About the Airtac BSAI Locking Clamp Cylinder BSAI32X300S
The AirTAC BSAI32X300-S is a double-acting ISO 15552 profile cylinder featuring a built-in spring-applied, air-released clamp-lock. It provides a static holding force of 600 N and can secure the piston rod at any position along its 300 mm travel. Because it includes a magnet for position sensing, it is fully compatible with AirTAC CMSE reed and DMSE solid-state switches. The base cylinder generates 402 N push and 345 N pull thrust at 0.5 MPa, with a practical maximum thrust of 563 N at 0.7 MPa.
It is crucial to understand that the 600 N static holding force is a separate metric from the cylinder's thrust; you must size the holding capacity against your static load, not the push force. The clamp mechanism uses a third G1/8 enclasp port and requires 0.15-0.7 MPa to unlock. Remember that the variable air cushion only decelerates the piston near stroke ends; the clamp is what actually 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 BSAI32X300S Is Used
Vertical Axis Hold
Secures a 32 mm bore vertical load at any point in its 300 mm stroke, preventing gravity drops during a power loss event.
Machining Position Lock
Clamps the carbon steel rod mid-stroke to hold a workpiece steady for machining or inspection without relying on live air.
Emergency Safety Hold
Acts as a fail-safe brake by engaging its 600 N clamp once the cylinder has stopped, ensuring loads do not shift unexpectedly.
Is the Airtac BSAI Locking Clamp Cylinder BSAI32X300S the Right Clamp-Lock?
Step down if your static load is minimal, or step up to a bore 40 unit if you need the 900 N holding force and 528 N pull thrust. Choose this BSAI clamp-lock over a SAIL model when you must hold the load somewhere in the middle of the stroke, because SAIL only locks at the end of travel. A plain SAI cylinder suffices if live air pressure constantly holds the load.
This model features a carbon steel rod with an M10x1.25 thread, PT tapered ports, and a 1/8 cylinder port. It accepts Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, and TCM2 mounts. Because the 300 mm stroke is relatively long for the 32 mm bore, an external guide is recommended to prevent rod side-load damage. The clamp locks only after the rod stops, so it cannot brake a moving load. Always balance air pressure on both sides before unlocking to prevent abrupt rod movement, and add independent safety measures for human-safety-critical holds.
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 BSAI32X300S FAQ
The built-in clamp-lock provides a static holding force of 600 N. It is bidirectional and locks at any position along the 300 mm stroke, but it only engages after the cylinder has stopped moving.
The clamp is spring-applied and air-released via a third G1/8 enclasp port. You must balance the air pressure on both sides of the piston before unlocking, otherwise the rod can jump abruptly.
