About the Airtac BSAID Clamp Cylinder BSAID80X160S
The AirTAC BSAID80X160-S is a double-acting ISO 15552 profile cylinder featuring a rod extending from both ends and an integrated spring-applied, air-released clamp-lock. It delivers an equal thrust of 2268 N in both directions at 0.5 MPa, while the separate enclasp mechanism provides a static holding force of 3600 N. It is crucial to distinguish this holding force from the cylinder thrust: the clamp resists external static loads, whereas the thrust dictates movement capability.
The clamp locks the carbon steel rod at any position along the 160 mm stroke and is bidirectional. Unlike the variable air cushion, which only decelerates the piston near stroke ends, the clamp physically secures the load. The double-rod design allows mounting a workpiece on one end and a guide or position flag on the other, providing dual-side guidance and anti-rotation. A third G1/8 PT port supplies the 0.15-0.7 MPa unlock pressure, and the included -S magnet pairs with CMSE reed and DMSE electronic sensors.

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 BSAID80X160S Is Used
Vertical Lift Anti-Drop
Holds a lifted load securely at any intermediate vertical position during power loss, preventing sudden drops.
Machining Position Hold
Locks the dual rods rigidly to resist cutting forces during clamping, machining, or inspection processes.
Dual-Side Tooling Transfer
Mounts a workpiece on one rod end and a counterweight or position flag on the opposite end for balanced guidance.
Is the Airtac BSAID Clamp Cylinder BSAID80X160S the Right Clamp-Lock?
Choose this double-rod model when your application requires equal force both ways and anti-rotation guidance via a secondary rod end. If you only need unidirectional thrust, the single-rod BSAI80X160-S offers identical 3600 N holding in a smaller footprint. For lighter loads, the bore 63 version provides 1402 N thrust and 2200 N holding force. The BSAID80X160-S clamp locks only after the rod stops; it cannot brake a moving load. Always balance air pressure on both piston sides before unlocking, or the rod may jump abruptly. Safety-critical applications require an independent external holding measure.
Replacement specifications: 80 mm bore, 160 mm stroke, double carbon steel rod, PT ported (3/8 cylinder, G1/8 enclasp). Compatible mounts exclude FB, CA, CB, and CR; use Basic, FA, LB, TC, TCM1, or TCM2. The M20x1.5 rod thread handles high side loads, though external guides are recommended for long strokes.
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 BSAID80X160S FAQ
The integrated clamp-lock provides a static holding force of 3600 N. It engages via spring force and locks the rod at any position bidirectionally, but only after the cylinder has stopped moving.
You must apply 0.15-0.7 MPa to the G1/8 enclasp port only after balancing air pressures on both sides of the piston. Releasing the clamp with unbalanced pressures can cause the rod to jump abruptly.
