Airtac BSAI Locking Clamp Cylinder BSAI63X600
The AirTAC Airtac BSAI Locking Clamp Cylinder BSAI63X600 is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 600mm stroke and a spring-applied, air-released clamp-lock that holds the rod at ANY position along its travel — with a static holding force of 2200 N.

About the Airtac BSAI Locking Clamp Cylinder BSAI63X600
The AirTAC BSAI63X600 is a double-acting ISO 15552 profile cylinder equipped with a built-in clamp-lock mechanism. A spring-applied, air-released gripper clamps the piston rod to secure the load at any position along the 600 mm stroke. It delivers a static holding force of 2200 N, which is distinct from the cylinder thrust (1559 N push at 0.5 MPa). You must size the holding force against the static load, not the thrust. The enclasp mechanism uses a third G1/8 port to release the lock, requiring balanced air pressure to prevent abrupt rod movement.
This model features a carbon steel rod and PT tapered ports. The variable air cushion at both ends decelerates the piston near stroke limits but does not hold the load; the clamp performs that function. The base extruded aluminum barrel is dimensionally interchangeable per ISO 15552. Operating pressure is 0.15-0.7 MPa.

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 BSAI63X600 Is Used
Vertical Axis Hold
Locks a 63 mm bore rod at any point on a 600 mm vertical drop to prevent gravity-driven falls during work pauses.
Power Loss Safety
Spring-applied clamp engages instantly upon air loss, holding the 2200 N load securely mid-stroke without live pressure.
Machining Position Lock
Secures the workpiece rigidly at a custom intermediate stroke length for milling or inspection operations.
Is the Airtac BSAI Locking Clamp Cylinder BSAI63X600 the Right Clamp-Lock?
Choose this 63 mm bore if you need 1559 N push thrust at 0.5 MPa combined with mid-stroke holding. Stepping down to a 50 mm bore yields 982 N thrust and 1400 N holding force, while an 80 mm bore provides 2513 N thrust and 3600 N hold. Select BSAI over SAIL when you must lock at any position rather than only at stroke ends. For a plain SAI without a lock, the cylinder operates normally without clamping.
The clamp locks only after the rod stops; it cannot brake a moving load. Unlock requires balanced pressures to avoid rod jumping, and safety-critical applications need an independent measure. This 600 mm stroke uses an M16x1.5 rod thread; given the length, an external guide is recommended to handle side loads. Mounting options include Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, and TCM2. Sensors are not included.
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 BSAI63X600 FAQ
The static holding force is 2200 N, which is the clamp's grip on the rod. This is separate from the 1559 N push thrust at 0.5 MPa; size the holding force to your static load.
No, the clamp locks only after the cylinder has stopped. It cannot brake a moving rod. Unlocking requires balanced air pressures to prevent abrupt movement, and human safety requires an independent measure.
