About the Airtac BSAI Locking Clamp Cylinder BSAI32X700S
The AirTAC BSAI32X700-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 will secure the load at any position along its 700 mm travel. The base cylinder generates 402 N of thrust at 0.5 MPa, but remember that holding force and thrust are separate quantities: you must size the 600 N clamp capacity against your static load, not the cylinder push force.
This model includes a PT tapered port thread, a 12 mm carbon steel rod, and a -S magnet for CMSE reed and DMSE electronic sensors. The clamp mechanism uses a third G1/8 enclasp port and requires 0.15-0.7 MPa to unlock. Note that the variable air cushion only decelerates the piston near stroke ends; the clamp itself is what holds the load. Furthermore, the lock engages only after the rod has completely stopped, and it must be released with balanced pressures to prevent the rod from jumping abruptly.

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 BSAI32X700S Is Used
Vertical Axis Holding
Secures a 32 mm bore vertical load at any point in its 700 mm travel with 600 N of holding force, preventing drops when air pressure is removed.
Power Loss Emergency Stop
The spring-applied clamp engages automatically upon air loss to freeze the piston mid-stroke, providing a reliable fail-safe hold.
Machining Position Hold
Locks the rod rigidly after the cylinder has stopped, ensuring a vibration-free workpiece position for inspection or light machining.
Is the Airtac BSAI Locking Clamp Cylinder BSAI32X700S the Right Clamp-Lock?
Select this 32 mm bore model when you need an exact replacement for an ISO 15552 interchangeable cylinder with a 700 mm stroke and position-hold capability. Because 700 mm exceeds the standard 700 mm maximum for this bore, it is a non-standard stroke. If your application requires greater holding power, step up to the 40 mm bore, which offers 628 N thrust at 0.5 MPa and a 900 N holding force. Choose this BSAI over a SAIL model when you need to lock at any point in the travel, rather than just at the stroke end. If you only need standard movement without a hold, a plain SAI cylinder suffices.
For replacement, verify the single-rod configuration, 700 mm stroke, PT port threads, and the -S magnet option. The correct mounting set includes Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, and TCM2. Because the stroke is 700 mm, the 12 mm rod and M10x1.25 thread will still need an external guide to handle side loads over such a long unsupported distance. Always ensure the cylinder has stopped and pressures are balanced before unlocking to avoid sudden 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 BSAI32X700S FAQ
The clamp-lock provides a static holding force of 600 N. It is bidirectional and will hold the load at any position along the 700 mm stroke, provided the rod has already stopped moving.
The lock is spring-applied and air-released via a third G1/8 port. To unlock it safely, the cylinder must be stopped and the air pressures on both sides of the piston must be balanced; otherwise, the rod can jump. It cannot brake a moving rod.
