Airtac BSAID Clamp Cylinder BSAID80X125
The AirTAC Airtac BSAID Clamp Cylinder BSAID80X125 is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 125mm 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 BSAID80X125
The AirTAC BSAID80X125 is a double-acting ISO 15552 profile cylinder featuring a double-rod layout and an integrated clamp-lock mechanism. A spring-applied, air-released gripper secures the piston rod at any point along its 125 mm travel, delivering a static holding force of 3600 N. Because it is a double-rod design, the thrust is equal in both directions at 2268 N (0.5 MPa), and the second rod allows you to mount a position flag or secondary tool on the opposite end for dual-side guidance.
It is vital to distinguish this 3600 N static holding force from the cylinder's 2268 N thrust; you must size the clamp against the static load, not the drive force. The clamp operates via a separate G1/8 enclasp port, while the main cylinder uses 3/8 PT ports. Remember that the variable air cushions only decelerate the piston near the stroke ends, whereas the mechanical clamp is what actually secures the load.

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 BSAID80X125 Is Used
Vertical Axis Hold
Secures a 2268 N lift anywhere along its vertical travel to prevent gravity drops during an air loss event.
Machining Position Lock
Clamps the dual rods at a precise mid-stroke coordinate for milling or inspection without live pressure.
Dual-Side Emergency Stop
Holds the load securely using the second rod for a counterweight or guide during unexpected power failure.
Is the Airtac BSAID Clamp Cylinder BSAID80X125 the Right Clamp-Lock?
Choose this 80 mm bore when an application demands 2268 N of force in both directions and a mid-stroke hold; if less force is needed, the 63 mm bore offers 1402 N thrust and a 2200 N hold. Select this BSAID model over a stroke-end-only SAIL lock when you must secure the load anywhere in the travel, or choose a plain SAID if no clamping is required. The clamp locks only after the rod has stopped, so it cannot brake a moving load, and it must be unlocked with balanced air pressures to prevent the rod from jumping abruptly.
For safety-critical loads, provide an independent external safety measure. This configuration features a 25 mm carbon steel rod with an M20x1.5 thread, which handles side loads well, but always use external guides for long strokes. The drop-in replacement match is a double-rod, 80 mm bore, 125 mm stroke cylinder with PT ports, accepting Basic, FA, LB, TC, TCM1, or TCM2 mounts (omitting FB/CA/CB/CR). Add an -S magnet if CMSE reed or DMSE electronic sensors are needed.
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 BSAID80X125 FAQ
It uses a spring-applied, air-released mechanism to grip the rod at any position with a 3600 N static holding force. Because it is a double-rod cylinder, this holding force and the thrust are equal in both directions.
No, the clamp locks only after the cylinder has stopped and cannot brake a moving rod. It must be unlocked with balanced air pressures to prevent abrupt rod movement, and safety-critical applications require an independent safety measure.
