About the Airtac BSAI Locking Clamp Cylinder BSAI32X500
The AirTAC BSAI32X500 is a double-acting ISO 15552 profile cylinder with a spring-applied, air-released clamp-lock that grips the 12 mm carbon steel rod at any position along its 500 mm stroke. It delivers a practical thrust of 563 N at 0.7 MPa, but the defining feature is its 600 N static holding force. Buyers must distinguish holding force from thrust: the clamp's 600 N rating is the true measure of static load capacity when air pressure is removed, not the cylinder's push force.
This enclasp mechanism is bidirectional and operates via a dedicated G1/8 unlock port, requiring 0.15-0.7 MPa to release the spring tension. Remember that the variable air cushion only decelerates the piston near stroke ends; it does not hold the load. The clamp locks only after the rod has completely stopped, so it cannot serve as a dynamic brake for a moving load.

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 BSAI32X500 Is Used
Vertical Axis Mid-Stroke Hold
Locks a 500 mm vertical lift at any intermediate height with 600 N of holding force, preventing gravity-driven drops during an air pressure loss.
Emergency Power-Loss Stop
Freezes the piston exactly where it stopped moving when power fails, securing the load safely without needing continuous pneumatic pressure.
Machining Position Freeze
Holds the workpiece steady at a custom stroke position for machining or inspection, ensuring the clamp grips the rod firmly while work is performed.
Is the Airtac BSAI Locking Clamp Cylinder BSAI32X500 the Right Clamp-Lock?
Choose this 32 mm bore if your vertical or horizontal axis needs to freeze mid-travel without maintaining live air pressure. If 600 N of static hold is insufficient, step up to the 40 mm bore, which provides 900 N holding force and 879 N thrust at 0.7 MPa. Conversely, if you only need to hold the load at the stroke ends, a plain SAIL stroke-end lock or a standard SAI cylinder is more cost-effective.
For a direct replacement, match the single-rod configuration, 500 mm stroke, PT tapered ports (1/8 cylinder port, G1/8 enclasp port), and the BSAI mounting set (Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, TCM2). Because the 500 mm stroke is long relative to the 12 mm rod, an external guide rail is strongly recommended to prevent side-load damage. Note that this unit lacks a magnet; add an -S suffix if CMSE reed or DMSE solid-state sensors are needed.
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 BSAI32X500 FAQ
The clamp-lock provides a static holding force of 600 N. It can hold the load at any position along the 500 mm stroke, but it only engages after the piston has stopped moving; it cannot brake a moving rod.
You must apply 0.15-0.7 MPa of air to the G1/8 enclasp port, but only after the air pressures on both sides of the piston are balanced. If pressures are not balanced, the rod may jump abruptly upon release.
