The AirTAC Airtac BSAID Clamp Cylinder BSAID100X900S is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 900mm 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 BSAID100X900-S is a double-acting ISO 15552 profile cylinder featuring a double-rod design and a spring-applied, air-released clamp-lock. It secures the load at any position along its 900 mm stroke, delivering a static holding force of 5500 N. Because it is a double-rod unit, its thrust is identical in both directions at 3681 N (at 0.5 MPa), making it ideal for dual-side guidance. A rod out both ends allows you to mount a workpiece on one side and a counterweight or position flag on the other.
It is crucial to distinguish holding force from thrust: the 5500 N clamp grip is a separate static metric from the 3681 N pneumatic thrust. The clamp uses a third G1/8 enclasp port and requires a 0.15-0.7 MPa operating range. Remember that the variable air cushion only decelerates the piston near stroke ends; the clamp is the true holding device. The -S magnet works with AirTAC CMSE reed and DMSE electronic sensors.

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 100 mm bore vertical lifting platform at any point in its 900 mm travel, preventing gravity drops with 5500 N of static grip.
Spring-applied clamp engages instantly upon air loss, holding the double-rod payload exactly where it stopped mid-cycle.
Locks the extended rod during secondary machining or inspection, using the opposite rod end for a position flag.
Choose this 100 mm bore when an application requires holding a heavy load mid-stroke, as the 5500 N clamp vastly exceeds the 1400 N grip of a 50 mm bore. If locking is only needed at the stroke end, a plain SAIL saves space. For non-safety-critical positioning without power, BSAI works well, but note the clamp locks only after the rod stops and cannot brake moving loads. Always unlock with balanced piston pressures to prevent the rod from jumping.
This BSAID100X900-S features a 900 mm stroke (within the 1000 mm standard limit) and a 25 mm rod with an M20x1.5 thread. At this length, the unsupported rod needs an external guide to manage side loads. It uses PT tapered ports (1/2 inch cylinder, G1/8 enclasp) and accepts Basic, FA, LB, TC, TCM1, or TCM2 mountings (omitting FB/CA/CB/CR). The -S option supports CMSE/DMSE sensors.
Quick checklist
It provides a static holding force of 5500 N. The clamp locks the rod at any position bidirectionally, but it engages only after the cylinder has stopped moving.
Release requires balanced air pressure on both piston sides to prevent the rod from jumping. The -S magnet works with AirTAC CMSE reed and DMSE electronic sensors.
