About the Airtac BSAID Clamp Cylinder BSAID80X700
The AirTAC BSAID80X700 is a double-acting ISO 15552 profile cylinder featuring a double-rod construction and an integrated clamp-lock mechanism. A spring-applied, air-released gripper secures the piston rod at any position along its 700 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 (at 0.5 MPa), and the extending rod out both ends allows mounting a workpiece on one side and a counterweight or position flag on the other.
It is crucial to distinguish this 3600 N static holding force from the 2268 N cylinder thrust: the clamp sustains the static load without live air pressure, whereas thrust drives the motion. The clamp operates via a third G1/8 enclasp port and requires balanced cylinder pressures to unlock safely. Furthermore, the variable air cushion only decelerates the piston near stroke ends; the mechanical clamp is the sole device holding 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 BSAID80X700 Is Used
Vertical Axis Hold
Locks a heavy lifting platform at any intermediate height with 3600 N of holding force, preventing descent upon air loss without relying on end-stops.
Machining Positioning
Secures a dual-sided workpiece rigidly in place for machining or inspection, using the second rod for a position flag or counterweight.
Emergency Drop Prevention
Acts as a fail-safe gripper that clamps the rod instantly when pressure drops, holding the load stationary until pressure is restored.
Is the Airtac BSAID Clamp Cylinder BSAID80X700 the Right Clamp-Lock?
Choose this double-rod model when a workload requires dual-side guidance, anti-rotation, or a secondary tool on the opposite end. If you do not need a rod extending from the rear, the single-rod BSAI80X200 offers the same 3600 N holding force but with 2513 N push thrust. Alternatively, if holding is only needed at the stroke end, a SAIL cylinder suffices, but BSAI/BSAID is required for mid-stroke locking. For lighter vertical axes, the BSAID63X200 provides 1402 N thrust and 2200 N holding force.
This BSAID80X700 uses PT tapered ports (3/8 cylinder, G1/8 enclasp) and accepts Basic, FA, LB, TC, TCM1, or TCM2 mounts (omitting FB/CA/CB/CR). It operates at 0.15-0.7 MPa. Because the stroke is 700 mm, the M20x1.5 rod thread handles substantial side loads, but an external guide is still recommended for unsupported lengths. Note: the clamp locks only after the rod stops and is not a dynamic brake; safety-critical loads need an independent measure.
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 BSAID80X700 FAQ
The clamp-lock provides a static holding force of 3600 N. It is a spring-applied, air-released mechanism that grips the rod at any position along the stroke. It only engages after the cylinder has stopped moving and cannot be used to brake a moving rod.
The clamp is released by applying air to the dedicated G1/8 enclasp port. To prevent the rod from jumping abruptly, the air pressures on both sides of the piston must be balanced before unlocking. The cylinder itself operates on 3/8 PT ports.
