About the Airtac BSAI Locking Clamp Cylinder BSAI100X700
The AirTAC BSAI100X700 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 5497 N at 0.7 MPa, but its defining feature is the ability to hold a static load of 5500 N at any position along its 700 mm stroke. Buyers must distinguish this holding force from thrust: the 5500 N clamp rating dictates the static load capacity when air pressure is removed, whereas the 5497 N thrust drives the motion.
This bidirectional enclasp locks the 25 mm carbon steel rod only after the cylinder has stopped, meaning it cannot brake a moving load. The lock releases via a separate G1/8 enclasp port, requiring balanced air pressure on both sides of the piston to prevent the rod from jumping abruptly upon release. Additionally, the variable air cushion at the stroke ends only decelerates the piston; the mechanical clamp is the true holding mechanism.

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 BSAI100X700 Is Used
Vertical Axis Hold
Prevents gravity-driven drops on vertical strokes by clamping the rod securely at any intermediate height.
Power Loss Safety
Engages the 5500 N spring-applied lock instantly during air pressure loss to freeze the load in place.
Machining Position Hold
Locks the workpiece rigidly at a specific mid-stroke coordinate for milling or inspection processes.
Is the Airtac BSAI Locking Clamp Cylinder BSAI100X700 the Right Clamp-Lock?
Choose this 100 mm bore if your load requires the 5500 N holding capacity or the 5497 N thrust class. If your application only needs holding at the stroke ends, a plain SAI or SAIL cylinder suffices, but BSAI is required for mid-stroke positioning. Stepping down to a 63 mm bore reduces the holding capacity to 2200 N and thrust to 1402 N at 0.5 MPa. Because this model features a 700 mm stroke, an external guide is recommended to handle side loads despite the robust 25 mm rod and M20x1.5 thread.
For safe operation, remember the clamp engages after the rod stops and requires balanced pressure to unlock safely. This single-rod configuration accepts Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, and TCM2 mounts. It uses PT port threads (1/2 inch cylinder port plus the G1/8 enclasp port) and ships without a magnet, so it is not compatible with CMSE or DMSE sensors without modification.
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 BSAI100X700 FAQ
The BSAI100X700 provides a static holding force of 5500 N. This clamp engages via spring pressure to hold the load at any position along the 700 mm stroke, operating bidirectionally.
The clamp must only be unlocked after the cylinder has stopped and the air pressures on both sides of the piston are balanced. Air is supplied to the separate G1/8 enclasp port to release the spring clamp; failing to balance the pressure can cause the rod to jump abruptly.
