Airtac BSAID Clamp Cylinder BSAID100X800
The AirTAC Airtac BSAID Clamp Cylinder BSAID100X800 is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 800mm 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 BSAID100X800
The AirTAC BSAID100X800 is a double-acting ISO 15552 profile cylinder featuring a double-rod design and an integrated clamp-lock mechanism. A spring-applied, air-released gripper clamps the piston rod to secure the load at any position along the 800mm stroke, delivering a static holding force of 5500 N. Because it is a double-rod unit, the thrust is equal in both directions at 3681 N (0.5 MPa), and having a rod out both ends allows you to mount a workpiece on one side and a guide or counterweight on the other for dual-side anti-rotation.
It is crucial to distinguish holding force from cylinder thrust: the 5500 N clamp force is a separate static rating from the 3681 N pneumatic thrust, so you must size the hold against the static load, not the thrust. The lock engages only after the rod has stopped, meaning it cannot brake a moving load. Furthermore, the clamp releases via a third G1/8 enclasp port, which requires balanced air pressure on both piston sides to prevent the rod from jumping abruptly upon unlock.

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 BSAID100X800 Is Used
Vertical Axis Hold
Secures a 100mm bore lifting platform at any height along the 800mm travel, preventing gravity drops when air pressure is removed.
Machining Position Lock
Holds a dual-sided workpiece carrier rigidly in place for intermediate machining or inspection stops without relying on pneumatic thrust.
Power Loss Safety
The spring-applied clamp immediately engages to freeze the double-rod position if the air supply drops, containing the load safely.
Is the Airtac BSAID Clamp Cylinder BSAID100X800 the Right Clamp-Lock?
Choose this 100mm bore if your application requires substantial equal-thrust action (3681 N both ways) combined with mid-stroke holding. If your load is lighter, stepping down to the 80mm bore offers 2268 N thrust and a 3600 N hold; if you need more brute force, the 125mm bore provides 5734 N thrust and an 8600 N hold. A plain SAID cylinder suffices if you only need double-rod motion without any intermediate holding. Choose this BSAID model over a SAIL stroke-end lock when you must secure the load anywhere in the travel.
This clamp locks only after the cylinder has fully stopped, and safety-critical loads require an additional independent safety measure. The 800mm stroke on this 25mm rod benefits from the M20x1.5 thread's rigidity, but because the stroke exceeds 300mm, an external guide is recommended to manage side loads. Replacement requires a double-rod 100x800 body with PT ports, and the mounting set omits FB, CA, CB, and CR brackets (using Basic, FA, LB, TC, TCM1, TCM2 only). A magnet (-S) is not specified for this unit, so CMSE or DMSE sensors cannot be used without modification.
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 BSAID100X800 FAQ
The 5500 N holding force is a static clamp rating separate from the cylinder's 3681 N pneumatic thrust. The clamp secures the load at any position after the rod stops, whereas the thrust dictates the dynamic push/pull capability.
The clamp unlocks via a third G1/8 port, but only when air pressures on both piston sides are balanced. If pressures are unbalanced, the rod can jump abruptly upon release. Additionally, it cannot brake a moving rod and only holds after the cylinder stops, so human-safety applications need an independent safety measure.
