About the Airtac BSAI Locking Clamp Cylinder BSAI32X160
The AirTAC BSAI32X160 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 at any position along its 160 mm stroke. Delivering a practical maximum thrust of 563 N at 0.7 MPa, this 32 mm bore unit distinguishes holding force from thrust: the 600 N clamp secures the static load independently of the cylinder's push power, meaning you must size the hold against the load weight, not the actuator's thrust. The lock engages bidirectionally and requires a third G1/8 enclasp port to release.
It is crucial to understand that the variable air cushion only decelerates the piston near the stroke end; the mechanical clamp is what actually holds the load. The BSAI lock engages only after the rod has stopped, so it cannot brake a moving actuator. Furthermore, unlocking requires balanced air pressures 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 BSAI32X160 Is Used
Vertical Axis Hold
Maintains a 600 N load securely at any point on a vertical lift when air pressure is removed, preventing gravity-driven drops.
Power Loss Safety
Spring-applied clamp immediately grips the 12 mm rod to freeze the 160 mm stroke in place during an unexpected pneumatic power failure.
Machining Position Hold
Locks the workpiece rigidly at a specific non-end stroke coordinate for machining or inspection, functioning separately from the air cushion.
Is the Airtac BSAI Locking Clamp Cylinder BSAI32X160 the Right Clamp-Lock?
Choose this 32 mm bore model when an application demands position holding mid-stroke rather than just at the end points, which is where the BSAI surpasses the stroke-end-only SAIL variant. If your load requires less holding capacity, stepping down is not an option since 32 mm is the smallest bore, but stepping up to a 40 mm bore provides 900 N of holding force and 879 N of thrust at 0.7 MPa. If no locking is needed at all, a plain SAI cylinder suffices. For safety-critical loads, an additional independent safety measure is required, as the clamp cannot stop a moving rod.
This BSAI32X160 configuration features a single carbon steel rod with an M10x1.25 thread, PT tapered port threads (1/8 cylinder port), and no magnet. It supports Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, and TCM2 mounts. The 160 mm stroke is well within standard limits, but the 12 mm rod diameter handles limited side loads; for any stroke over 300 mm, an external guide is recommended to prevent rod bending.
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 BSAI32X160 FAQ
The BSAI32X160 provides a static holding force of 600 N. The clamp is spring-applied and air-released, meaning it grips the rod automatically at any stroke position without needing continuous air pressure.
The lock only engages after the cylinder has stopped moving and cannot brake a moving rod. To release it safely, air pressure must be balanced on both sides of the piston via the G1/8 enclasp port; otherwise, the rod may jump abruptly. Safety-critical applications require an independent backup measure.
