on both sides of the piston must be balanced. This prevents the rod from moving abruptly upon release, ensuring safe operation.
