Airtac BSAI Locking Clamp Cylinder BSAI32X225
The AirTAC Airtac BSAI Locking Clamp Cylinder BSAI32X225 is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 225mm 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 BSAI32X225
The AirTAC BSAI32X225 is a double-acting ISO 15552 profile cylinder featuring a built-in spring-applied, air-released clamp-lock. It secures the load at any position along its 225mm stroke, delivering a static holding force of 600 N. The base extruded-aluminum barrel operates at 0.15-0.7 MPa, generating 402 N of push thrust at 0.5 MPa. Remember that holding force and thrust are separate quantities; you must size the 600 N clamp against your static load, not the cylinder's horizontal push power.
This enclasp mechanism is bidirectional and locks only after the piston has completely stopped, meaning it cannot brake a moving rod. The clamp operates via a dedicated G1/8 third port, entirely separate from the 1/8 cylinder ports. Crucially, the variable air cushion at the ends only decelerates the piston near stroke limits; it does not hold the load. The clamp must be released with balanced air 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 BSAI32X225 Is Used
Vertical Lift Holding
Prevents gravity-driven drops on vertical axes by clamping the rod at any height, sustaining the load safely during air pressure loss.
Machining Position Lock
Freezes the rod at a specific intermediate travel point for secure workpiece machining or inspection without full retraction.
Emergency Power Fail-Safe
Engages instantly upon air loss to freeze the mechanism in place mid-cycle, preventing uncontrolled movements.
Is the Airtac BSAI Locking Clamp Cylinder BSAI32X225 the Right Clamp-Lock?
Step down if your payload is minimal, but stepping up to a 40 mm bore raises the holding capacity to 900 N and thrust to 628 N. Choose this BSAI over a SAIL model when you need to halt and hold mid-stroke, rather than just at the end. A plain SAI suffices if no position holding is required. This single-rod unit features an M10x1.25 thread and PT ports. It accepts Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, or TCM2 mounts. Because the rod is 12 mm, long unsupported strokes still need an external guide to manage side loads.
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 BSAI32X225 FAQ
The 600 N static holding force is the clamp's grip on the rod, entirely separate from the 402 N push thrust. You must size the 600 N clamp against your static load weight, not the cylinder's moving force.
No, the clamp locks only after the cylinder has stopped; it is not a dynamic brake. Additionally, it must be unlocked with balanced air pressures on both sides to prevent the rod from jumping abruptly.
