The AirTAC Airtac BSAID Clamp Cylinder BSAID80X150 is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 150mm 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 3600 N.
The AirTAC BSAID80X150 is a double-acting ISO 15552 profile cylinder featuring a double-rod design and an integrated clamp-lock. A spring-applied, air-released mechanism grips the 25mm carbon steel rod at any position along its 150mm travel, delivering a static holding force of 3600 N. Because it is a double-rod unit, the thrust is equal in both directions at 2268 N (based on 0.5 MPa pull-side operation). It is crucial to distinguish this holding force from thrust: the 3600 N clamp rating dictates the static load capacity during a hold, whereas the 2268 N thrust drives the motion.
The double-rod configuration allows you to mount a workpiece on one end and a guide, counterweight, or position flag on the opposite end, providing dual-side guidance and anti-rotation. The clamp operates via a dedicated G1/8 enclasp port, separate from the 3/8 cylinder ports, and requires 0.15-0.7 MPa to release. Remember that the variable air cushion only decelerates the piston near stroke ends; the clamp itself is what secures 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 | 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.
Secures elevated platens at any intermediate height during power loss, using the 3600 N clamp to prevent gravity-driven drops.
Holds a dual-sided workpiece rigidly in place for machining or inspection, leveraging the anti-rotation benefit of the double rod.
Maintains a mid-stroke position safely when air supply is removed, provided the rod has already ceased motion.
Select this double-rod model when your mechanism requires equal force both ways and a rod out both ends for mounting external guides or flags. If you do not need the second rod, step down to the single-rod BSAI80X150. If your load is lighter, the BSAID63 offers 1402 N thrust and a 2200 N hold. The BSAID80X150 is chosen over a plain SAID when power-loss safety is required anywhere in the stroke, unlike SAIL which only locks at stroke ends.
Honest holding limits apply: the clamp locks only after the cylinder has stopped moving and cannot act as a brake. It must be unlocked with balanced air pressures on both sides of the piston, or the rod may jump abruptly. For human-safety-critical applications, add an independent safety measure. Replacement specs: 80mm bore, 150mm stroke, PT port threads, and mounting options limited to Basic, FA, LB, TC, TCM1, and TCM2 (omitting FB, CA, CB, CR). No magnet is specified for sensors.
Quick checklist
It provides a static holding force of 3600 N. The spring-applied clamp locks the rod at any position bidirectionally, but only after the cylinder has stopped moving; it cannot brake a moving load.
Air pressure must be balanced on both sides of the piston before unlocking via the G1/8 enclasp port. If pressures are unbalanced, the rod may jump abruptly upon release.
