About the Airtac BSAI Locking Clamp Cylinder BSAI32X350
The AirTAC BSAI32X350 is a double-acting ISO 15552 profile cylinder featuring a built-in clamp-lock mechanism. It provides a static holding force of 600 N and locks the piston rod at any position along its 350 mm travel. Delivering a practical maximum thrust of 563 N at 0.7 MPa, this unit distinguishes holding force from thrust: the 600 N clamp rating secures the static load, while the 563 N thrust dictates the movement capability.
The spring-applied, air-released gripper activates via a separate G1/8 enclasp port, independent of the 1/8 cylinder ports. Remember that the variable air cushion only decelerates the piston near stroke ends; the clamp itself is what holds the load. The lock engages solely after the rod has completely stopped, meaning it cannot brake 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 BSAI32X350 Is Used
Vertical Load Holding
Secures a 32 mm bore vertical axis at any point in its 350 mm stroke, preventing gravity-driven drops during air pressure loss.
Machining Position Lock
Holds a workpiece firmly in a specific location for drilling or inspection, utilizing the 600 N static clamp force.
Mid-Stroke Safety Hold
Acts as an emergency stop lock that engages only after cylinder motion stops, safely freezing the rod position.
Is the Airtac BSAI Locking Clamp Cylinder BSAI32X350 the Right Clamp-Lock?
Choose this 32 mm bore when an application requires mid-stroke holding rather than just end-of-stroke stopping, making it preferable to a SAIL model which only locks at stroke ends. If your load requires a higher holding capacity, stepping up to a 40 mm bore increases the clamp force to 900 N and thrust to 879 N at 0.7 MPa. For simple extension and retraction without position holding, a plain SAI cylinder is sufficient. Because this stroke is 350 mm, an external guide is recommended to prevent side-loading on the 12 mm carbon steel rod.
Ensure safe operation by balancing air pressures on both sides of the piston before unlocking; otherwise, the rod may jump abruptly. If human safety relies on the hold, add an independent mechanical safety measure. This configuration features PT tapered ports, standard carbon steel rod, and no magnet. It accepts Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, and TCM2 mounts.
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 BSAI32X350 FAQ
The BSAI32X350 provides a static holding force of 600 N. This clamp force is entirely separate from the cylinder's 563 N thrust at 0.7 MPa, and it holds the rod at any position along the stroke.
The clamp is spring-applied and air-released via a G1/8 port. It only locks after the rod has stopped moving and cannot brake a moving load. You must balance air pressures on both sides of the piston before unlocking to prevent the rod from jumping abruptly.
