Airtac BSAID Clamp Cylinder BSAID100X700S
The AirTAC Airtac BSAID Clamp Cylinder BSAID100X700S is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 700mm 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 5500 N.

About the Airtac BSAID Clamp Cylinder BSAID100X700S
The AirTAC BSAID100X700-S is a double-acting ISO 15552 profile cylinder featuring a double-rod design and a spring-applied, air-released clamp-lock mechanism. It secures the load at any position along the 700mm stroke with a robust 5500 N static holding force. Because it is a double-rod unit, the thrust is equal in both directions at 3681 N (0.5 MPa), and the second rod allows you to mount a position flag, secondary tool, or guide on the opposite end for dual-side guidance and anti-rotation.
It is crucial to distinguish this 5500 N static holding force from the cylinder's 3681 N thrust—the clamp's job is to hold a stationary load, not to move it. The clamp also uses a separate G1/8 enclasp port and requires 0.15-0.7 MPa operating pressure to function safely. Remember that the variable air cushion only decelerates the piston near stroke ends; the clamp itself is what holds the load. Furthermore, the lock engages only after the rod stops, and it must be unlocked with balanced air pressures 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 | — |
Equal force both directions (double rod). 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 BSAID Clamp Cylinder BSAID100X700S Is Used
Vertical Axis Holding
Prevents gravity-driven drops on vertical lifts by clamping the rod securely at any mid-stroke position during power loss.
Machining Position Lock
Holds a workpiece stationary against machining forces using the 5500 N clamp, with the second rod supporting a counter-tool.
Emergency Safety Stop
Provides a reliable halt in travel for safety gates, but requires an independent safety measure for human loads.
Is the Airtac BSAID Clamp Cylinder BSAID100X700S the Right Clamp-Lock?
Choose this 100mm bore double-rod model when your application requires 3681 N of thrust both ways and 5500 N of holding power mid-stroke. If you need less force, stepping down to the 80mm bore provides 2268 N pull thrust and 3600 N holding force. If you only need to hold the load at the stroke ends, a plain SAI or SAID cylinder suffices, but BSAID is necessary for locking anywhere in the travel. For safety, note that the clamp locks only after the rod stops—it cannot brake a moving load—and human-safety applications require an independent backup measure.
As a replacement, verify the double-rod configuration, 100mm bore, 700mm stroke, PT port threads, and the -S magnet for CMSE reed and DMSE electronic sensors. The M20x1.5 rod thread and 25mm rod diameter handle high side loads, but at 700mm stroke, an external guide rail is highly recommended to prevent binding. Mounting options for this double-rod version include Basic, FA, LB, TC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).
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 BSAID Clamp Cylinder BSAID100X700S FAQ
The spring-applied clamp-lock provides a static holding force of 5500 N. It engages bidirectionally at any position along the stroke, but only after the rod has completely stopped moving.
The clamp is released via a G1/8 enclasp port, but only when air pressures on both sides of the piston are balanced to prevent the rod from jumping. BSAID features a rod out both ends for dual-side mounting, whereas BSAI is a single-rod design.
