AirTAC ACT Series Large-Bore Ultra-Thin Cylinders
ACT is a double-acting, large-bore ultra-thin cylinder series. Confirm the full ACT code, bore, stroke, port thread, rod-end style, and installed mounting dimensions before RFQ.

Avoid a wrong match
- Do not select by body height alone: ACT starts at 125 mm bore
- ACT-S in a label identifies the magnetic option, not a separate indexed product family
- Port size and mounting dimensions change across the published bore sizes

If the label is incomplete, send the readable parts together with a photo.

About ACT
ACT is a large-bore, double-acting ultra-thin cylinder series. It is not a routine variant of the smaller SDA, ACE, or ACQ families: the published ACT bores, body dimensions, mounting geometry, and port sizes must be checked against the installed cylinder.
