About the Airtac BSAI Locking Clamp Cylinder BSAI32X700
The AirTAC BSAI32X700 is a double-acting ISO 15552 profile cylinder equipped with a spring-applied, air-released clamp-lock mechanism. A defining feature of this series is its ability to lock the piston rod at any position along its 700mm travel, providing a documented static holding force of 600 N. At 0.7 MPa, the cylinder generates 563 N of practical thrust, but buyers must distinguish between thrust and holding force: the 600 N clamp rating dictates the static load capacity, not the pneumatic push force.
This enclasp mechanism is bidirectional, securing the load whether the rod was extending or retracting. The clamp engages via a dedicated G1/8 enclasp port and requires 0.15-0.7 MPa to unlock. It is critical to note the clamp locks only after the rod stops; it cannot brake a moving load. Furthermore, the variable air cushion merely decelerates the piston near stroke ends and does not contribute to holding 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 BSAI32X700 Is Used
Vertical Axis Hold
Maintains a 600 N static hold on a vertical load at any point in the 700mm travel, preventing gravity-driven drops during air pressure loss.
Emergency Power-Off Hold
Spring-applied clamp secures the rod instantly when the system stops, locking the payload safely mid-cycle until air pressure is restored.
Machining Position Lock
Freezes the rod at a precise coordinate for secondary machining or inspection, ensuring the workpiece remains completely stationary.
Is the Airtac BSAI Locking Clamp Cylinder BSAI32X700 the Right Clamp-Lock?
Choose this 32mm bore model when an application demands position holding mid-stroke, a capability where BSAI surpasses the SAIL series which only locks at stroke ends. If live pressure drops are not a concern, a plain SAI cylinder suffices. For heavier loads, stepping up to the 40mm bore offers 628 N thrust at 0.5 MPa and a 900 N holding force. Because the 700mm stroke exceeds the standard 700mm maximum for this bore, it is a non-standard stroke; the 12mm rod and M10x1.25 thread carry side loads well, but an external guide is recommended for this long travel.
To replace this unit, match the single-rod configuration, 32mm bore, 700mm stroke, and PT port threads. It supports Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, and TCM2 mounts. Without a magnet (-S), it cannot host CMSE or DMSE sensors. Always unlock the clamp with balanced air pressures on both sides of the piston to prevent the rod from jumping abruptly, 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 BSAI32X700 FAQ
The clamp-lock provides a static holding force of 600 N. It can secure the rod at any position along the 700mm stroke, but it only engages after the cylinder has stopped moving and cannot act as a brake for a moving rod.
The clamp is released by supplying air to the G1/8 enclasp port. To prevent the rod from jumping abruptly, the air pressures on both sides of the piston must be balanced before unlocking, ensuring the cylinder has stopped.
