The AirTAC Airtac BSAID Clamp Cylinder BSAID100X350S is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 350mm 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.
The AirTAC BSAID100X350-S is a double-acting ISO 15552 profile cylinder featuring a rod out both ends and a spring-applied, air-released clamp-lock. It secures the load at any position along its 350 mm travel with 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), making it ideal for mounting a workpiece on one end and a counterweight or guide on the opposite end.
It is vital to distinguish this 5500 N static holding force from the cylinder's 3681 N thrust; the clamp only holds stationary loads and cannot brake a moving rod. The lock engages after the piston stops, requiring a third G1/8 enclasp port to release the grip. Remember that the variable air cushion only decelerates the piston near the stroke ends, while the clamp mechanism is what truly holds the load.

Specifications follow the official AirTAC BSAI datasheet (ISO 15552). Operating pressure is 0.15–0.7 MPa (lower than a plain SAI). Port options: PT / G.
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.
| 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.
Secures a vertically lifted load at any point in the 350 mm travel to prevent drops during power loss.
Holds a dual-sided workpiece rigidly in place for machining or inspection without relying on live air pressure.
Uses the double-rod design to mount a tool on one end and a position flag on the other, locking precisely at station stops.
Choose this double-rod model when you need symmetrical force (3681 N both ways) and dual-end mounting for anti-rotation or tool balancing. If your application only requires locking at the stroke end, a plain SAIL cylinder suffices; if you need to hold mid-stroke securely, this BSAID is the correct choice. For lighter loads, the 80 mm bore offers 2268 N thrust and 3600 N holding force.
This clamp locks only after the cylinder has stopped and must be unlocked with balanced air pressures to prevent the rod from jumping abruptly. For safety-critical applications, an independent external measure is required. This unit includes a -S magnet for CMSE (reed) and DMSE (electronic) sensors, uses PT ports, and accepts Basic, FA, LB, TC, TCM1, or TCM2 mounts. Given the 350 mm stroke and M20x1.5 rod, external guidance is recommended to handle side loads.
Quick checklist
The spring-applied clamp provides a static holding force of 5500 N at any position along the stroke. This is separate from the 3681 N thrust and only holds the load after the rod has stopped moving.
The clamp is released via a third G1/8 enclasp port. You must balance the air pressures on both sides of the piston before unlocking, otherwise the rod may move abruptly. It is not a braking device for moving loads.
