About the Airtac BSAI Locking Clamp Cylinder BSAI32X160S
The AirTAC BSAI32X160-S is a double-acting ISO 15552 profile cylinder with a built-in spring-applied, air-released clamp-lock. It provides a static holding force of 600 N at any position along its 160 mm stroke. The 32 mm bore generates up to 563 N of thrust at 0.7 MPa. Remember that holding force and thrust are separate quantities; you must size the 600 N clamp capacity against your static load, not the 563 N cylinder thrust.
This unit includes a -S magnet for CMSE reed and DMSE solid-state sensors. The clamp requires a third G1/8 enclasp port to release, operating within a 0.15-0.7 MPa range. Note that the variable air cushion only decelerates the piston near stroke ends; the clamp mechanism is what actually secures the load.

How the Clamp-Lock Holds
static holding force (Ø32 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa (max) | 563 N | — |
Push/pull as tabulated. Rated to the 0.7 MPa operating maximum for this series. The clamp holding force (600 N) is separate from cylinder thrust. Size with a margin.
Where the Airtac BSAI Locking Clamp Cylinder BSAI32X160S Is Used
Vertical Axis Hold
Prevents gravity-driven drops on vertical lifts by clamping the 12 mm rod securely at any height, holding up to 600 N without live air pressure.
Power Loss Safety
Spring-applied clamp engages automatically during an air or power failure, freezing the load exactly where it stopped along the 160 mm travel.
Machining Position Lock
Secures a workpiece at a specific intermediate point for drilling or inspection, ensuring the rod does not shift under lateral machining forces.
Is the Airtac BSAI Locking Clamp Cylinder BSAI32X160S the Right Clamp-Lock?
Choose this 32 mm bore when you need a mid-stroke hold but only have a light load, as the 600 N clamp limit is lower than the 563 N cylinder thrust. If your static load exceeds 600 N, step up to the 40 mm bore, which offers a 900 N holding force and 628 N thrust at 0.5 MPa. Conversely, if you only need to hold at the stroke end, a plain SAIL32 suffices. The BSAI wins when the rod must stop and hold mid-travel.
This BSAI32X160-S has a 12 mm carbon steel rod with an M10x1.25 thread and PT tapered ports. It accepts Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, and TCM2 mounts. Because the clamp locks only after the rod stops and cannot brake a moving load, you must balance air pressures on both sides before unlocking to prevent the rod from jumping. For safety-critical applications, add an independent external measure.
Quick checklist
- ✓ Hold needed at any position?
- ✓ Or stroke-end only → use SAIL
- ✓ Holding force ≥ your load
- ✓ Balanced-pressure unlock circuit
- ✓ Extra safety measure for people
Airtac BSAI Locking Clamp Cylinder BSAI32X160S FAQ
The clamp-lock provides a static holding force of 600 N. It clamps the rod bidirectionally at any position along the 160 mm stroke, but it only engages after the cylinder has stopped moving.
The lock is air-released via a third G1/8 enclasp port. You must balance the air pressures on both sides of the piston before unlocking; otherwise, the rod can jump abruptly. The clamp cannot brake a moving rod, so safety-critical loads need an independent backup.
