About the Airtac BSAI Locking Clamp Cylinder BSAI32X300
The AirTAC BSAI32X300 is a double-acting ISO 15552 profile cylinder equipped with a built-in clamp-lock mechanism. It uses a spring-applied, air-released gripper to secure the piston rod at any position along its 300mm travel, delivering a static holding force of 600 N. The cylinder itself generates 402 N of push thrust at 0.5 MPa, but the holding force is a separate mechanical quantity—you must size the clamp's 600 N rating against your static load, not the pneumatic thrust.
This enclasp unit operates on a 0.15-0.7 MPa pressure range and requires a third G1/8 unlock port alongside the 1/8 cylinder ports. The variable air cushions at both ends only decelerate the piston near stroke end; the mechanical clamp is what actually holds the load. Because it is a profile cylinder with an extruded aluminum barrel, it is dimensionally interchangeable per ISO 15552 without using tie-rods.

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 BSAI32X300 Is Used
Vertical Axis Hold
Secures a 32mm bore vertical lift at any intermediate height with 600 N of holding force, preventing drops when air pressure is removed.
Emergency Stop Safety
Maintains a clamped position anywhere along the 300mm stroke during a sudden power loss, though an independent measure is needed for human safety.
Machining Position Lock
Freezes the rod at a specific intermediate length for a machining or inspection process, ensuring the workpiece remains entirely stationary.
Is the Airtac BSAI Locking Clamp Cylinder BSAI32X300 the Right Clamp-Lock?
Choose this 32mm bore if your application requires holding a mid-stroke load of up to 600 N without maintaining live air pressure. If you only need to secure the load at the fully extended or retracted stroke end, a SAIL cylinder is sufficient; BSAI is necessary when you must lock at any intermediate position. If your load exceeds 600 N, step up to the 40mm bore, which provides 628 N of thrust at 0.5 MPa and a 900 N holding force.
For replacement, match the single-rod configuration, 32mm bore, 300mm stroke, and PT threaded ports. It accepts Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, and TCM2 mounts. Note that this 300mm stroke is relatively long for a 12mm rod, so external guidance is recommended to prevent excessive side-loading. The clamp locks only after the rod has stopped and cannot brake a moving load; it must be unlocked with balanced pressures to prevent the rod from jumping. Safety-critical applications require an independent external safety 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 BSAI32X300 FAQ
The BSAI32X300 provides a static holding force of 600 N. The clamp is bidirectional and can secure the rod at any position along the stroke, but it only engages after the cylinder has stopped moving.
The clamp is spring-applied and air-released via a separate G1/8 port. You must balance the air pressures on both sides of the piston before unlocking, otherwise the rod may move abruptly. It cannot be used to brake a moving rod.
