About the Airtac BSAI Locking Clamp Cylinder BSAI63X500
The AirTAC BSAI63X500 is a double-acting ISO 15552 profile cylinder featuring a built-in spring-applied, air-released clamp-lock. It delivers a practical maximum thrust of 2182 N at 0.7 MPa, while the integrated enclasp mechanism provides a distinct static holding force of 2200 N. Buyers must distinguish between these two ratings: thrust moves the load, but the clamp's holding force is what secures the static payload at rest.
This bidirectional lock engages at any position along the 500 mm travel, activated via a separate G1/8 enclasp port. It is critical to note the variable air cushion only decelerates the piston near stroke ends; it does not hold the load. Furthermore, the clamp locks only after the rod has completely stopped and cannot serve as a braking device for a moving load.

How the Clamp-Lock Holds
static holding force (Ø63 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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa (max) | 2182 N | — |
Push/pull as tabulated. Rated to the 0.7 MPa operating maximum for this series. The clamp holding force (2200 N) is separate from cylinder thrust. Size with a margin.
Where the Airtac BSAI Locking Clamp Cylinder BSAI63X500 Is Used
Vertical Axis Holding
Prevents gravity-driven drops on vertical lifts by clamping the 20 mm rod securely at any point in the 500 mm travel, sustaining 2200 N of static payload.
Power Outage Safety
The spring-applied mechanism engages automatically upon air loss, freezing the load exactly where it stopped without requiring continuous pressure.
Machining Position Hold
Locks the workpiece rigidly at a specific intermediate stroke for drilling or inspection, ensuring the variable cushion does not bear the cutting forces.
Is the Airtac BSAI Locking Clamp Cylinder BSAI63X500 the Right Clamp-Lock?
Choose this 63 mm bore when a 50 mm bore (982 N thrust at 0.5 MPa, 1400 N holding force) lacks sufficient load capacity, but an 80 mm bore (2513 N thrust at 0.5 MPa, 3600 N holding force) is physically oversized. The BSAI63X500 is preferred over a SAIL model when you need to secure the load at an intermediate stroke position rather than only at the stroke end. A standard SAI suffices if no position holding is required.
This configuration features a carbon steel rod with PT tapered ports and no sensor magnet. It accepts Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, and TCM2 mounts. Because the 500 mm stroke is lengthy, an external guide is recommended to prevent excessive side-loading on the 20 mm rod. To release the clamp safely, balance the air pressure on both sides of the piston to prevent the rod from jumping abruptly.
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 BSAI63X500 FAQ
The integrated clamp-lock provides a static holding force of 2200 N. It clamps the rod bidirectionally at any position along the 500 mm stroke, but only after the cylinder has stopped moving.
The clamp uses a third G1/8 enclasp port. To unlock safely, you must balance the air pressure on both sides of the piston first; otherwise, releasing the clamp can cause the rod to jump abruptly.
