About the Airtac BSAI Locking Clamp Cylinder BSAI63X1000S
The AirTAC BSAI63X1000-S is a double-acting ISO 15552 profile cylinder equipped with a spring-applied, air-released clamp-lock mechanism. It delivers 1559N of thrust at 0.5MPa and features a built-in gripper that secures the piston rod at any position along its 1000mm travel. This bidirectional lock provides a static holding force of 2200N. It is crucial to distinguish this holding force from the cylinder thrust; the clamp resists external static loads independently of the 2182N maximum push force generated at 0.7MPa.
This model includes a magnet for CMSE reed and DMSE electronic sensors. The clamping mechanism utilizes a third G1/8 enclasp port, separate from the 3/8 cylinder ports, requiring 0.15-0.7MPa to release. Remember that the variable air cushion only decelerates the piston near stroke ends, while the clamp itself performs the actual load holding. The lock engages strictly after the rod stops moving and cannot act as a dynamic brake.

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 BSAI63X1000S Is Used
Vertical Axis Holding
Maintains vertical loads securely at any point along the 1000mm travel without relying on continuous air pressure.
Emergency Drop Prevention
Spring-applied clamp engages instantly upon power loss to halt workpiece descent, though it requires an independent safety measure for human safety.
Machining Position Lock
Secures the part rigidly during drilling or inspection processes, ensuring the cushion does not bear the cutting load.
Is the Airtac BSAI Locking Clamp Cylinder BSAI63X1000S the Right Clamp-Lock?
Choose this 63mm bore model when an application requires position holding mid-stroke, unlike a SAIL cylinder which only locks at stroke ends. If less holding force is needed, the 50mm bore offers 1400N holding and 982N thrust at 0.5MPa; for heavier loads, the 80mm bore provides 3600N holding and 2513N thrust. A plain SAI cylinder suffices if no mid-stroke locking is required. Because this 1000mm stroke exceeds the 700mm standard limit for this bore, it is a non-standard stroke. The 20mm rod with an M16x1.5 thread handles side loads well, but an external guide is mandatory for this long unsupported length. Ensure replacement matches single-rod, PT ports, and the BSAI mounting set (Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, TCM2).
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 BSAI63X1000S FAQ
The clamp-lock provides a static holding force of 2200N. It locks at any position bidirectionally, but only after the cylinder has stopped moving; it cannot brake a moving rod.
The lock is air-released via a third G1/8 enclasp port. You must balance the air pressures on both sides of the piston before unlocking, otherwise the rod may move abruptly.
