Airtac BSAID Clamp Cylinder BSAID80X700S
The AirTAC Airtac BSAID Clamp Cylinder BSAID80X700S is a genuine double-acting ISO 15552 cylinder with a Ø80mm 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 3600 N.

About the Airtac BSAID Clamp Cylinder BSAID80X700S
The AirTAC BSAID80X700-S is a double-acting ISO 15552 profile cylinder featuring a rod extending from both ends and a built-in spring-applied, air-released clamp-lock. It delivers equal thrust in both directions, generating 2268 N of pull force at 0.5 MPa. A defining reason to choose this enclasp model is its ability to lock the piston at any position along the 700 mm travel, providing a documented static holding force of 3600 N. It is crucial to distinguish this holding force from the cylinder thrust; the clamp sustains a static load independently of the 2268 N drive force, so you must size the holding capacity against the load weight, not the thrust.
Because the base cylinder is an extruded aluminum profile type (never a tie-rod), it is dimensionally interchangeable per ISO 15552. The double-rod layout lets you mount a workpiece on one end and a guide, counterweight, or position flag on the opposite end, delivering dual-side guidance and anti-rotation stability. The clamp operates via a third G1/8 enclasp port, and the variable air cushions at both ends only decelerate the piston near stroke end—they do not hold the load. This model includes a magnet (-S) for precise position sensing with AirTAC CMSE reed and DMSE solid-state switches.

How the Clamp-Lock Holds
static holding force (Ø80 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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa (max) | 3519 N | — |
Equal force both directions (double rod). Rated to the 0.7 MPa operating maximum for this series. The clamp holding force (3600 N) is separate from cylinder thrust. Size with a margin.
Where the Airtac BSAID Clamp Cylinder BSAID80X700S Is Used
Vertical Axis Load Holding
Secures a heavy vertical lift at any intermediate height during a power loss, holding the load safely with 3600 N of static force.
Machining Position Lock
Locks a dual-sided workpiece fixture rigidly in place for a machining or inspection process, using the second rod end for anti-rotation guidance.
Mid-Stroke Emergency Stop
Clamps the piston rod immediately after a conveyor actuator stops mid-travel, preventing drift while maintaining equal force both directions.
Is the Airtac BSAID Clamp Cylinder BSAID80X700S the Right Clamp-Lock?
Step up to the 100 mm bore if you need greater drive force (3681 N pull at 0.5 MPa) and a higher 5500 N holding force, or step down to the 63 mm bore for lighter loads (1402 N pull, 2200 N hold). Choose this BSAID clamp-lock over a plain SAID when you must secure a load at an intermediate stroke position, not just at the ends. It also outperforms a SAIL stroke-end lock by gripping the rod anywhere. Remember the operational limits: the clamp locks only after the rod has stopped moving—it cannot brake a moving rod—and you must unlock it with balanced air pressures on both sides of the piston to prevent the rod from jumping abruptly. For human-safety critical holds, add an independent external safety measure.
This BSAID80X700-S replacement features an 80 mm bore, 700 mm stroke, PT tapered ports (3/8 cylinder port, G1/8 enclasp port), and a carbon steel rod with an M20x1.5 thread. The large 25 mm rod diameter and robust thread handle high side loads well, but at 700 mm of stroke, an external guide rail is strongly recommended to prevent rod deflection. The double-rod design restricts mounting options to Basic, FA, LB, TC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). The integrated magnet works seamlessly with CMSE and DMSE sensors.
Quick checklist
- ✓ Hold needed at any position?
- ✓ Or stroke-end only → use SAIL
- ✓ Holding force ≥ your load
- ✓ Balanced-pressure unlock circuit

Airtac BSAID Clamp Cylinder BSAID80X700S FAQ
The clamp-lock provides a static holding force of 3600 N. It is a spring-applied, air-released mechanism that grips the rod to hold the load at any position along the stroke, operating bidirectionally whether the rod was extending or retracting.
The clamp locks only after the cylinder has stopped moving; it cannot brake a moving rod. To unlock it safely, you must apply air to the G1/8 enclasp port while balancing the air pressures on both sides of the piston, otherwise the rod may jump abruptly. For safety-critical applications, an independent external safety measure is required.
