Airtac BSAID Clamp Cylinder BSAID100X800S
The AirTAC Airtac BSAID Clamp Cylinder BSAID100X800S 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 BSAID100X800S
The AirTAC BSAID100X800-S is a double-acting ISO 15552 profile cylinder featuring a rod extending from both ends and an integrated clamp-lock mechanism. A spring-applied, air-released gripper locks the piston rod at ANY position along its 800 mm travel, delivering a static holding force of 5500 N. Because it is a double-rod design, the thrust is equal in both directions at 3681 N (0.5 MPa). Remember that the holding force is a separate quantity from thrust; you must size the 5500 N clamp capacity against your static load, not the cylinder's propulsion power.
This enclasp mechanism operates via a third G1/8 unlock port (distinct from the 1/2 inch cylinder ports) and requires 0.15-0.7 MPa to release. The dual-rod architecture is specifically chosen so you can mount a workpiece on one end and a guide, counterweight, or position flag on the other, providing built-in anti-rotation and dual-side guidance. The variable air cushions only decelerate the piston near stroke ends; the clamp is what actually holds the load.

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 BSAID100X800S Is Used
Vertical Z-Axis Holding
Secures a 100 mm bore lifting axis at any intermediate height during power loss, relying on the 5500 N clamp rather than live air pressure to prevent drops.
Machining Position Lock
Freezes the dual-rod platform at a precise mid-stroke coordinate for machining or inspection, using the second rod end for a position flag.
Dual-Side Emergency Stop
Holds the load safely anywhere in the 800 mm travel during an E-stop, with balanced-pressure unlocking required to resume motion safely.
Is the Airtac BSAID Clamp Cylinder BSAID100X800S the Right Clamp-Lock?
Choose this 100 mm bore when an application demands 3681 N of equal push/pull force alongside robust mid-stroke holding. If your load is lighter, the 80 mm bore offers 2268 N thrust and a 3600 N hold; if you need more, the 125 mm provides 5734 N thrust and 8600 N holding force. Select this BSAID model over a stroke-end-only SAIL lock when you must secure the load anywhere in the 800 mm travel. If no intermediate holding is needed, a plain SAID cylinder suffices.
For safe operation, the clamp locks only after the rod has stopped; it cannot brake a moving load. It must be unlocked with balanced air pressures on both sides of the piston, or the rod may jump abruptly. Safety-critical applications require an independent external measure. This 800 mm stroke requires an external guide to prevent side-loading. Replacement requires a double-rod, 100 mm bore, 800 mm stroke, PT ports, and a -S magnet for CMSE (reed) or DMSE (electronic) sensors. BSAID mounting omits FB/CA/CB/CR, using Basic, FA, LB, TC, TCM1, or TCM2.
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 BSAID100X800S FAQ
It uses a spring-applied, air-released mechanism to grip the rod at any position with a 5500 N static holding force. It is bidirectional and holds equally whether the rod was extending or retracting.
No. The clamp locks only after the cylinder has stopped moving; it is not a dynamic brake. It must be released with balanced pressures to prevent the rod from jumping, and human-safety loads need an independent backup.
