The AirTAC SAIJ160 Adjustable Cylinder SAIJ160BX350-50 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 350mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAIJ160X350-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. This heavy-duty actuator uses a SUS304 stainless steel rod and a PT tapered G3/4 port to handle demanding industrial environments.
The integrated rear stopper allows precise end-position tuning during commissioning without adding external stops. It supports a narrower mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU lacks the magnet for CMSE or DMSE switches.

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Dial in the exact 300-350 mm end position for heavy pressing or forming operations during initial machine setup without swapping actuators.
Adapt a high-thrust conveyor diverter or stopper block on the fly when packaging dimensions change, utilizing the 50 mm adjustment window.
Replace rigid hard stops with a controlled pneumatic stopper to fine-tune the retraction point on large material handling equipment.
If a project demands less thrust, stepping down to a 125 mm bore yields 6136 N; if more power is needed, a 200 mm bore provides 15708 N. The adjustable stroke is ideal for product-size changeovers on a line, whereas a fixed SAI cylinder suits fixed-pitch machinery. Because the 350 mm stroke is substantial, an external guide is recommended to manage side loads.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 160 mm bore, 350 mm stroke, 50 mm adjustment, PT G3/4 port, and the SUS304 rod material. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for pilot-operated load holding, consider an AirTAC SAIL or BSAI cylinder.
Quick checklist
The rear adjuster acts as a mechanical stop that trims the effective travel. For this 350 mm stroke model, you can fine-tune the usable retraction window down to 300 mm without changing the cylinder or adding external stops.
