About the Airtac BSAI Locking Clamp Cylinder BSAI100X600
The AirTAC BSAI100X600 is a double-acting ISO 15552 profile cylinder featuring a spring-applied, air-released clamp-lock mechanism. It provides a static holding force of 5500 N, gripping the 25mm carbon steel rod securely at any position along its 600mm travel. The base cylinder generates 3927 N of push thrust at 0.5 MPa, but the holding force and thrust are distinct quantities; you must size the clamp's 5500 N capacity against your static load, not the cylinder's thrust.
This enclasp unit operates at 0.15-0.7 MPa and uses a third G1/8 unlock port to release the grip. It locks only after the piston has stopped moving and cannot act as a dynamic brake. Furthermore, the variable air cushion at the stroke ends only decelerates the piston; the mechanical clamp is what actually holds the load. Pressure must be balanced on both sides before unlocking to prevent the rod from jumping abruptly.

How the Clamp-Lock Holds
static holding force (Ø100 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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa (max) | 5498 N | — |
Push/pull as tabulated. Rated to the 0.7 MPa operating maximum for this series. The clamp holding force (5500 N) is separate from cylinder thrust. Size with a margin.
Where the Airtac BSAI Locking Clamp Cylinder BSAI100X600 Is Used
Vertical Load Holding
Securely freezes heavy vertical payloads at any point in the 600mm travel, preventing gravity-driven drops during an air pressure loss.
Machining Position Lock
Holds a workpiece completely stationary at a custom mid-stroke position for machining or inspection operations without bottoming out.
Power Loss Safety
The spring-applied clamp engages instantly when air drops, locking the stopped rod safely in place until pressure and balance are restored.
Is the Airtac BSAI Locking Clamp Cylinder BSAI100X600 the Right Clamp-Lock?
Choose this 100mm bore model when a load needs secure intermediate holding, stepping up from the 80mm bore which offers 2513 N thrust and 3600 N holding force. The BSAI100X600 is preferred over a SAIL stroke-end lock when you must freeze the rod mid-stroke rather than at the extremes. If live holding is sufficient, a plain SAI cylinder without the clamp head works. Because the 600mm stroke is long, an external guide is recommended to prevent side-load damage to the 25mm rod and M20x1.5 thread. Replacements require a single-rod configuration, 100mm bore, 600mm stroke, PT port threads, 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 BSAI100X600 FAQ
The clamp-lock provides a static holding force of 5500 N. It grips the rod bidirectionally at any position, but only after the cylinder has stopped moving; it is not a dynamic brake.
The clamp is released via a third G1/8 enclasp port at 0.15-0.7 MPa. You must balance the air pressures on both sides of the piston before unlocking, otherwise the rod can move abruptly. Safety-critical loads require an independent backup measure.
