About the Airtac BSAI Locking Clamp Cylinder BSAI32X450S
The AirTAC BSAI32X450-S is a double-acting ISO 15552 profile cylinder featuring a built-in spring-applied, air-released enclasp mechanism. A defining trait of this series is the capacity to lock the piston rod at ANY position along the 450mm travel, not just at the stroke ends. It provides a documented static holding force of 600 N to secure the load. The base pneumatic thrust is 402 N push and 345 N pull at 0.5 MPa, but buyers must distinguish holding force from thrust: the 600 N clamp rating is the metric for static load safety, entirely separate from the cylinder's movement force.
This clamping action is engaged by a spring and released by air pressure applied to a dedicated G1/8 enclasp port, which operates independently from the standard PT 1/8 cylinder ports. The variable air cushion at the stroke ends only decelerates the piston to prevent impact damage; it does not hold the load. The integrated -S magnet supports position detection via AirTAC CMSE reed or DMSE solid-state sensors. Because the 450mm stroke is long for a 32mm bore, an external guide rail is strongly recommended to prevent excessive rod side-loading.

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 BSAI32X450S Is Used
Vertical Axis Hold
Secures a 32mm bore vertical lift at any intermediate height during a power loss, relying on the 600N static holding force to prevent gravity-driven drops.
Machining Position Lock
Freezes the rod at a specific 450mm travel coordinate for secondary machining or inspection, ensuring the workpiece remains completely stationary without live air pressure.
Emergency Safety Stop
Acts as an enclasp gripper to hold a payload safely in mid-stroke during an unexpected air supply drop, provided the rod has already ceased motion.
Is the Airtac BSAI Locking Clamp Cylinder BSAI32X450S the Right Clamp-Lock?
Select this 32mm bore model when intermediate-position holding is required along a 450mm travel path. If a project only requires locking at the fully extended or retracted stroke ends, the AirTAC SAIL series is a simpler choice, whereas the BSAI is explicitly designed for enclasp gripping anywhere in transit. If no clamping is needed at all, a standard SAI cylinder suffices. For higher load security, stepping up to a 40mm bore increases the holding force to 900 N and the 0.5 MPa thrust to 628 N.
Replacement matching requires a single-rod configuration, 32mm bore, 450mm stroke, and PT tapered port threads. The -S magnet enables CMSE and DMSE sensor compatibility. Mounting options include Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, and TCM2. Operation is limited to 0.15-0.7 MPa. Remember the clamp locks only after the rod stops; it cannot brake a moving load. Furthermore, unlocking requires balanced air pressures on both piston sides to prevent the rod from jumping abruptly. Safety-critical applications must use 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 BSAI32X450S FAQ
The integrated enclasp mechanism provides a static holding force of 600 N. This allows the cylinder to lock and hold the load at any position along the 450mm stroke, not just at the ends. The clamp engages via spring force and is released using air pressure.
No. The clamp locks only after the cylinder has come to a complete stop; it cannot decelerate a moving rod. Additionally, the clamp must be unlocked by balancing the air pressure on both sides of the piston, or the rod may jump abruptly. Human-safety applications require an independent external safety measure.
