Airtac BSAI Locking Clamp Cylinder BSAI32X100
The AirTAC Airtac BSAI Locking Clamp Cylinder BSAI32X100 is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 100mm stroke and a spring-applied, air-released clamp-lock that holds the rod at ANY position along its travel — with a static holding force of 600 N.

About the Airtac BSAI Locking Clamp Cylinder BSAI32X100
The AirTAC BSAI32X100 is a double-acting ISO 15552 profile cylinder featuring a built-in clamp-lock mechanism. Unlike standard air cushions that only decelerate motion near the stroke ends, this spring-applied, air-released enclasp gripper physically clamps the 12mm piston rod to hold a static load of 600 N at any position along the 100mm travel. It provides a practical thrust of 402 N at 0.5 MPa (563 N at 0.7 MPa). A critical distinction is that this 600 N holding force is entirely separate from the cylinder thrust; you must size the clamp capacity against the static load, not the pneumatic push force.
The clamp operates via a dedicated G1/8 enclasp port, which is a third air connection independent of the two PT 1/8 cylinder drive ports. Because the lock engages only after the rod has completely stopped, it cannot function as a dynamic brake for a moving load. Furthermore, unlocking requires balanced air pressure on both sides of the piston to prevent the rod from jumping abruptly upon release.

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 BSAI32X100 Is Used
Vertical Axis Holding
Prevents gravity-driven drops on vertical actuators by clamping the rod securely at any intermediate height during an air pressure loss.
Machining Position Lock
Freezes the workpiece at a precise intermediate stroke location for drilling or inspection, ensuring the part remains totally immobile without relying on fluid pressure.
Emergency Mid-Stroke Stop
Provides a reliable physical hold wherever the rod stops during an emergency stop sequence, avoiding the drift that can occur if relying solely on closed valves.
Is the Airtac BSAI Locking Clamp Cylinder BSAI32X100 the Right Clamp-Lock?
Choose this 32mm bore model when an intermediate stop-and-hold is required anywhere in the 100mm stroke, whereas a SAIL variant only secures the load at the extreme stroke ends. If your application merely requires basic push/pull movement without mid-stroke holding, a plain SAI cylinder is sufficient. To increase capacity, stepping up to the 40mm bore raises the thrust to 628 N and the holding force to 900 N.
For replacements, match the single-rod configuration, 32x100 dimensions, and PT port threads. The mounting interface accepts Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, and TCM2 brackets. Note that the clamp locks only after the cylinder stops and releases safely only under balanced pressure; safety-critical applications require an independent mechanical backup. Position detection is possible by adding an -S magnet for AirTAC CMSE reed or DMSE solid-state sensors.
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 BSAI32X100 FAQ
The static holding force is 600 N. The clamp locks the rod only after it has completely stopped; it cannot brake a moving rod. If human safety depends on stopping the motion, an external independent brake is required.
It has two standard PT 1/8 cylinder drive ports and a third G1/8 enclasp/unlock port. To prevent the rod from jumping abruptly, the lock must only be released when the air pressures on both sides of the piston are balanced or the cylinder has stopped.
