About the Airtac BSAI Locking Clamp Cylinder BSAI32X350S
The AirTAC BSAI32X350-S is a double-acting ISO 15552 profile cylinder with a built-in clamp-lock mechanism. A spring-applied, air-released gripper clamps the 12 mm carbon steel rod to hold the load at any position along its 350 mm stroke, delivering a static holding force of 600 N. The -S magnet enables position detection via AirTAC CMSE (reed) and DMSE (electronic) switches. Operating pressure is 0.15-0.7 MPa, yielding a practical maximum thrust of 563 N.
It is critical to distinguish this 600 N holding force from the cylinder thrust; the clamp sustains a static load, while thrust drives the motion. The clamp operates via a third G1/8 enclasp port, separate from the PT 1/8 cylinder ports. Remember that the variable air cushion only decelerates the piston near stroke ends; the clamp is the sole device that holds 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 BSAI32X350S Is Used
Vertical Axis Drop Prevention
Holds a lifted payload securely at any point in the 350 mm travel during an air pressure loss, preventing gravity-driven falls.
Mid-Stroke Machining Hold
Locks the rod at a specific intermediate position to rigidly support a workpiece during drilling or assembly operations.
Emergency Safety Stop
Maintains the cylinder's position anywhere along the stroke when the system e-stops, ensuring the load remains fixed until pressure is restored.
Is the Airtac BSAI Locking Clamp Cylinder BSAI32X350S the Right Clamp-Lock?
Choose this 32 mm bore when an application requires mid-stroke holding that a plain SAI or stroke-end-only SAIL cannot provide. If higher load capacity is needed, stepping up to a 40 mm bore increases thrust to 628 N and holding force to 900 N. Conversely, if the 600 N hold is excessive for a lighter payload, a smaller bore would be required, though 32 mm is the smallest available.
This clamp locks only after the rod has completely stopped; it cannot brake a moving load. Unlocking requires balanced air pressure on both sides of the piston, or the rod may jump abruptly. For safety-critical applications, an independent external safety measure is mandatory. As a direct replacement, match the single-rod configuration, 350 mm stroke, PT ports, and the BSAI mounting set (Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, TCM2). Because the stroke is 350 mm, the M10x1.25 rod should use external guidance to prevent excessive side-loading.
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 BSAI32X350S FAQ
The clamp-lock provides a static holding force of 600 N. It engages a spring-applied gripper on the rod to hold the load at any position along the stroke, functioning bidirectionally.
The clamp unlocks only when air pressure is balanced on both sides of the piston via the G1/8 enclasp port. If pressures are not balanced, the rod can move abruptly. The lock engages only after the rod stops and cannot brake a moving load.
