About the Airtac BSAI Locking Clamp Cylinder BSAI32X80
The AirTAC BSAI32X80 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, gripping the 12mm carbon steel rod to secure loads at any point along the 80mm travel. Operating at 0.15-0.7 MPa, it generates 563 N of thrust at maximum pressure. Remember that holding force and thrust are distinct metrics; size the 600 N clamp against your static load, not the cylinder's push force.
A third G1/8 enclasp port manages the unlock function, separate from the 1/8 PT cylinder ports. The lock engages only after the piston stops, serving as a hold device rather than a braking mechanism. For position feedback, add an -S magnet to use with CMSE reed or DMSE electronic sensors. The variable air cushion decelerates the piston near stroke ends, but the clamp itself is what 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 BSAI32X80 Is Used
Vertical Axis Holding
Prevents gravity-driven drops on vertical lifts by clamping the rod securely at any intermediate height during power loss.
Mid-Stroke Machining Hold
Locks the 80mm stroke firmly in place for light machining or assembly tasks without needing a mechanical stop.
Inspection Positioning
Holds a workpiece stationary at a defined inspection point, releasing only when air pressure is balanced.
Is the Airtac BSAI Locking Clamp Cylinder BSAI32X80 the Right Clamp-Lock?
Choose this 32mm bore when an application requires holding a load mid-stroke without relying on continuous air pressure. If the 600 N holding capacity is insufficient, stepping up to the BSAI40 bore increases the clamp force to 900 N and thrust to 879 N. If you only need to hold at the stroke ends, a plain SAIL end-lock suffices. For simple movement without holding, a standard SAI cylinder is adequate.
Replacement requires a single-rod, 32mm bore, 80mm stroke with PT ports. Mounting options include Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, and TCM2. The clamp locks after the rod stops and must be released with balanced pressures to prevent sudden rod jumps. For human-safety critical applications, add an independent mechanical safety measure. The 12mm rod with an M10x1.25 thread handles moderate side loads well.
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 BSAI32X80 FAQ
The BSAI32X80 provides a static holding force of 600 N. This bidirectional clamp locks at any position along the stroke, but only after the cylinder has stopped moving.
The clamp is released via a third G1/8 port, but only when the air pressures on both sides of the piston are balanced. Releasing without balanced pressure can cause the rod to jump abruptly.
