About the Airtac BSAI Locking Clamp Cylinder BSAI32X50
The AirTAC BSAI32X50 is a double-acting profile cylinder with a built-in clamp-lock, dimensionally interchangeable per ISO 15552. It uses a spring-applied, air-released mechanism to grip the 12mm carbon steel piston rod, holding the load at any position along its 50mm stroke. The integrated clamp delivers a static holding force of 600 N, which is a separate metric from the cylinder's 563 N maximum thrust at 0.7 MPa. Buyers must size the holding force against the static load, not the thrust.
Unlike the variable air cushion that merely decelerates the piston near stroke end, the clamp physically secures the rod. It operates via a third G1/8 enclasp port, requiring 0.15-0.7 MPa to release. Because it locks only after the cylinder stops, it cannot brake a moving rod. Furthermore, unlocking requires balanced air pressures on both sides of the piston to prevent abrupt rod movement.

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 BSAI32X50 Is Used
Vertical Axis Hold
Prevents gravity-driven drops on vertical strokes by gripping the rod at any point, securing the load without relying on live air pressure.
Power Loss Safety
Spring-applied clamping engages automatically during air or power loss, freezing the piston in its exact travel position until pressure is restored.
Machining Position Hold
Locks the workpiece rigidly at a specific intermediate point for drilling or inspection, ensuring no deflection during the process.
Is the Airtac BSAI Locking Clamp Cylinder BSAI32X50 the Right Clamp-Lock?
Choose this 32mm bore if your application needs mid-stroke holding rather than just end-of-stroke retention, making it superior to a SAIL model. If the 600 N holding force is insufficient, step up to the 40mm bore, which provides 900 N of holding force and 628 N of thrust at 0.5 MPa. If no locking is required at all, a plain SAI cylinder suffices. For safety-critical loads, add an independent mechanical measure.
This BSAI32X50 has a 50mm stroke, a 1/8 PT cylinder port, and an M10x1.25 rod thread. It supports Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, and TCM2 mounts. Without a magnet specified, it omits CMSE/DMSE sensing. The 12mm rod handles side loads well, but long unsupported strokes still need an external guide.
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 BSAI32X50 FAQ
The clamp-lock provides a static holding force of 600 N. It locks bidirectionally at any position along the stroke, but only after the rod has stopped moving.
The clamp is released via a third G1/8 enclasp port. You must balance the air pressures on both sides of the piston before unlocking, or the rod may jump abruptly. It cannot brake a moving rod.
