Fits when
- A compact-height cylinder is required with a published large bore
- The installed code or drawing identifies an ACT body
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.
Product matching reference
Compare the photo, drawing, and measurable details first
Identify from the photo
- Full ACT model code or cylinder label
- Published bore: 125, 140, 160, 200, or 250 mm
- Required stroke from the published 25–500 mm table
- Port, rod-end style, mounting-hole pattern, and installed clearance
Drawing reference
- Compare the ACT bore, stroke, port, rod-end, mounting-hole pattern, and installed clearance
- Use the published drawing dimensions for the matching bore
- For replacement work, include the complete label or drawing where the installed interface is critical
