About the Airtac BSAI Locking Clamp Cylinder BSAI32X450
The AirTAC BSAI32X450 is a double-acting ISO 15552 profile cylinder featuring a built-in spring-applied, air-released clamp-lock. It secures the carbon steel piston rod at any position along its 450mm travel, providing a static holding force of 600N. Because it is a profile cylinder with an extruded aluminum barrel, it integrates cleanly into modern pneumatic setups. The clamping mechanism is bidirectional, maintaining the load securely whether the rod was extending or retracting.
It is crucial to distinguish the 600N static holding force from the cylinder's 402N thrust at 0.5MPa; the clamp's job is to hold a stationary load, not to generate motive force. The variable air cushion only decelerates the piston near the stroke ends and is not a holding device. To release the lock, air must be applied to the dedicated G1/8 enclasp port, but this requires balanced 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 BSAI32X450 Is Used
Vertical Z-Axis Holding
Prevents a 32mm bore vertical load from dropping when air pressure is removed, locking the rod securely at any intermediate height along the 450mm stroke.
Power Loss Safety
The spring-applied clamp engages automatically during an air or power failure, freezing the piston mid-stroke to protect the work area.
Machining Position Hold
Locks the extended rod rigidly at a specific intermediate point for secure part machining or inspection without continuous pneumatic pressure.
Is the Airtac BSAI Locking Clamp Cylinder BSAI32X450 the Right Clamp-Lock?
Choose this 32mm bore if your application needs mid-stroke holding that a plain SAI cannot provide, or if a SAIL stroke-end lock is insufficient for your 450mm travel. If you need to hold a heavier load, stepping up to the 40mm bore increases the holding force to 900N and the thrust to 528N. The BSAI32X450 operates at 0.15-0.7MPa with a speed range of 30-800mm/s. Because this is a 450mm stroke, the 12mm rod and M10x1.25 thread will experience amplified leverage on side loads; an external guide rail is recommended to prevent binding. This unit uses PT tapered ports, a 1/8 cylinder port, and accepts Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, or TCM2 mounts. Note that the clamp only engages after the rod stops moving and is not a dynamic brake; safety-critical applications require 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 BSAI32X450 FAQ
The clamp-lock provides a static holding force of 600N. It engages via a spring-applied mechanism to hold the rod at any position bidirectionally, but it only locks after the cylinder has completely stopped moving.
The lock is released by applying air to the dedicated G1/8 enclasp port. However, you must ensure the air pressures on both sides of the piston are balanced before unlocking, otherwise the rod may move abruptly and cause a hazard.
